•
•
•
•
•
Always hold the chainsaw firmly with both hands when the
engine is running. Use a firm grip with thumb and fingers
encircling the chainsaw handles.
• Do not over-reach or cut above shoulder height.
• Always maintain a sharp and clean saw chain. Follow
manufacturer’s sharpening and maintenance instructions for
the saw chain.
When carrying from one place to another, always stop the
engine and hold the saw with the guide bar and saw chain
behind you and the muffler away from your body.
• Only use replacement bars and chains specified by the
manufacturer or an appropriate equivalent.
Alwaysinspectthechainsawforworn, loose, ordamagedparts.
Never operate a chainsaw that has been damaged, improperly
adjusted, or is not completely and securely assembled.
sawing
• This saw is provided for the sole intended purpose of cutting
wood. Do not cut other materials with this saw.
Use extreme caution when cutting small brush and saplings.
Thinner material may be caught by the chain and could whip
back toward you or pull you off balance.
• Do not attach other tools or accessories to the output shaft of
the power unit. Doing so will void the manufacturer’s warranty.
• Do not apply excessive pressure to force the saw through the
cut. Run the engine at full throttle and apply only light pressure.
When cutting limbs under tension, stay alert for“spring back”
so you are not struck when the tension in the wood fibers is
released.
• Always maintain a firm footing.
•
•
Always shut off the engine before setting the chainsaw down.
Keepthehandlesdry, clean, andfreeoflubricants, oilsandfuel.
• Never cut from a stepladder or while in a tree.
• Never use the guide bar as a means to lift, pry, move or split
objects.
kickback
• Never mount the chainsaw on a fixed stand.
Kickback may occur when the guide bar nose or
tip comes into contact with a foreign object, or
when the“saw kerf”(gap in the wood being cut)
closes in on the bar and pinches the saw chain.
• If the guide bar and saw chain become pinched in a cut, do not
race the engine or pull the saw out of the cut by force. Use a
wedge or lever to open the cut and pull the saw free.
felling a tree
Tip contact in some cases may cause a lightning-
fast reverse action, kicking the guide bar up and
back toward the operator.
Felling refers to the process of cutting down a standing tree.
Numerous factors must be taken into consideration when
felling a tree. First consider the environmental factors which will
determine the felling direction:
Pinching the saw chain along the top of the
guide bar may push the guide bar and the saw
unit backward toward the operator.
• Wind is a major determining factor of felling direction.
• Locationandnumberofheavybranchesandtheleanofthetree.
• Ease of bucking and clean-up after felling
Either of these reactions may cause the operator
to lose control of the chainsaw, which could
result in serious personal injury or death.
• Nearby standing timber in which the felled tree could hang up.
Do not rely exclusively on the safety devises
built into your saw. As a chainsaw user, it is
your responsibility to understand the inherent
dangers of chainsaw use and the precautions
necessary to minimize those dangers.
• Location of power, telephone and data utilities, buildings,
roads, bodies of water, property lines, etc.
• Wood structure and condition (i.e. rotten heartwood or core).
• Keep all bystanders at least 2-1/2 tree lengths away from the
base of the tree to be cut. This area is considered a danger zone
and must be avoided before and during the felling operation.
Precautions to Avoid Kickback:
• Always grip the chainsaw firmly with both
hands; the right hand on the rear handle, and
the left hand on the forward grip.
retreat path
Plan two (2) retreat paths away from the felling direction of the
tree. Do not retreat in the opposite direction from the falling tree.
Instead, retreat at a 45-degree angle to either side.
• Make certain the area in which you are cutting
is free from obstructions. Do not let the guide
bar nose come into contact with a log, branch, rock or other
objects while cutting. Such contact could result in a kickback.
• Clear the retreat paths of all obstacles.
• Always make cuts at high engine speeds.
• Place all excess tools and equipment a safe distance from the
tree, but not in the retreat paths.

