SECTION 3: IMPORTANT SAFE OPERATION PRACTICES  
This symbol points out important safety instructions which, if not followed, could endanger the  
personal safety and/or property of yourself and others. Read and follow all instructions in this manual  
before attempting to operate your lawn mower. Failure to comply with these instructions may result in  
personal injury. When you see this symbol—heed its warning.  
Your lawn mower was built to be operated according to the rules for safe operation in this manual.  
DANGER:  
As with any type of power equipment, carelessness or error on the part of the operator can result in  
serious injury. If the operator violates any of these rules, he/she may cause serious injury to  
himself/herself or others.  
• Never pull the mower toward you while you are  
walking. If you must back the mower away from a  
wall or obstruction first look down and behind, and  
then follow these steps:  
1. GENERAL OPERATION  
• Read this owner’s guide carefully in its entirety  
before attempting to assemble this machine. Read,  
understand, and follow all instructions on the  
machine and in the manual(s) before operation. Be  
completely familiar with the controls and the proper  
use of this machine before operating it. Keep this  
manual in a safe place for future and regular  
reference and for ordering replacement parts.  
• Your rotary mower is a precision piece of power  
equipment, not a plaything. Therefore, exercise  
extreme caution at all times. Your unit has been  
designed to perform one job: to mow grass. Do not  
use it for any other purpose.  
• Never allow children under 14 years old to operate  
a power mower. Children 14 years old and over  
should only operate mower under close parental  
supervision. Only responsible individuals who are  
familiar with these rules of safe operation should be  
allowed to use your mower.  
• Keep the area of operation clear of all persons,  
particularly small children and pets. Stop engine  
when they are in the vicinity of your mower to help  
prevent blade contact or thrown object injury.  
Although the area of operation should be  
completely cleared of foreign objects, an object  
may have been overlooked and could be  
accidentally thrown by the mower in any direction  
and cause serious personal injury to the operator or  
any others allowed in the area.  
• Thoroughly inspect the area where the equipment  
is to be used. Remove all stones, sticks, wire,  
bones, toys and other foreign objects which could  
be picked up and thrown by the mower in any  
direction and cause serious personal injury to the  
operator or any others allowed in the area. Plan  
your mowing pattern to avoid discharge of material  
toward roads, sidewalks, bystanders and the like.  
To help avoid a thrown object’s injury, keep  
children, bystanders and helpers at least 75 feet  
from the mower while it is in operation.  
• Step back from the mower to fully extend your  
arms.  
• Be sure you are well balanced with sure footing.  
• Pull the mower back slowly, no more than half way  
toward you.  
• Repeat these steps as needed.  
• Do not operate the mower while under the  
influence of alcohol or drugs.  
• The blade control handle is a safety device. Never  
attempt to bypass its operation. Doing so makes  
the safety device inoperative and may result in  
personal injury through contact with the rotating  
blade. The blade control handle must operate  
easily in both directions and automatically return to  
the disengaged position when released.  
• Never operate the mower in wet grass. Always be  
sure of your footing. A slip and fall can cause  
serious personal injury. Keep a firm hold on the  
handle and walk, never run. Mow only in daylight or  
in good artificial light.  
• Stop the blade when crossing gravel drives, walks  
or roads.  
• If the equipment should start to vibrate abnormally,  
stop the engine and check immediately for the  
cause. Vibration is generally a warning of trouble.  
• Shut the engine off and wait until the blade comes  
to a complete stop before removing the grass  
catcher or unclogging the chute. The cutting blade  
continues to rotate for a few seconds after the  
engine is shut off. Never place any part of the body  
in the blade area until you are sure the blade has  
stopped rotating.  
• Never operate mower without proper guards, grass  
catcher, plates or other safety protective devices in  
place.  
• Muffler and engine become hot and can cause a  
burn. Do not touch.  
• Only use accessories approved for this machine by  
the manufacturer. Read, understand, and follow all  
instructions provided with the approved accessory.  
• Always wear safety glasses or safety goggles  
during operation or while performing an adjustment  
or repair, to protect eyes from foreign objects that  
may be thrown from the machine in any direction.  
