SAFETY MACHINE OPERATION
SAFETY
2-26
q
When traveling up a steep slope, extend the work equipment
to the front to improve the balance, keep the work equipment
approximately 20 to 30 cm above the ground, and travel at
low speed.
q
When traveling downhill, lower the engine speed, keep the
travel lever close to the neutral position, and travel at low
speed.
q
Always travel straight up or down a slope. Traveling at an
angle or across the slope is extremely dangerous.
q
Do not turn on slopes or travel across slopes. Always go
down to a flat place to change the position of the machine,
then travel on to the slope again.
q
Travel on grass, fallen leaves, or wet steel plates with low
speed. Even with slight slopes there is a hazard that the
machine may slip.
OPERATIONS ON SLOPES
q
When working on slopes, there is a hazard that the machine may lose its balance and turn over when the swing
or work equipment are operated. This may lead to serious injury or property damage, so always provide a stable
place when carrying out these operations, and operate carefully.
q
Do not swing the work equipment from the uphill side to the
downhill side when the bucket is loaded. This operation is
dangerous, and may cause the machine to tip over.
q
If the machine has to be used on a slope, pile the soil to
make a platform (A) that will keep the machine as horizontal
as possible.
