Always unload or retract the tag axle

drive axle jacking points to prevent damage to
suspension components.
Jacking the Tag Axle
TAG AXLE
18086
Warning:
The jacking points on the tag axle
must be used for raising the tag axle only.
Towing
Two tow eyes are provided under front bumper.
Towing should be done from these points only by
means of a solid link tow bar and a safety chain.
This recommended method prevents damaging
the vehicle. If required, connect an auxiliary air
supply to the vehicle to release the vehicle
brakes. The engine cannot be started by pushing
or towing the vehicle.
Note:
For more complete information on towing,
refer to
Maintenance Manual
, section 18:
Body
,
under heading
Towing the Vehicle
.
Warning:
Never allow passengers to ride in a
towed vehicle for any reason whatsoever.
Caution:
Internal lubrication of the transmission
is inadequate when vehicle is towed. Remove
the axle shafts (refer to the
Maintenance Manual
for correct procedure) before towing to avoid
possibility of damaging transmission.
Note:
When the axle shafts are reinstalled, en-
sure that the nuts are tightened to the appropri-
ate torques and the axle shafts are properly in-
stalled. Refer to the
Maintenance Manual
for
torque values.
Retractable Tag Axle
Operation of the tag axle is controlled by a valve
located on the L.H. side control panel. The valve
can be flipped to either one of the two positions,
wheels up
or
wheels down
. Axle will automati-
cally be raised or lowered by air pressure ac-
cording to valve position (see page 2-4).
Tag axle service brakes operate only when axle
is down. Never lower tag axle while vehicle is
moving. When tag axle is up, the corresponding
indicator light will illuminate, and a beep will
sound to remind you that axle is up. Tag axle can
be raised in tight maneuvering areas as in park-
ing lots or to help in turning a short corner, thus
shortening the wheelbase and allowing tighter
turning. Raising tag axle transfers extra weight
and additional traction to the drive wheels on a
slippery surface.
Caution:
Always raise tag axle before lifting
vehicle to prevent damage to suspension com-
ponents.
After either of the above uses, vehicle must be
stopped, then tag axle must be lowered before
resuming normal driving.