• Wear sturdy, rough-soled work shoes and close-  
fitting slacks and shirts. Shirts and pants that cover  
the arms and legs and steel-toed shoes are  
recommended. Do not wear loose fitting clothes or  
jewelry. They can be caught in moving parts. Never  
operate a unit in bare feet, sandals, or sneakers.  
• Do not put hands or feet near or under rotating  
parts. Keep clear of discharge opening at all times  
as the rotating blade can cause injury.  
• If situations occur which are not covered in this  
manual, use care and good judgment. Contact your  
dealer for assistance.  
• Do not adjust the throttle control with the engine  
running.  
2. SLOPE OPERATION  
For your safety, use the slope gauge included as part of this  
manual to measure slopes before operating this unit on a  
sloped or hilly area. If the slope is greater than 15 degrees  
as shown on the slope gauge, do not operate this mower.  
• Many injuries occur as a result of the mower being  
pulled over the foot during a fall. Do not hang on to  
the mower if you are falling; release the handle  
immediately.

DO:  
• Keep all nuts, bolts, and screws tight to be sure the  
equipment is in safe working condition.  
• Mow across the face of slopes; never up and down.  
Exercise extreme caution when changing direction  
on slopes.  
• Never tamper with safety devices. Check their  
proper operation regularly.  
• After striking a foreign object, stop the engine,  
remove the wire from the spark plug, and  
thoroughly inspect the mower for any damage.  
Repair the damage before starting and operating  
the mower.  
• Never attempt to make a wheel or cutting height  
adjustment while the engine is running.  
• Grass catcher components are subject to wear,  
damage and deterioration, which could expose  
moving parts or allow objects to be thrown. For  
safety protection, frequently check components and  
replace with manufacturer’s recommended parts,  
when necessary.  
• Mower blades are sharp and can cut. Wrap the  
blade(s) or wear gloves, and use extra caution  
when servicing them.  
• Watch for holes, ruts, hidden objects, or bumps.  
Tall grass can hide obstacles.  
• Always be sure of your footing. A slip and fall can  
cause serious personal injury. If you feel you are  
losing your balance release the blade control  
handle immediately and the blade will stop in less  
than 3 seconds.  
DO NOT:  
• Do not mow near drop-offs, ditches or  
embankments. The operator could lose footing or  
balance.  
• Do not mow slopes greater than 15 degrees as  
shown on the slope gauge.  
• Do not mow on wet grass. Reduced footing could  
cause slipping.  
• Do not change the engine governor setting or  
overspeed the engine. Excessive engine speeds  
are dangerous.  
3. CHILDREN  
Tragic accidents can occur if the operator is not alert to the  
presence of children. Children are often attracted to the  
mower and the mowing activity. Never assume that children  
will remain where you last saw them.  
Your Responsibility  
• Restrict the use of this power machine to persons  
who read, understand and follow the warnings and  
instructions in this manual and on the machine.  
• Following are representations of the safety labels  
on your lawn mower. Maintain safety while  
operating the mower.  
• Keep children out of the mowing area and under  
the watchful care of a responsible adult other than  
the operator.  
• Be alert and turn mower off if a child enters the  
area.  
• Before and while moving backwards, look behind  
and down for small children.  
• Never allow children under age 14 to operate the  
mower.  
• Use extreme care when approaching blind corners,  
shrubs, trees, or other objects that may obscure  
your vision of a child or hazard.  
4. SERVICE  
• Use extreme care in handling gasoline and other  
fuels. They are extremely flammable and the  
vapors are explosive.  
• Use only an approved gasoline container.  
• Never remove gas cap or add fuel while the engine  
is running. Allow engine to cool at least two  
minutes before refueling.  
• Replace gasoline cap securely and wipe off any  
spilled gasoline before starting the engine as it may  
cause a fire or explosion.  
• Extinguish all cigarettes, cigars, pipes and other  
sources of ignition.  
• Never refuel machine indoors because flammable  
vapors will accumulate in the area.  
• Never store the machine or fuel container inside  
where there is an open flame or spark such as a  
gas water heater, space heater, or furnace.  
• Never run an engine inside a closed area.  
