COLD WEATHER
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, 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 antifreeze to coolant in the radiator and
coolant-recovery tank, if the ambient temperature is
expected to drop as follows.
Ambient temperature below 0 ℃
Mixing ratio of water and antifreeze depends on the
expected ambient temperature.
When
mixing, stir antifreeze 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 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.
• See Checking the coolant level on page 155 for
radiator fill volumes.
• See STARTING THE ENGINE UNDER COLD
CONDITIONS on page 117.
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.
