Precautions for Traveling on Slopes

d
CAUTION: Avoid possible injury from traveling
on slopes. Tipping over or skidding down of the
machine may result. Thoroughly read and understand
precautions below and be sure to travel at slow speed
on slopes. Never attempt to travel on slopes with the
bucket loaded or any load suspended by the bucket.
 Never attempt to ascend or descend slopes of 25 degrees
and over.
 Be sure to fasten the seat belt.
 Keep the bucket pointed in the direction of travel,
approximately 200 to 300 mm (8 to 12 in) (A) above
the ground. If the machine starts to skid or becomes
unstable, lower the bucket immediately.
 Driving across the face of a slope or steering on a
slope may cause the machine to skid or turnover. If
the direction must be changed, move the machine to
level ground, then, change the direction to ensure safe
operation.
 Avoid swinging the upperstructure on slopes. Never
attempt to swing the upperstructure downhill. The
machine may tip over. If swinging uphill is unavoidable,
carefully operate the upperstructure and the boom at
slow speed.
 If the engine stalls on a slope, immediately lower the
bucket to the ground. Return the control levers to neutral.
Then, restart the engine.
 Be sure to thoroughly warm up the machine before
ascending steep slopes. If hydraulic oil has not warmed
up sufficiently, adequate performance may not be
obtained.
