Precautions For Traveling On Slopes - Hitachi EX27U Operator's Manual

PRECAUTIONS FOR TRAVELING ON SLOPES

CAUTION: Avoid possible injury from traveling
on slopes. Tipping over or skidding down of the
machine may result. Thoroughly read and under-
stand 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 sus-
pended by the bucket.
1. Never attempt to ascend or descend 25 degrees or
steeper slopes.
Use these gradient values as an operation guide.
They may be reduced if soil condition changes.
2. Be sure to fasten the seat belt. (Cab equipped ma-
chines only)
3. Keep the bucket pointed in the direction of travel, ap-
proximately 200 to 300 mm (8 to 12 in) (A) above the
ground.
4. Traveling across the face of 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.
5. Avoid swinging the upperstructure on slopes. Never
attempt to swing the upperstructure and boom down-
hill. The machine may tip over. If swinging uphill is
unavoidable, carefully operate the upperstructure and
boom at slow speed.
6. If the engine stalls on a slope, immediately lower the
blade to the ground. Return the control levers to neu-
tral. Then, restart the engine.
7. Be sure to thoroughly warm up the machine before
ascending steep slopes. If hydraulic oil has not
warmed up sufficiently, sufficient driving power to as-
cend may not be obtained.
