WARNING: When using an electric chain saw, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:
- CAUTION! Do not use a replacement saw chain unless:
a) It has been designated as meeting the ANSI B175 kickback performance requirements on that specific power head;
b) It has been designated as "Low-Kickback" saw chain in accordance with ANSI B175.1; or
c) It is the saw manufacturer's replacement catalogue (or equivalent) number.
Low-Kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1 when tested on the representative sample of chain saws.
-
Use the extension cord to be a type acceptable for outdoor use, for example – SJTW, and the size should be 14AWG or larger. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Make sure the extension cord is in good condition before using; and keep the cord away from the cutting area and to position cord so that it will not be caught on branches, and the like, during cutting.

FOR ALL DOuBLE-INSuLAtED CHAIN SAwS
1) Replacement Parts
When servicing use only identical replacement parts.
2) Polarized Plugs
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
FOR ALL CHAIN SAwS
1) Keep work area clean.
Cluttered areas invite injuries.
Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
2) Consider work area environment.
Use extreme caution when cutting small size brush and saplings because the slender material may catch the saw chain
and be whipped toward you or pull you off balance.
Do not operate a chain saw in a tree unless specifically trained to do so.
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.
Don't expose chain saw to rain.
Don't use chain saw in damp or wet locations.
Do not use chain saw in presence of flammable liquids or gases.
3) Protect yourself against electric shock
Prevent body contact with grounded surfaces. For example: metal pipes, wire fences.
4) Keep children away
Do not let visitors contact the chain saw or extension cord.
All visitors should be kept away from work area.
5) Store idle chain saw
When not in use, chain saws should be stored in a dry, and high or locked-up place – out of the reach of children.
When storing saw, use a scabbard or carrying case.
6) Don't force chain saw
It will do the job better and safer at the rate for which it was intended.
7) Use right tool
Cut wood only.
Don't use chain saw for purpose not intended – for example – Don't use chain saw for cutting plastic, masonry, non-wood building materials.
8) Dress properly
Do not wear loose clothing or jewelry.
They can get caught in moving parts.
Rubber gloves and non-skid footwear are recommended when working outdoors.
Wear protective hair covering to contain long hair.
9) Use safety glasses/safety visor
Also use safety footwear; snug fitting clothing; protective gloves; hearing and head protection.
10) Carrying saw
Carry the chain saw by the front handle
with the saw stopped, finger off the switch, the guide bar and saw chain to the rear.
11) Maintain Chain saw with care
Inspect chain saw cords periodically and if damaged, have repaired by authorized service facility.
Keep cord clear of the chain and operator at all times. Never carry saw by the cord or pull it to disconnect from receptacle. Keep cord from oil and sharp edges.
Inspect extension cords periodically and replace if damaged.
Keep tools sharp and clean for better and safer performance.
Follow instructions for lubrication and changing accessories.
Keep handles dry, clean, and free from oil and grease.
12) Disconnect chain saw
Disconnect chain saw when not in use, before servicing, and when changing accessories and attachments, such as saw chain and guard.
13) Outdoor use extension cords
Use only extension cords intended for use outdoors and so marked.
14) Stay alert
Watch what you are doing. Use common sense. Do not operate chain saw when you are tired.
Keep all parts of the body away from the saw chain when the motor is operating.
Before you start the saw, make sure the saw chain is not contacting anything.
15) Check damaged parts
Before further use of the chain saw, a guard or other part that is 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 center unless otherwise indicated elsewhere in this instruction manual.
Have defective switches replaced by authorized service center.
Do not use chain saw if the switch does not turn it on and off.
Do not operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the trigger is released.
16) Guard against kickback

