OPERATION
Attaching the shoulder harness
CAUTION:
Always use the shoulder harness
attached to the tool. Before operation, adjust the shoul-
der harness according to the user size to prevent fatigue.
CAUTION:
Before operation, make sure that the shoul-
der harness is properly attached to the hanger on the tool.
CAUTION:
When you use the tool in combination 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 pack-
age and the shoulder harness of the backpack-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 hook of the shoulder harness to the hanger
and put the shoulder harness on. Make sure that the
tool is held securely by the shoulder harness.

Correct handling of the 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 enters the
working area, immediately stop the operation.
CAUTION:
If the cutting tool accidentally
impacts a rock or hard object during operation, stop
the tool and inspect for any damage. If the cutting
tool is damaged, replace it immediately. Use of a dam-
aged cutting tool may result in serious personal injury.
CAUTION:
Remove the blade cover from the
cutter blade when cutting the grass.
Correct positioning and handling allow optimum control
and reduce the risk of injury caused by kickback.
