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 escape route in case a cut branch falls towards the operator.
CAUTION: Never use the tip of the guide bar for cutting. Otherwise, dangerous kickback 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.

Fig.32:
60° or less

Start the tool, and then press the saw chain onto the branch lightly.

When cutting long branches, in order to control the drop position of cut branches, divide the branch in 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.
Fig.33

When cutting thick branches, first make a shallow undercut and then make the finish cut from the top.
Fig.34

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.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and the battery cartridge 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, 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 obviously 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 several times, have 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.

Fig.43:

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

• All cutter length 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 or shorter. The chain must be replaced with 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 following distance between cutting edge and depth gauge.
  • Chain blade 90PX : 0.65 mm
  • Chain blade 91PX : 0.65 mm

Fig.44

• 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.
• Diameter of the round file for each saw chain is as follows:
  • Chain blade 90PX : 4.5 mm
  • Chain blade 91PX : 4.0 mm
• The file should only engage the cutter on the forward stroke. Lift the file off 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.

Fig.45:

1. File
2. Saw chain

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).

Fig.46:
File holder

After sharpening the chain, check the height of the depth gauge using the chain gauge tool (optional accessory).

Fig.47

• 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 every time when you sharpen or replace the saw chain.
Fig.48

Cleaning the sprocket cover

Chips and saw dust will accumulate inside of the sprocket cover. Remove the sprocket cover and saw chain from the tool then clean the chips and saw dust.
Fig.49

Cleaning the oil discharge hole

Small dust or particles may be built up in the oil discharge hole during operation. These dust or particles may impair the oil to flow and cause an insufficient lubrication on the whole saw chain. When a poor chain
oil delivery occurs at the top of 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.
   Fig.50:

3. Slotted screwdriver

4. Oil discharge hole

5. Insert the battery cartridge into the tool. Pull the switch trigger to flow built-up dust or particles off the oil discharge hole by discharging chain oil.

6. Remove the battery cartridge from the tool. 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.

2. Areas to be worn out

Storing the tool

1. Clean the tool before storing. Remove any chips and sawdust from the tool after removing the sprocket cover.
2. After cleaning the tool, run it under no load to lubricate the saw chain and guide bar.
3. Cover the guide bar with the guide bar cover, and then shorten the pipe.
4. Empty the oil tank.
