16. If branches get caught in the tool, always stop the tool and remove the battery cartridge or the spark plug cap. Otherwise, an unintentional start may cause serious injury.

17. If the saw chain becomes clogged, always switch off the tool and remove the battery car-tridge or the spark plug cap before cleaning.

18. Accelerating the tool with the saw chain blocked increases the load and will damage the tool.

19. Before cutting limbs, keep an escape area away from the falling limb. First, clear obstructions such as limbs and branches from the work area. Move all tools and goods from the escape area to another safe place.

20. Before cutting branches and limbs, check the falling direction of them, considering the condition of branches and limbs, adjoining trees, wind direction, etc. Pay full attention to the falling direction, and the rebound of the branch, which hit the ground.

21. Never hold the tool at an angle of more than 60°. Otherwise falling objects can hit the operator and cause serious injury. Never stand underneath the limb being cut.

22. Pay attention to broken or bent branches. They may bounce back in cutting, causing unexpected injury.

23. Before cutting limbs that you intend to cut, remove branches and leaves around them. Otherwise, the saw chain may be caught by them.

24. To prevent the saw chain from being caught in the kerf, do not release the lever before pulling the saw chain out of the kerf.

25. If the saw chain is bound in the kerf, immedi-ately stop the tool, carefully move the branch to open the kerf, and release the saw chain.

26. Avoid kickback (rotational reactive force towards the operator). To prevent kickback, never use the guide bar nose or perform a penetrating cut. Always beware of the position of the guide bar nose.

27. Check the chain tension frequently. When checking or adjusting the chain tension, switch off the tool and remove the battery cartridge or the spark plug cap. If the tension is loose, tighten it.

28. Pay attention to the environment. Avoid unnecessary throttle operation for less pollution and noise emissions. Adjust the carburetor correctly.

OPERATION

Lubrication

• NOTICE: When filling the 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.
• NOTICE: Use the saw chain oil exclusively for Makita chain saws or equivalent oil available in the market.
• NOTICE: Never use oil including dust and particles or volatile oil.
• NOTICE: When pruning trees, use botanical oil. Mineral oil may harm trees.
• NOTICE: Before the cutting operation, make sure that the oil tank cap is tightened securely.

The Saw chain is automatically lubricated when the tool is in operation. Check the amount of remaining oil in the oil tank periodically.

To refill the tank, place the tool on a flat surface, then push the button on the oil tank cap so that the button on the other side stands up, and then remove the oil tank cap by turning it. The proper amount of oil is 160 ml (5.4 fl oz). After refill-ing the tank, make sure that the oil tank cap is tightened securely.

NOTE: If it is difficult to remove the oil tank cap, insert the box wrench into the slot of the oil tank cap, and then remove the oil tank cap by turning it counterclockwise.

After refilling, hold the tool away from the tree. Start it and wait until lubrication on the saw chain is adequate.

Working with the tool

• CAUTION: Keep all parts of the body away from the saw chain when the motor is operating.
• CAUTION: Hold the tool firmly with both hands when the motor is running.
• CAUTION: Do not overreach. Keep proper footing and balance at all times.
• CAUTION: When cutting through branches, be careful not to lose your balance due to the weight of the tool head.
• CAUTION: Always keep the escape route in case a cut branch falls towards the operator.
• CAUTION: Never use the tip of the guide bar for cutting. Otherwise, dangerous kickbacks may occur, and it may result in personal injury.
• NOTICE: Never toss or drop the tool.
• NOTICE: Do not cover the vents of the tool.
• NOTICE: Do not force the tool. Otherwise, it may damage the tool.

Stand on a stable surface, and hold the tool away from the branches so that the angle of the tool becomes 60° or less against the horizontal ground.

Start the tool, and then press the saw chain onto the branch lightly. When cutting long branches, to control the drop position of cut branches, divide the branch into sections and cut the branch from the tip. Pay attention to the falling branches since they may bounce in the direction of the operator after hitting the ground.

