Keep the cutting edge   WARNING:   sharp and clean for best performance and to   reduce the risk of injury. Follow instructions for   lubricating and changing accessories. Inspect the   battery charger cord periodically, and if damaged,   have it replaced or repaired by an authorized   service dealer.   Do not attempt to operate this unit until you have   read thoroughly and understand completely all   instructions, safety information, etc. contained in   this manual. Failure to comply can result in   accidents involving fire, electric shock, or   serious personal injury.   ■ Keep handles dry, clean, and free of oil and grease.   ■ Do not operate a chain saw that is damaged,   improperly adjusted, or not completely and securely   assembled. Chain should stop turning when the   trigger is released. If the chain turns after the   trigger has been released, have the unit serviced   by your nearest Ryobi service dealer.   READ ALL INSTRUCTIONS   BASIC SAFETY PRECAUTIONS   ■ Do not operate a chain saw with one hand! Use a   firm grip with thumbs and fingers encircling the   chain saw handles. Serious injury to the operator,   helpers, bystanders, or any combination of these   persons may result from one-handed operation. A   chain saw is intended for two-handed use.   ■ Check for damaged parts. Any part or guard that   has been damaged should be carefully checked to   determine that it will operate properly and perform   its intended function. Check for alignment of   moving parts, binding of moving parts, breakage of   parts, mounting, and any other conditions that may   affect its operation. A guard or other part that is   damaged should be properly repaired or replaced   by an authorized service dealer unless otherwise   indicated elsewhere in this manual.   ■ Always be aware of what you are doing when using   the chain saw. Use common sense. Do not operate   the chain saw when you are tired, ill, or under the   influence of alcohol, drugs, or medication.   ■ Stay alert and pay attention to what you are doing.   Use common sense when using this unit.   ■ All chain saw service, other than the items listed in   the operation and maintenance sections, should be   performed by your nearest Ryobi service dealer.   ■ Keep all parts of your body away from the saw   chain when the unit is running.   ■ Always carry the chain saw by the front handle with   the unit stopped and the guide bar and saw chain   positioned to the rear. When transporting your   chain saw, use the appropriate guide bar scabbard.   ■ Do not use in the rain, snow or wet conditions.   ■ Always maintain a proper stance.   ■ Do not adapt your powerhead to a bow guide or   use it to power any attachments or devices not   listed for your saw.   ■ Never let anyone use your chain saw who has not   received adequate instructions in its proper use.   This applies to rentals as well as privately owned   saws.   ■ Do not cut vines and/or small underbrush.   SAFETY APPAREL   ■ Before you start the unit, make sure the saw chain   is not contacting any object.   ■ Wear snug fitting clothing. Always wear heavy, long   pants, overalls, jeans or chaps made of cut resis-   tant material or ones that contain cut resistant   inserts. Wear non-slip safety footwear. Wear non-   slip heavy duty gloves to improve your grip and to   protect your hands. Do not wear jewelry, short   pants, sandals, or go barefoot. Do not wear loose   fitting clothing, which could be drawn into the motor   or catch the chain or underbrush. Secure hair so it   is above shoulder level.   ■ Stop the chain saw before setting it down. Do not   leave the unit running unattended.   ■ To avoid accidental starting, never carry the unit   with your finger on the trigger.   ■ Wear eye protection which is marked to comply   with ANSI Z87.1 as well as hearing and head   protection when operating this equipment.   3 Download from Www.Somanuals.com.

