Then set parking brake switch (2) to “TRAVEL” position to
release the parking brake.
REMARK
If the engine is stopped with the parking brake switch at
“TRAVEL”, the parking brake will be automatically applied
even though the parking brake switch is at “TRAVEL”. In
this case, operate the switch to “PARKING”, and then
move it back to “TRAVEL” to release the parking brake.

Set gear shift lever (4) to a desired position.
NOTICE
• Always place the gear shift lever securely in posi-

placed securely in position, the shift lever position
pilot lamp on the machine monitor may start flash-
ing and the centralized warning lamp may light up,
and the alarm buzzer may sound.
• Always release the accelerator pedal when moving
the gear shift lever from positions NEUTRAL (N) to
REVERSE (R) or FORWARD (D or F).

Depress accelerator pedal (5) to start the machine.
NOTICE
• If the gear shift lever is shifted to a position other
than NEUTRAL position (N) when the parking
brake has not been released, the centralized warn-
ing lamp will light up and the alarm buzzer will
sound.
• If the gear shift lever is shifted to a position other
than NEUTRAL (N) when the dump lever is in a po-
sition other than “FLOAT” or the dump body is
raised, the centralized warning lamp lights up, the
body float caution lamp lights up in red, and the
alarm buzzer sounds.
• Do not operate the gear shift lever with the accel-
erator pedal depressed.
This will cause a big shock, and will also reduce
the service life of the machine.
