Adjusting the hanger position and shoulder
harness (Fig. 18)
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 or higher from the ground,
• the cutting tool positions 100 mm to 300 mm high from the
ground and
• the unguarded part of cutting tool is horizontally 750 mm 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."

Inspection and maintenance

WARNING:
• Before inspecting or maintaining the equipment, switch of the
motor and remove the spark plug cap or battery cartridge.
Otherwise the cutting tool or other parts may move and result in
serious injury.
• When inspecting or maintaining the equipment, always put it
down. Assembling or adjusting the equipment in an upright
position may result in serious injury.
• Follow the warnings and precautions in the chapter "Safety
precautions" and the instruction manual of the power unit.
Resharpening the cutting tool
WARNING:
Do not resharpen cutting blades by yourself. Manual resharpening
unbalances a cutting blade and it can cause vibrations and damage
to the equipment.
Ask Makita authorized service center to resharpen and rebalance
blunt cutter blades.
Replacing the nylon cord
WARNING:
For the bump and feed type nylon cutting head, make sure that
the cover of the nylon cutting head is secured to the housing
properly as described below. Failure to properly secure the cover
may cause the nylon cutting head to fly apart resulting in serious
personal injury.
The way to replace the nylon cord varies depending on the cutting
tool type. Replace the nylon cord if the cord is not fed any more.
