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.

Step 8: Attach the unit to the desired position by bolting the BASE down using the two STEEL

ANGLES (#26) as backing plates (see Figure 7). On most trucks a desirable position

is just behind the wheel well so that the BOOM may be stored over the wheel well.

OPERATION

Step 1: Release the LARGE LOCK PIN (#20) located on the body of the POST (#2) and swivel

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

Step 2: Position the HOOK AND CHAIN (#27) over the article to be moved by adjusting and

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.

Figure 8 — Operating the Pickup Truck Lift

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 At-

tached. If the object needs to be moved further; lower it, adjust the BOOM, and

re-lift it.

Step 7: Lower the object onto the truck bed by using the PUMP HANDLE to slowly turn the

PUMP RELEASE VALVE in a counterclockwise direction.
