2-11. PLACING VEHICLE IN MOTION
This vehicle has been designed to operate safely and efficiently
within the limits specified in this TM. Operation beyond these
limits are prohibited IAW AR 750-1 without written approval from
the Commander, U.S. Army Tank-automotive and Armaments
Command, ATTN: AMSTA-CM-S, Warren, MI 48397-5000.
Communications shelters AN/GRC-122 and AN/GRC-142 RATT
may overload truck by up to 500 lbs (227 kg). Use caution when
driving to avoid damage to equipment or injury to personnel.
The following procedures apply to a vehicle being driven in good
weather on high traction surfaces where little or no wheel slippage
is evident. For operating the vehicle under unusual conditions; i.e.,
unusual terrain, cold weather, ice, snow, dusty or sandy areas, mud
or rain, refer to section IV.
a. Be sure all auxiliary equipment and tools are stored for travel.
Vehicle must be stopped, engine off, and transmission shift lever
placed in N (Neutral), before transfer case can be shifted.
Failure to do this will result in damage to drivetrain.
Do not place transfer case shift lever in H/L (high lock range) or
L (low range) on high traction surfaces where little or no wheel
slippage is evident, particularly when encountering sharp,
continuous turns. Failure to operate the vehicle with transfer case
in H (high range) on high traction surfaces, particularly when
encountering sharp, continuous turns, can damage drivetrain.
b. With transmission shift lever (2) in N (neutral), select H (high range)
transfer case driving gear range using transfer case shift lever (3). This range is
for normal driving in good weather, or on high traction surfaces.
c. Start engine (para. 2-10).
d. Set vehicle light switch (7) (para. 2-13).
Ensure parking brake is released completely before operating the
vehicle. Failure to do so may cause damage to equipment.
To release parking brake, grasp handle firmly and push forward
until handle is seated in its most forward position.
Starting with A1 vehicles, parking brake handles have a safety
release button which must be depressed to release the parking
If covering warning lamp with tape, put a pinhole in the tape in
order to recognize when the light is on.
e. Depress service brake pedal (6). Depress parking brake release button and
release parking brake lever (4). The brake warning lamp assembly (1) should go out.
