PRECAUTIONS FOR OPERATION
OPERATE CAREFULLY ON SNOW
q When working on snow or ice-covered surfaces, there is danger of the machine starting to skid even at a very
flat angle. For this reason, drive slowly and avoid sudden starts, turns, or stops.
q When driving on hill flanks covered with snow do not brake abruptly to stop the machine. To stop the machine,
lower the bucket onto the ground.
q The load may vary considerably, depending on the structure of the snow. For this reason, reduce the load and
pay attention that the machine does not start to skid.
q When traveling on snow-covered roads, always fit tire chains.
PARKING MACHINE
q Park the machine on firm, level ground.
q Select a place where there is no hazard of falling rocks or
landslides, or of flooding if the land is low.
q Lower the work equipment completely to the ground.
q When leaving the machine, set safety lock lever (1) to the
LOCK position, pull parking brake lever (2) to the LOCK
position, then stop the engine.
q Lock all points that can be locked and store the key in a
safe place.
q When parking the machine on public roads, ensure that it
does not obstruct traffic. Put up signal lamps and required
warning signs to ensure that passing traffic can clearly see
the machine.
q Adhere to all regulations on parking vehicles and securing
building sites
q If it is necessary to park the machine on a slope, set blocks
under the wheels to prevent the machine from moving.
