GB-12

Air filter (Fig. 3-2)

The air filter must be cleaned from dust and dirt

in order to avoid:

Carburetor malfunctions.

Starting problems.

Engine power reduction.

Unnecessary wear on the engine parts.

Abnormal fuel consumption.

Clean the air filter daily or more often if working

in exceptionally dusty areas.

Cleaning the air filter

Remove the air filter cover and the filter (1). Rinse

it in warm soap suds. Check that the filter is dry

before reassembly. An air filter that has been used

for some time cannot be cleaned completely.

Therefore, it must regularly be replaced with a new

one. A damaged filter must always be replaced.

Fuel filter (Fig. 3-2B)

Drain all fuel from fuel tank and pull fuel filter line

from tank. Pull filter element out of holder

assembly and rinse element in warm water with

detergent.

Rinse thoroughly until all traces of detergent are

eliminated. Squeeze, do not wring, away excess

water and allow element to air dry.

NOTE!

If element is hard due to excessive dirt buildup,

replace it.

5. Maintenance

NOTE!

Standard Idle rpm is 2500~3000 rpm

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

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. 3-1)

WARNING!

The cutting attachment may be spinning

during carburetor adjustments.

WARNING!

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 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 cutting attachment still rotates after idle

speed adjustment, contact HITACHI dealer.
