GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. WORK AREA SAFETY
   • Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
   • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. ELECTRICAL SAFETY
   • Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
   • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
   • If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3. PERSONAL SAFETY
   • Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
   • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
   • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   • Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
   • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
4. POWER TOOL USE AND CARE
   • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   • Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   • Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
5. BATTERY TOOL USE AND CARE
   • Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   • Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   • When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
   • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
6. SERVICE
   Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

19. Guard Against Kickback

WARNING!

• KICKBACK may occur when the nose or tip of the guide bar touches and object, or when the wood closes in and pinches the saw chain in the cut.
• Ti 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 jaw saw firmly with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the jaw 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. Use devices such as low kickback chain, guide bar nose guards, chain brakes and special guide bars that reduce the risks associated with kickback.
6. Only use replacement bars and chains specified by the manufacturer or the equivalent.

ADDITIONAL SAFETY WARNINGS FOR JAWSAW®

1. Pre-plan a safe exit from falling branches and debris. Ensure the exit route is clear of obstacles that would prevent or hinder movement. Remember freshly cut bark and wet grass is slippery.
2. Be aware of the direction that a branch may fall. Consider all conditions that may affect the direction of fall. Including:
   • The intended direction of fall.
   • The natural lean of the branch.
   •  Any unusual heavy limb structure or decay.
   • Surrounding trees and obstacles including overhead power lines.
   • The wind speed and direction.
3. The safe distance between a branch and debris to be felled and bystanders, buildings, and other objects is at least 2 ½ times the length of the branch. Any bystander, building, or object within this distance is at risk from being struck by the falling branch.
4. Do not let the moving chain contact any object at the tip of the guide bar.
5. Begin and continue cutting only with the chain moving at full speed.
6. When using the Extension pole to cut the branches on a tree, make sure to keep a firm footing and balance. Do not stand the position where the branch may land after being cut.
7. Before cutting is started, consider the natural lean of the tree, the wind direction to judge which way the branch will fall.
8. Remove dirt, stones, loose bark, nails, staples, and wire from the branch where you plan to make your cut.
9. The machine shall not be used in any position that causes any part to come within 33 feet (10m) of overhead electrical lines;
10. The operating positions are dangerous; the operator may be struck by falling branches or by those that rebound after hitting the ground. Remove the branches in sections.
11. Do not use this tool to cut branches or limbs over 4 inches (10 cm) in diameter, the branch or limb must fit completely in the jaw opening.

ADJUSTING THE CHAIN TENSION

1. push the Rear Handle (1) until the Guide Bar (7) is in the middle of the jaw opening as shown. Lock the Guide Bar in the middle position by inserting the Lock Pin (12) into the Lock Pin Receptacle(13) located under the Rear Handle (1) (See Fig. B1-B3).

2. Open the Chain Access Cover (9) by using the supplied wrench. To open turn the Access Cover Nut no more than a 1/4 turn in either direction. (See Fig. C)

3. Release tension on the Saw Chain (8) by loosening the Chain Tensioning Bolt (10). Turn the Chain Tensioning Bolt counterclockwise 2 or more times. (See Fig. D)

4. Add tension on the Saw Chain by turning the Chain Tensioning Bolt clockwise. When tightening the Chain Tensioning Bolt the automatic chain tensioning system will set the tension to the Saw Chain at the same time.
   NOTE: It is not possible to overtighten the Saw Chain, so tighten the chain as much as possible.

5. Check that the correct Saw Chain tension has been set. It should be possible to pull the Saw Chain away from the side of the Guide Bar approximately 3mm and it should snap back. (See Fig. E).
   If tension is incorrect, repeat step 3, ensuring the Guide Bar is free to move when the tension is released.

CHANGING THE GUIDE BAR AND SAW CHAIN

WARNING:

• Laceration hazard. Always wear protective gloves when installing or removing the saw chain. The saw chain is sharp and can cut you even when it is not running.
• Burn hazard. The chain guide bar and chain may become hot during use. Allow to cool before adjustment or removal.

