15. Care and Service in Cold Weather
2-88
To prevent the machine from getting stuck in the morning
due to the mud or water and frozen deposits on the under-
carriage, be sure to observe the following precautions.
• Remove mud or water adhering to the machine. If mud
or water droplets adhering to the hydraulic cylinder rods
get into the seals, the seals could be damaged. So do
this to prevent it.
• Park the machine on solid, dry ground.
If no solid, dry ground is available, lay plates on the
ground and park the machine on the plates to prevent
the frozen tracks from sticking to the ground.
• Drain the water accumulated in the fuel system by turn-
ing on the drain plug to prevent freezing.
• As battery performance is deteriorated in low tempera-
tures, cover the battery or move it to a warm place, and
reinstall it in the machine on the next morning.
If the level of the battery electrolyte is low, add distilled
water before starting operation on the next morning. To
prevent the battery from freezing at night, do not add dis-
tilled water after completing operation.
When the temperature rises, do the following:
• Replace the lube oil and fuel with the specified viscosi-
ties according to Section "21. Fueling, Oiling and Greas-
ing Based on Temperature Range".
• If you have added an AF-PT anti-freeze (for one winter
season only), fully drain the cooling system, flush the in-
side of the cooling system well, and fill the cooling water
tank with tap water.
