412 MAINTENANCE AND LUBRICATION
This method is preferred when the proper equipment is not available to perform the wheel
lift method or the axle fork method, and is necessary for wreckers not equipped with
an under lift system.
Spring Eye and Hanger Lift Method
This method is permitted for under lift equipped units. Caution must be taken not to damage
the leaf spring (see illustration for proper installation).
•
Inspect the ends of the spring cradles for burrs or sharp edges that could damage spring.
•
When securing the vehicle to the boom, use (preferably) nylon safety straps. Chains
have a tendency to bind and may cause damage to the axle.
Note: When lifting a vehicle with the under lift boom (see illustration) care must be taken
not to damage the engine oil pan. It may be necessary to remove front fairing. If necessary,
place a block of wood between the top of the boom and the bottom of the axle.