1. Ensure the operation is carried out on a firm surface.
2. Disconnect the power, install the Lock Pin (12) and open the Chain Access Cover (9) as described in the previous section.
3. Use only WORX replacement Guide Bar and Saw Chain.
4. Loosen and remove the Chain Tensioning Bolt (17).
5. Lift the Guide Bar (7) and Saw Chain (8) out through the jaw, angling the Guide Bar to clear the two bar locating pins (d) (See Fig. I).
6. If replacing the Guide Bar, remove the mounting plate (a), which is retained by a single screw and fit to the new Guide Bar. The Guide Bar is symmetrical and may be mounted with either face outward (can be reversed if the lower working edge is worn) (See Fig. F).
7. Before re-fitting the Guide Bar, check that the small oil hole (b) and chain slot (c) are not blocked by dirt or sawdust, use a small toothpick to clean if necessary (See Fig. G1,G2).

LUBRICATION

IMPORTANT: The JAWSAW® is shipped with an empty oil tank. It is essential to fill with chain oil before use. Bar and chain oil (32#) of any brand can be used.
Never operate the JAWSAW® without chain oil or an empty tank as this will result in poor cutting performance, motor overload and possible burn-out.

FILLING OIL TANK:

1. Fill Oil Bottle (19) with chain and bar oil. (See Fig. K)
2. Rest the JAWSAW® with the Oil Filler facing upward.
3. Uncrew the oil filler cap (g) open.
4. Use bottle to fill oil reservoir. (See Fig. L)
5. Screw the oil filler cap.
   IMPORTANT: Use only the recommended oil to avoid damage to the JAWSAW®. Never use recycled/ old oil. Use of non approved oil will invalidate the warranty.

CHECKING THE AUTOMATIC OILER
The JAWSAW® uses a much lower chain speed than a conventional chainsaw so it needs much less oil.
However it is very important that it always has oil. Check the Oil Level Window (14) and refill as
necessary. During operation, periodically check the Saw Chain (8) and Guide Bar (7). A slight oil presence should be visible. If the chain and bar appear completely dry, then remove the bar and chain (see previous section) to ensure the bar oil hole is not blocked. If the oil hole is clear, there is oil in the tank and still no oiling of the chain is visible – contact WORX customer service.

WARNING: Do not push the rear handle repeatedly when the saw is not cutting. The oil will be bumped out when pushing the handle whether the motor runs or not.

OPERATION

1. BEFORE USING YOUR CORDLESS JAWSAW®
   Your battery pack is UNCHARGED and you must charge once before use The battery charger supplied is matched to the Li-ion battery installed in the machine. Do not use another battery charger.

2. CHARGING YOUR BATTERY PACK
   The Li-ion battery is protected against deep discharging. When the battery is empty, the machine is switched off by means of a protective circuit.

• To switch on, press either Lock Out Button with your thumb and squeeze the Trigger Switch (See Fig N).
• To switch off, just release the Trigger Switch.

Cutting
Check oil level window (14) prior to starting and regularly during operation. Refill oil when oil level is low.

If operating with a newly replaced Saw Chain (8), check the chain tension around every 10 minutes during operation.
Always hold the Front Handle (4) firmly when cutting (See Fig. O1, O2)

1. Use both hands to grip saw firmly. Always use your left hand (I) to grip the front handle and your right hand (II) to grip the Rear Handle(1). Thumbs and fingers must wrap around saw handles (See Fig. O1, O2).

2. IMPORTANT: Make sure your footing is firm and stable. Do not use the JAWSAW® while standing on piles of branches or while standing on a ladder.
   HINT: When cutting branches which are lying on the ground, place one foot on the branch to prevent limb from moving (See Fig. P).
   WARNING! Do not put your foot in the Jaw opening, keep your foot a safe distance from the tool. (See Fig. P)

3. Position the tool with the Jaw placed over the desired branch to be cut.
   WARNING! DO NOT force the cut. Let the Saw Chain pull through the wood.
   WARNING! When starting the saw make sure the chain is not in contact with the limb or branch to be cut.

