12. OPERATION 12.9 PRECAUTIONS FOR OPERATION 12.9.1 METHOD OF USING STEERING CLUTCH If the steering clutch one side is used frequently or if many gradual turns are made with steering clutch half-engaged, the steer- ing clutch will wear out in a short time. Design the travel road well and steer the machine properly. 12.9.2 PERMISSIBLE WATER DEPTH When operating in water, always keep the bottom of the carrier roller 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.
12.9.3 PRECAUTIONS WHEN TRAVELING UP OR DOWN HILLS AE080320 Use engine as a 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 or with the inching pedal depressed. 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.
12.9.4 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 traveling on a hill, immedi- ately depress the brake pedal, lower the blade to the ground to stop the machine, then lock the brake pedal with the brake lock lever. Thereafter, move the gear shift lever to the N (neutral) position, lock the lever, then restart the engine. 2-33
