CS3814, CS3816, CS4116 Chainsaws  
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 thesaw 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.

The felling notch is the first cut when felling a  
tree. The notch will act as a hinge and will direct  
the tree to fall in the desired direction.

to the desired felling direction.  
2) Make a downward cut at 45-degress to a depth of about 1/5  
to 1/4 of the overall diameter of the tree.  
3) Finish the notch by making a horizontal cut perpendicular to  
the desired felling direction.

3) Drive plastic or wooden wedges into the felling cut to control  
the fall.  
4) As the tree begins to fall, alert others and immediately  
evacuate the area around the tree.  
caution  
do not cut through the hinge. cutting  
through the hinge increases the risk of  
losing control of the felling direction.  
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.  
Tobuckapillowedorsupportedlog,alwaysmakearelievingcut  
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.  
“Buckingis 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 anInertial 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.

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.  
Figure 1  
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.

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  
elementbylightlytappingacornerofthelteragainstahardsurface.  
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.

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.