Contact at the   upper portion of the tip of the guide bar can cause   the chain to dig into the object and stop the chain   for an instant. The result is a lightning fast, reverse   reaction which kicks the guide bar up and back   toward the operator. If the saw chain is pinched   along the top of the guide bar, the guide bar can be   driven rapidly back toward the operator. Either of   these reactions can cause loss of saw control   which can result in serious injury. Do not rely   exclusively upon the safety devices built into your   saw. As a chain saw user, you should take several   steps to keep your cutting jobs free from accident   or injury.   ■ Follow the sharpening and maintenance instruc-   tions for the saw chain.   ROTATIONAL   KICKBACK   ■ The following precautions should be followed   to minimize kickback:   1. Always grip the saw firmly with both hands. Hold   the saw firmly with both hands when the unit is   running. Place your right hand on the rear   handle and the left hand on the front handle with   your thumbs and fingers encircling the chain   saw handles. A firm grip together with a stiff left   arm will help you maintain control of the saw if   kickback occurs.   BAR SHOWN WITHOUT SAFE-T-TIP® NOSE GUARD   FOR ILLUSTRATION PURPOSES ONLY.   Fig. 1   KICKBACK   DANGER ZONE   2. Make sure that the area in which you are cutting   is free from obstructions. Do not let the nose of   the guide bar contact a log, branch, fence, or   any other obstruction that could be hit while you   are operating the saw.   3. Always cut with the unit running at full speed.   Fully squeeze the throttle trigger and maintain a   steady cutting speed.   Fig. 2   4. Use replacement parts such as low kickback   chain, SAFE-T-TIP anti-kickback nose guards,   chain brakes and special guide bars that reduce   the risks associated with rotational kickback.   Use only the replacement guide bars and low   kickback chains specified by the manufacturer   for your saw.   ■ With a basic understanding of kickback, you can   reduce or eliminate the element of surprise. Sud-   den surprise contributes to accidents.   ■ Keep proper footing and balance at all times.   4 Download from Www.Somanuals.com.

Thus, the operator must be   ready to control the PULL when cutting on the   bottom edge of the bar, and PUSH when cutting   along the top edge. See Figure 3.   IN THE CUTTING/WORK AREA   ■ Do not operate a chain saw in a tree, on a ladder,   or scaffold; this is extremely dangerous.   ■ Keep ALL children, bystanders, visitors, and   animals out of the work area while starting or   cutting with the chain saw.   PULL   NOTE: The size of the work area depends on the   job being performed as well as the size tree or   work piece involved. For example, felling a tree   requires a larger work area than making bucking   cuts.   ■ Never start cutting until you have a clear work   area, secure footing, and a planned retreat path   from the falling tree. Cluttered area invite injuries.   ■ Do not expose the chain saw to rain.   ■ Do not use the chain saw in damp or wet locations.   ■ Do not use the chain saw near flammable liquids,   gases, or in any type of explosive atmosphere.   ■ Use extreme caution when cutting small size brush   and saplings, because slender material may catch   the saw chain and be whipped toward you or pull   you off balance.   PUSH   Fig. 3   ■ When cutting a limb that is under tension, be alert   for spring back so that you will not be struck when   the tension in the wood fibers is released.   ■ Do not force the chain saw. The job can be per-   formed better and safer at the rate for which it was   intended.   ■ Always use the right product for your application.   The chain saw should be used for cutting wood   only. Never use the chain saw to cut plastic,   masonry or non-wood building materials.   ■ Do not use the chain saw for purposes not in-   tended.   ■ Store idle chain saw when not in use, chain saw   should be stored in a dry and high or locked area   out of the reach of children. When storing chain   saw, remove battery and place the scabbard on the   bar and chain or store the chain saw in a carry   case.   ■ Remove the battery pack from the chain saw   before cleaning, servicing, storing, removing   material from the unit, changing accessories such   as the bar and chain, or when not in use.   5 Download from Www.Somanuals.com.

