C AU T I O N
DO NOT attempt to break tracks loose under engine power. DO NOT move machine with
large frozen lumps of material in tracks. Failure to follow this caution may result in damage
to equipment.
1. If tracks are frozen to ground, notify Field Maintenance.
2. Move machine approximately 100 yards (91 m) in both forward and reverse directions to exercise transmission
and powertrain.
3. Test brakes and vehicle controls carefully.
4. Slowly exercise ground engaging tools to warm hydraulic oil. Cycle each control several times.
5. Operate machine under light loads until machine is sufficiently warmed up (warm air blows from heater vents).
6. Frequently monitor alert indicators and gauges. Take appropriate action if a problem is noted, and if neces-
sary, notify Field Maintenance.
Parking Machine
0006
1. Clean snow, ice, and mud from machine as soon as possible after shutdown.
2. When possible, park in sheltered area, or if shelter is not available, park machine so radiator is not facing the
wind.
3. If shelter is not available, park machine on dry, high ground, and place planks or dunnage under tracks and
ground engaging tools to make a raised and relatively dry platform.
4. Perform all After PMCS procedures (WP 0012).
5. If machine is to be parked for long periods of time, prepare machine for long-term storage (WP 0001).

General
0006
Extreme heat causes problems that you as an operator must be aware of, such as:
1. Fuel expands. Do not fill tanks more than 80 percent full to allow for expansion.
2. Be alert for the possibility of overheating.
3. It is important to maintain engine speed to circulate engine coolant to help engine cooling.
4. Air filter elements will require checking more frequently. They will require cleaning or replacement if air filter
restriction indicator illuminates on the monitor system.
Checks
0006
1. Perform all Before PMCS procedures (WP 0012).
2. Lubricate in accordance with LO 5-2410-241-13.
