Read and understand all Safety Warnings on pages 3 and 4. Improper use of this chain saw can cause severe injury or death from re, electrical shock, body contact with moving chain, or falling wood.
BEFORE OPERATING CHAIN SAW
1. Read and understand this owners manual before operating chain saw.
2. Use chain saw for cutting wood only. Do not use for cutting any non-wood items.
3. Only well-instructed adults should operate chain saw. Never allow children to operate chain saw. First-time user should obtain informed, practical instruction in addition to reading this manual. Practice cutting logs on a saw horse or cradle.
4. Use only electrical voltage noted on model plate of chain saw.
5. Use only extension cords marked for outdoor use. See page 8 for extension cord requirements.
6. Do not operate chain saw
while under the inuence of alcohol, medication, or drugs
in rain or in damp or wet areas
where highly ammable liquids or gases are present
if saw is damaged, adjusted wrong, or not fully assembled
if trigger does not turn saw on and off. Chain must stop
moving when you release trigger. Have faulty switch replaced by authorized service person.
while tired or in a hurry
while in tree or on a ladder unless trained to do so
7. Wear snug-tting clothes when operating chain saw. Do not wear loose clothing or jewelry. They can get caught in moving saw chain.
8. Wear the following safety gear when operating chain saw:
heavy-duty gloves
steel-toed safety footwear with non-skid soles
eye protection such as safety glasses, goggles, or face screen
safety hard hat
ear mufers or ear plugs
hair covering to contain long hair
face or dust mask (if working in dusty areas)
9. Before cutting, always provide the following:
clear work area
secure footing
planned retreat path from falling tree
10.Inspect tree before cutting down. Make sure there are no dead limbs or branches that may fall on you.
(wear rubber gloves if working outdoors)
This saw has a chain brake. When kickback occurs, the front hand guard is moved forward by the back of operators left hand. This stops the saw chain quickly, reducing the chance of serious injury.
Never hold the chain saw by the front hand guard.
Cause Of Kickback
Kickback may occur when nose or tip of guide bar touches an object while chain is moving. If chain cutter catches on object, a sudden reverse action will result. The guide bar will kick up and back towards operator.
Kickback may also occur when wood pinches chain at guide bar nose. A sudden reverse action will also result.
The following steps will reduce the risk of kickback:
Use both hands to grip saw while saw is running. Use rm grip. Thumbs and ngers must wrap around saw handles.
Keep all safety items in place on saw. Make sure they work properly.
Do not overreach or cut above shoulder height.
Keep solid footing and balance.
Stand slightly to left side of saw. This keeps your body
from being in direct line with chain.
Do not let guide bar nose touch anything when chain is moving (see Figure 1).

Saw Maintenance and Kickback Safety
Follow maintenance instructions in this manual. Proper cleaning of saw and chain and guide bar maintenance can reduce chances of kickback. Inspect and maintain saw after each use. This will increase the service life of your saw. Even with proper sharpening, risk of kickback can increase with each sharpening.
Note:
PUSHBACK AND PULL-IN
!
WARNING
WARNING ICON G 001
Avoid pushback and pull-in. These hazards can cause you to lose control of chain saw. Pushback or pull-in can cause severe injury.
Cause Of Pushback and Pull-In
Pushback may occur while cutting with top of guide bar. Pushback will force saw back towards you. Pull-in may occur while cutting with bottom of guide bar. Pull-in will force saw in towards wood you are cutting. These hazards can occur if chain is pinched, caught, or contacts a non-wood object.
The following steps will reduce the risk of pushback or pull-in:
Use both hands to grip saw while saw is running. Use rm grip. Thumbs and ngers must wrap around saw handles.
Do not overreach or cut above shoulder height.
Keep solid footing and balance.
Stand slightly to left side of saw. This keeps your body
from being in direct line with chain.
Have saw running at full speed before starting a cut.
When cutting, make sure spike of saw is against wood
(pull-in only). See Product Identification, page 5, to locate spike.
Never try cutting through two logs at same time. Only cut one log at a time.
Watch for shifting of log or other forces that may pinch chain.
Use extreme caution when re-entering a previous cut.
Do not twist saw when removing guide bar from undercut.
Use wedges made of plastic, wood, or light alloy (never steel
or iron) to hold cut open.
CHAIN SAW OPERATION
1. Stay alert. Use common sense while operating chain saw.
2. Keep work area clean. Cluttered areas invite injuries.
3. Be aware of extension cord while operating chain saw. Be careful not to trip over cord.
4. Keep children, animals, and bystanders away from chain saw and extension cord. Only chain saw user should be in work area.
5. Do not cut down a tree unless you are trained or have expert help.
6. If two or more persons perform bucking and felling operations at the same time, provide plenty of distance between operations. Provide distance of at least twice the height of tree being felled.
7. Secure wood you are cutting by using clamps or chocks.
8. Grip chain saw rmly with both hands. Never operate chain saw with one hand. Never use hand guard as handle.
9. Keep nger off trigger until ready to make cut.
10. Before starting chain saw, make sure chain is not touch­ing anything.

