An improperly positioned load can overload the liftgate and result in sudden liftgate failure and/

or increased risks to personnel of being hit or crushed by loads. IMPROPERLY POSITIONED 

LOADS MAY RESULT IN SERIOUS PERSONAL INJURY AND/OR DEATH. Always position 

loads properly on the liftgate platform.  Follow information below on how to position loads 

properly.

POSITION LOADS PROPERLY ON PLATFORM

  NEVER off-center the load on the platform, from side to side or away from truck as this 

may overload the liftgate. The center of weight of the load should NEVER be placed beyond 

the center of the platform load surface, away from truck. Loads should be placed close to the 

platform edge nearest truck. If a load is not uniformly distributed, then the heaviest portion 

should be closest to the edge of the platform nearest the truck. NEVER allow any part of the 

load to extend beyond the edges of the platform’s flat load surface. NEVER allow any part of 

the load to extend over or on, the tapered ramp portion of the platform unless the platform is 

lowered completely to the ground and the ramp is supported by the ground.

!

WARNING

FIG. 1

DO NOT OVERHEAT THE HYDRAULIC PUMP

  Exceeding the duty cycle of the hydraulic pump, can overheat many components, 

including the gear pump, the hydraulic motor, the motor start solenoid, valve coils, etc., and 

significantly shorten the expected life of these components.  In extreme cases, immediate 

damage to the pump or related components may occur. Refer to the Thermal data below.

THERMAL DATA: To avoid overheating the motor do not operate this unit for more than 5 

cycles/ 10 minutes with the maximum load. The motor then must be allowed to completely 

cool down to ambient temperature before cycling the lift again. This unit also has a 10% duty 

cycle, which means the liftgate can be cycled no more than 2 cycles/10 minutes constantly 

with the maximum load.