Be aware of possible haz-   ards even when unit is not operating.   SAFE-T-TIP® Anti-Kickback Nose Guard   The SAFE-T-TIP® prevents kickback from happening,   because it covers the tip of the bar where kickback is   generated. Never attempt any kind of cutting where the   SAFE-T-TIP® would have to be removed from the bar   tip.   ■ Remove the battery pack from the chain saw before   cleaning, servicing, storing, removing material from   the unit, changing accessories such as the bar and   chain, or when not in use.   ■ A battery pack must be recharged only with the   specified charger for the battery pack. A charger   that may be suitable for one type of battery pack   may create a risk of fire when used with another   battery pack. Use battery pack only with charger   listed.   SAFE-T-TIP   BATTERY PACK:   Item # 1322401,   1323303, 130224007,   or 130256001   CHARGER:   Item # 1423701   Fig. 4   ■ To reduce the risk of explosion and possible injury,   Do not place battery units or their batteries near fire   or heat.   LOW KICKBACK SAW CHAIN   ■ Do not open or mutilate the battery pack. Released   electrolyte is corrosive and may cause damage to   the eyes or skin. It may be toxic if swallowed.   The rakers (depth gauges) ahead of each cutter can   minimize the force of a kickback reaction by preventing   the cutters from digging in too deeply at the kickback   zone. Only use replacement chain that is equivalent to   original chain or has been certified as low kickback   chain per ANSI B175.1.   ■ A damaged battery pack is subject to explosion. To   avoid serious personal injury, properly dispose of a   damaged battery pack.   ■ Batteries vent hydrogen gas and can explode in the   presence of a source of ignition, such as a pilot   light. To reduce the risk of serious personal injury,   never use any cordless product in the presence of   open flame. An exploded battery pack can propel   debris and chemicals. If exposed, flush with water   immediately.   Low kickback saw chain is chain that has met the   kickback performance requirements of ANSI B175.1 -   1991 (American National Standard for Power Tools -   Gasoline-Powered Chain Saws-Safety Requirements)   when tested on the representative sample of chain   saws below 3.8 c.i.d. specified in ANSI B175.1 - 1991.   As saw chains are sharpened during their useful life,   they lose some of the low kickback qualities and extra   caution should be used.   ■ Do not charge unit in a damp or wet location.   Following this rule will reduce the risk of electric   shock.   GUIDE BARS   ■ For best results, your battery unit should be   charged in a location where the temperature is   more than 50°F (10°C) but less than 100°F (38°C).   Do not store outside or in vehicles.   Generally, guide bars with small radius tips have   somewhat lower kickback potentials.   When making a replacement, be sure to order one of   the Ryobi bars listed for your saw in this operator's   manual. The proper size SAFE-T-TIP® nose guard   comes installed on the bar. Use only guide bars that   have a provision for mounting the SAFE-T-TIP®.   ■ Under extreme usage or temperature conditions,   battery pack leakage may occur. If liquid comes in   contact with your skin, wash immediately with soap   and water, then neutralize with lemon juice or   vinegar. If liquid gets into your eyes, flush them with   clean water for at least 10 minutes, then seek   immediate medical attention.   6 Download from Www.Somanuals.com.

Wear non-slip gloves for maximum grip and protec-   tion.   2. Hold the saw firmly with both hands. Always keep   your left hand on the front handle and your right   hand on the rear handle so that your body is to the   left of the chain line.   Fig. 10   15   Download from Www.Somanuals.com. All Manuals Search And Download.   OPERATION   WARNING:   Never use a left-handed (cross-handed) grip, or   any stance which would place your body or arm   across the chain line.   3. Maintain a proper grip on the saw whenever the   unit is running. The fingers should encircle the   handle and the thumb is wrapped under the handle-   bar. This grip is least likely to be broken (by a   kickback or other sudden reaction of the saw). Any   grip in which the thumb and fingers are on the   same side of the handle, is dangerous because a   slight kick of the saw can cause loss of control.   CHAIN LINE   Fig. 12   WARNING:   Do not operate the throttle trigger with your left   hand and hold the front handle with your right   hand. Never allow any part of your body to be in   the chain line while operating a saw.   PROPER GRIP   IMPROPER   GRIP   Fig. 11   16   Download from Www.Somanuals.com.

