Operation

WARNING:
• If the cutting tool moves at idle, adjust the idle speed of the

Adjusting the hanger position and shoulder
harness
750 mm
(29-1/2")
WARNING:
Do not use the tool if you cannot adjust the hanger position
and shoulder harness length within the range as illustrated.
Using the tool with improper weight balance may bring the cutting
tool upward and result in personal injury.
When replacing an accessory with another, the weight balance
of the equipment may change. In such case, adjust the hanger
position and shoulder harness length as follows.
To change the hanger position, loosen the fixing screw on the
hanger and then move the hanger (A).
Adjust the hanger position and shoulder harness length so that:
• the hanger positions 750 mm (29-1/2") or higher from the ground,
• the cutting tool positions 100 mm (3-15/16") to 300 mm (11-3/4")
high from the ground and
• the unguarded part of cutting tool is horizontally 750 mm (29-1/2")
or farther away from the hanger.
After adjusting the hanger position, tighten the screw with a wrench
or screwdriver (depending on the power unit) securely.
Using a nylon cutting head
During operation, use the tip of the nylon cutting cord for cut.
As the nylon cutting cord is worn and shortened with the cutting
operation, the operator needs to feed it manually.
To feed the nylon cutting cord, tap the nylon cutting head on the
ground while it rotates around 6,000 min
NOTE:
• If the nylon cutting cord does not feed out, rewind it. Refer to the
chapter "Inspection and maintenance."