limbing a felled tree
“Limbing”refers to removing the limbs from a fallen tree. There is an
extremely high danger of kickback during the limbing operation. Do
notworkwiththenoseoftheguidebar, asthiscouldcauseakickback.
Use extreme caution and avoid contact between the nose of the bar
and the log or other limbs. Do not stand on the log while limbing it as
the log may roll as limbs are removed and the center of gravity shifts.
•

through about 1/3 the diameter of the log from the compressed
side. Finish with a bucking cut from the tension side of the log.
Tip: When cutting firewood, make sure you know the
optimum length of the finished firewood ahead of time. Use
the guide bar as an approximate length gauge.
Start limbing by removing limbs from the top side of the log,
leaving limbs on the bottom to support the log up off the ground.
Limbs under tension may pinch the guide bar and saw chain.
Shut off the engine and lift the limb to remove the bar safely.
pruning
Bucking a log
Pruning is removing limbs from a standing tree, often for
purposes of maintaining a tree’s health or aesthetics. Always
work with a firm footing. Never cut from a stepladder. do not
over reach. do not cut above shoulder height.
“Bucking”is the cross-cut operation of cutting a log into usable
sections. Do not stand on the log while bucking as it may roll.
When bucking on a slope, stand uphill of the log in case it begins
to roll unexpectedly. Cut only one log at a time.
1) Begin pruning by making a relief cut about 3 inches away from the
trunkofthetreetoadepthofabout1/3thediameterofthebranch.
•
When bucking small logs, place them in a“V”shaped bucking
horse to keep them at a working level. Never allow a bystander
to hold the log. Never hold the log with your leg or foot.
2) Complete the cut from above, just inside of the initial relief cut.
3) Finish pruning by making a smooth even cut nearly flush to the
trunk. Itisrecommendedtoonlyprunetreeswhiletheyaredormant

2. throttle interlock: This saw is equipped with a throttle
interlock designed to prevent accidental engagement of
the throttle control. The throttle interlock is disengaged by
depressing the red tab on top of the rear handle. This is usually
accomplished when the user grasps the rear handle to operate
the saw.
safety features
This saw is equipped with certain safety features and devices
to protect the user from harm in the event the saw reacts
unexpectedly to external forces:
1. chainBrake: The saw is equipped with a chain brake designed
to stop the chain instantaneously upon activation. The chain
brake can be activated in one of two ways:
3. chain catcher: Each saw is equipped with a chain catcher
beneath the clutch cover. If the chain is ever thrown from the
guide bar, or if the chain breaks, the chain catcher is designed
to capture the chain and prevent it from whipping back toward
the operator.
•
The forward hand guard doubles as an activation lever for
the hand brake. It can be activated manually, or it may be
activated by the user’s arm if a kickback occurs.
•
The saw is also equipped with an“Inertial Chain Break.” The
same mechanism as above is activated by the inertial force
created when a counterweight under the forward hand
guard accelerates toward the bar nose during a kickback.
NOTE: Inspect the chain catcher before each use. Replace if
missing or badly damaged.
4. kickback reductionguide Bar and saw chain:This saw has
been equipped with a Double Guard® 91 guide bar and 91VG
S-Series Low Kickback saw chain by Oregon®. The features of
this bar and chain combination are design to reduce the risk
of kickback. To maintain adequate kickback prevention, only
use these components when replacing guide bar or saw chain.
(Refer to the Maintenance section of this manual for full details)
•
Proper cleaning and care of the chain brake system are
required to ensure reliable operation in the field. You should
also check your chain brake for proper operation regularly.
To check your chain brake:
Manually activate the chain brake by pushing the forward
hand guard toward the bar nose. There will be an audible
click when the chain brake engages. If there is no audible
click, the brake may already be engaged. Pull back on the
forward hand guard to deactivate the brake. An audible
click should be heard when the brake disengages. If there
is still no audible click, the brake is not functioning properly.
