OPERATING PROCEDURES
Fuel (Fig. 2)
WARNING
The hedge trimmer is equipped with a two- stroke engine.
Always run the engine on fuel, 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 (10W/30) or waste oil.
○ Always mix fuel and oil in a separate clean container.
Always start by fi lling 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 (Fig. 3)
○ Always shut off the engine before refueling.
○ Slowly open the fuel tank (6), when fi lling up with fuel, so that
possible over-pressure disappears.
○ Tighten the fuel cap carefully, after fueling.
○ Always move the unit 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
CAUTION
Before starting, make sure the cutting attachment does not
touch anything.
1. Set ignition switch (7) to ON position (A). (Fig. 4, 5)
* Push priming bulb (10) several times so that fuel fl ows through
the bulb or return pipe. (If so equipped) (Fig. 6)
2. With the safety lever (8) pressed, pull throttle trigger and push
lock button (9) (If so equipped), then slowly release throttle the
trigger fi rst, then the safety lever. This will lock the throttle in

4. Pull recoil starter briskly, taking care to keep the handle in your
grasp and not allowing it to snap back. (Fig. 8, 9)
5. When you hear the engine attempts to start, return choke lever to
RUN position (open) (C). Then pull recoil starter briskly again.
NOTE
If engine does not start, repeat procedures from 2 to 4.
6. After starting engine, allow the engine about 2-3 minutes to
warm up before subjecting it to any load.
Cutting
When cutting, operate engine at full throttle as this maintains proper
cutter speed. When trimming top of hedge, hold trimmer so blades
are between 15 and 30 degrees from a horizontal position and swing
trimmer in an arc toward edge of hedge to sweep cuttings off . When
trimming sides of hedge, hold blade vertically and swing unit in an
arc.
NOTE
○ Multi-position twist handle (Fig. 10, 11) (except single
blade)
The rear control handle turns 70 degrees to provide comfortable
use while accommodating a variety of cutting angles. The handle
allows for fi ve diff erent locking positions. Before attempting to
adjust rear handle, make sure the machine is at idle or engine is
shut off .
○ The machine will automatically shut off if the throttle lever
is pressed while the handle is NOT secured in one of the fi ve
preset positions. Never attempt to operate the machine unless
the rear handle is properly locked in place.
To rotate the handle; push the lock lever (12) allowing the handle
to turn. When the mark (13) on the rear handle aligns with the
mark (14) on the frame/gear case, push the lock lever back to the
locked position.

MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION

NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 13)
WARNING
○ The cutting attachment may be spinning during carburetor
adjustments.
○ Never start the engine without the complete clutch cover (15).
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 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 Hitachi dealer.
