General power tool safety warnings
WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below 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.GEB119-2

Cordless Chain saw safety warnings

1.  Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.

2. Always hold the chain saw with your right hand on the top handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.

3. Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

4. Wear safety glasses and hearing protection. Further protective equipment for the head, hands, legs, and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.

5. Always keep proper footing.

6. When cutting a limb that is under tension be alert for spring back. When the tension in the wood fibers is released the spring-loaded limb may strike the operator and/or throw the chain saw out of control.

7. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.

8. Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fits the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.

9. Follow instructions for lubricating, chain tensioning, and changing accessories. The improperly tensioned or lubricated chain may either break or increase the chance of kickback.

10. Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.

11. Cut wood only. Do not use a chain saw for purposes not intended. For example: do not use a chain saw for cutting plastic, masonry, or non-wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.

12. Causes and operator prevention of kickback: 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 sudden 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 personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
    • Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw, and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.
    014673
    • Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.
    • Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.
    • Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

13. Before starting work, check that the chain saw is in proper working order and that its condition complies with the safety regulations. Check-in particular that:
    • The run-down brake is working properly;
    • The bar and the sprocket cover are fitted correctly;
    • The chain has been sharpened and tensioned in accordance with the regulations.

14. Do not start the chain saw with the chain cover being installed on it. Starting the chain saw with the chain cover being installed on it may cause the chain cover to be thrown out forward resulting in personal injury and damage to objects around the operator.

Top handle chainsaw-specific safety warnings

1. This chain saw is designed especially for tree care and surgery. The chain saw is intended to be used by properly trained persons only. Observe all instructions, procedures, and recommendations from the relevant professional organization. Otherwise fatal accidents may occur. It is recommended that always use a rising platform (cherry picker, lift) for sawing in trees. Rappelling techniques are extremely dangerous and require special training. The operators must be trained to become familiar with safety equipment usage and climbing techniques. Always use the appropriate belts, ropes, and carabiners when working in trees. Always use restraining equipment for both the operator and the saw.
2. Perform cleaning and maintenance before storage in accordance with the instruction manual.
3. Ensure safe positioning of the chain saw during car transportation to avoid fuel or chain oil leakage, damage to the tool, and personal injury.
4. Do not fill the chain oil near the fire. Never smoke when you fill the chain oil.
5. National regulation may restrict the use of the chain saw.
6. If the equipment gets heavy impact or falls, check the condition before continuing work. Check the controls and safety devices for malfunction. If there is any damage or doubt, ask our authorized service center for the inspection and repair.
7. Hold the saw firmly in place to avoid skating (skid movement) or bouncing of the saw when starting a cut.
8. At the end of the cut, be careful to keep your balance due to the “drop”.
9. Take into account the direction and speed of the wind. Avoid sawdust and chain oil mist.

Protective equipment

1. In order to avoid head, eye, hand, or foot injuries as well as to protect your hearing the following protective equipment must be used during the operation of the chain saw: – The kind of clothing should be appropriate, i. e. it should be tight-fitting but not be a hindrance. Do not wear jewelry or clothing which could become entangled with bushes or shrubs. If you have long hair, always wear a hairnet!
   – It is necessary to wear a protective helmet whenever working with the chain saw. The protective helmet is to be checked at regular intervals for damage and is to be replaced after 5 years at the latest. Use only approved protective helmets.
   –The face shield of the protective helmet (or the goggles) protects against sawdust and wood chips. During operation of the chain saw always wear a goggle or a face shield to prevent eye injuries.
   – Wear adequate noise protection equipment (ear muffs, ear plugs, etc.)
   – The protective jacket consists of 22 layers of nylon and protects the operator against cuts. It is always to be worn when working from elevated platforms (cherry pickers, lifts), from platforms mounted on ladders or when climbing with ropes.
   – The protective brace and bib overall is made of nylon fabric with 22 layers and protect against cuts. We strongly recommend its use.
   – Protective gloves made of thick leather are part of the prescribed equipment and must always be worn during the operation of the chain saw.
   – During the operation of the chain saw safety shoes or safety boots fitted with anti-skid sole, steel toe caps, and protection for the leg must always be worn. Safety shoes equipped with a protective layer provide protection against cuts and ensure a secure footing. For working in trees the safety boots must be suitable for climbing techniques.

