OPERATION IN EXTREME COLD CONTINUED
Machine Operation

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. Test brakes and vehicle controls carefully.
3. Move all implement controls slowly to warm the hydraulic oil. Cycle each control several times. Normal warm-
up period in extreme cold is 30 minutes.
4. Operate under a light load for the first five minutes of operation.
5. Move machine several yards forward and backward to exercise powertrain. Start by driving very slowly for
about 100 yd (91.4 m).
6. Frequently monitor Messenger system, alert indicators, and gauges. If a problem is found, notify Field
Maintenance as required.
Parking Machine
0006
1. If machine will be parked for a short period, park in a sheltered area out of wind. If shelter is not available, park
machine so that radiator does not face into the wind.
2. If machine will be parked for a long shutdown period, try to park on high ground and use planks or brush to
make a raised and relatively dry surface. Keep tracks out of snow, water, ice, and mud, if possible.
3. Clean snow, ice, and mud from entire machine as soon as possible after shutdown.
4. If machine will be parked for a long period of time, have Field Maintenance prepare machine for storage.

General
0006
1. During very hot weather, altering operating procedures may be necessary to prevent machine from
overheating. Avoid continuous high engine RPM.
2. You must be alert for the possibility of overheating.
3. Keep a close eye on engine coolant and hydraulic oil temperature indicators.
4. If coolant or hydraulic temperature indicators come on, you may operate at 3/4 workload until indicators go out.
5. It is important to maintain engine RPM to help cooling.
6. If indicators stay on after more than 10 minutes of reduced workload, stop the machine and notify Field
Maintenance.