4. Switch on the tool.

5. Push the Rear Handle towards the Front Handle to complete the cut.

6. Switch off the tool after the Guide Bar and Saw Chain have returned to their starting position.

WARNING:

• When completing the cut (step 6 above) do not push the handle forcefully, let the spinning chain pull itself through the wood.
• Using too much force on the rear handle when cutting can overload the tools motor.
  CAUTION: At the end of each cut be prepared to support the tools weight.

Trimming branches:

Before cutting any branch, you must consider the following:

1. Is the branch heavy, will it damage anything when it falls?
   • Large branches should be cut in small sections starting at the farthest end from the tree.
   • Always check where the branch will fall BEFORE commencing the cut.
   • Never stand under a branch being cut.
2. Will the branch split before it is cut through? (See Fig. Q1,Q2)
   • To prevent splitting, turn the JAWSAW® upsidedown and make a small cut (less than 1/3 diameter of the limb) from the underside.
   • Then turn the JAWSAW® over to the normal position and cut from top down, slightly further out from the trunk than the initial undercut.
3. 4. Is the branch under tension, will it spring suddenly or trap the saw when it is cut?
   • Always stand outside the path of a springy branch. It can strike suddenly with surprising force and cause injury or loss of control of the saw.
   • Always cut from the tension side of a branch, usually the top of a branch on a standing tree, but can be any side of the branch of a fallen tree.
   • If the cut starts to close on the saw, you are cutting from the wrong side, keep the saw running and pull the saw to retract the blade from the cut.
   • If the saw becomes trapped do not try to pull it out with excessive force, lift the branch to open the cut while an assistant removes the saw.

Kickback safety
This saws chain is covered by a guard however, kickback can still occur. 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.
• Keep solid footing and balance at all times.
• Stand slightly to right side of saw. This keeps your body from being in direct line with Saw Chain.
• Do not let guide bar nose touch anything when Saw Chain is moving.
• Do not bury Guide Bar nose or try to plunge cut (boring into wood using bar nose).
• Watch for shifting of wood or other forces that may pinch Saw Chain.
• Use extreme caution when reentering a previous cut.
• Never use a dull or loose Saw Chain. Keep Saw Chain sharp with proper tension.

PROPERLY USING THE JAWSAW®
Use the JAWSAW® only with secure footing. Hold the JAWSAW® at the right-hand side of your body. (See Fig. R)
The Saw Chain must be running at full speed before it makes contact with the wood. Use the metal Jaw Teeth (6) to secure the saw onto the wood before starting to cut. (See Fig.S) Do not operate the JAWSAW® with arms fully extended or attempted to saw areas which are difficult to reach, or on a ladder. (See Fig. T) Cutting wood under tension (See Fig. U)

WARNING:

• When cutting a limb that is under tension, use extreme caution.
• Be alert for wood springing back. When wood tension is released, the 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 JAWSAW® 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 tool.

LIMBING A TREE (See Fig. V)

****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 against the ground should be cut from the bottom up to avoid binding the JAWSAW®

Bucking a log (See Fig. W)
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. Follow the simple directions for easy cutting.

WARNING: (See Fig. X)

• 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. (See Fig. X)
• 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 or leg.
• While cutting log, never allow another person to hold log.
• Turn off the saw before moving from one place to another.

ASSEMBLING THE EXTENSION POLE (WG321)(WHEN USED WITH OPTIONAL POLE ATTACHMENT)

WARNING: Before attaching the Extension Pole (20), make sure that the tool is switched off and the battery is removed.

