OPERATION IN EXTREME COLD - CONTINUED
7.
Machine Operation.
a.
When moving out, be alert that tires may be frozen to ground.
b.
Test brakes and machine controls carefully.
c.
Move all hydraulic controls slowly to warm hydraulic oil. Cycle each control several times. Normal warmup
period in extreme cold is 30 minutes.
d.
Operate under a light load for the first 5 minutes of operation.
e.
Start driving very slowly for about 100 yd (91.4 m). If a problem is noted, notify Unit Maintenance as required.
8.
Parking Machine.
a.
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 wind.
b.
If machine will be parked for a long shutdown period, try to park on high ground. Keep tires out of snow, water,
ice, and mud, if possible.
c.
Clean snow, ice, and mud from engine compartment, hydraulic cylinders, wheels, and work tool as soon as possi-
ble after shutdown.
d.
If machine will be parked for a long period of time, notify Unit Maintenance to prepare machine for storage.
e.
Ensure tires are properly inflated.
ARCTIC COLD WEATHER STARTING AID SYSTEM
0006 00
1.
General.
a.
Machines that operate in extremely cold weather, from -25 F to -40 F (-32 C to -40 C), are factory equipped with
an arctic cold weather starting aid system which includes:
(1) A diesel-fired arctic heater, mounted on left-rear of machine.
(2) Two additional batteries (1,000 CCA each).
WAR N I N G
Use of an arctic heater requires that coolant in system to be heated contains a proper mixture of water and
antifreeze to prevent coolant from freezing or slushing. If coolant freezes or slushes, coolant pump cannot
move coolant, causing blockage in circulating system. Pressure build-up in arctic heater can cause coolant
hose at heater connection to burst or blow off. Injury to personnel or damage to engine could result.
b.
Extreme care should be taken to ensure a proper mixture of water and antifreeze is used in engine cooling system
c.
Engine starting procedures for the arctic operation machine are the same as for the standard machine, except that
arctic heater must first be operated to preheat engine coolant.