Take the proper stance in front of the wood with the   saw off.   ■ Always cut with both feet on solid ground to prevent   being pulled off balance.   2. Squeeze the trigger and let the chain accelerate to   full speed before entering the cut.   ■ Do not cut above chest height, as a saw held   higher is difficult to control against kickback forces.   3. Begin cutting with the saw against the log.   4. Keep the unit running the entire time you are   cutting, maintain a steady speed.   ■ Do not fell trees near electrical wires or buildings.   Leave this operation for professionals.   5. Allow the chain to cut for you; exert only light   downward pressure. If you force the cut, damage to   the bar, chain, or unit can result.   ■ Cut only when visibility and light are adequate for   you to see clearly.   6. Release the trigger as soon as the cut is com-   pleted, allowing the chain to stop. If you run the   saw without a cutting load, unnecessary wear can   occur to the chain, bar, and unit.   TREE FELLING   Unusual Hazardous Tree Felling Conditions   Do not fell trees during periods of high wind or heavy   precipitation. Wait to do your cutting until the hazard   has ended.   7. Do not put pressure on the saw at the end of the   cut.   WORK AREA PRECAUTIONS   ■ Cut only wood or materials made from wood; no   sheet metal, no plastics, no masonry, no non-wood   building materials.   WARNING:   Do not cut down trees having an extreme lean or   large trees that have rotten limbs, loose bark, or   hollow trunks. Have these trees pushed or   dragged down with heavy equipment, then cut   them up.   ■ Never allow children to operate your saw. Allow no   person to use this chain saw who has not read this   Operator's Manual or received adequate instruc-   tions for the safe and proper use of this chain saw.   ■ When felling a tree, keep everyone - helpers,   bystanders, children, and animals a safe distance   from the cutting area. During felling operations, the   safe distance should be a least twice the height of   the largest trees in the felling area. During bucking   operations, keep a minimum distance of 15 feet   (4.5 m) between workers.Trees should not be felled   in a manner that would endanger any person, strike   any utility line or cause any property damage. If the   tree does make contact with any utility line, the   utility company should be notified immediately.   WARNING:   Do not cut trees near electrical wires or   buildings.   WARNING:   Check the tree for damaged or dead branches   that could fall and hit you during felling.   17   Download from Www.Somanuals.com. All Manuals Search And Download.   OPERATION   PLANNED LINE OF FALL   WARNING:   Periodically glance at the top of the tree during   the backcut to assure the tree is going to fall in   the desired direction.   WARNING:   If the tree starts to fall in the wrong direction, or   if the saw gets caught or hung up during the fall,   leave the saw and save yourself!   90°   ■ Felling a tree - When bucking and felling operations   are being performed by two or more persons, at the   same time, the felling operation should be sepa-   rated from the bucking operation by a distance of   at least twice the height of the tree being felled.   Trees should not be felled in a manner that would   endanger any person, strike any utility line or cause   any property damage. If the tree does make   contact with any utility line, the utility company   should be notified immediately.   SAFE   RETREAT   ZONE   PLANNED PATH OF SAFE RETREAT   135° FROM PLANNED LINE OF FALL   SAFE   RETREAT   ZONE   ■ Before any cuts are started, pick your escape route   (or routes in case the intended route is blocked);   clear the immediate area around the tree and make   sure there are no obstructions in your planned path   of retreat. Clear path of safe retreat approximately   135° from planned line of fall. The retreat path   should extend back and diagonally to the rear of the   expected line of fall. See Figure 14.   135°   PLANNED   LINE OF FALL   45°   90°   45°   135°   ■ Before felling is started consider the force and   direction of the wind, the lean and balance of the   tree, and the location of large limbs. These things   influence the direction in which the tree will fall. Do   not try to fell a tree along a line different from its   natural line of fall.   SAFE   RETREAT   ZONE   Fig. 14   ■ The chain saw operator should keep on the uphill   side of the terrain as the tree is likely to roll or slide   downhill after it is felled.   ■ Remove dirt, stones, loose bark, nails, staples, and   wire from the tree where felling cuts are to be   made.   HINGE   2 IN. (5 CM) OR 1/10 DIA   ■ Notched Undercut. Cut a notch about 1/3 the   diameter of the tree, perpendicular to the direction   of fall. Make the cuts of the notch so they intersect   at a right angle to the line of fall. This notch should   be cleaned out to leave a straight line. To keep the   weight of the wood off the saw, always make the   lower cut of the notch before the upper cut. See   Figure 15.   NOTCH -   APPROX. 1/3   DIAMETER OF   TRUNK   BACK CUT   2 IN. (5 CM)   Fig. 15   18   Download from Www.Somanuals.com. All Manuals Search And Download.   OPERATION   ■ Felling Backcut. The backcut is always made   level and horizontal, and at a minimum of 2 inches   (5 cm) above the horizontal cut of the notch. See   Figures 15 and 16.   ■ Never cut through to the notch. Always leave a   band of wood between the notch and backcut   (approximately 2 inches (5 cm) or 1/10 the diameter   of the tree). This is called "hinge" or “hingewood.”   It controls the fall of the tree and prevents slipping   or twisting or shoot-back of the tree off the stump.   See Figures 15 and 16.   Fig. 17   WEDGE   ■ On large diameter trees, stop the back cut before it   is deep enough for the tree to either fall or settle   back on the stump. Then insert soft wooden or   plastic wedges into the cut so they do not touch the   chain. The wedges can be driven in, little by little, to   help jack the tree over. See Figure 17.   BUCKING   See Figures 18 through 21.   Bucking is the term used for cutting a fallen tree to the   desired log length.   NOTE: When bucking or felling with a wedge, it   may be necessary to remove the SAFE-T-TIP®   anti-kickback device to allow the bar to be drawn   through the cut. After the cut is complete, the tip   should be reinstalled immediately.   ■ Always make sure your footing is secure and your   weight is distributed evenly on both feet.   ■ ■ Cut only one log at a time.   Support small logs on a saw horse or another log   while bucking.   ■ As tree starts to fall, stop the chain saw and put it   down immediately. Retreat along the cleared path,   but watch the action in case something falls your   way. Be alert for overhead limbs or branches that   may fall and watch your footing.   ■ Keep a clear cutting area. Make sure that no objects   can contact the guide bar nose and chain during   cutting, this can cause kickback. To avoid the dan-   ger, keep the SAFE-T-TIP® anti-kickback device   attachedwhilecutting. Referto“PrecautionsAgainst   Kickback” earlier in this manual.   WARNING:   Never cut through to the notch when making a   backcut. The hinge controls the fall of the tree,   this is the section of wood between the notch   and backcut.   KICKBACK   Fig. 18   NOTCH   BACK CUT   Fig. 16   HINGE   19   Download from Www.Somanuals.com.

To maintain complete control of the   chain saw when cutting through the log, release the   cutting pressure near the end of the cut without   relaxing your grip on the chain saw handles. Do not   letthechaincontacttheground. Aftercompletingthe   cut, wait for the saw chain to stop before your move   the chain saw. Always stop the motor before moving   from tree to tree. See Figure 19.   When the log is supported along its entire length, it   should be cut from the top or overbucking.   When the log is supported on one end, cut 1/3 the   diameter from the underside or underbucking. Then   make the finishing cut by overbucking to meet the first   cut.   As the log is being cut, it will tend to bend. The saw   can become pinched or hung in the log if you make the   first cut deeper than 1/3 of the diameter of the log.   ■ Sometimes it is impossible to avoid pinching (with   juststandardcuttingtechniques)ordifficulttopredict   which way a log will settle when cut. To avoid   pinching while cutting, rotate or move the log so that   the pinch is eliminated.   Give special attention to logs under stress to prevent   the bar and chain from pinching.   When bucking on a slope, always stand on the uphill   side of the log as shown in Figure 19. When “cutting   through”, to maintain complete control of the chain   saw, release the cutting pressure near the end of the   cut without relaxing your grip on the chain saw   handles. Do not let the chain contact the ground. After   completing the cut, wait for the saw chain to stop   before your move the chain saw. Always stop the   motor before moving from tree to tree.

