. OPERATION OPERATION If the braking capacity limit is exceeded, a forced cooling system for the brakes is needed, so please consult your Komatsu distributor. 3 - 134 PRECAUTIONS WHEN DRIVING MAC HINE When the machin e travels at high spe ed for a long dista nce, the tire s become extremely hot. This causes early w ear of the tires and s hould be avoided as much as possibl e. If the machine must be d riven for a long distance, take the following precaut ions. ulations related to this machine, and drive carefully. the machine, carry out the checks before starting. ble tire pressure, travel speed, or tire type differ according to the condition of the travel surface.
omatsu distributor or tire dealer for information. Follow the reg ulations related to th is machine, and drive carefu Before driving the machine, carry out the checks b efore starting The most suita ble tire pressure, tr avel speed, or tir e type differ according to th e conditio n of t Contact your K omatsu distributor or tire dealer for i nformation.

Check the oil l evel and coolant lev el also. remely cold areas, do as follows. When stoppin g the machine in ext remely cold area s, do as follows. To prevent the radiator water temp erature from risin g suddenly, do not suddenl y stop the engine. Gradually cool the radiator wa ter down before sto pping the engine Always travel with the bucket emp Never put "cal cium chloride" or "dr y ballast" in the t ires when tr aveling ravel surface.
PRECAUTIONS REGARDING BRAKE FUNCTIO N When traveling lo ng distances contin uously downhill, the frequenc y of using the brake may increas e. As a result, depending on th e weight of the ma chine and the grade of the slope, the machine's braking capacity may be eat. f the values for this machine. the machine' aking capacity exceeded and th e brakes may overh The table below shows a guideline o f the values for th is machine.
