PRECAUTIONS FOR OPERATION

PERMISSIBLE WATER DEPTH
When operating in water, always keep the bottom of carrier
roller (1) above the surface of the water. Also, be careful that
the engine cooling fan will not come in contact with water. The
fan can be damaged.
PRECAUTIONS WHEN TRAVELING UP OR DOWN HILLS
USE ENGINE AS BRAKE
When going downhill, shift gear shift lever into low speed to run engine at slow speed and travel down slope using
the engine as a brake.
Never coast down slope with the steering and directional lever in the N (neutral) position.
BRAKING WHEN TRAVELING DOWNHILL
While descending a slope using the engine as a brake, also apply the brakes.
Failure to brake may result in overrunning, causing engine trouble.
PRECAUTIONS ON SLOPES
BE CAREFUL OF FUEL LEVEL
If the fuel level in the fuel tank becomes low when working on slopes, the engine may suck in air because of the
angle of the machine or the swaying of the machine. If this makes the engine stop, so be careful not to let the fuel
level in the fuel tank become too low.
PRECAUTIONS WHEN ENGINE STOPS ON SLOPES
If the engine stops while working or driving on a slope, the brake is applied automatically. Take care since the
machine stops suddenly at this time.
IT IS PROHIBITED TO KEEP THE DOOR OPEN DURING OPERATIONS
(Machine equipped with cab)
Always keep the door closed when traveling or carrying out operations.
If the door is open, there is danger of damage from obstacles or strong vibration.
