Reinstall the sprocket cover and saw chain on the tool.
Replacing the sprocket (Fig. 29 & 30)
Before fitting a new saw chain, check the condition of the
sprocket.
CAUTION:
• A worn sprocket will damage a new saw chain. Have
the sprocket replaced in this case. The sprocket need
to be installed so that it always faces as shown in the
figure.
Always fit a new locking ring when replacing the
sprocket.
Replacing carbon brushes (Fig. 31 & 32)
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
Storing tool
Clean the tool before storing. Remove any chips and
sawdust from the tool after removing the sprocket cover.
After cleaning the tool, run it under no load to lubricate
the saw chain and guide bar.
Cover the guide bar with the scabbard.
Remove oil from the oil tank to empty it and place the
chain saw with the tank cap facing upward.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centres, always
using Makita replacement parts.