1. Turn the release lever to allow the handle clamp to spring open (See Fig. Y1).
2. With the Extension Pole slightly angled away from the tool, insert the steel tab into the slot (I) behind the Front Handle(4), then swing the pole towards the tool’s Rear Handle(1) (See Fig Y2).
3. Position the Extension Pole handle clamp inside the JAWSAW® ’s Rear Handle as shown in Fig Y3. To allow the clamp to properly fit the handle, push the lockout button and depress the trigger.

SAW MAINTENANCE AND KICKBACK SAFETY
Follow maintenance instructions in this manual. Proper cleaning and maintenance of the Saw Chain (8) and Guide Bar (7), as well as the JAWSAW® in general, 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.

MAINTENANCE AND STORAGE OF JAWSAW®

1. Remove the battery pack from the saw:
   • When not in use.
   • When transporting.
   • When left unattended.
   • Before servicing.
   • Before cleaning.
   • Before changing accessories or attachments, such as Saw Chain and Guard Bar.
2. Inspect the saw before and after each use for:
   • Any signs of damage
   • Smooth action of push handle and movement of bar.
   • Adequate Chain Tension; you should be able to lift the Saw Chain from the Guide Bar no more than 1.6mm.
   • Adequate chain lubrication.
3. Do not use the JAWSAW® , if:
   • The Trigger Switch (2) or Lock Out Button (3) is malfunctioning.
   • The Rear (Push) Handle (1) does not smoothly return under spring force.
   • Any other damage which affects the safety or operation is evident.
4. Maintain the JAWSAW® with care and have any damage or malfunction repaired by an authorized service center:
   • Never expose the JAWSAW® to rain.
   • Keep Saw Chain sharp, clean, and lubricated for better and safer performance.
   • Follow steps outlined in this manual to sharpen Saw Chain.
   • Keep handles clean and free from oil.
   • Keep all screws and nuts tight.
5. When servicing, use only identical replacement parts.
6. When not in use, always store JAWSAW®
   • In a high or locked place, out of children’s reach.
   • In a dry place.

REPLACING SAW CHAIN/CHAIN BAR

Replace the Saw Chain when cutters are too worn to sharpen or when the chain breaks. Only use replacement chain noted in this manual. Always include new drive Sprocket (16) when replacing the Saw Chain. This will maintain proper driving of chain. Inspect Guide Bar (7) before sharpening chain. A worn or damaged guide bar is unsafe. A worn or damaged Guide Bar is unsafe, will damage the Saw Chain, and will make cutting harder. For Replacing the Guide Bar please refer to CHANGING THE GUIDE BAR AND CHAIN section in the Adjustment and Assembly Instructions.

SHARPENING SAW CHAIN

WARNING: Remove the battery pack from the saw before servicing.

• Cutting edges on chain are sharp.
• Use protective gloves when handling chain.
• Keep Saw Chain sharp. Your saw will cut faster and more safely. A dull Saw Chain will cause undue Sprocket (16), Guide Bar (7), Saw Chain, and motor wear. If you must force the Saw Chain into wood and cutting creates only sawdust with few large chips, then the Saw Chain is dull.

LUBRICATING THE CHAIN WHEEL

NOTE: It is not necessary to remove the the chain or bar when lubricating the chainwheel.

1. Clean the Guide Bar and chain wheel.
2. Using a grease gun, insert the tip of the gun into the lubrication hole (h) and inject grease until it appears at the outside edge of the chainwheel tip (See Fig. AA).
3. You may need to rotate the chainwheel (I) in order to grease all areas of the wheel.
   To do this, pull the Saw Chain by hand to rotate the chainwheel and align the parts of the wheel that needs to be greased with the lubrication hole. (See Fig. AA)

CLEANING
Regularly open the Chain Access Cover (9) and remove any debris that has become trapped.
Regularly clean the ventilation slots with a clean, dry paint brush.
To clean the tool, use only mild soap and a damp cloth. Never let any liquid get inside the tool and never immerse any part of the tool into liquid.

TRANSPORTING
Always transport the tool with the Guide Bar (7) and Saw Chain (8) inside the protection guard.