Remove the clutch cover, clean and reassemble, and re-test.
If no audible click is heard, contact customer service for
further assistance.
With the saw’s engine shut off and the brake disengaged,
firmly grasp both handles and hold the saw over a log
or low stump. Swing the bar nose sharply down until it
makes contact. This should create enough inertial force
to automatically activate the chain brake. When the brake
engages, an audible click should be heard. If no audible click
is heard, the brake is not functioning properly. Remove the
clutch cover, clean and reassemble, and re-test. If no audible
click is heard, contact customer service for further assistance.

1. Carefully remove all items from the packaging. Place the
power unit on a flat, stable work surface with the muffler
facing to your right.
2. Pull back (toward the forward handle) on the brake lever to
ensure that the chain brake is disengaged.

3. Using the “Scwrench” multi-tool, loosen and remove the bar
nuts securing the clutch cover to the power unit. Set the clutch
cover aside. Tip: If working in the field, place the bar nuts in
the clutch cover to keep from losing them in grass or foliage.
onto the bar studs. Only finger tighten the bar nuts at this step.
10. Locate the tension screw on the front of the power unit next
to the guide bar. Use the Scwrench to turn the tension screw
clockwise. This will take the slack out of the saw chain. When
properly tensioned, two conditions must be met:
4. Remove the plastic shipping spacer from the bar studs. The
purpose of this spacer is to keep the clutch cover in the correct
position when the guide bar is not installed on the power unit.
see figure 1.
• The chain should not hang or droop away from the guide
bar.
5. Install the guide bar on the bar studs, and slide the bar back
until it comes into contact with the drive sprocket.
• You should be able to pull the chain slightly away from
the guide bar, but not so far as to be able to disengage the
drive links from the groove around the perimeter of the bar.
6. Carefully remove the saw chain from its package. Stretch the
chain out into a long horizontal loop. the cutting teeth on
the top length of chain should face away from the power
unit. The cutting teeth on the bottom length of the chain
should face toward the power unit. Protective gloves should
be used when handling the chain.
11. Pull up on the guide bar’s nose and use the Scwrench to tighten
the bar nuts. Check that the chain spins freely around the bar
by hand. If there is resistance, the chain may be too tight.
12. Place the bar scabbard over the guide bar and saw chain. This
guard will help to protect the user from the sharp cutting
teeth as well as help keep the cutting teeth sharp when the
saw is not in use.
7. Wrap the chain around the drive sprocket first, and lay the
drive links of the chain into the groove along the outer
perimeter of the guide bar. Lay the chain over the nose (tip)
of the guide bar.
13. Check the tension of the saw chain frequently during use,
especially during the first two hours of use on a new chain.
Re-tension as needed.
8. Slide the bar forward until the bar mates with the tensioning
tab. Make sure that the drive links of the chain are seated
within the groove around the perimeter of the bar. If the bar
will not slide forward far enough, use the screwdriver end of
the Scwrench to turn the tension screw counter-clockwise.
The tension screw is located on the front of the power unit,
next to the guide bar.
14. Always release the tension in the chain after finishing work
and before the saw chain and guide bar cool completely. As
the saw chain heats up during operation, it will expand and
stretch, requiring re-tensioning on occasion. As the saw cools
down the saw chain will shrink, and if left tensioned, could
cause severe and permanent damage to the guide bar or the
power unit’s drive components.
9. Replace the clutch cover over the bar, and turn the bar nuts

Bar and chain oil
engine maintenance
The saw is equipped with an adjustable chain oiler. The oil
pump, driven by the drive sprocket, will only pump oil when the
engine is running at high enough speeds to engage the clutch
and rotate the chain. Furthermore, the flow of oil is adjustable to
accommodate variations in chain oil due to temperature.
cooling fins
Cooling fins, air inlets, and linkages must be free from any debris
before each use.
air filter
Never run engine without air cleaner properly installed. Added wear
and engine failure may occur if air cleaner is not installed on engine.
