VEHICLE RECOVERY AND SPRING BRAKES
Recovery Hitch Installation
Use the following procedure to install
the Vehicle Recovery Hitches. See
Recovery Hitch Assembly illustration
for part identification.
1. Check square sockets behind
lower bumper for obstructions,
clear if necessary.
2. With lock pins removed, insert
hitches through bumper and into
the square hitch socket.
3. Align the hole in the tow hitch with
the square hitch socket hole.
4. Insert the lock pin into the square
hitch socket hole and through
the hole in the tow hitch until the
lock tab is within the square hitch
socket.
5. Rotate the lock pin 90 degrees to
secure the pin in place.
6. Remove the hitches and store all
parts after recovering the vehicle.
Driver Controlled Main Differential
Follow these steps to lock a
driver-controlled main differential.
WARNING!
An open air line on the recovered
vehicle 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, re-
sulting in the sudden application of
the spring brakes causing wheel
lock-up, loss of control, or overtake
by following vehicles.
You could
be in an accident involving death
or personal injury. 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 it is supplying air pressure.
