Rules for Safe Operation and Maintenance
3
Work with an Observer in
Dangerous
Situations
3-059
When operating the machine where there is poor vis-
ibility, rugged terrain, hills, or limited maneuvering room,
use an observer to help direct the machine 's movement.
The observer should be able to see the machine and its
immediate surroundings, and should use pre-arranged
signals to direct the driver's actions.
Precautions on Slopes
Use the Engine Speed to Help Brake
when
Driving Down a
Slope
3-008
Before driving down a slope, stop the machine temporar-
ily and lower the speed of the engine, and drive down
the slope at a low speed. Let the engine speed help
decelerate the machine. Travel at a low speed on wet
steel plates and in muddy places. The machine may
slip even on a gentle slope, causing a serious accident.
Stopping suddenly when driving down a slope can throw
the operator from the machine or make the machine turn
over, causing serious injury or death.
Observe the Machine’s Load Limit on
a
Slope
15
～
20
Driving on slopes can be dangerous. This is
particularly
true when you are driving with a load. Do not
exceed
500kg, when traveling on slopes of 15° to 20 °. If you
must drive on slopes of more than 20 °, the machine
must not carry a load.
3-008
Do Not Drive Across a Slope to Drive on
the
Slope
3-009
Always travel straight up and down a slope. Never travel
across a slope or along a contour line. Driving across
a steep slope or along a contour line is dangerous and
may cause the machine to tip over causing serious injury
or death.
Never perform turning operation on a slope. If a route
must be changed unavoidably, move the machine to
level ground temporarily before turning.
