CAUTION
○ Before operation, make sure the blade has been properly
installed.
○ If your unit is equipped with protection cover under a
cutting blade, check it for wear or cracks before operation.
If any damage or wear is found, replace it, as it is an article
of consumption.
○ You have to wear gloves when handling the cutting
blade.
Installation of nylon head (Fig. 16)
If your unit has nylon head, follow the installation.
Attach cutter holder (22) to the gear case. Insert an Allen
wrench into the hole in the gear case to attach winding
protector (23) and attach nylon head (24) by turning it
clockwise.
NOTE
Since cutter holder cap is not used here, keep it for next
metal blade use.
WARNING
For HiKOKI heads, use only fl exible, non-metallic line
recommended by the manufacturer. Never use wire or
wire ropes. They can break off and become a dangerous
projectile.
OPERATING PROCEDURES
Fuel (Fig. 17)
WARNING
○ The backpack brush cutter is equipped with a two-stroke
engine. Always run the engine on fuel, which is mixed
with oil.
Provide good ventilation, when fueling or handling fuel.
○ Fuel is highly fl ammable and it is possible to get seriously
injured when inhaling or spilling on your body.
Always pay attention when handling fuel. Always have
good ventilation when handling fuel inside building.
Fuel
○ Always use branded 89 octane unleaded gasoline.
○ Use genuine two-cycle oil or use a mix between 25:1 to
50:1, please consult about the mixture ratio to HiKOKI
Authorized Service Centers.
○ If genuine oil is not available, use an anti-oxidant added
quality oil expressly labeled for air-cooled 2-cycle engine
use (JASO FC GRADE OIL or ISO EGC GRADE). Do not
use BIA or TCW (2-stroke water-cooling type) mixed oil.
○ Never use multi-grade oil (10 W/30) or waste oil.
○ Never mix fuel and oil in machine's fuel tank. Always mix
fuel and oil in a separate clean container.
Always start by fi lling half the amount of gasoline, which is
to be used.
Then add the whole amount of oil. Mix (shake) the fuel
mixture. Add the remaining amount of gasoline.
Mix (shake) the fuel-mix thoroughly before fi lling the fuel
tank.

Do not smoke or bring fl ames or sparks near the fueling
site.
○ Slowly open the fuel tank, when fi lling up with fuel, so
that possible over-pressure disappears.
○ Tighten the fuel tank cap carefully, after fueling.
○ Always move the unit at least 3 m from the fueling area
before starting.
○ Always wash any spilled fuel from clothing immediately
with soap.
○ Be sure to check any fuel leakage after refueling.
○ Before fueling, in order to remove static electricity from
the main body, the fuel container and the operator,
please touch the ground that is slightly damp.
Before fueling, clean the tank cap area carefully, to ensure
that no dirt falls into the tank. Make sure that the fuel is well
mixed by shaking the container, before fueling.
Starting

○ Before starting the tool, ensure that the cutting
attachment is not touching any objects or the ground.
Otherwise, the cutting attachment may unexpectedly
rotate and cause an injury.
○ Ensure that the cutting attachment does not rotate while

according to the instructions in "Idle speed adjustment" in
the "MAINTENANCE" section. If the cutting attachment
still rotates after this adjustment, immediately stop the
engine and cease use, then bring the tool to the nearest
HiKOKI Authorized Service Center.