WARNING: KICKBACK may occur
When the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious injury to user.
The following precautions should be followed to minimize kickback.
(1) Grip saw firmly.
Hold the chain saw firmly with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw handles.
(2) Do not over reach.
(3) Keep proper footing and balance at all times.
(4) Don't let the nose of the guide bar contact a log, branch, ground or other obstruction.
(5) Don't cut above shoulder height.
(6) Use devices such as low kickback chain, guide bar nose guards, chain brakes and special guide bars that reduce the risks associated with kickback.
(7) Only use replacement bars and chains specified by the manufacturer or the equivalent.
17) Power supply
Connect chain saw to correct voltage, that is, be sure that the voltage supplied is the same as that specified on the nameplate of the tool.
18) WARNING: To minimize the risk
⚠️ of eye injury, always use eye protection!
SAvE tHESE INStRuCtIONS
General safety precautions for chain saw users
- Fatigue causes carelessness. Be more cautious before rest periods and towards the end of your shift.
- Personal protective clothing required by your safety organizations, government regulations, or your employer should be used. At all times when using a chain saw, snug-fitting clothing, protective eyewear, safety footwear, and hand, leg, and hearing protection should be worn.
NOTE: personal protective clothing should meet the requirements of applicable standards.
-
When felling, keep at least 2 tree lengths away from your fellow workers.
-
Plan your work, ensuring an obstacle-free work area and, in the case of felling, at least one escape path from the falling tree.
-
Follow the instructions in your operator's manual for starting the chain saw and control the chain saw with a firm grip on both handles when it is in operation. Keep handles dry, clean, and free of oil.
-
When transporting your chain saw, use the appropriate transportation covers, which should be available for the guide bar and saw chain.
-
Do not attempt a pruning or limbing operation in a standing tree unless specifically trained to do so.
-
Guard against kickback. Kickback is the upward motion of the guide bar that occurs when the saw chain, at the nose of the guide bar, contacts an object. Kickback can lead to dangerous loss of control of the chain saw.
-
A chain saw is intended for two-handed use. Serious injury to the operator, helpers, and/or bystanders can result from one-handed operation.
-
See symbol definitions.
-
Keep other persons or animals a safe distance away from a running chain saw or the area where a tree is being felled.
-
Use extreme caution when cutting small brush and saplings because slender material can catch the saw chain and be whipped toward you.
-
When cutting a limb that is under tension or compression, be alert for springback.
-
This electrically powered saw is classified by CSA as a Class 2C saw. It is intended for infrequent use by homeowners, cottagers, and campers, and for such general applications as clearing, pruning, cutting firewood, etc. it is not intended for prolonged use.

ASSEMBLY
WARNING! Do not connect the chain saw to mains before it is completely assembled. Always use gloves when handling the chain.
CHAIN AND CHAIN BAR ASSEMBLY
- Unpack all parts carefully.
- Place the chain saw on any suitable flat surface.
- Use only genuine WORX chains designed for chainbar.
- Slide the chain (8) in the slot around the chain bar (7). Ensure chain is in correct running direction by comparing with chain symbol (14). Ensure the chain tensioning catch (18) is facing outwards. (See Fig. A2)
- Fit the chain onto the drive sprocket (13) and guide the chain bar (7), so that the fastening bolt (17) and the two guide fins (15) fit into the keyway of the chain bar(7). (See Fig. B)
- Check if all parts are seated properly and hold chain and chain bar in a level position. (See Fig. C1)
- Fit cover plate, ensure that the chain catch bolt (20) fits into the groove of the cover plate(11). (See Fig. C2)
- Screw on the cover plate (11) with the locking knob (10). (See Fig. D) The chain is not yet tensioned. Tensioning the chain applies as described under "Tensioning chain".
TENSIONING CHAIN
New saw chains will stretch. Check chain tension frequently when first used and tighten when chain becomes loose around chain bar.

WARNING: Unplug chain saw from power source before adjusting saw a tension.

WARNING: Cutting edges on chain are sharp. Use protective gloves in handling chain.

