OPERATION
A fire extinguisher is provided at the rear part inside the opera-
tor's cab.
The directions are described on the nameplate affixed to the
fire extinguisher. Carefully read and understand them before-
hand for an emergency.
BATTERY DISCONNECT SWITCH
Do not operate the battery disconnect switch while the engine is running.
The large current generated by the alternator may burn the electric parts and cause a fire.
When operating the battery disconnect switch, always stop the engine.
If the battery disconnect switch is turned to OFF position, always remove the switch key.
If someone turns the key to ON position carelessly, this is extremely dangerous.
NOTICE
Keep battery disconnect switch in ON position except the following cases.
When the machine is stored for a long time (more than a month)
When repairing the electrical system
When performing electric welding
When handling the battery
When replacing fuse, etc.
Do not turn battery disconnect switch to OFF position while the system operating lamp is lit. If the
battery disconnect switch is turned OFF while this lamp is lit, the data in the controller may be lost.
If this switch is turned to OFF position, all the electrical system is cut out and the functions of KOM-
TRAX stop. In addition, the time information of the clock and the radio tuning information may be
lost. In this case, set again. For detail, see "CLOCK ADJUSTMENT (3-73)" and "HANDLING RADIO
