PRECAUTIONS FOR OPERATION
•
In the operation using the fork or grapple, do not attempt to
pick up an object with the tips.
The picked up object can easily slip off. Machine may be
damaged, or personal injury or death may occur.
PRECAUTIONS WHEN OPERATING ON SNOW OR FROZEN SURFACES
•
Snow-covered or frozen surfaces are slippery, so be extremely careful when travelling or operating the ma-
chine, and do not perform abrupt lever operation. Machine may slip even on a slight slope. Be particularly
careful when working on slopes.
•
Frozen road becomes soft when the temperature rises, and the machine may tip over or be not able to es-
cape. Be particularly careful when working on frozen road.
•
It is dangerous that the machine enters deep snow. The machine may tip over or become buried in the
snow. Be careful not to go off the road or to get trapped in a drift of snow.
•
When performing snow removal, the road and objects placed beside the road are buried in the snow and
cannot be seen. Be careful.
PRECAUTIONS WHEN PARKING MACHINE
Unexpected move of the parked machine can cause serious personal injury or death. Always observe the fol-
lowing.
•
Park the machine on a firm, level ground.
•
Select a place where there is no hazard of landslides, fall-
ing rocks, or flooding.
•
Lower the work equipment to the ground.
•
When leaving the machine, set lock lever (1) to LOCK po-
sition (L), then stop the engine.
•
Always close the operator's cab door, and use the key to
lock all the equipment in order to prevent any unauthorized
person from operating the machine. Always remove the
key, take it with you, and keep it in the specified place.
