- The file holder makes file guidance easier. It is marked for
the correct 30° sharpening angle (keep the marks parallel
with the chain when filing, see illustration) and limits the cut
depth to the correct 4/5 of the file diameter. See "Accesso-
ries" for the order number.

Cleaning the guide bar,

lubricating the sprocket nose
CAUTION:
Protective gloves must be worn.
H
Regularly inspect the bearing surfaces of the guide bar for
damage, and clean them with a suitable tool.
If the saw is used intensively it will be necessary to lubricate the
return sprocket bearings regularly (once a week). To do this,
first thoroughly clean the 2 mm hole at the tip of the guide bar,
and then press in a small amount of multi-purpose grease.
Multi-purpose grease and grease guns are available as acces-
sories.
Multi-purpose grease (order no. 944 360 000)

- After having sharpened the chain, the height of the depth
limiter must be checked by means of a chain gauge. See
"Accessories" for the order number.
- Correct even the smallest excess height with a special flat
file (F). See "Accessories" for the order number.

Replacing the saw chain

CAUTION: Use only chains and guide bars designed for
this saw (see the Extract from the spare-parts list)!

I
Check the sprocket (I/1) before mounting a new chain.
The sprocket is located underneath the clutch drum (I/2).
CAUTION:
Worn out sprockets (J) 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 centre.
Cause
no power supply, cable defective
chain brake actuated
carbon brushes worn
oil tank empty,
oil guide groove dirty
oil-pump adjusting screw incorrectly adjusted
