Maintenance - Makita DUA301 Instruction Manual

Working with the tool
CAUTION:
Keep all parts of the body away
from the saw chain when the motor is operating.
CAUTION:
Hold the tool firmly with both
hands when the motor is running.
CAUTION:
Do not overreach. Keep proper
footing and balance at all times.
CAUTION:
When cutting through branches,
be careful not to lose your balance due to the
weight of the tool head.
CAUTION:
Always keep escape route in case
a cut branch falls towards the operator.
CAUTION:
Never use the tip of the guide bar
for cutting. Otherwise, dangerous kickback may
occur, and it may result in personal injury.
NOTICE:
Never toss or drop the tool.
NOTICE:
Do not cover the vents of the tool.
NOTICE:
Do not force the tool. Otherwise, it may
damage the tool.
Stand on a stable surface, and hold the tool away from
the branches so that the angle of the tool becomes 60°
or less against the horizontal ground.
► Fig.30: 1. 60° or less
Start the tool, and then press the saw chain onto the
branch lightly.
When cutting long branches, in order to control the drop
position of cut branches, divide the branch in sections
and cut the branch from the tip. Pay attention to the
falling branches since they may bounce in the direction
of the operator after hitting the ground.
► Fig.31
When cutting thick branches, first make a shallow
undercut and then make the finish cut from the top.
► Fig.32
If you try to cut off thick branches from the bottom, the
branch may close in and pinch the saw chain in the cut.
If you try to cut off thick branches from the top without a
shallow undercut, the branch may splinter.

Carrying tool
Before carrying the tool, always remove the battery
cartridges from the tool, then attach the guide bar cover,

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)