Do not   stand on ladders, platforms, a log or in any   position which can cause you to lose your   balance or control of the saw.   OVERBUCKING   Begin on the top side of the log with the bottom of the   saw against the log; exert light pressure downward.   Note that the saw will tend to pull away from you.   UNDERBUCKING   LIMBING   See Figure 22.   Begin on the under side of the log with the top of the   saw against the log; exert light pressure upward.   During underbucking, the saw will tend to push back at   you. Be prepared for this reaction and hold the saw   firmly to maintain control.   Limbing is removing branches from a fallen tree.   ■ Work slowly, keeping both hands on the chain saw   with a firm grip. Always make sure your footing is   secure and your weight is distributed evenly on   both feet.   ■ Leave the larger support limbs under the tree to   keep the tree off the ground while cutting.   OVERBUCKING   ■ Limbs should be cut one at a time. Remove the cut   limbs from the work area often to help keep the   work area clean and safe.   ■ Branches under tension should be cut from the   bottom up to avoid binding the chain saw.   ■ Keep the tree between you and the chain saw while   limbing. Cut from the side of the tree opposite the   branch you are cutting.   UNDERBUCKING   3 2 1 4 CUT LIMBS ONE AT A TIME AND LEAVE SUPPORT   LIMBS UNDER TREE UNTIL LOG IS CUT   Fig. 21   Fig. 22   21   Download from Www.Somanuals.com.

Always make sure your footing is   secure and your weight is distributed evenly on   both feet.   ■ Do not cut from a ladder, this is extremely danger-   ous. Leave this operation for professionals.   FIRST CUT   1/3 DIAMETER   ■ Do not cut above chest height as a saw held higher   is difficult to control against kickback.   ■ When pruning trees it is important not to make the   finishing cut next to the main limb or trunk until you   have cut off the limb further out to reduce the   weight. This prevents stripping the bark from the   main member.   FINISHING CUT   Fig. 23   1. Underbuck the branch 1/3 through for your first   cut.   2. Your second cut should overbuck to drop the   branch off.   SPRINGPOLE   3. Now make your finishing cut smoothly and   neatly against the main member so the bark will   grow back to seal the wound.   WARNING:   Fig. 24   If the limbs to be pruned are above chest height,   hire a professional to perform the pruning.   SPRINGPOLES   See Figure 24.   WARNING:   Springpoles are dangerous and could strike the   operator, causing the operator to lose control of   the chain saw. This could result in severe or   fatal injury to the operator.   A springpole is any log, branch, rooted stump, or   sapling which is bent under tension by other wood so   that it springs back if the wood holding it is cut or   removed. On a fallen tree, a rooted stump has a high   potential of springing back to the upright position   during the bucking cut to separate the log from the   stump. Watch out for springpoles, they are dangerous.   22   Download from Www.Somanuals.com.

The chain requires sharpening when   the wood chips are small and powdery, the chain must   be forced through the wood during cutting, or the chain   cuts to one side. During maintenance of your chain,   consider the following:   CHECK FOR WEAR OR   DAMAGE   ■ Improper filing angle of the side plate can increase   the risk of a severe kickback.   ■ Raker (depth gauge) clearance.   ■ Too low increases the potential for kickback.   ■ Not low enough decreases cutting ability.   ■ If cutter teeth have hit hard objects such as nails   and stones, or have been abraded by mud or sand   on the wood, have service dealer sharpen chain.   Fig. 33   NOTE: Inspect the drive sprocket for wear or damage   when replacing the chain. If signs of wear or damage   are present in the areas indicated, have the drive   sprocket replaced by a Ryobi Service dealer.   HOW TO SHARPEN THE CUTTERS   See Figure 34 and 35.   Be careful to file all cutters to the specified angles and   to the same length, as fast cutting can be obtained   only when all cutters are uniform.   1. Wear gloves for protection. Properly tension the   chain prior to sharpening. Refer to “Chain Tension   Section” earlier in this manual. Do all of your filing   at the mid-point of the bar.   Fig. 34   2. Use A 5/32 in. diameter round file and holder.   3. Keep the file level with the top plate of the tooth. Do   not let the file dip or rock.   4. Using light but firm pressure, stroke towards the   front corner of the tooth.   Lift file away from the steel on each return stroke.   26   Download from Www.Somanuals.com.

