Average cruising ranges at Gross Combination Weight Rating (GCWR) with a full tank of fuel will vary

based on conditions (e.g., varying loads, prolonged idle, and climatic conditions). Cruising range is opti-

mally 300 miles (483 km).

(3)

The M915A4 is equipped with an instrument panel mounted speedometer and tachometer which register

truck ground speed and engine speed.

(4)

The M915A4 has the following capabilities and features:

(a) air-activated front and rear non-asbestos cam brakes with a four-channel anti-lock brake system

(ABS) to provide significantly improved handling and braking during emergency stops;

(b) operation in temperatures from -25F (-32C) to +125F (+52C), and to -40F (40C) with arctic kit

installed;

(d) fording capability up to 20 in. (51 cm) deep for 5 minutes without damage or requiring maintenance

before operations can continue;

(e) two-passenger aluminum corrosion-proof cab with a 90 degree tilt-forward hood for service accessi-

bility;

(f) six cylinder, 14 liter, 400 horsepower, in-line turbocharged diesel engine built by Cummins;

(g) Allison HD 4560P four-speed automatic transmission.

When operating in arctic conditions, the M915A4 can be equipped with an arctic heater, mounted under

the cab, above the battery box. This provides heat for the cab and the engine cooling system. The arctic

heater may be operated prior to starting the engine to provide preheating of engine block.
