SNOW PLOWING CONTINUED
Use of Moldboard
0007
C AU T I O N
Tip moldboard forward to prevent cutting into road surface and causing damage to
equipment.
1. Tip moldboard forward to prevent damage to road surface and machine. This allows the cutting edge to ride
over road surface, instead of cutting into it, which could cause damage to machine and the road surface.
2. When plowing over asphalt or frozen ground, use blade float to allow moldboard to move freely over uneven
surfaces, and prevent road damage.
Use of All Wheel Drive (AWD)
0007
All wheel drive provides additional steering and traction control, and reduces the need for tire chains.
END OF TASK
EXTREME HEAT
0007
General
0007
Extreme heat causes problems that an operator must be aware of, such as:
0007
1. Fuel expands. Do not fill tanks more than 80% 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 ENGINE
SYSTEM indicator illuminates on the monitor system.
Checks
0007
1. Perform all Before PMCS checks and services (WP 0013).
2. Lubricate in accordance with LO 5-3805-293-13.
Machine Operation
0007
1. During very hot weather operation, avoiding continuous high engine RPM will help prevent machine from
overheating. Alter operating procedures accordingly.
2. Check coolant level in coolant tank at frequent intervals throughout any single work shift (WP 0013).
3. Keep radiator and grille free of bugs, dust, dirt, mud, and other foreign matter. Clean frequently if necessary
4. Monitor engine coolant temperature gauge. Red range on gauge indicates coolant temperature is above 225F
(107C). If coolant temperature indicator comes on, machine may be operated at three-fourths workload until
indicator goes off. If indicator remains on longer than ten minutes, shut down machine and notify Field Level
Maintenance.
5. Monitor hydraulic oil temperature gauge. Red range on gauge indicates coolant temperature is above 199F
(93C). If hydraulic oil temperature indicator comes on, machine may be operated at three-fourths workload
until indicator goes off. If indicator remains on longer than ten minutes, shut down machine and notify Field
Level Maintenance.
6. Refer to FM 90-3 for additional extreme heat operation information.
