19
Safe Traveling
The bulldozing blade shall be lifted during traveling. Retract the
bucket working device as shown in above diagram and lift the bucket
by 30~40cm off the ground.
Do not slew during the traveling. If it’s necessary to operate the
bucket working device during traveling, operate at sufficiently low
speed to ensure complete control at all times.
When the machine is traveling in 2nd gear (High speed) and a load
higher than set value is applied, the machine will automatically slow down to 1st gear (Low
speed). If the load is reduced, the machine will accelerate and return to 2nd \ gear (High speed).
Please be noted that the traveling speed varies depending on the load condition (For machine
with automatic traveling gearshift reducer system).
Do not drive the machine on a slope steep enough to cause instability of machine. Please be
noted that, in the actual applications, the performances of machine on a slope will be
deteriorated due to severe working conditions.
Downhill
Avoid driving over obstacles whenever possible. If it’s necessary to
drive over obstacles, keep the bucket operating device near the
ground and travel at low speed. Do not drive over any obstacle that
will incline the machine by 10° or larger.
On rugged roads, drive the machine at low speed and avoid the
sudden startup, stop, and direction change. Otherwise, the working
device may come into contact with the ground to cause unbalance and damage of machine or
destruct the structure in surrounding area.
Precaution for Traveling on Slopes
While traveling on slopes, take caution to prevent the rollover and
gliding of machine. Keep the driver seat facing towards the upslope
direction while climbing up a slope. Keep the driver seat facing towards
the downslope direction during downslope traveling. In both cases, pay
special attention to the ground ahead of the machine during traveling.
While traveling on a slope, lower the bucket to 20~30cm off the ground.
While climbing up a steep slope, extend the bucket working device to
the front position. In event of an emergency, lower the bucket onto the
ground and stop the engine of machine.
While traveling on a slope, drive slowly in 1st gear (Low speed). Reduce the engine speed during
downslope traveling. Do not reverse the machine down a slope.

Special Caution for Operations of Machine on Ice/Snow
While traveling on snowy or icy roads, drive at low
speed and avoid the sudden startup, stop, and
direction change.
In snowy regions, the road curbs and the roadside
objects are buried in the snow to become invisible. In
addition, there is a danger of machine rollover or
collision with covered objects. Therefore, always
operate with caution.
There is a danger of rollover or snow entrapment
while driving the machine into thick snow. Drive with
caution and do not drive over road curbs or entrap in
the snow. For frozen soil surface, the ground
becomes soft when the temperature rises, which
may result in rollover of machine and entrapment of
operator in the machine.
While parking the machine on an unstable ground,
lower the bulldozing blade.
