Loading instructions: 

The capacity of this PMPS-series lifter is 4,000 lb. 

Every unit is labeled with this information (see label 287 
on p. 20). DO NOT attempt to lift loads that exceed the 
capacity! Personal injury or permanent damage to the 
lifter might occur.  

 

When loading the PMPS, always follow these 

guidelines: 

1.  The load should firmly contact the heels of the forks 
2.  DO NOT apply a load to the tips of the forks 
3.  Center the load on the forks 
4.  Only transport loads in the lowered position 
5.  Apply the floor lock 

and

 both caster brakes (only 

one caster shown in diagram at right) whenever 
the lifter is not in use. They should also be applied 
anytime a load is being elevated. To apply the 
floor lock, press down on the lock lever. Apply the 
caster brakes by pressing down the brake lever 
until the brake firmly contacts the top of the wheel.
