3.3 Operation

WA500-6H – VEAM430100

3-117

REMARK

To protect the transmission, immediately after the direction has
been shifted between forward and reverse and immediately after
the speed range has changed, even if the directional selector is
operated, or the gearshift lever is operated, or the kickdown
switch is operated, the direction or speed range may not change
immediately, but this does not indicate any abnormality.

Changing direction

Changingdirection

WARNING

z

When changing direction between FORWARD and
REVERSE, check that the new direction of travel is safe.
There is a blind spot behind the machine, so be particularly
careful when changing direction to travel in reverse.

z

Do not switch between FORWARD and REVERSE when
traveling at high speed.
When switching between FORWARD and REVERSE,
depress the brake to reduce the travel speed sufficiently,
then change the direction of travel. (Max. speed for changing
direction: 12 km/h (7.5 MPH))

There is no need to stop the machine even when switching
between FORWARD and REVERSE.

Place directional lever (1) in the desired position.

Position (a): FORWARD

Position N: NEUTRAL

Position (b): REVERSE

Check that the backup alarm sounds when the directional lever
is set to REVERSE. If the backup alarm does not sound, please
contact your KOMATSU distributor for repairs.

REMARK

If the directional lever is operated slowly or is stopped between
directions, the central warning lamp may light up and the alarm
buzzer may sound. This does not indicate any failure, but please
operate the directional lever so that the shift is completed within
2 seconds.
To protect the transmission, immediately after the direction has
been shifted between forward and reverse and immediately after
the speed range has changed, even if the directional selector is
operated, or the gearshift lever is operated, or the kickdown
switch is operated, the direction or speed range may not change
immediately, but this does not indicate any abnormality.
