VEHICLE RECOVERY AND SPRING BRAKES
Recovery Procedure
1. Review and understand all the
cautions and warnings of this
section, see Vehicle Recovery
Guidelines on page 2-15.
2. Install the recovery hitches, see
Recovery Hitch Installation on
page 2-18.
3. Disconnect the drive axle shafts
and cover the open hubs. This
is necessary because if the
transmission is driven by the
driveshaft (rear wheels on the
ground), no lubricant will reach
the gears and bearings, causing
damage to the transmission.
4. Install the recovery rigging using a
safety chain system, see Recovery
Rigging on page 2-21.
5. Make sure the recovered vehicle's
parking brakes are released.
6. 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. 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.
If you don’t desire to use the
recovered vehicle’s brakes,
ensure that you cage the spring
brakes before attempting to move
the vehicle, see Driver Controlled
Main Differential on page 2-18.
WARNING!
Before towing a vehicle, test your air
brakes to ensure that you have prop-
erly connected and inspected the re-
covery vehicle’s brake system. Fail-
ure to do so could lead to a loss of
vehicle control which may result in an
accident involving death or personal
injury.
7. Follow state/provincial and local
laws that apply to vehicles in tow.
8. Do not tow vehicles at speeds in
excess of 55 mph (90 km/h).
