Plan Your Operation Procedure
 Before starting operations, thoroughly
check the area for unusual conditions that
could be dangerous.
 Examine the shape of the ground, the
quality of the soil, the jobsite, and determine
the optimum method of operation.
 Make sure the ground is firm and level
before starting engine. When working at dusty
worksites, the ground should be watered.
 When working on public roads, position a
flagman and warning signs, such as “NO
ENTRY” to ensure the safety of passing traffic
and pedestrians.
 In places where there are buried objects,
such as water pipes, gas pipes, or pipes for
high voltage cables, contact the company in
charge to confirm the position of the buried
object, and be careful not to damage the object
during operations.
 When working in water or when crossing
sand banks, first check the condition of ground,
the water depth and flow speed. Be sure not to
exceed the permitted water depth. When
working in water or on swampy ground, do not
let the water come above the bottom of the
axle housing. After finishing the operation,
wash and check all lubricating points.
