5/2020 CC1908S-1 6-103
[3] Battery
WARNING
• The battery produces combustible gas and
can be explosive. Keep naked flames away
from the battery.
• The battery fluid is a hazardous substance.
Keep it away from your eyes and skin.
Should it come into the contact with eyes or
skin, wash the affected area with plenty of
water and seek medical attention
immediately.
• If the battery fluid is frozen, do not recharge
the battery or start the engine using another
power source. Otherwise, there is a risk of
explosion.
• As battery fluid is toxic, do not drain it into a
drain or pour it onto the ground.
The battery performance decreases at low
temperature.
The battery fluid may freeze in cold conditions if
the battery charge is low. Keep it charged as close
to 100 % as possible and try to keep it warm for
starting the next morning.

Measure the charge rate using a charge
meter.
[4] Precautions after completing operations
Observe the following to prevent the machine
from malfunction the next morning because of
deposits such as dirt, water, or other materials
around the frozen tracks:
• Remove dirt and water from the machine.
• Keep the hydraulic cylinder rod surfaces
especially clean to prevent seals from being
damaged by dirt entering together with water
droplets.
• Park the machine on firm dry ground.
If no such location is available to park, place
boards on the ground to park the machine on.
This prevents the ground around the tracks of
the machine from freezing and allows the
machine to start moving quickly the next
morning.
• Open the drain valve on the fuel tank to drain
the water in the fuel system and prevent the
water from freezing.
• Fill up the fuel tank to full. Doing so prevents
water droplets from forming inside the tank due
to temperature changes.
• The battery performance decreases noticeably
at low temperature.
Cover the battery or remove the battery from
the machine and keep it in a warm place to be
installed the next morning.
[5] After cold weather has passed
When the season changes and the weather starts
to get warmer, take the following actions:
• Replace the lubricating oil in the various parts
with oil of the specified viscosity, referring to
"6.5.1 USE OF FUEL AND LUBRICATING OIL
DEPENDING ON TEMPERATURE" on P. 6-11.