Vibration

1. Individuals with poor circulation who are exposed to excessive vibration may experience injury to blood vessels or the nervous system. Vibration may cause the following symptoms to occur in the fingers, hands, or wrists: “Falling asleep” (numbness), tingling,  pain, stabbing sensation, alteration of skin color or of the skin. If any of these symptoms occur,  see a physician!  To reduce the risk of “white finger disease”, keep your and warm during operation and well maintain the equipment and accessories.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing or removing the saw chain

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the saw chain.
• Always wear gloves when installing or removing the saw chain.
• Use only saw chain and guide bar with bar tip designed for this chain saw (see the Extract from the spare parts list).
• In order to prevent kickback, do not remove the bar tip or replace the guide bar with one without a bar tip.

Installing the saw chain
Fit in one end of the saw chain on the top of the guide bar. At this time, fit the saw chain as shown in the figure because it rotates in the direction of the arrow. (Fig. 4)
Place the saw chain so that the spring is positioned inside it and fits in the other end of the saw chain around the sprocket as shown in the figure. (Fig. 5)
While turning the guide bar counterclockwise, install it so that the end of the guide bar contacts the spring. (Fig. 6) Insert the hook of the sprocket cover into the hole in the tool and then place the sprocket cover on the tool. (Fig. 7) Turn the knob clockwise to tighten the screw firmly. (Fig. 8)

Removing the saw chain
Loosen the screw by turning counterclockwise the knob until the sprocket cover comes off. (Fig. 9)
Remove the sprocket cover. Remove the saw chain and guide bar from the tool.
Adjusting saw chain tension (Fig. 10 & 11)
Just a slight loosening of the screw allows the saw chain tension to be adjusted. After adjusting, retighten the screw firmly.

CAUTION:

• For a while, after a new saw chain is installed, it tends to become loosened. From time to time check the saw chain tension before use.
• Low tension of saw chain may cause coming out of place.
• Installing or removing the saw chain should be carried out in a clean place free from sawdust and the like.

Spike bumper (optional accessory) (Fig. 12)
To install the spiked bumper, perform the following steps:

1. Remove the sprocket cover, saw chain, and guide bar as described in this instruction manual.
2. Fit the holes of the spiked bumper along with the holes on the chainsaw.
3. Tighten them firmly with screws.

OPERATION

Lubrication (Fig. 13)
The saw chain is automatically lubricated when the tool is in operation.
Check the amount of remaining oil in the oil tank through the oil inspection window.
To refill the tank, remove the cap from the oil tank opening.
After refilling the tank, always screw provided oil tank cap on the chain aw.

CAUTION:

• When filling the chain saw with chain oil for the first time, or refilling the tank after it has been completely emptied, add oil up to the bottom edge of the filler neck. The oil delivery may otherwise be impaired.
• As a saw chain oil, use oil exclusively for Makita chain saws or oil available in the market.
• Never use oil including dust and particles or volatile oil.
• When pruning trees, use botanical oil. Mineral oil may harm trees.
• Never force the chain saw when pruning trees.
• Before cutting out, make sure that the provided oil tank cap is screwed in place.

Hold the chain saw away from the tree. Start it and wait until lubrication on the saw chain is adequate.
Bring the tip guide/lower guide into contact with the branch to be cut before switching on. Cutting without bringing the tip guide/lower guide into contact with the branch may cause the guide bar to wobble, resulting in injury to the operator.
Saw the wood to be cut by just moving it down.

Pruning trees
CAUTION:

• Keep all parts of the body away from the saw chain when the motor is operating.
• Hold the chain saw firmly with both hands when the motor is running.
• Do not overreach. Keep proper footing and balance at all times.

Bring the tip guide/lower guide into contact with the branch to be cut before switching on. Cutting without bringing the tip guide/lower guide into contact with the branch may cause the guide bar to wobble, resulting in injury to the operator. (Fig. 14 & 15)
When cutting thick branches, first make a shallow undercut and then make the finish cut from the top. (Fig. 16) If you try to cut off thick branches from the bottom, the branch may close in and pinch the saw chain in the cut. If you try to cut off thick branches from the top without a shallow undercut, the branch may splinter. (Fig. 17)
If you cannot cut the timber right through with a single stroke:
Apply light pressure to the handle and continue sawing and draw the chain saw back a little; then apply the spike a little lower and finish the cut by raising the handle. (Fig. 18) Carrying tool (Fig. 19)
Always remove the battery cartridge from the tool and overlap the guide bar with the scabbard before carrying the tool. Also, cover the battery cartridge with the battery cover.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
• Always wear gloves when performing any inspection or maintenance.
• Never use gasoline, benzene, thinner, alcohol, or the like. Discoloration, deformation, or cracks may result. Sharpening the saw chain

