Carburetor adjustment (Fig. 26)
      

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 Hitachi Authorized 

Service Centers.

NOTE

Standard Idle rpm is 2500–3000 min-1.

      

WARNING

When the engine is idling the cutting 

attachment must under no circumstances 

rotate.

Air fi lter (Fig. 27)

The air fi lter 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 fi lter

Remove the air filter cover and the filter (21). 

Rinse it in warm soap suds. Check that the fi 

lter is dry before reassembly. An air fi lter 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. 28)

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.

Spark plug (Fig. 29)

The spark plug condition is influenced by:

An incorrect carburetor setting

Wrong fuel mixture (too much oil in the 

gasoline)

A dirty air filter

Hard running conditions (such as cold weather)

These factors cause deposits on the spark plug 

electrodes, which may result in malfunction and 

starting difficulties. If the engine is low on power, 

difficult to start or runs poorly at idling speed, 

always check the spark plug first. If the spark plug 

is dirty, clean it and check the electrode gap. Re-

adjust if necessary. The correct gap is 0.6 mm. 

The spark plug should be replaced after about 

100 operation hours or earlier if the electrodes 

are badly eroded.

Angle transmission (Fig. 30)

Check angle transmission or angle gear for
