Safety
Do not carry out deep digging under the front of the machine.
The ground under the machine may collapse and cause the
machine to fall.
Working heavy loads over loose, soft ground or uneven, broken
terrain can cause dangerous side load conditions and possible
tipover and injury. Travel without a load or a balanced load may
also be hazardous.
Never relay on lift jacks or other inadequate supports when work
is being done. Block tracks fore and aft to prevent any
movement.
When using the machine, to prevent accidents caused by
damage to the work equipment and overturning because of an
excessive load, do not use the machine in excess of its ability (in
terms of the maximum load and stability determined by the
structure of the machine).
When working at the edge of an excavation or on a road
shoulder, the machine could tip over, possibly resulting in
serious injury or death. Investigate the configuration and ground
conditions of the work site beforehand to prevent the machine
from falling and to prevent the ground, stockpiles, or banks from
collapsing.
Precautions for Operation
Be careful not to go close to the edge of a cliff by mistake.
Use the machine only for its main purpose. Using it for other
purposes will cause failures.
To ensure an ample view, do as follows:
• When working in dark areas, attach working lights
and front lights to the machine. If necessary, set up
lighting at the work site.
• Stop operations when the visibility is poor, such as in
fog, mist, snow, and rain. Wait for the visibility to
improve to a level which causes no problems for the
operation.
To avoid hitting the work equipment, always do the following;
• When working in tunnels, on bridges, under electric
wires, or when parking the machine or carrying out
other operations in places with limited height, be
extremely careful not to hit the bucket or other parts.
• To prevent collisions, operate the machine at a safe
speed when working in confined spaces, indoors, or
in crowded areas.
• Do not pass the bucket over the heads of workers or
over the operator's compartment of dump truck.
