4. Starting
��
1) Switch on both stop switches, (M. Parts)
2) Open fuel cock. (Fig. 4)
3) Turn choke lever to CHOKE position. (Fig. 4)
4) Pull throttle lever and push on lock-button, then slowly release the throttle lever. This will lock the
throttle. Meanwhile, the other operator must keep squeezing the other throttle lever fully. (M. Parts)
5) Operator at starter handle side pulls recoil starter briskly taking care to keep the handle in your grasp
and not allowing it to snap back. (Fig. 5)
6) When you hear the engine want to start, return choke lever to RUN position (open). Then pull the
recoil starter briskly again. (Fig. 4)
NOTE: If engine does not start, repeat procedures from 3 to 6.
7) After starting the engine, pull the throttle lever to release lock button.
Then, allow the engine about 2-3 minutes to warm up before subjecting it to any load.
NOTE: To accelerate the engine both throttle levers must be pulled at the same time. As soon as one
operator releases throttle lever, it decelerates engine. (This is normal condition]
CAUTION: It is not recommended that the cable adjuster be touched as it is factory adjusted.
5. Carburetor adjustment (Fig. 6)
WARNING!
Never start the engine without the complete clutch cover. 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 filter 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 bit still rotates after idle speed adjustment, contact HITACHI dealer.
WARNING!
When the engine is idling the cutting attachment must under no circumstances rotate.
NOTE!
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 pre set 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
6. Dritling
1) Both operators must hold the handle firmly with both hands and stand firmly on solid ground so that
you may not be swung by the unit. (Fig. 7)
2) Locate the edge of auger right on the spot to dig and then drive the auger at full throttle for digging.
This is an easy job thanks to the built-in centrifugal clutch. (Fig. 7)
3) Raise auger slightly after every few inches of digging to relieve pressure and clean out the hole.
4) The clutch is made to slip when the auger is overloaded. When this happens, raise the auger slightly
to ease load.
5) When abnormal vibration or noise is generated, stop the engine and inspect the unit.
