SAFETY RULES FOR TRAVELING
q
When traveling on level ground, keep the work equipment at
a height of 40 to 50 cm from the ground.
q
If the work equipment blocks the view and it is difficult to
travel in safety, raise the work equipment to a greater height.
q
When traveling on rough ground, travel at low speed and do
not operate the steering suddenly. There is danger that the
machine may turn over. The work equipment may hit the
ground surface and cause the machine to lose its balance,
or may damage the machine or structures in the area.
q
When traveling on rough ground or steep slopes, if the
machine is equipped with auto-deceleration, always turn the
auto-deceleration switch OFF (cancel).
q
Avoid traveling over obstacles when possible. If the machine
has to travel over an obstacle, keep the work equipment
close to the ground and travel at low speed. Never travel
over obstacles which make the machine tilt strongly to one
side.
q
When traveling or carrying out operations, always keep a
safe distance from people, structures, or other machines to
avoid coming into contact with them.
q
When passing over bridges or structures, check first that the
structure is strong enough to support the weight of the
machine.
q
When operating in tunnels, under bridges, under electric
wires, or other places where the height is limited, operate
slowly and be extremely careful not to let the work equip-
ment hit anything.
TRAVELING ON SLOPES
To prevent the machine from tipping over or slipping to the
side, always do as follows.
q
Keep the work equipment approx. 20 to 30 cm above the
ground. In case of emergency, lower the work equipment to
the ground immediately to help stop the machine.
q
When traveling uphill, set the machine with the operator's
seat on the uphill side; when traveling downhill, set the oper-
ator's seat on the downhill side. Check that the ground
under the machine is safe when traveling.