Then move to the   other side and file the right hand cutters in the   opposite direction. Occasionally remove filings from   the file with a wire brush.   WARNING:   Improper chain sharpening increases the   potential of kickback.   RIGHT HAND   CUTTERS   Fig. 35   WARNING:   Failure to replace or repair damaged chain can   cause serious injury.   CORRECT TOP PLATE   FILING ANGLE   INCORRECT TOP PLATE   FILING ANGLE   LESS   THAN 30°   MORE   THAN 30°   WARNING:   30°   The saw chain is very sharp, always wear   protective gloves when performing maintenance   to the chain.   Fig. 36   TOP PLATE FILING ANGLE   See Figure 36.   ■ CORRECT 30° - File holders are marked with guide   marks to align file properly to produce correct top   plate angle.   CORRECT SIDE   PLATE FILING   ANGLE   INCORRECT SIDE PLATE   FILING ANGLE   ■ LESS THAN 30° - For Cross Cutting.   ■ MORE THAN 30° - Feathered Edge Dulls Quickly.   HOOK   BACKWARD   SLOPE   SIDE PLATE ANGLE   See Figure 37.   80°   ■ CORRECT- 80o Produced automatically if correct   diameter file is used in file holder.   ■ HOOK- “Grabs” and dulls quickly. Increases   potential of KICKBACK.   Fig. 37   Results from using a file with diameter too small, or   file held too low.   ■ BACKWARD SLOPE- Needs too much feed   pressure, causes excessive wear to bar and chain.   RAKER CLEARANCE   .025 in. (0.6 mm)   Results from using a file with diameter too large, or   file held too high.   DEPTH GAUGE CLEARANCE   See Figure 38.   1. The depth gauge should be maintained at a clear-   ance of .025 in. (0.6 mm). Use a depth gauge tool for   checking the depth gauge clearances.   Fig. 38   2. Every time the chain is filed, check the depth gauge   clearance.   27   Download from Www.Somanuals.com. All Manuals Search And Download.   MAINTENANCE   Use a Flat File and a Depth Gauge Jointer to lower all   gauges uniformly. Depth gauge jointers are available in   .020 in. to .035 in. (0.5 mm to 0.9 mm). Use a .025 in.   (0.6 mm) depth gauge jointer. After lowering each   depth gauge, restore original shape by rounding the   front. Be careful not to damage adjoining drive links   with the edge of the file. See Figures 39 and 40.   DEPTH GAUGE JOINTER   Depth gauges must be adjusted with the flat file in the   same direction the adjoining cutter was filed with the   round file. Use care not to contact cutter face with flat   file when adjusting depth gauges.   FLAT FILE   Fig. 39   GUIDE BAR MAINTENANCE   See Figure 41.   When the guide bar shows signs of wear, reverse it   on the saw to distribute the wear for maximum bar   life. The bar should be cleaned every day of use and   checked for wear and damage.   RESTORE ORIGINAL   SHAPE BY ROUNDING   THE FRONT   Feathering or burring of the bar rails is a normal   process of bar wear. Such faults should be smoothed   with a file as soon as they occur.   A bar with any of the following faults should be re-   placed.   Fig. 40   ■ Wear inside the bar rails which permits the chain to   lay over sideways.   ■ Bent guide bar.   ■ Cracked or broken rails.   ■ Spread rails.   In addition, guide bars with a sprocket at their tip must   be lubricated weekly with a grease syringe to extend   the guide bar life. Using a grease syringe, lubricate   weekly in the lubricating hole. See Figure x.   LUBRICATING HOLE   Turn the guide bar and check that the lubrication holes   and chain groove are free from impurities.   Fig. 41   REVERSING THE GUIDE BAR   See Figures 41, 42, and 43.   1.
