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:

1. 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.

2. 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.

3. NOMENCLATUER (See Fig A1) a) Bucking – The process of cross cutting a

felled tree or log into lengths. b) Chain Brake – A device used to stop the

chain saw. c) Chain saw power head – A chain saw

without the saw chain and guide bar. d) Clutch – A mechanism for connecting and

disconnecting a driven member to and

from a rotating source of power. e) Drive Sprocket or Sprocket – The toothed

part that drives the saw chain. f) Felling – The process of cutting down a

tree.

g) Felling Back Cut – The ﬁnal cut in a tree

felling operation made on the opposite side of the tree from the notching undercut.

h) Front Handle (6)– The support handle

located at or toward the front of the chain saw.

i) Hand guard (5)– A structural barrier

between the front handle of a chain saw and the guide bar, typically located close to the hand position on the front handle and sometimes employed as an activating lever for a chain brake.

j) Chain bar(7) – A solid railed structure that

supports and guides the saw chain.

k) Kickback – The backward or upward

motion, or both of the guide bar occurring when the saw chain near the nose of the top area of the guide bar contacts any object such as a log or branch, or when the wood closed in the pinches the saw chain in the cut.

l) Kickback, Pinch – The rapid pushback of

the saw which can occur when the wood closes in and pinches the moving saw chain in the cut along the top of the guide bar.

m) Kickback, Rotational – The rapid upward

and backward motion of the saw which can occur when the moving saw chain near the upper portion of the tip of the guide bar contacts an object, such as a log or branch.

teeth, that cut the wood, and that is driven

by the motor and is supported by the guide

bar. v) Gripping teeth (Spike)(9) – The pointed

tooth or teeth for use when felling or

bucking to pivot the saw and maintain

position while sawing. w) On/Off switch (2)– A device that when

operated will complete or interrupt an

electrical power circuit to the motor of the

chain saw. x) Switch Linkage – The mechanism that

transmits motion from a trigger to the

switch. y) Lock-off button(3)– A movable stop that

prevents the unintentional operation of the

switch until manually actuated.

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

1110

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

The following precautions should be

17) Power supply Connect chain saw to correct voltage, that

18) WARNING: To minimize the risk

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.

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,

SAVE THESE INSTRUCTIONS

General safety precautions for chain saw users

1. Fatigue causes carelessness. Be more cautious before rest periods and towards the end of your shift.

2. 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.

3. When felling, keep at least 2 tree lengths away from your fellow workers.

4. Plan your work, ensuring an obstacle-free work area and, in the case of felling, at least one escape path from the falling tree.

5. 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.

6. When transporting your chain saw, use the appropriate transportation covers, which should be available for the guide bar and saw chain.

7. Do not attempt a pruning or limbing operation in a standing tree unless speciﬁcally trained to do so.

8. 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.

9. A chain saw is intended for two-handed use. Serious injury to the operator, helpers, and/or bystanders can result from onehanded operation.

10. See symbol deﬁnitions.

11. Keep other persons or animals a safe distance away from a running chain saw or the area where a tree is being felled.

12. Use extreme caution when cutting small brush and saplings because slender material can catch the saw chain and be whipped toward you.

13. When cutting a limb that is under tension or compression, be alert for springback.

14. 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.

CHAIN AND CHAIN BAR ASSEMBLY

1. Unpack all parts carefully.

2. Place the chain saw on any suitable ﬂat

surface.

3. Use only genuine WORX chains

designed for chainbar.

4. 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)

5. 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)

6. Check if all parts are seated properly and

hold chain and chain bar in a level position. (See Fig. C1)

7. Fit cover plate, ensure that the chain catch

bolt (20) ﬁts into the groove of the cover plate(11). (See Fig. C2)

8. 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”.

Do not use one handed when operating the chain saw.

Always use two hands when operating the chain saw.

Double insulation. When servicing, use only identical replacement parts.

10º

The chain saw kickback angle is 10º, with a chain brake.

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 chain tension.

WARNING: Cutting edges on chain

are sharp. Use protective gloves when handling chain.

WARNING: Maintain proper chain

tension always. A loose chain will increase the risk of kickback. A loose chain may jump out of guide bar groove. This may injure operator and damage

Electric chain saw EN

1514

chain. A loose chain will cause chain, chain bar, and sprocket to wear rapidly.

1. Place the chain saw on any suitable ﬂat surface.

2. 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)

3. 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)

4. 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:

1. Set chain saw on any suitable surface with

oil ﬁller cap facing upward.

2. Clean area around the oil ﬁller cap with

cloth unscrew cap.

3. Add WORX chain saw oil until reservoir is

full.

4. 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 developes, 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 (position )and 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 ).

CUTTING

Is the oil reservoir ﬁlled? Check oil level gauge

1514

Electric chain saw EN

1514

(19) prior to starting and regularly during operation. Reﬁll oil when oil level is low. The oil tank ﬁlling will last approx. 16minutes, depending on sawing intensity and stops. (Fig. G2) Check new replaced chain tension approx. every 10 minutes during operation.

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 ﬁngers must wrap around saw handles.(See Fig.H)

4. Make sure your footing is ﬁrm. Keep feet apart. Divide your weight evenly on both feet.

5. When ready to make a cut, push the lockoff 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.

6. When starting a cut, place moving chain against wood. Hold saw ﬁrmly in place to avoid possible bouncing or skating (sideways movement) of saw.

7. 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.

8. 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.

9. 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,
