WARNING
An open air line on the recovered vehi-
cle
will cause a leak in the air system
of the recovery vehicle if both vehicles’
brake systems are connected. This
could cause a loss of system air, which
can cause the service brakes not to
function, resulting in the sudden appli-
cation of the spring brakes causing
wheel lock-up, loss of control, or over-
take by following vehicles. You could
be in an accident involving personal in-
jury or death. Ensure that any air line
that has been removed from a driver-
controlled main differential lock is firm-
ly capped to prevent loss of air pres-
sure from the recovery vehicle if it is
supplying air pressure.
CAUTION
A recovered vehicle will have no op-
erational
brake system. Additionally,
the rear axle spring brakes will proba-
bly be applied.
• If you desire to use the recovered
vehicle’
s brakes, ensure that the
vehicle's air system is connected to
that of the recovery vehicle. Also
ensure that any air line that has
been removed from a driver-
controlled main differential lock is
firmly capped to prevent loss of air
pressure from the recovery vehicle.
• If you don’t want to use the
recovered vehicle’s brakes, ensure
that you cage the spring brakes
before attempting to move the
vehicle.
1. Remove the air line and firmly cap
the air line from the vehicle. (2)
2.
Remove the caging bolt from its
storage hole. (1)
3. Screw the caging bolt into the air
line hole. (2)
4. When fully engaged, a 0.25-0.5 in.
(6.35-12.7 mm) space will remain
between the air cylinder and the
bolt head. This action will lock the
differential by pushing a piston into
a “lock” position.
