Replacing The Saw Chain; Inspecting And Replacing The Carbon Brushes - Makita UC3030A Instruction Manual

Replacing the saw chain

CAUTION:
Use only chains and guide bars designed for this saw!
Check the sprocket (1) before mounting a new chain.
CAUTION:
Worn out sprockets (2) may damage the new chain and must
therefore be replaced.
Do not attempt to replace the sprocket yourself. Sprocket replace-
ment requires special training and tools and must be done at a
MAKITA service centre.

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 in-
stalled in, since each brush is run in with the rotor.
- Use a slotted bit screwdriver to unscrew the cover (1), and
then pull out the brush (2).
- If the wear limit has not yet been reached, put the brush back
in the same position and screw the cover (1) back on.
-­ Run t he s aw b riefly ( about a m inute) s o t he b rushes c an r un
in again.
Important: Now test the run-out brake (see page 18). If the saw
chain does not come to a full stop within two second, run the
saw again briefly and repeat the test until the brake functions
properly.
NOTE: After installing new carbon brushes, run the saw about
5 minutes and then check the run-out brake.
