Towing Recommendations - PREVOST H3-45 2023 Operator's Manual

76 - Controls and Instruments -
1 (First Range)
Select this range when pulling through mud and
snow, when speed control is needed for driving
up or down steep grades or when maneuvering in
tight spaces. This range also provides maximum
driving torque and engine braking power or
retarder braking effect. In the lower ranges (1, 2,
3 and 4), the transmission will not upshift above
the highest gear selected
overspeed is detected.
2 (Second Range)
Select this range when operating in heavy and
congested traffic. The transmission will start in
first and automatically upshift to second. When
slowing, the transmission will automatically
downshift to first range. Low ranges provide
progressively greater engine and retarder braking
power (the lower the range, the greater the
engine and retarder braking effect).
3, 4 (Third And Fourth Ranges)
Select these ranges when driving on moderate
grades or when load and traffic conditions limit
speed.
WARNING
Service brake should not be used to control the
speed of the vehicle on long, steep descents.
Instead, lower transmission ranges should be
used in conjunction with the output retarder.
Refer to AUXILIARY BRAKE CONTROL
STALKS in this sectionfor details regarding
both systems. This procedure keeps service
brake cool and ready for emergency stopping.
CAUTION
When descending in lower ranges, care must
be taken that engine speed does not exceed
2,450 rpm.

TOWING RECOMMENDATIONS

CAUTION
When towing the vehicle, the transmission
output shaft must not be allowed to spin or turn.
If the vehicle is towed with the drive wheels still
in contact with the road surface, the vehicle
axle shafts or driveline must be removed or
disconnected. Do not attempt to push or pull-
start the vehicle.
Failure to disconnect the driveshaft, remove the
drive axle shafts or lift the drive wheels off the
ground before towing will cause serious
damage to transmission.
Non- compliance with the above requirements
will void warranty.
CAUTION
Make sure axle shafts or driveshaft are installed
correctly after towing. Tighten axle shaft and
driveshaft nuts to the correct torque settings.
Do not invert shafts.