CAUTION:

• Always remove the battery cartridge and wear safety gloves when performing work on the saw chain. Sharpen the saw chain when:
  – Mealy sawdust is produced when damp wood is cut; – The chain penetrates the wood with difficulty, even when heavy pressure is applied;
  – The cutting edge is obviously damaged;
  – The saw pulls to the left or right in the wood. The reason for this behavior is the uneven sharpening of the saw chain or damage to one side only. (Fig.

Sharpen the saw chain frequently, but remove only a little material each time.
Two or three strokes with a file are usually sufficient for routine resharpening. When the saw chain has been resharpened several times, have it sharpened in a MAKITA specialist repair shop.
File and file guiding (Fig. 21)
– Use a special round file (optional accessory) for saw chains, with a diameter of 4 mm, to sharpen the chain. Normal round files are not suitable.
– The file should only engage the material on the forward stroke. Lift the file of the material on the return stroke.
– Sharpen the shortest cutter first. The length of this cutter is then the gauge dimension for all other cutters on the saw chain.
– Guide the file as shown in the figure.
– The file can be guided more easily if a file holder (accessory) is employed. The file holder has markings for the correct sharpening angle of 30° (align the markings parallel to the saw chain) and limits the depth of penetration (to 4/5 of the file diameter). Guide the file as shown in the figure. (Fig. 22)
– After sharpening the chain, check the height of the depth gauge using the chain gauge tool (optional accessory).
– Remove any projecting material, however small, with a special flat file (optional accessory).
– Round off the front of the depth gauge again.
– Wash away dust and particles from the saw chain after adjusting the height of the depth gauge.

Cleaning guide bar (Fig. 23)
Chips and sawdust will build up in the guide bar groove, clogging it and impairing oil flow. Always clean out the chips and sawdust when sharpening or replacing the saw chain.

Cleaning the oil filter at the oil discharge hole
Small dust or particles may be built up in the oil filter at the oil discharge hole during operation.
Small dust or particles built up in the oil filter may impair the oil discharge flow and cause insufficient lubrication on the whole saw chain.
When a poor chain oil delivery occurs at the top of the guide bar, clean the filter as follows.
Remove the battery cartridge from the tool.
Remove the sprocket cover and saw chain from the tool. (Refer to the section titled “Installing or removing saw chain”.)
Remove the push nut using a slotted bit screwdriver with a slender shaft or the like. (Fig. 24)
Take the filter out of the chain saw and remove small dust or particles from it. When the filter is too dirty, replace it with a new one.
(Fig. 25) Insert the battery cartridge into the tool.
Pull the switch trigger to flow built-up dust or particles of the oil discharge hole by discharging chain oil. (Fig. 26)
Remove the battery cartridge from the tool. Insert the cleaned oil filter into the oil discharge hole. When the filter is too dirty, replace it with a new one. (Fig. 27)
Insert the push nut with its correct side facing up as shown in the figure into the oil discharge hole to secure the filter. When the filter cannot be secured with a disfigured push nut, replace the push nut with a new one. (Fig. 28)
Reinstall the sprocket cover and saw chain on the tool.

Replacing the sprocket (Fig. 29 & 30)
Before fitting a new saw chain, check the condition of the sprocket.

CAUTION:

• A worn sprocket will damage a new saw chain. Has the sprocket been replaced in this case? The sprocket needs to be installed so that it always faces as shown in the figure.

Always fit a new locking ring when replacing the sprocket.
Replacing carbon brushes (Fig. 31 & 32)
Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones, and secure the brush holder caps.

Storing tool
Clean the tool before storing it. Remove any chips and sawdust from the tool after removing the sprocket cover. After cleaning the tool, run it under no load to lubricate the saw chain and guide bar.
Cover the guide bar with the scabbard.
Remove oil from the oil tank to empty it and place the chain saw with the tank cap facing upward.
To maintain product SAFETY and RELIABILITY, repairs, and any other maintenance or adjustment should be performed by Makita Authorized Service Centres, always using Makita replacement parts.
