2-30. OPERATION IN EXTREME HEAT (CONT).
g.
When adding coolant to the radiator, ensure that the water source is soft. Local desert water sources can have
high mineral deposits that will clog the radiator.
h.
Ensure that the water/antifreeze mix is at least 50:50. This mixture raises the coolant boiling point to help prevent
overheating.
2-31. OPERATION IN EXTREME DUST OR SAND.
The distributor normally operates in dusty or sandy conditions and PMCS instructions are designed to handle these
conditions. However, in desert environments dust and sand are more extreme and certain checks and services must be
made more frequently than normal.
a.
Have the fuel/water separator and fuel filter serviced more frequently.
b.
Cover console panel, instrument panel, hydraulic fluid level indicator, and vehicle lights when parked for extended
periods of time in extremely dusty conditions.
c.
Cover open space in fuel hole when adding fuel to the tank.
2-32. OPERATION IN EXTREME COLD.
The distributor can not be operated during periods when temperatures are below -25 degrees F (-32 degrees C). In
situations when the temperature is between -25 degrees and 32 degrees F (-32 degrees and 0 degrees C), the following
instructions must be observed:
a.
Start Up.
(1)
Remove all snow and ice from the distributor.
(2)
Prepare vehicle for operation in severe cold conditions according to FM 9-207 and FM 21-305.
(3)
Keep fuel tank as full as possible during cold weather operations.
(4)
Start engine (para 2-14) and allow it to warm up to normal operating temperature.
(5)
Slowly raise and lower the spraybar assembly (para 2-22) to warm up the hydraulic system.
b.
Operation.
(1)
Cold Weather:
(a)
Use asphaltic material that can be heated to a high temperature, 200 degrees F (592 degrees C) or
more. Apply material at slow speeds so that chip spreaders can stay right behind spraybar.
(b)
Apply blotting material, such as sand, gravel, or chips, as soon as possible to bituminous material so
as to bond properly.
(2)
High Winds:
NOTE
Use of a windbreaker will prevent bituminous material from becoming airborne.
(a)
Install windbreaker at the spraybar, close to the road surface.
