When you operate the M915A1 truck tractor in extreme cold, keep in mind the pro-
blems characteristic of operation in cold weather, and make sure your truck is ade-
quately prepared and protected for the existing weather conditions. Follow these
guidelines when you operate the M915A1 truck in conditions of extreme cold.
ARCTIC WINTERIZATION KIT
See TB9-2320-283-14 for complete information.
Be careful when you first start your truck. USE YOUR COLD WEATHER STARTING
PROCEDURE (paragraph 2-11), AND GIVE THE ENGINE TIME TO REACH AN
OPERATING TEMPERATURE RANGE OF AT LEAST 140°F to 160°F.
Adjust the amount of winter front coverage over the radiator grille to maintain a
normal coolant operating range of 180° to 200°F.
START DRIVING VERY SLOWLY. Be alert for the possibilities that TIRES MAY
BE FROZEN TO THE GROUND, frozen in the shape of flat spots, or that one or
more BRAKE SHOES MAY BE FROZEN and require preheating (notify Organiza-
tional Maintenance, if necessary).
DRIVE VERY SLOWLY FOR ABOUT 100 YARDS, being careful not to let the engine
stall. By starting out slowly and carefully you will be able to detect any initial pro-
blems caused by the cold weather, and your trucks fluids and components will
have a little extra warmup time.
If you shut down your truck for a short period, PARK IN A SHELTERED AREA OUT
OF THE WIND. If there is no shelter available, park so that truck does not face
into the wind. Install the winter front.
IF YOU PARK YOUR TRUCK FOR A LONG SHUTDOWN PERIOD, TRY TO PARK
ON HIGH GROUND, AND USE PLANKS OR BRUSH TO MAKE A RAISED AND
RELATIVELY DRY SURFACE FOR THE TRUCKS TIRES IN CASE WEATHER CON-
DITIONS WORSEN. KEEP THE TIRES OUT OF SNOW, WATER, ICE, AND MUD,
CLEAN YOUR TRUCK OF SNOW, ICE, AND MUD as soon as possible after
IF YOUR TRUCK WILL BE PARKED FOR A LONG PERIOD OF TIME during cold
weather, have Organizational Maintenance personnel REMOVE BATTERIES AND
STORE THEM IN A WARM PLACE. Fill fuel tank to guard against condensation.
Drain any accumulated water from air reservoirs and fuel filter. Install the winter front.