When cutting thick branches, first make a shallow undercut and then make the finish cut from the top.

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.

Carrying tool
Before carrying the tool, always remove the battery cartridge or the spark plug cap, and then attach the guide bar cover. Also, cover the battery cartridge with the battery cover.

MAINTENANCE

• CAUTION: Always be sure that the motor is switched off and the battery cartridge or the spark plug cap is removed before attempting to perform inspection or maintenance.
• CAUTION: Always wear gloves when performing any inspection or maintenance.
• NOTICE: Never use gasoline, benzine, thinner, alcohol, or the like. Discoloration, deformation, or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, and any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

Sharpening 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 damaged;
• The saw pulls to the left or right in the wood. (caused by uneven sharpening of the saw chain or damage to one side only)

Sharpen the saw chain frequently but a little each time. Two or three strokes with a file are usually sufficient for routine resharpening. When the saw chain has been resharpened sev-eral times, has it sharpened in our authorized service center?

Sharpening criteria

WARNING: An excessive distance between the cutting edge and depth gauge increases the risk of kickback.

1. 1. Cutter length 2. Distance between cutting edge and
   depth gauge 3. Minimum cutter length (3 mm (1/8″))

   • All cutter lengths must be equal. Different cutter lengths prevent the saw chain from running smoothly and may cause the saw chain to break.
   • Do not sharpen the chain when the cutter length has reached 3 mm (1/8″) or shorter. The chain must be replaced with a new one.
   • The chip thickness is determined by the distance between the depth gauge (round nose) and the cutting edge.
   • The best cutting results are obtained with the following distance between the utting edge and dtheepth gauge.
   • Chain blade 90PX : 0.65 mm (1/32″)
   • Chain blade 91PX : 0.65 mm (1/32″)
   • The sharpening angle of 30° must be the same on all cutters. Different cutter angles cause the chain to run roughly and unevenly, accelerate wear, and lead to chain breaks.
   • Use a suitable round file so that the proper sharpening angle is kept against the teeth.
   • Chain blade 90PX : 55°
   • Chain blade 91PX : 55°

File and file guiding

• Use a special round file (optional accessory) for saw chains to sharpen the chain. Normal round files are not suitable.
• The diameter of the round file for each saw chain is as follows:
  • Chain blade 90PX : 4.5 mm (3/16″)
  • Chain blade 91PX : 4.0 mm (5/32″)
• The file should only engage the cutter on the forward stroke. Lift the file of the cutter on the return stroke.
• Sharpen the shortest cutter first. Then the length of this shortest cutter becomes the standard 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 (optional 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).
• 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.

Cleaning the guide bar
Chips and sawdust will build up in the guide bar groove. They may clog the bar groove and impair the oil flow. Clean out the chips and sawdust whenever you sharpen or replace the saw chain.

Cleaning the sprocket cover
Chips and sawdust will accumulate inside the sprocket cover. Remove the sprocket cover and saw chain from the tool then clean the chips and sawdust.

Cleaning the oil discharge hole
Small dust or particles may build up in the oil discharge hole during operation. These dust or particles may impair the oil flow and cause insufficient lubrication on the whole saw chain. When a poor chain oil delivery occurs at the top ofthe guide bar, clean the oil discharge hole as follows.

1. Remove the sprocket cover and saw chain from the tool.
2. Remove the small dust or particles using a slotted screwdriver or the like.
3. Install the battery cartridge to the power unit or attach the spark plug cap to the power unit. Pull the switch trigger to flow built-up dust or particles off the oil discharge hole by discharging chain oil.
4. Remove the battery cartridge from the power unit or remove the spark plug cap from the power unit. Reinstall the sprocket cover and saw chain on the tool.

Replacing the sprocket

CAUTION: A worn sprocket will damage a new saw chain. Have the sprocket replaced in this case.

Before fitting a new saw chain, check the condition of the sprocket. If the sprocket is worn or damaged, ask Makita Authorized Service Centers for replacement.