WARNING: Maintain proper chain tension always. A loose chain will ease the risk of kickback. A loose may jump out of guide bar groove. May injure operator and damage
chain. A loose chain will cause chain, chain bar, and sprocket to wear rapidly.
- Place the chain saw on any suitable flat surface.
- Turn the locking knob/ chain tensioning knob (10) clockwise until the locking knob is screwed tightly. The correct chain tension will be reached automatically.
The ratchet mechanism(a)E2 prevents the chain tension from loosening.(See Fig. E2) - The correct chain tension is reached when the chain (8) can be raised approx. 3 - 6 mm from the chain bar in the centre. This should be done by using one hand to raise the chain against the weight of the machine. (See Fig. E1)
- When the chain looses, unscrew the locking knob/ chain tensioning knob absolutely and then Screw on the cover plate with the locking knob tightly again.
LUBRICATION
IMPORTANT: the chain saw is not supplied filled with oil. It is essential to fill with oil before use. Never operate the chain saw without chain oil or at an empty oil tank level, as this will result in extensive damage to the product.
Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain is automatically oiled during operation via oil outlet.
Filling oil tank:
- Set chain saw on any suitable surface with oil filler cap facing upward.
- Clean area around the oil filler cap with cloth unscrew cap.
- Add WORX chain saw oil until reservoir is full.
- Avoid dirt or debris entering oil tank, refit oil filler cap (4) and tighten.
IMPORTANT: To allow venting of the oil reservoir, small breather channels are provided between the oil filler cap and the strainer, to prevent leakage ensure machine is left in a horizontal position (oil filler cap (4) uppermost) when not in use.
It is important to use only the recommended oil to avoid damage to the chain saw. Never use recycled/old oil. Use of non approved oil will invalidate the warranty.
Checking the automatic oiler
Proper functioning of the automatic oiler can be checked by running the chain saw and pointing the tip of the chain bar towards a piece of cardboard or paper on the ground. Caution: Do not touch the ground with the chain. Ensure safety clearance of 20 cm. If an increasing oil pattern develops, the automatic oiler is operating fine. If there is no oil pattern, despite a full oil reservoir, contact WORX customer service agent or approved service agent.
OPERATION
1. SWITCHING ON AND OFF (See Fig. F) ATTENTION! Check the voltage and current supply: The voltage and current supply must comply with the ratings on the type plate.
For switching on the machine, press the lock-off button, then fully press the on/off switch and hold in this position. The lock-off button can now be released.
For switching off, release the on/off switch. Do not stop chain saw after sawing by activating the front hand guard (kickback brake).
2. KICKBACK BRAKE (See Fig. G1)
The kickback brake is a safety mechanism activated through the front hand guard (5), when kickback occurs. Chain stops immediately.
The following function check should be carried out at regular intervals. Pull front hand guard (5) forwards (position②and start the chain saw. The chain must not start. To deactivate the kickback brake, release On/Off switch (2) and push hand guard (5) backwards (position ①
CUTTING
Is the oil reservoir filled? Check oil level gauge
(19) prior to starting and regularly during operation. Refill oil when oil level is low. The oil tank filling will last approx. 16 minutes, depending on sawing intensity and stops. (Fig. G2)
Check new replaced chain tension approx. every 10 minutes during operation.
- Connect saw to extension cord. Connect extension cord to power supply.
- 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.
- 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 fingers must wrap around saw handles.(See Fig.H)
- Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet.
- When ready to make a cut, push the lock-off button completely forward with the right thumb and squeeze the trigger. This will turn saw on. Releasing trigger will turn saw off. Make sure saw is running at full speed before starting a cut.
- When starting a cut, place moving chain against wood. Hold saw firmly in place to avoid possible bouncing or skating (sideways movement) of saw.
- Guide saw using light pressure. Do not force saw. The motor will overload and can burn out. It will do the job better and safer at the rate for which it was intended.
- Remove saw from a cut with saw running at full speed. Stop saw by releasing trigger. Make sure chain has stopped before setting saw down.
- Practice until you can maintain a steady, even cutting rate.
KICKBACK SAFETY DEVICES ON THIS SAW
This saw has a low-kickback chain and reduced kickback chain bar. Both items reduce the chance of kickback. Kickback can still occur with this saw.
The following steps will reduce the risk of kickback.
- Use both hands to grip saw while saw is running. Use firm grip. Thumbs and fingers 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 at all times.
- 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.
- Never try cutting through two logs at same time. Only cut one log at a time.
- Do not bury guide bar nose or try plunge cut (boring into wood using guide bar nose).
- Watch for shifting of wood or other forces that may pinch chain.
- Use extreme caution when reentering a previous cut.
- Use low-kickback chain and guide bar supplied with this chain saw.
- Never use dull or loose chain. Keep chain sharp with proper tension.
GENERAL BEHAVIOR
Use the chain saw only with secure footing. Hold the chain saw at the right-hand side of your body. (See Fig. I)
The chain must be running at full speed before it makes contact with the wood. Use the metal gripping teeth to secure the saw onto the wood before starting to cut. Use the gripping teeth as a leverage point "a" while cutting. (See Fig. J)
Do not operate the chain saw with arms fully extended or attempt to saw areas which are difficult to reach, or on a ladder. Never use the chain saw above shoulder height.
(See Fig. K)
CUTTING WOOD UNDER TENSION (See Fig. L)

