OPERATION IN COLD WEATHER CONDITIONS

OPERATION IN 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 32 F (0 C). Mixing
ratio of water and anti-freeze depends on
the expected
However, a 50/50 mix is recommended.

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.

PROCEDURE AFTER WORK

CARRIED OUT

Clean the excavator thoroughly after work and
wipe dry. Otherwise mud and earth on the
crawlers could freeze if the temperature drops
below the 32 F (0 C) mark. 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 hydraulic cylinders piston rods
must be rubbed dry. Otherwise severe damage
could occur if dirty water seeps through the
seals.
