GENERAL

Your Pick Up Truck Lift has four extension settings for the EXTENDIBLE BOOM (#7). Each of these extension settings has a weight limit that is clearly marked on the BOOM (#4). Do not exceed these weight limits as it may cause damage to the PICK UP TRUCK LIFT and\or cause bodily harm.

Prior to use, liberally grease the unit using the GREASE FITTING (#3) located on the BASE (#1). Swivel the BASE on the POST (#2) 360º while greasing to ensure optimum lubrication.

Warning: When installing the Pick Up Truck Lift, please note that the Base (#1) must be securely bolted to the frame of the truck; bolting the truck lift to the bed of the truck wil not provide the necessary support needed.

the POST so that the BOOM (#4) is pointing towards the object to be lifted.

locking the EXTENDIBLE BOOM (#7) in place using its SMALL LOCK PIN (#8). Do

not exceed the weight limits marked on the side of the boom.

Step 3: Hook around the article so that its weight is centered.

Step 4: Place the slotted end of the PUMP HANDLE (#21) over the PUMP RELEASE VALVE

(#13) and close it by turning it in a clockwise direction.

Step 5: Insert the PUMP HANDLE into its connector and lift the BOOM by pumping the handle

in an up and down motion.

Step 6: When the article has been lifted to the desired height, it may be moved over the truck

bed by slowly swiveling the BASE (#1) on its POST until the object is directly over the truck bed. Do not attempt to extend the BOOM further while the object is still Attached. If the object needs to be moved further; lower it, adjust the BOOM, and re-lift it.

PUMP RELEASE VALVE in a counterclockwise direction.
