OPERATION
Correct handling of tool
WARNING:
Always position the tool on your
right-hand side. Correct positioning of the tool allows
for maximum control and will reduce the risk of seri-
ous personal injury caused by kickback.
WARNING:
Be extremely careful to maintain
control of the tool at all times. Do not allow the
tool to be deflected toward you or anyone in the
work vicinity. Failure to keep control of the tool
could result in serious injury to the bystander and the
operator.
WARNING:
To avoid accident, leave more
than 15m (50 ft) distance between operators when
two or more operators work in one area. Also,
arrange a person to observe the distance between
operators. If someone or an animal enter the
working area, immediately stop the operation.

Attachment of shoulder harness
CAUTION:
Always use the shoulder harness
attached. Before operation, adjust the shoulder
harness according to the user size to prevent
fatigue.
CAUTION:
When you use the tool in combi-
nation of the backpack-type power supply such
as portable power pack, do not use the shoulder
harness included in the tool package, but use the
hanging band recommended by Makita.
If you put on the shoulder harness included in the
tool package and the shoulder harness of the back-
pack-type power supply at the same time, removing
the tool or backpack-type power supply is difficult in
case of an emergency, and it may cause an accident
or injury. For the recommended hanging band, ask
Makita Authorized Service Centers.
Connect the clasp of the shoulder harness to the
hanger part of the housing. Put the shoulder harness
on. Be sure that the buckles are locked completely in
place.
