CAUTION: If the upper edge of the bar is used
for cutting, the chain saw may be deflected in your
direction if the chain becomes trapped. For this
reason, cut with the lower edge, so that the saw
will be deflected away from your body.
► Fig.24
When you cut a wood under tension, cut the pressured
side (A) first. Then make
the final cut from
the tensioned side (B).
This prevents the bar
from becoming trapped. ► Fig.25
Limbing
CAUTION: Limbing may only be performed by
trained persons. A hazard is presented by the risk of
kickback.
When limbing, support the chain saw on the trunk if
possible. Do not cut with the tip of the bar, as this
presents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below. Do not
stand on the felled trunk when limbing.
Carrying tool
Before carrying the tool, always apply the chain brake
and remove the battery cartridges
from the tool. Then attach the
guide bar cover. Also cover the battery cartridge with
the battery cover.

cover
MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
CAUTION: Always wear gloves when
performing any inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
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.
Sharpening the saw chain
Sharpen the saw chain when:
• Mealy sawdust is produced
when damp wood is
cut;
• The chain penetrates the wood
with difficulty, even when
heavy pressure is applied;
• The cutting edge is obviously
damaged;
• The saw pulls to the
left or right in
the wood. (caused by uneven
sharpening of the saw chain or damage to one
side only)
Sharpen the saw chain frequently
but a little each time.
Two or three strokes with
a file are usually sufficient
for routine resharpening. When the saw chain
has been resharpened several times, have it sharpened
in our authorized service center.
Sharpening criteria:
WARNING: An excessive distance between
the cutting edge and depth gauge increases the
risk of kickback.
► Fig.27: 1. Cutter length 2. Distance
between cutting edge and depth gauge 3.
Minimum cutter length (3 mm)
— All cutter length must be
equal. Different cutter lengths
prevent the saw chain from running smoothly and
may cause the saw chain to break.
— Do not sharpen the chain when the cutter length
has reached 3 mm or
shorter. The chain must
be replaced with new one.
— The chip thickness is
determined by the distance
between the depth gauge (round nose) and
the cutting edge.
— The best cutting results are
obtained with following distance
between cutting edge and depth gauge.
• Chain blade 90PX :
0.65 mm
• Chain blade 91PX :
0.65 mm
• Chain blade 25AP :
0.65 mm
► Fig.28
— The sharpening angle of 30°
must be the same
on all cutters. Different cutter
angles cause the chain to run roughly and
unevenly, accelerate wear, and lead to chain
breaks.
— Use a suitable round file
so that the proper
sharpening angle is kept against the teeth.
