Operation of the machine under cold weather
conditions
PREPARATION FOR
OPERA
TION OF THE MACHINE
IN COLD WEATHER
• Replace
the engine oil and hydraulic oil with those
of viscosity suitable for cold weather.
• In cold weather, the 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 80% or more of its capacity after operation
of the machine.
To ease next start of the machine, it is
recommended to keep the battery stored in closed
or heated rooms.
• Add anti-freeze to coolant in the radiator and
recovery tank, if the ambient temperature is
expected to drop as follows.
Ambient temperature below 0 ℃
Mixing ratio of water and anti-freeze depends on
the expected ambient temperature.
When
mixing, stir anti-freeze up well, and then fill it
into the radiator.
Mixing ratio between water and antifreeze
Ambient tem-
perature
℃ -5 -10 -15 -20 -25 -30 -35
Antifreeze % 30 30 30 35 40 45 50
Water % 70 70 70 65 60 55 50
IMPORTANT :
•
Use permanent anti-freeze or long-life coolant.
• Drain the coolant completely and clean the
inside of the radiator, then fill with the water and
anti-freeze mixture.
• The anti-freeze acts as an anti-corrosive, it is
not necessary to add an additive to the water
and antifreeze mixture.
• See Checking the coolant level on page 87 for
radiator fill volumes.
• See Starting the engine under cold conditions
on page 55.
STORING THE MACHINE AFTER
COMPLETION OF WORK IN
COLD WEA
THER
1. Clean the machine thoroughly after work, and wipe
dry.
Otherwise mud and earth on the tracks could freeze
if the ambient temperature drops as follows.
Operation of the machine is then not possible.
Ambient temperature below 0 ℃
2. Store the machine in a dry place. If you can not
store the machine in a dry place, store it 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
reduction gear may be damaged.
3. Additionally, rub the piston rods of the hydraulic
cylinders to dry them.
Otherwise severe damage could occur to the piston
rods of the hydraulic cylinders if dirty water seeps
through the seals.
