CHECKING HYDRAULIC SYSTEM
1. Check the oil tank level gauge (Figure 10). Oil level
should be at the middle indication of the gauge or
higher. Fill as required
2. Check the surroundings of the oil tank, hydraulic
pump and motor for oil leakage.
ALWAYS keep hands and fingers away from
pinch points. DO NOT allow anyone to reach in
on dangerous sections of the machine to avoid
any accidents.
DANGER
CHECKING THE V-BELT
1. Check all bolts and screws and make sure all are
securely tightened.
2. Check V-belt for proper tension. The normal slack
should be approximately 1/8 inch (3 to 5 mm) when
the belts are forcibly depressed between the two
sheaves (Figure 11). Insufficient tension causes
weak vibration and machine damage.
CHECKING THE CLUTCH BOX OIL LEVEL
1. Check clutch box for any oil leakage.
2. Remove the level plug and check oil level (Figure 12).
3. Add oil if necessary.
