OPERATION
Correct handling of tool (Fig. 13)
Correct posture
WARNING:
• Always position the tool on your right-hand side
so that the barrier is always in front of your body.
Correct positioning of the tool allows for maximum
control and will reduce the risk of serious personal
injury caused by kickback.
CAUTION:
• If during operation the cutting tool accidentally
impacts a rock or hard object, stop the tool and
inspect for any damage. If the cutting tool is
damaged, replace it immediately. Use of a damaged
cutting tool could result in serious personal injury.
Put the shoulder harness on your left shoulder by putting
your head and right arm through it and keep the tool on
your right side while always keeping the barrier in front
of your body.
Attachment of shoulder harness (Fig. 14)
Adjust the harness length so that the cutting tool is kept
parallel with the ground.
Connect the hanger and the harness.
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.
Adjustment of the hanger position and shoulder
harness (Fig. 15)
Adjust the hanger position as illustrated. (Fig. 16)
To change the hanger position, loosen the bolt on the
hanger. Then move the hanger.
After adjusting the hanger position, tighten the bolt with
the wrench securely.
MAINTENANCE
WARNING:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance on the tool. Failure to switch off
and unplug may result in serious personal injury from
accidental start-up.
NOTICE:
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing the nylon cord (Fig. 17)
WARNING:
• Make sure that the nylon cutting head is secured to
the tool properly before operation. Failure to properly
secure the nylon cutting head may cause it to fly apart

located at the center of the spool between the two
channels provided for the nylon cord. (Fig. 19)
6. Wind both ends firmly along the channels in the
direction indicated by arrow mark on the spool.
