OPERATION

USE ENGINE AS BRAKE
When going downhill, move steering, forward-reverse, gear shift lever into low speed to run engine at slow speed
and travel down slope using the engine as a brake.
Do not move the steering, forward-reverse, gear shift lever to the NEUTRAL position.
When traveling down hills of more than 15°, shift down to 1st speed (R1 or F1).
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 3
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, the braking effect will be
reduced, so be careful not to let the fuel level in the fuel tank become too low.
BE CAREFUL OF OIL LEVEL
When operating machine on sloped areas of more than 20°, fill all appropriate components with oil to H level.
PRECAUTIONS WHEN ENGINE STOPS ON SLOPES
If the engine stops while working or traveling on a hill, immediately depress the brake pedal to bring the machine to
a complete stop.
METHOD OF USING BRAKES 3
The following actions cause premature damage to the brakes, so avoid such operations.
q
Using emergency brake at full speed