To adjust the oil pump, insert a screwdriver in the small notch
beneath the clutch and drive sprocket. To increase the flow
of oil, turn the screwdriver counter-clockwise. To decrease
the flow of oil, turn the screwdriver clockwise. For optimum
performance, use a higher rate of flow with thicker oil or in
colder temperatures, and a lower rate of flow with thinner oil or
in warmer temperatures.
Service air cleaner every 3 months or after 20 hours of operation.
Clean filter daily in extremely dusty conditions.
steps for cleaning air filter
1. Remove the air cleaner cover by turning the thumb screw on top
of the power unit counter-clockwise and lifting the cover off.
The guide bar and saw chain need to be well lubricated during
operation to prevent permanent damage from friction and heat.
Be sure to check the oil supply to the bar and chain before use.
2. To remove the filter, lift the filter element off of the threaded stud.
3. Larger surface dust and dirt particles can be removed from the filter
elementbylightlytappingacornerofthefilteragainstahardsurface.
1. After starting the engine, hold the saw up with the chain
suspended in front of or above a test surface.
4. To clean finer dust trapped in the mesh screens, split the filter
by inserting a flat screwdriver between the dogs on one corner
of the filter element and twisting.
2. Run the engine at about half throttle.
3. Oil should be flung off of the rotating chain onto the test
surface.
5. Using an air compressor at a low pressure or a store-bought
compressed air duster, blow air through the mesh from the inside.
If the saw chain seems dry, but there is some oil present on the
bar or test surface, the oil pump may be set too low. Increase
the setting by turning the adjustment screw counter-clockwise.
If the saw chain and guide bar are dry and there is no oil on the
test surface, the oiler port and guide bar may need cleaning.
Remove the clutch cover, bar, and chain, and clean under the
clutch cover with a brush and clean the guide bar with a wire or
small screwdriver.
6. Press the two filter halves back together by squeezing around the
rim. Do not place pressure on the mesh or a puncture could occur.
7. Place the filter back over the threaded rod, making sure to seat
the filter on the O-ring on the carburetor.
8. Place the air cleaner cover back on the saw body and turn the
thumb screw clockwise until finger tight.
Reassemble and retest for oil presence. If no oil is present after
adjusting the oiler setting and cleaning the oiler port, the oil
pump may not be functioning. Discontinue use of the unit and
contact your local authorized service center or customer service
for assistance.
spark plug
The recommended spark plug is a NGK BPM6A, Champion CJ7Y,
or Torch L7TC.
steps for removing the spark plug
1. Remove the air cleaner cover by turning the thumb screw on top
of the power unit counter-clockwise and lifting the cover off.
In compliance with EPA regulations, any adjustments to the
carburetor must be made by an authorized service center.
An authorized service center is capable of troubleshooting
carburetor problems, adjusting carburetors to perform correctly,
and adjusting carburetors to compensate for altitude.
2. Disconnect the spark plug cap and clean any debris from
around the spark plug area.
3. Remove spark plug using the“Scwrench”multi-tool. Replace if
any of the following occur; pitted electrodes, burned electrodes,
cracked porcelain, or deposits around the electrodes.
IMPORTANT NOTE: Carburetor is set at factory. Further
adjustment must be performed by an authorized service center.
Contact customer service for a list of authorized service centers.
4. After analysis, seat spark plug and turn by hand until finger
tight.

sharpening saw chain cutters (teeth)
installing spark plug
The saw chain included with this saw is a 91VG Chamfer Chisel™ or
91P Chamfer Chisel™ and requires a 5/32 inch round file (included
in the original packaging).
1. Reinstall original spark plug, tighten additional 1/2 turn.
2. Installing new spark plug, adjust spark plug gap to .025”
(0,635mm) and tighten additional 1/8 – 1/4 turn.
