Replacing the saw chain
CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare parts list)!
A | 1 | B |
Check the sprocket (A/1) before mounting a new chain.
The sprocket is located underneath the clutch drum (I/2).
CAUTION:
Worn out sprockets (B) may damage the new chain and must therefore be replaced.
Do not attempt to replace the sprocket yourself. Sprocket replacement requires special training and tools and must be done at a MAKITA service center.
Inspecting and replacing the carbon brushes
IMPORTANT:
Inspect the carbon brushes at regular intervals! A notch on the brush shows the limit of wear.

NOTE:
The carbon brush is very delicate, so be careful not to let it drop.
When taking it out, be sure to note the position it was installed in, since each brush is run in with the rotor.
-Use the combination wrench to unscrew the cover (C/2), and then pull out the brush (C/3).
-If the wear limit has not yet been reached, put the brush back in the same position and screw the cover (C/2) back on.
-Run the saw briefly (about a minute) so the brushes can run in again.
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.
