Operation Under Unusual Conditions (Cont)
Watch instrument panel closely. If any unusual
readings occur stop vehicle and shut off engine.
Park in shelter when possible. If shelter is not
available, park so vehicle does not face into wind.
Place planks or brush under wheels so vehicle will
not freeze in place.
Fuel filter should be drained before topping off fuel
tank. Keep fuel tank as full as possible during cold
operations. Water forms in empty fuel tank as it
cools. Water in fuel system could freeze and block
All snow and ice should be removed from vehicle as
soon as possible. Snow and ice may slow or stop
movement of critical parts if allowed to pile up.
Special care must be used during operations in
extreme cold environment. In extreme cold, engine
coolant and fluid in windshield washer can freeze.
Batteries can freeze and crack. Oil and grease may
get thick and stiff. Rubber may crack or break easily.
Principles for operating in cold environment apply to extreme cold
environment (para 2-36).
Make sure engine arctic kit has been installed.
Operate engine arctic kit as needed (para 2-31b).
Tire air pressure must be checked properly or serious
injury or death may result.
In areas where temperatures reach -50°F (-46°C) or colder, put about 10
pounds of air above normal in tires for long standby periods and overnight.
If additional air is put in tires for standby periods, lower tire pressure to
normal amounts before driving vehicle (para 3-9).
Before operating crane, perform warm-up as follows:
Start engine (para 2-11a).
While engine is at low idle, fully exercise all functions of crane for at
least 5 minutes.
