EXPLANATION OF COMPONENTS
GREASE PUMP HOLDER
Open the tool box cover on the left side of the machine, and
you see the grease pump storage place.
When storing the grease pump, pass its nozzle through the
hole at the end until it stops.
FIRE EXTINGUISHER
(if equipped)
A fire extinguisher is prepared at the rear part inside the opera-
tor's cab.
The directions are described on the nameplate affixed to the
fire extinguisher. Just in case, carefully read and understand
them beforehand.
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.
Operate the battery disconnect switch only when the engine is stopped.
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 the fuse, etc.
Do not turn the 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 the information again. For detail, see "CLOCK ADJUSTMENT (3-76)" and
"HANDLE RADIO (3-211)".
The battery disconnect switch is used to cut out the electricity from the battery.
