OPERATING INSTRUCTIONS________________________________________________

Step 1. Positioning the Strut Assembly

A) Adjust lower right hook to a position just below the lower center hook. Adjust lower left hook to a position

just above the lower center hook.

B) Place strut assembly on the lower center hook using the lowest possible coil of the spring.

C) Engage lower left and right hooks with spring. Center the spring within lower hooks. The three lower

hooks should be equally extended.

CORRECT INCORRECT

D) Align strut assembly by adjusting the lower left and right hooks. When properly aligned, the spring of the

strut assembly will be parallel to the posts of the tool when viewed from both the front and side.

C) Mark upper strut parts to aid in reassembly.

D) Remove the piston rod nut.

E) Remove the clamp while holding strut. Carefully remove strut and related parts.

F) Service or replace strut as required. It is not necessary to release spring from tool when servicing strut

NOTE: When replacing top spring seat or spring, make note of the position of the spring seat and spring before

releasing spring from tool. Replace new strut parts in tool in the same position as the old.

CAUTION

♦If the strut assembly is difficult to compress or the spring bows or

tilts, release tension and reposition the strut assembly.

♦Keep fingers and hands clear of the upper hook area at all times.

WARNING

♦Use extreme care when working with a compressed spring.

♦Never remove the piston rod nut when there is any spring pressure

on the lower spring seat.

Step 3. Reassembly

A) Position the new strut within spring. Secure strut to spring with the clamp.

B) Install piston rod nut. NUT MUST BE FULLY ENGAGED ON PISTON ROD THREADS!