• To reduce fire hazard, keep mower free of grass,  
leaves, or other debris build-up. Clean up oil or fuel  
spillage. Allow mower to cool at least 5 minutes  
before storing.  
• Before cleaning, repairing, or inspecting, make  
certain the blade and all moving parts have  
stopped. Disconnect the spark plug wire, and keep  
the wire away from the spark plug to prevent  
accidental starting.  
• Check the blade and engine mounting bolts at  
frequent intervals for proper tightness. Also,

SECTION 8: OPERATION  
Gas And Oil Fill-Up  
Oil:  
• Only use high quality detergent oil rated with API service classification SF, SG or SH. Use SAE30 oil; do not  
use 10W40 oil.  
• Fill oil sump and check the oil level following steps below.  
a. Position the mower on level ground and clean area around oil fill plug.  
b. Remove oil fill plug and dipstick. Wipe dipstick clean, insert it into oil fill hole and tighten securely.  
c. Remove dipstick and check oil level. If the oil is not upto FULL mark on the dipstick, pour recommended oil  
through the oil fill and check the level again. Install oil fill plug and dipstick, tighten securely.  
NOTE: Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, these multiviscosity oils  
will result in increased oil consumption when used above 32oF. Check the oil level more frequently to avoid possible  
engine damage from running low on oil.  
Gasoline  
WARNING: Never fill fuel tank indoors, or when engine is running or hot. Do not smoke when filling  
up the fuel tank.  
• Clean area around fuel cap. Remove cap. Use a funnel to prevent spillage.  
• Pour approximately 1.5 quarts of fresh, regular grade, unleaded gasoline slowly to the fuel tank.  
IMPORTANT: Never mix engine oil with gasoline.  
• Fill tank to 1/2” below the bottom of the filler neck. Wipe any fuel spillage. Do not fill fuel tank completely.  
Provide space for fuel expansion.  
Starting Engine  
WARNING: Be sure no one other than the operator is standing near the lawn mower while starting  
engine or operating mower.  
Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon  
monoxide, an odorless and deadly gas.  
Keep hands, feet, hair and loose clothing away from any moving parts on engine and lawn mower.  
• To prevent the unit from sliding, place your foot firmly against the tire.  
• Attach spark plug wire to spark plug. Make certain the metal cap on the end of the spark plug wire is fastened  
securely over the metal tip on the spark plug.  
• Move throttle control to FAST (rabbit) position.  
• Push primer three times. Wait about two seconds between each push. In cold weather around 55o F or  
below, prime five times. Do not prime to restart a warm engine after a short shutdown.  
• Grasp starter handle and pull rope out slowly until engine reaches the start of compression cycle (rope will  
pull slightly harder at this point). Let the rope rewind slowly. Pull rope with a rapid, continuous, full arm stroke.  
Keeping a firm grip on the starter handle, let the rope return to the starter slowly.  
Stopping Engine  
• Release blade control handle to stop the engine and the blade.  
• Disconnect spark plug wire and move away from spark plug to prevent accidental starting. Do not use the  
throttle control to stop the engine.  
Using Your Lawn Mower  
Your mower is designed to operate as a rear bagger, mulching or a side-discharge unit.  
• To convert from a mulcher to a side-discharge or a rear bagger unit, refer to instructions on page 8. Do not  
operate the mower without the mulching cover or the discharge chute properly installed and tightly secured.

• Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage lawn mower or  
engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal  
injury to the operator and others.  
For best results, do not cut wet grass because it tends to stick to the underside of the mower, preventing  
proper discharge of grass clippings, and could cause you to slip and fall. New grass, thick grass or wet grass  
may require a narrower cut. Blade speed should be adjusted to the condition of the lawn.  
• The best mowing pattern is one that allows the clippings to discharge towards the uncut part of the lawn. This  
permits recutting of the clippings to further pulverize them. When cutting high weeds, discharge towards cut  
portion, then recut at right angles to first direction.  
• For a healthy lawn, always cut off one-third or less of the total length of the grass. Lawn should be trimmed in  
fall as long as there is growth.  
• This mower is designed to run at full throttle to give you the best cut and do the most effective job of bagging  
the cut grass.  
