loop handle. (Fig. 2)
Attach the handle to the drive shaft tube with the angle towards the
engine.
Adjust the location to the most comfortable position before operation.

OPERATING PROCEDURES

Fuel (Fig. 3)
WARNING
The trimmer 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
○ Always use branded 89 octane unleaded gasoline.
○ Use genuine two-cycle oil or use a mix between 25:1 to 50:1,
please consult the oil bottle for the ratio or Hitachi dealer.
○ 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.
○ Always mix fuel and oil in a separate clean container.
Always start by fi ling half the amount of fuel, which is to be used. Then
add the whole amount of oil. Mix (shake) the fuel mixture. Add the
remaining amount of fuel.
Mix (shake) the fuel-mix thoroughly before fi lling the fuel tank.
Fueling
WARNING
○ Always shut off the engine before refueling.
○ Slowly open the fuel tank, when fi lling up with fuel, so that possible
over-pressure disappears.
○ Tighten the fuel cap carefully, after fueling.
○ Always move the trimmer at least 3 m from the fueling area before
starting.
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 (Fig. 4, 5)
CAUTION
Before starting, make sure the cutting attachment does not touch
anything.
1. Set ignition switch (5) to ON position. (Fig. 4)
* Push priming bulb (8) several times so that fuel fl ows through the
bulb or return pipe. (If so equipped) (Fig. 5)
2. With the safety trigger (6) pressed (if so equipped), pull throttle
trigger and push throttle lock (7), then slowly release the throttle
trigger fi rst, then the safety trigger. This will lock the throttle in
starting position.
3. Set choke lever to CLOSED position (9). (Fig. 5)
4. Pull recoil starter briskly, taking care to keep the handle in your
grasp and not allowing it to snap back.
5. When you hear the engine want to start, return choke lever to RUN
position (open). Then pull recoil starter briskly again.
NOTE
If engine does not start, repeat procedures from 2 to 5.
6. After starting engine, pull throttle trigger to release throttle lock.
Then allow the engine about 2–3 minutes to warm up before
subjecting it to any load.
Stopping (Fig. 6)
Decrease engine speed and run at an idle for a few minutes, then turn
off ignition switch (5).

MAINTENANCE

MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION
CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY
NON-ROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 7)
WARNING
○ The cutting attachment may be spinning during carburetor
adjustments.
○ Never start the engine without the complete clutch cover and
tube assembled! Otherwise the clutch can come loose and cause
personal injuries.
In the carburetor, fuel is mixed with air. When the engine is test run at
the factory, the carburetor is basically adjusted. A further adjustment
may be required, according to climate and altitude. The carburetor has
one adjustment possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air fi lter is clean. When the idle speed is correct, the
cutting attachment will not rotate. If adjustment is required, close
(clockwise) the T-screw, with the engine running, until the cutting
attachment starts to rotate. Open (counter-clockwise) the screw until
the cutting attachment stops. You have reached the correct idle speed
when the engine runs smoothly in all positions well below the rpm when
the cutting attachment starts to rotate.
If the cutting attachment still rotates after idle speed adjustment,
contact your Hitachi dealer.
NOTE
○ Standard Idle rpm is 2500–3000 rpm.
○ Some models sold areas with strict exhaust emission regulation
do not have high and low speed carburetor adjustments. Such
adjustments may allow the engine to be operated outside of their
emission compliance limits. For these models, the only carburetor
adjustment is idle speed.
For models that equipped with low and high speed adjustments;
carburetors are preset at the factory. Minor adjustments may optimize
performance based on climate, altitude, etc. Never turn the adjustment
screws in increments greater than 90 degrees, as engine damage can
result from incorrect adjustment, If you are not familiar with type of
adjustment-assistance Hitachi dealer.
WARNING
When the engine is idling the cutting attachment must under no
circumstances rotate.
