OPERATION IN COLD WEATHER

OPERATION IN COLD WEATHER
PREPARATION FOR WORK IN
COLD WEATHER
• Replace engine oil and hydraulic oil with those of
viscosities suitable for cold weather.
• In cold weather, battery power drops, and the
battery fluid may freeze if the battery is not
sufficiently charged. To prevent the battery fluid
from freezing, be sure to keep the battery charged
at least 75% or more of its capacity after operation.
So that the machine starts easily next time, it is
recommended to keep the battery stored in closed
or heated rooms. If the battery fluid level is too low,
do not add after operation, but add with the engine
running before the next operation.
• Add antifreeze to coolant in the radiator and
recovery tank, if the ambient temperature is
expected to drop below 0 ℃. Mixing ratio of water
and antifreeze depends on the expected ambient
temperature.

IMPORTANT :
• Use permanent antifreeze or long-life coolant.
• Drain the coolant completely and clean the
inside of the radiator, then fill with the water and
antifreeze mixture.
• The antifreeze acts as an anti-corrosive, it is not
necessary to add an additive to the water and
antifreeze mixture.
• Details regarding the radiator fill volumes can
be found in a different section.
(See Checking the coolant level on page 56.)
AFTER WORKING IN COLD
WEATHER
• Clean the machine thoroughly after work and wipe
dry. Otherwise mud and earth on the tracks could
freeze if the temperature drops below the 0 ℃
mark. Operation of the machine is then not
possible.
• Store the machine in a dry place. If not possible,
store on wooden planks or on mats. If the machine
is kept on damp or muddy ground, the tracks could

freeze overnight. Operation of the machine is then
not possible. Furthermore the drive unit may be
damaged.
• The piston rods of the hydraulic cylinders must be
rubbed dry. Otherwise severe damage could occur
if dirty water seeps through the seals.