WARNING: If you strike a foreign object, stop the engine. Remove spark plug wire from spark plug,  
thoroughly inspect the mower for any damage. Repair the damage before restarting and operating the  
mower. Extensive vibration of the mower during operation is an indication of damage. The unit should  
be promptly inspected and repaired.  
Height Adjustment  
Refer to height adjustments section of this manual on page 13 for instruction on how to adjust the cutting height and  
the handle height.  
• For best results in mowing, keep the cutting height position high until it is determined which height is best for  
your lawn.  
SECTION 9: MAINTENANCE  
WARNING: Always stop the engine and disconnect the spark plug wire before performing any  
maintenance or adjustments.  
Lubrication

Pivot Points  
• Lubricate the pivot points on the blade control handle, brake cable and the cutting height adjustment lever at  
least once a season with light oil. The blade control handle must operate freely in both directions. The cutting  
height adjustment lever should be able to move easily.  
Engine  
• Follow the engine manual instructions and recommended schedule for lubricating engine components.  
Cleaning Mower  
The underside of the mower deck should be cleaned after each use to prevent any build-up of grass clippings,  
leaves, dirt, or other debris. If this debris is allowed to accumulate, it will result in rust and corrosion.  
• Disconnect spark plug wire.  
• Drain the gasoline from the lawn mower, or place a piece of plastic under the gas cap.  
• Tip the mower so that it rests on the housing. Keep the side with the air cleaner facing up. Hold the mower  
firmly.  
• Scrape clean the underside of the deck with a suitable tool.  
• Put the mower back on its wheels on the ground. If you had put plastic under the gas cap, make sure to  
remove it now.  
WARNING: Never tip the mower more than 90 degrees and do not leave the mower tipped for any  
length of time. Oil can drain into the upper part of the engine causing a starting problem.  
Engine Maintenance  
• A list of key maintenance jobs required for good performance by the mower is given below. Follow the  
accompanying engine manual for detailed list and instructions.  
• Change engine oil after the first two operating hours and every 25 operating hours thereafter. Check the oil  
level before starting the engine every time.  
• Service foam filter in the air cleaner every 25 hours of use and replace the paper filter component every 100  
hours. You may have to service the air filter more frequently if you are operating the mower under extremely  
dusty conditions.  
• Clean the engine periodically. Remove dirt and debris with a cloth or brush. We do not recommend using a  
garden hose to clean mower unless the muffler, air filter and the carburetor are covered to keep water out.  
Water in engine can shorten engine life.  
• Clean the spark plug and reset the gap to .030” at least once a season or every 50 hours of operation. Spark  
plug replacement is recommended at the start of each season. Refer to the engine manual for correct spark  
plug type.  
• Inspect muffler periodically, and replace if necessary. Damaged mufflers or spark arresters can create a fire  
hazard. Make sure to avoid muffler and surrounding areas while the mower engine is hot because  
temperature of these areas of the engine may exceed 150o F.  
SECTION 10: SERVICE & ADJUSTMENTS  
Blade Care  
Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.  
WARNING: When removing the cutting blade for sharpening or replacement, protect hands by using  
heavy gloves or a rag to grasp the cutting blade.  
• Disconnect spark plug wire from spark plug.  
• Turn mower on its side making sure that the air filter and the carburetor are up.

WARNING: To ensure safe operation of your unit, all nuts and bolts must be checked periodically for  
correct tightness.  
To Sharpen Blade:  
• The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while operator is on  
the mower.  
• Follow the original angle of grind as a guide. Make sure that each cutting edge receives an equal amount of  
grinding to prevent an unbalanced blade.  
NOTE: An unbalanced blade will cause excessive vibration when rotating at high speeds, may cause damage to the  
mower and could break, causing personal injury.  
• Test the blade by balancing it on a round shaft screwdriver or a blade balancer. See Figure 9B.  
• If the blade is not balanced, remove metal from the heavy side until it balances evenly.  
Adjusting Handle Height  
Your mower is shipped with the handle in the higher height position. To lower the handle height, proceed as follows.  
• Remove the starter rope from the rope guide.
