Machine Operation
0007
1. Move machine approximately 100 yards (91 m) in both forward and reverse directions to exercise transmission
and powertrain.
2. Test brakes and vehicle controls carefully.
3. Slowly exercise ground engaging tools to warm hydraulic oil. Cycle each control several times. Monitor
Messenger until transmission oil temperature reaches 41F (5C) (WP 0005).
4. Operate machine under light loads until machine is sufficiently warmed up (warm air blows from heater vents).
5. Frequently monitor Messenger system, alert indicators, and gauges. Take appropriate action if a problem is
noted, and if necessary, notify Field Level Maintenance.
Parking Machine
0007
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 tires and
ground engaging tools to make a raised and relatively dry platform.
4. Perform all After PMCS checks and services (WP 0013).
END OF TASK
SNOW PLOWING
0007
Snow plowing should be performed as soon after snow falls as possible. Plowing techniques vary greatly
depending on amount of snow and type of plowing required. The information provided here is a limited overview of
snow plowing techniques and procedures.
Operating Speed
0007
Generally, increased road speed is required to ensure snow is pushed off and away from road while retaining
control of machine. Too much speed may cause machine to bounce and cause a choppy road surface.
Use of Tire Chains
0007
1. Install chains either on rear tires only, or on both front and rear tires, when plowing in slippery conditions.
2. Reduce travel speeds with tire chains installed.
3. Use bungee cords to keep chains tight around tire. Check chains often during operation.
4. Avoid excessive tire spin with chains installed to prevent damage to road surface.
5. Avoid driving on hard surface roads with chains installed to prevent chain and tire wear.
