HANDLING THE WHEEL LOADER IN COLD WEATHER
PREPARATION FOR
OPERATION OF THE MACHINE
IN COLD WEATHER
• Change the engine oil to one of low viscosity
suitable for use in cold weather.
• In cold weather, battery power drops, and
electrolyte may freeze if the battery is not
sufficiently charged. To prevent electrolyte from
freezing, be sure to keep the battery charged at
75% capacity or more. It is also recommended to
keep the battery in closed or heated rooms to
facilitate next starting.
If the battery electrolyte level is too low, do not add
distilled water after operating, add distilled water
before starting the next operation while the engine
can be running.
• Add the antifreeze to cooling water in the radiator
and the recovery tank while machine is out of
operation if ambient temperature drops below 0
℃ .
The mixing ratio between water and antifreeze is
determined by the ambient temperature.

IMPORTANT :
• Use a permanent-type antfreeze or long-life
coolant.
• Be sure to drain the cooling water and deposits
completely from the radiator interior before
adding a new mixture of water and antifreeze.
• Antifreeze contains anticorrosive. It is not
necessary to add a cleaner to the coolant.
• Engine coolant capacity is as follows.

Recovery tank 1.1 L
TAKING CARE OF MACHINE
AFTER OPERATION IN COLD
WEATHER
1. After operation in cold weather, be sure to remove
mud or water from the machine body.
2. Then park the machine on concrete or where
ground is dry.
3. Lay the planks or the mats on the ground and park
the machine on them.
If you should park the machine on the ground and
the tires freeze during the night, driving will be
impossible.
4. Wipe the surface of piston rod of the hydraulic
cylinders carefully.
If mud should enter the seal with frozen water, it
may be damaged.
5. Drain the water in the fuel system to prevent
freezing at night.