WARNING: When cutting limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released,
limb could spring back and strike operator causing severe injury or death.
When sawing logs supported on both ends, start the cut from above(Y) about 1/3 of the diameter into the log and then finish the cut (Z) from below, in order to avoid contact of the chain saw with the ground. When sawing logs supported on only one end, start the cut from below (Y) about 1/3 of the diameter into the log and finish the cut from above (Z) in order to avoid log splitting or jamming of the chain saw.
FELLING TREES (See Fig. M)
Always wear hard hat to protect head against falling branches.
The chain saw can only be used to fell trees smaller in diameter than the length of the chain bar.
① Secure work area. Ensure no persons or animals are in the vicinity of the falling tree.
Never attempt to free a jammed saw with the motor running. Use wooden wedges to free chain and chain bar.
When cutting and felling operations are being performed by two or more persons, at the same time, the felling operations should be separated from the cutting 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 company should be notified immediately.
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.
② An escape path should be planned and cleared as necessary before cuts are started. The escape path should extend back and diagonally to the rear of the expected line of fall.
③ Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails
staples, and wire from the tree.
Notching undercut: Make the notch (x-w)1/3 the diameter of the tree, perpendicular to the direction of falls as make the lower horizontal notching cut first. This will help to avoid pinching either the saw chain or the guide bar when the second notch is being made.
WARNING: Do not cut all the way through tree. Leave about two inches of tree diameter uncut directly behind felling notch (See Figure M). This uncut portion acts as a hinge(Y). The hinge helps keep tree from twisting and falling in wrong direction.
As the felling gets close to the hinge the tree should begin to fall. If there is any chance that the tree may not fall in desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic, or aluminum to open the cut and drop the tree along the desired line of fall.
When the tree begins to fall remove the chain saw from the cutting, stop the motor, put the chain saw down, and then use the retreat path planned. Be alert for overhead limbs falling and watch your footing.
To complete the felling operation, drive a wedge (Z) into the horizontal cut.
LIMBING A TREE (See Fig. N)
Limbing is removing the branches from a fallen tree. When limbing leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut as illustrated. Branches under tension should be cut from the bottom up to avoid binding the chain saw.
BUCKING A LOG (See Fig. 0)
Bucking is cutting a log into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs or chocks. Follow the simple directions for easy cutting.
When the log is supported along its entire as illustrated, it is cut from the top (overbuck).
When the log is supported on one end,
as illustrated, cut 1/3 the diameter from the underside (underbuck). Then make the finished cut by overbucking to meet the first cut. (See Fig. P)
When the log is supported on both ends, as illustrated, cut 2/3 the diameter from the top overbuck. Then make the finished cut by underbucking the lower 1/3 to meet the first cut. (See Fig. Q)

WARNING: (See Fig. R)
- 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.
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.
NOTE: Even with proper sharpening, risk of kickback can increase with each sharpening.

Replacing Saw Chain/chain bar
Replace chain when cutters are too worn to sharpen or when chain breaks. Only use replacement chain noted in this manual.
Always include new drive sprocket when replacing chain. This will maintain proper driving of chain.
Inspect guide bar before sharpening chain. A worn or damaged guide bar is unsafe. A worn or damaged guide bar will damage chain. It will also make cutting harder.
Fit the tensioning catch into the new bar by tightening the screw clockwise. The catch
protrude (b) must be fitted into the bar hole. (See fig. S)
SHARPENING SAW CHAIN

WARNING: Unplug chain saw from power source before servicing.
Severe injury or death could occur from electrical shock or body contact with moving chain.

WARNING: Cutting edges on chain are sharp. Use protective gloves in handling chain.
Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, guide bar, chain, and motor wear. If you must force chain into wood and cutting creates only sawdust with few large chips, chain is dull.
