MAINTENANCE

WARNING:
• Make sure that the chain saw is switched off the engine and pull the plug cap off
the spark plug before performing maintenance or inspection.
• Wait until the engine cools down before performing any maintenance work.
• Always wear protective gloves.
• Start the chain saw only after having assembled and inspected it completely.
• Keep away from open flames and do not smoke.
CAUTION:
• To maintain product SAFETY and RELIABILITY, any repair, maintenance or
adjustment work that is not included in this manual should be performed by
Makita Authorized Service Centers. Always use Makita replacement parts.

Sharpening the saw chain

The chain needs sharpening when:
• Chips produced by cutting look like sawdust.
• The chain penetrates the wood only under great pressure.
• The cutting edge is visibly damaged.
• The saw is pulled to the left or right when sawing. This is caused by uneven
sharpening of the chain.
NOTICE:
• Sharpen frequently, but without removing too much. Generally, two or three
strokes of the file are enough.
• Have the chain resharpened at a service centre when you have already
sharpened it yourself several times.
Proper sharpening
CAUTION:
• Use only chains and guide bars designed for this saw.
• Excessive depth (3) increases the risk of kickback.
Sharpening criteria (for saw chain 91PX)
- Maintain all cutter parts (1) on the saw chain the same length. Cutter parts with
different lengths result in rough running of the chain and can cause cracks in the
chain.
- The minimum cutter length (2): 4 mm. Do not sharpen the chain when the cutter
part length becomes less than 4 mm. At this point, replace the saw chain.
- The depth of the cut (3) is determined by the difference in height between the
depth gauge (round nose) and the cutting edge.
- The best results are obtained with 0.64 mm (.025") of the depth.
- Maintain the same sharpening angle of 30° for all the cutter parts.
- Use a proper round file so that proper sharpening angle of 55° is kept against the
teeth.
- Sharpen the cutters with proper angle, otherwise it may cause rough and irregular
chain running, and result in increasing wear and breakage of the saw chain.