When to have your saw chain sharpened:
• Sawdust becomes powder-like
NOTE: Loose spark plug may overheat and damage engine.
Over tightened spark plug may damage threads in the
cylinder head.
• You need to force the saw into the cut
carBuretor
• The saw tends to cut through at an angle instead of making a
straight cut
Never tamper with the factory setting of the carburetor.
• Vibration increases
• Fuel consumption increases
saW chain tension maintenance
Keeping the saw chain at the proper tension is necessary for
safe operation and will help prolong the life of the saw chain
and the guide bar.
Always inspect your saw chain prior to sharpening. Check for
the following:
•
•
•
Bent or burred drive links
Broken cutters or tie-straps
Loose rivets or broken rivet heads
1. Shut the power unit off and allow the saw to cool.
2. The saw chain should not hang down from the bottom edge
of the guide bar.
If broken components are found, discard the chain immediately.
To properly sharpen you saw chain:
3. Wearing protective gloves, hold the guide bar with one hand
and pinch the chain with the free hand.
1. Be sure to have the correct size file and file guide.
4. Pull down on the chain. It should pull away from the bar, but
the drive links should not disengage the groove around the
perimeter of the guide bar.
2. When hand filing it’s important that 1/5, or 20 percent, of the
file’s diameter is always held above the cutter’s top plate.
3. Keep the correct top-plate filing angle line on your file guide
parallel with the chain.
5. Add or remove tension as needed.
6. Hold up on the guide bar nose and tighten the bar nuts with
the Scwrench.
4. Sharpen all cutters on one side of the chain first. Sharpen
by filing from the inside of each cutter to the outside. After
sharpening the first side, turn the saw around and repeat the
process for cutters on the other side of the chain.
Add tension at the beginning of every work session.
Check tension at every re-fueling.
5. If the chrome surface of the top or side plates is damaged, file
back until such damage is removed.
Remove tension at the end of every work session.
6. Keep all cutters at an equal length. Begin filing on the cutter
with the most damage, and file all subsequent cutters to the
same length.
saW chain maintenance
Keeping the saw chain sharp is a critical component to operating
a chainsaw. A dull saw chain will drastically reduce cutting
efficiency and can pose certain safety hazards.
7. DO NOT alter or file the tops of bumper tie strap links (between
each cutter) on the 91VG chain.
•
Avoid unintentionally striking foreign objects. This can cause
a kickback, but will also reduce the sharpness or permanently
damage the saw chain.
•
•
•
Avoid cutting wood that has been drug on the ground. Sand,
dirt, and mud stuck to the log will dull the saw chain.
Avoid cutting wood that may contain metal such as nails,
staples, or wire.
Avoid cutting all the way through when bucking a log. This
could allow the chain to come into contact with the soil below,
dulling the saw chain.

metal object as this will damage the file.
At Earthquake, we build quality and durability into the design
of our products; but no amount of careful design by us, and
careful maintenance by you, can guarantee a repair-free life
for your Earthquake Chainsaw. Most repairs will be minor, and
easily fixed by following the suggestions in the troubleshooting
guide in this section.
It is also important to maintain the depth gauge setting
throughout the lifespan of the saw chain. 91VG and 91P chains
use a depth setting of .025”. This setting should be checked and
corrected every third or fourth time the saw chain is sharpened.
1. Place the correct depth-gauge tool over the chain, with one
depth gauge protruding through the slot in the tool.
The guide will help you pinpoint the causes of common problems
and identify remedies.
2. If the depth gauge extends above the slot, use a flat file to bring
the depth gauge flush with the top of the tool. Use only the
push stroke of the file. Pulling the file will damage the file.
For more complicated repairs, you may want to rely on your
retailer, an authorized service center or Earthquake. A parts
breakdown is located toward the end of this manual.
3. Make sure to round over the leading edge of the depth
gauge to prevent kickbacks and tie strap breakage.
