OPERATION UNDER COLD WEATHER CONDITIONS

PREPARATION FOR OPERATION IN COLD
WEATHER
1. Replace engine oil and hydraulic oil with those of
viscosities suitable for cold weather.
2. 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. To ease next starting, 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.
3. Add anti-freeze to coolant in the radiator and reserve
tank, if the ambient temperature is expected to drop
below 0 . Mixing ratio of water and anti-freeze
depends on the expected ambient temperature.
A Mixing ratio between water and anti-freeze
Ambient -5 -10
Temperature ( ) (+23) (+14)
Antifreeze % 30 30
Water % 70 70
A Use permanent anti-freeze or long-life coolant.
A Drain the coolant completely and clean the radiator
inside then fill with the water and anti-freeze mixture.
A As the anti-freeze also acts as an anti-corrosive, it is
not necessary to add an additive to the water and anti-
freeze mixture.

"Checking Coolant
CHECKS" in "MAINTENANCE" for radiator fill
volumes.

PROCEDURE AFTER DONE WORK

Clean the excavator thoroughly after work and wipe dry.
Otherwise mud and earth on the crawlers could freeze if
the temperature drops below the 0
Operation of the excavator is then not possible. Store the
excavator in a dry place; if not possible, store on wooden
planks or on mats. If the excavator is kept on damp or
muddy ground, the crawlers could freeze overnight.
Operation of the excavator is then not possible.
Furthermore the reduction gear may be damaged.
Additionally, the piston rods of the hydraulic cylinders
must be rubbed dry. Otherwise severe damage could
occur if dirty water seeps through the seals.
