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. 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.
