water pipes and other mechanical hazards in

view that may be unintentionally contacted and may cause personal harm or property damage.

dangerously close to cutting tools and rotating parts.

dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate 

conditions will reduce personal injuries.

. This enables better control 

of the trailer jack in unexpected situations. 

 

Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and 

gloves away from moving parts

parts.

Dismounting from Vehicle.

Before dismounting, chock the trailer wheels to prevent the trailer from rolling.

1.  With the trailer on the hitch, allowing the Trailer Jack to rotate downwards. Keep fingers 

away from the Swivel Plate area, and feet away from the caster as the Jack rotates 

downward.

position. 

3.  Rotate the Crank Handle counterclockwise to lower the Caster Wheel Assembly to the

connections and all other connections, if any, between the vehicle and the trailer.
