Carburetor adjustment (Fig. 19)
T-SCREW
Fig. 19
English
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-Screw)
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 your Hitachi dealer.
NOTE
Standard Idle speed is 2,800 – 3,200 min
-1
.
WARNING
When the engine is idling the cutting
attachment must under no circumstances rotate.

Fig. 20
Cleaning the air fi lter
Remove the air fi lter cover and the fi lter (19). 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 lter must always be replaced.
Fuel fi lter (Fig. 21)
Drain all fuel from fuel tank and pull fuel fi lter line from tank. Pull fi lter 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.
Air fi lter (Fig. 20)
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 fi lter daily or more often if working in exceptionally dusty areas.
Fig. 21
Spark plug (Fig. 22)
The spark plug condition is infl uenced by:
An incorrect carburetor setting Wrong fuel mixture (too much oil in the gasoline) A dirty air lter 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, diffi cult to start or runs poorly at idling speed, always check the spark plug fi rst. If the spark plug is dirty,
11
English
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.
0.024˝ (0.6 mm)
Fig. 22
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.
Angle transmission (Fig. 23)
Check angle transmission or angle gear for grease level about every 50 hours of operation by removing the grease fi ller plug on the side of angle transmission. If no grease can be seen on the fl anks of the gears, ll the transmission with quality lithium based multipurpose grease up to 3/4. Do not completely fi ll the transmission.
Daily maintenance
Clean the exterior of the unit. Check that the harness is undamaged. If your unit has blade, check the blade guard for
damage or cracks. Change the guard in case of impacts or cracks.
Check that the cutting attachment is properly
centred, sharp, and without cracks. An off -centre cutting attachment induces heavy vibrations that may damage the unit.
Check that the cutting attachment nut is suffi ciently
tightened.
If your unit has blade, make sure that the blade
transport guard is undamaged and that it can be securely fi tted.
Check that nuts and screws are suffi ciently
tightened.
Weekly maintenance
Check the starter, especially the cord and return
spring.
Clean the exterior of the spark plug. Remove it and check the electrode gap. Adjust it
to 0.024˝ (0.6 mm), or change the spark plug.
Check that the angle gear is fi lled with grease up
to 3/4.
Clean the air fi lter.
Monthly maintenance
Rinse the fuel tank with gasoline. Clean the exterior of the carburetor and the space
around it.
Clean the fan and the space around it.
