12. OPERATION 12.9 PRECAUTIONS FOR OPERATION 12.9.1 PAY ATTENTION TO GAUGES When the red range lights on the power train oil temperature gauge while operating, reduce load and wait for lowering of tem- perature. 12.9.2 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. 12.9.3 PERMISSIBLE WATER DEPTH When operating in water, always keep top surface 1 of the track frame 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. 12.9.4 PRECAUTIONS WHEN TRAVELING UP OR DOWN HILLS Method of using decelerator pedal When stepping on the decelerator pedal while going uphill, climbing ability will be reduced and the machine will stop. Further- more, the engine sometimes will stall. 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. Do not move the joystick to the N 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. 2-61
