VEHICLE OPERATION
IMPORTANT
Vehicles with manual transmissions should
not be towed even short distances without
suspending rear wheels or removing the
propeller shaft.
TOWING VEHICLE WITH REAR WHEELS SUSPENDED
Whenever possible, it is preferable to tow a disabled
vehicle from the rear by raising the rear of the chassis and
towing it backwards which will eliminate the preparations
required when the rear drive wheels are on the ground. When
towing a vehicle with rear of the chassis suspended, the front
wheels must be locked in the straight ahead position.
Vehicles with manual shift must have at least one (1)
pint of transmission lubricant drained from the case. This will
prevent transmission lubricant from entering the clutch
housing and lubricant saturating the clutch discs. Make sure
that the transmission lubricant is replaced before the vehicle
is put back into service.
Towing the vehicle with the front wheels on the ground
also eliminates possible damage to the front bumper.
IMPORTANT
Full floating axles are axles where the axle
shafts may be removed without disturbing the
wheel and hub assemblies. On chassis with
full floating axles, remove the axle shafts from
all axles to be in contact with the road surface
during the towing operation. The wheel hub
ends must be covered to prevent loss of axle
lubricant and entrance of contaminants.
If axle shafts are not removed, removal of rear
propellar shafts will be required.
In the event the chassis is equipped with
tandem axle and the vehicle is to be towed
from the front, the forward rear axle may be
raised to clear the road surface and secured
to the frame by chains or "U" bolts, allowing
only rear axle to contact road surface and axle
shafts removed from rear axle assembly, Use
extreme care in securing the chains or "U"
bolts to avoid possible damage of brake lines,
hoses or other components.
TRANSFER CASE
This control "ENGAGES" or "DISENGAGES" the front
axle and selects the "HIGH" or "LOW" speed range of the
transfer case.
CAUTION
When parking your 4 x 4 vehicle the following
procedures must be followed:
Failure to follow these procedures, could
result in an unattended vehicle moving, thus
resulting
in
personal
injury
or
property
damage.
AUTOMATIC TRANSMISSION
1.
Transfer case must be in gear.
2.
Transmission must be in "PARK"
MANUAL TRANSMISSION
1.
Transfer case must be in gear.
2.
Transmission must be in gear.
It is also recommended the parking brake be "Set" at
this time.
SHIFTING (Transfer Case)
The transfer case transmits power to the front driving
axle for operation over rough terrain, steep grades or slippery
surfaces (i.e;, mud, gravel, snow) where improved traction is
required.
Low gear of the transfer case (if so equipped) should
be engaged only when the vehicle is stopped or moving
forward slowly. Low gear is intended for off-highway use only,
where additional gear reduction is occasionally required to pull
heavy loads.
IMPORTANT
The vehicle must not be operated with the
transfer case in low gear on dry, flat, hard
surface
roads.
Operating
under
these
conditions may damage the power train.
