— Guide the file as shown in the figure.
► Fig.24: 1. File 2. Saw chain
— The file can be guided more easily if a file holder
(optional accessory) is employed. The file holder
has markings for the correct sharpening angle of
30° (align the markings parallel to the saw chain)
and limits the depth of penetration (to 4/5 of the
file diameter).
► Fig.25: 1. File holder
— After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional
accessory).
► Fig.26
— Remove any projecting material, however small,
with a special flat file (optional accessory).
— Round off the front of the depth gauge again.
Cleaning the guide bar
Chips and sawdust will build up in the guide bar groove.
They may clog the bar groove and impair the oil flow.
Clean out the chips and sawdust every time when you
sharpen or replace the saw chain.
► Fig.27
Cleaning the sprocket cover
Chips and saw dust will accumulate inside of the
sprocket cover. Remove the sprocket cover and saw
chain from the tool then clean the chips and saw dust.
► Fig.28
Cleaning the oil discharge hole
Small dust or particles may be built up in the oil dis-
charge hole during operation. These dust or particles
may impair the oil to flow and cause an insufficient
lubrication on the whole saw chain. When a poor chain
oil delivery occurs at the top of guide bar, clean the oil
discharge hole as follows.
1. Remove the sprocket cover and saw chain from
the tool.
2.
Remove the small dust or particles using a slotted
screwdriver or the like.

3. Install the battery cartridge to the power unit or
attach the spark plug cap to the power unit. Pull the
switch trigger to flow built-up dust or particles off the oil
discharge hole by discharging chain oil.
4.
Remove the battery cartridge from the power
unit or remove the spark plug cap from the power unit.
Reinstall the sprocket cover and saw chain on the tool.
Replacing the sprocket
CAUTION:
A worn sprocket will damage a
new saw chain. Have the sprocket replaced in this
case.
Before fitting a new saw chain, check the condition of
the sprocket. If the sprocket is worn or damaged, ask
Makita Authorized Service Centers for replacement.
