PMENT
Mud and water accumulation on the undercarriage can affect normal operation of the machine. After operating the
machine in mud or water, make sure to perform the following actions after daily operation:
•
Remove mud and water from the machine. Mud, dirt, and water can damage the seals. See “Operation on Soft
Ground” on page 4-38.
•
Park the machine on a firm, dry surface.
•
If possible, park the machine on boards, which can prevent the tracks from sinking into soft ground. Normal
operation can fail if the machine becomes stuck.
•
Open the drain valve of the fuel/water separator to drain any water in the fuel system. See “Check and Drain
the Fuel/Water Separator” on page 4-9.
Machine Storage in Cold Weather
1. Clean the machine.
2. Check the engine coolant and engine oil levels, and check for leaks. The machine is normally filled to
withstand a minimum low temperature of -40°F (-40°C). Change the fuel, hydraulic oil, and gear oil with new
fluids that meet the air temperature requirements as necessary.
3. Check the machine for leaks. Check all cylinder rods for scratches and corrosion. Apply grease to exposed
cylinder rods.
4. Remove and charge the battery. When the battery is fully charged, store it indoors.
5. Install the battery and start and run the machine on a monthly basis.
6. Clean the battery terminals as necessary. Apply a coat of dielectric grease to the terminals. Check the specific
gravity of the electrolyte and add distilled water or electrolyte if necessary.
After Cold Season
•
Replace the fuel and engine oil with fuel and oil of the specified viscosity.
•
If permanent ethylene glycol coolant was not used and ethanol coolant is used as an alternative, or if no coolant
was used, drain and flush the cooling system completely, and add new ethylene glycol coolant to the cooling
system.
