ture, unthread the socket and remove

the locking sleeve.

The strut length may need to be adjusted

to fit from ball stud to ball stud. The

length is adjusted by adding a M6 washer

between the socket and strut body

The swing arm should make contact with

the rubber bumper just before the strut

locks out. You can adjust the stopper or

the strut length to achieve this

Ideally the swing arm will need a light

push to lock out.

Be sure to position the red “Lock” so that

it is easy to push (Photo 25B).

26 Mounting the Hi-Lift Jack

Place the Jack into the bracket ash show.

The curved part of the clamp goes around

the handle.

Make sure that the running gear of the

jack is near the bottom of the jack. This is

so the clamp doesn't clamp down on the

handle socket.

Stowe the jack with the reversing latch in

the upright position.

Adjusting for proper fit.

Test fitment of the swing arms by opening

and closing them gently a few times.

Items that are adjustable:

If the pin is not riding up the striker pad

properly you can add an M10 thick washer

just below the pin handle.

Swing arm bearing preload: adjust preload

by tightening or loosening the castle nut

on the bearings. The strut should open the

arm slowly when enough preload is

achieved

Striker height: adjust striker height by

shimming the striker up or down. When

the carriers are fully loaded there should

be a .0”- .060” (0-4 business cards thick)

gap between the striker and swing arm.

If more than 1 shim is needed under the

striker pad, an additional washer may

need to be placed under the pin handle

(M10).

Handle effort may be adjusted by length-

ening or shortening the U-Bolt on the han-

dle.

Adjust the U-bolt equally on both sides.

The tension may change slightly after

tightening the bottom jam nut.

Wedges should be adjusted so that there

is no movement in the swing arms after

latching. Also, both rubber bump stops on

the swing arms should be in contact with

the bumper face.

Hardware: 2- Gas Struts

2- M10 Thick Washers