OPERATING CHAIN SAW
!
WARNING
Read and understand this owners manual before operating this saw. Make certain you read and understand all Safety Warnings. Improper use of this chain saw can cause severe injury or death from re, electrical shock, or body contact with moving chain, or falling wood.
EXTENSION CORDS
Use proper extension cord with this chain saw. Use only extension cords marked for outdoor use. Use an extension cord no less than 1.5 mm (100 feet). The cord must be marked with suffix W-A follow­ing the cord type marking.
Use an extension cord heavy enough to carry the current your saw will draw. An undersized cord will cause a voltage drop at the saw, loss of power, and overheating.
Keep cord away from cutting area. Make sure cord does not catch on branches or logs during cutting. Inspect cords often. Replace damaged cords.
The extension cord may come undone from the power cord during use. To avoid this, make a knot with the two cords as shown in Figure 7 below.

OILING CHAIN
Always check oil level before using saw. To oil chain, press oil cap. Oil will feed onto guide bar and chain. Press oil cap at least once before each cut. Check oil level often by looking at oil sight level hole. Oil sight level hole is on left side of saw, between front handle and front hand guard.
Figure 8 - Pressing Oil Cap to Oil Chain
CUTTING WITH THE CHAIN SAW
1. Connect saw to extension cord. Connect extension cord to power supply.
2. Make sure section of log to be cut is not laying on ground. This will keep chain from touching ground as it cuts through log. Touching ground with moving chain will dull chain.
3. Use both hands to grip saw. Always use left hand to grip front handle and right hand to grip rear handle. Use firm grip. Thumbs and ngers must wrap around saw handles (see Figure 9).
CHAIN BRAKE
The chain brake quickly stops the saw chain. Kickback causes the back of operators left hand to contact front hand guard (see Figure 10). When front hand guard moves forward, the saw chain stops. This reduces the chance of serious injury during kickback. When the chain brake activates, release trigger at once.
STOP
Figure 10 - The chain brake quickly stopping the saw

Log Supported On One End
1. Make rst cut on underside of log (see Figure 16). Use top of guide bar to make this cut. Cut 1/3 through diameter of log. This cut will keep section from splintering when cut.
2. Make second cut directly above rst cut. Cut down to meet rst cut. This cut will keep log from pinching guide bar and chain.
!
WARNING
If on slope, make sure log will not roll down hill. Secure log by using wooden stakes. Drive wooden stakes into ground on downhill side of log. Stand on uphill side of log while cutting. Log may roll after cutting.
Never try cutting through two logs at same time. This could increase the risk of kickback.
While cutting log, never hold log with your hand, leg, or foot.
While cutting log, never allow another person to hold log.
Turn off and unplug saw before moving from one place to another.
!
CAUTION
Seek professional help if facing conditions beyond your ability.
Bucking a log is cutting a log into sections. Make sure your footing is rm. Keep feet apart. Divide your weight evenly on both feet. Stand slightly to left of saw. This keeps your body from being in direct line with chain. When possible, raise log or section off ground. Do this by using limbs, logs, chocks, etc.
When cutting through log, maintain control by reducing cutting pressure near end of cut. Do not relax your grip on chain saw handles. Do not let moving chain touch ground. Ground will dull moving chain. After cutting through log, release trigger to turn saw off before moving saw.
