OPERATING THE MACHINE
5-21
Loading
IMPORTANT:

Always maintain a clean surface for machine
operation.
Cleaning of materials such as soil and stones spilled
on the work surface will reduce wear and/or damage
on tires.

When carrying loads in the bucket, pay attention to
the road surface conditions. Operate the machine at
such speed so that the load will not spill out of the
bucket, while positioning the bucket at the driving
position.

Refrain from banging bucket against the bucket
stopper as much as possible when removing stuck
material, like clay, from the bucket. This may result
in damage to the front attachment.
Remove material stuck to the bucket with water
under pressure.
Loading is dumping the handling material onto a truck or into
a hopper.
Loading work is performed in either the load and carrying
method or loader and dump truck method. Select either
method depending on the work site conditions while taking
the cost and safety into account.
Load and Carrying Method
d
WARNING:

Be sure to provide a tire stopper (1) in front of the
hopper.

Before raising the lift arm, slightly tilt the bucket
back and forth to stabilize the load in the bucket to
avoid injury or damage to the machine from falling
of loose material.
Avoid raising the lift arm on a slope.

When approaching a hopper with the lift arm raised
never steer the loader. Slowly move the machine.
Never rapidly operate the machine to prevent roll
over.
A wheel loader performs work process of loading, carrying,
and dumping in sequence. Generally, when the carrying
distance is 30 to 100 m (33 to 109 yd), this method is
employed.
Make an upgrade slope of approx. 3° around a hopper
when dumping into the hopper. Be sure to provide a level
area 10 m (33 ft) apart from the hopper and tire stopper (1)
at the hopper edge. Reduction in travel speed will assist
operator's braking operation effort.
