DANGER: Ventilate the area with fresh air when
carrying out warm-up operation indoor. Failure to do
so may cause asphyxiation from exhaust gas, resulting
in death or severe injury.
7. After preheating, start and warm up the engine.
8. After warming up the engine, warm up the loading
hydraulics. Slowly operate the control levers to move
the cylinders full stroke several times. Do not force
cylinders to go to the end of their stroke.
9. Road surfaces covered with snow, especially when snow
has been compacted, will be frozen. Use tire chains on
all four wheels.
10. Take anti-freeze measures after completing operation.
 Spray keyholes with light oil. Cover the keyhole by
sticking a tape on.
 Rubber parts such as wiper blades may freeze. Keep
other parts away from the rubber parts. Warm up cab
prior to use of wipers.
 Remove packed snow from around the axles, articulation
joint and inside the machine with a bar or brush. Be
careful not to damage electrical wiring.
 In case it is impossible to store the machine indoors,
park the machine on a level dry surface and cover the
machine with a large machine cover.
 Keep 80% of tank capacity when storing DEF. The DEF
tank maybe broken if frozen.

NOTE: DEF may start freezing at -10°C (12°F). Freezing does
not affect its performance once thawed.
