Reduce the engine speed momentarily when shifting gears.
Do not shift into reverse gears unless the vehicle is completely stopped.
When starting on a hill, depress brake and place transmission in 1 (low)
position, increase engine speed, and release brake.
Do
not hold vehicle on an incline by using the accelerator.
The
transmission will overheat.
Vehicle can throw track if it is backed in UNSPRUNG mode. Do not make
any sharp turns when backing unless suspension is in SPRUNG mode.
If
track is thrown or otherwise rides off the sprockets or roadwheels, stop
the vehicle, but do not walk the track back on! Damage to track and
suspension will result. Follow the maintenance procedures and then
reinstall.
Do not coast down grades. Downshift when going down steep hills. Use
range 2 or 3 for long grades, and range 1 on steep grades.
Observe indicators and warning lights while vehicle is being operated. Do
not allow engine oil pressure to drop below 40 psi (276 kPa), or water
temperature to drop below 150°F (66°C), or go above 190°F (88°C).
Use CB (clutch-brake) steering when driving at low speed in close
quarters.
If engine stops when vehicle is on a grade, immediately stop vehicle and
set parking brake. Move SPRUNG/UNSPRUNG lever to UNSPRUNG
position, and lower blade to secure vehicle. On steep grades, immediately
block tracks on downhill side.
If fording is required, check depth before entering water. Do not attempt to
ford water that is more than 36 in. (91 cm) deep.
When shutting down or parking the vehicle, always raise the hull and
move SPRUNG/UNSPRUNG lever to SPRUNG position so the hull will rest
on the bump stops when hydraulic pressure bleeds down.
Do not attempt to climb onto the vehicle by stepping on the track or any
side/front to get on the vehicle. The only means of entering or exiting is by
using the rear step. When climbing/moving around the vehicle, always
maintain three point contact. Severe injury could occur to personnel if pre-
cautions are not followed.
The vehicle does not have an automatic transmission. The transmission
must be shifted manually.
Refer to TC 21-306, Tracked Combat Vehicle Driver Training, for general
tracked vehicle driving precautions on land or in water.
