MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 10)
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.
Fig. 10
Idle speed adjustment (T)
Check that the air fi liter is clean. If adjustment is required, turn IDLE speed Adjustment Screw (T) close (clockwise) to increase engine speed, open (counterclockwise) to decrease engine speed. Standard Idle rpm is 2800-3200rpm.
RECOMMENDATION:
CARBURETOR ADJUSTMENT NEEDS THE SKILL OF EXPERIENCED OR WELL TRAINED PEOPLE, IR IS RECOMMENDED TO TAKE THE UNIT TO HITACHI DEALER.
Air filter (Fig. 11)
The air fi ler 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
Remove the air cleaner cover by pushing and pulling back the tab on the top.
Clean the air fi liter daily or more often if working in exceptionally dusty areas.
Fig. 11
Cleaning the air fi Iter
Open the air filter cover and the filter. Rinse it in warm soap suds. Check that the fi liter is dry before reassembly. An air fi liter that has been used for sometime cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged fi liter must always be replaced.
Fuel filter (Fig. 12)
Drain all fuel from fuel tank and pull fuel filter line from tank. Pull fiiter 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.
Fig. 12
NOTE
If element is hard due to excessive dirt buildup, replace it.
Spark plug (Fig. 13)
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 diffi culties. If the engine is low on power, difficulto start or runs poorly at idling speed, always check the spark plug fi rst. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.024^ (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.
Fig. 13
NOTE
In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement.
