OPERATION IN EXTREME COLD CONDITIONS - CONTINUED
CAUTION
Never use a scraper to remove frost or ice from ballistic
glass. Failure to comply may result in damage to outer layer
of ballistic glass.
NOTE
To clear frost and ice from ballistic glass, perform step 3 for
M915P1, M915A1P1, M916P1, M917P1, and M920P1
vehicles.
Clearing frost and ice from ballistic glass requires more time
than standard glass.
It will require more effort in extreme cold to open and close
armor doors, egress window, and access door.
4. On vehicles equipped with Crew Protection Kit, extend vehicle warm-up time and
operate heater and defroster to clear frost or ice from all ballistic glass.
END OF TASK
ARCTIC WINTERIZATION KIT
CAUTION
Do not attempt to use extension cords in conjunction with
the supplied winterization auxiliary power cable unless wire
size is sufficient to carry 40 amps of current. Failure to
comply may result in damage to equipment.
1. When operating in arctic conditions, ensure vehicle is equipped with Arctic
Winterization Kit. All vehicles assigned to arctic regions must be equipped with a
winterization kit for protection of vehicle systems from freeze damage and to
enable engine starting in extreme cold. The kit consists of four separate heaters
which are:
a.
Engine coolant heater (thermostatically controlled)
b.
Transmission heater (immersion type)
c.
Engine oil heater (immersion type - thermostatically controlled)
d.
Battery heater (coil type - thermostatically controlled)
2. The arctic winterization system is powered by use of an external alternating
current (ac) power source. A 25 ft (7.6 m) auxiliary power cable, equipped with
ground wire, is provided with the Arctic Winterization Kit. The auxiliary power
cable is designed to connect to the receptacle located adjacent to the vehicle
battery box and a compatible ac outlet. Each of the four heaters is turned on by a
separate circuit breaker located inside a waterproof circuit breaker box. The
heaters function automatically until the system is turned off. To turn on system:
