Ensure that the shock absorber is supported 

a. 

as the top cap nut is removed to prevent it 

falling down through the coils and causing 

injury.

Once compressed and the strut removed, it 

13. 

is recommended to release the tension on 

the spring. 

Do not leave the spring under compression 

a. 

unattended and do not leave in compres-

sion for prolonged periods. I.e. overnight.

Allow the spring to gradually decompress by 

14. 

carefully pressing the Valve Release Pedal 

(6) keeping your hands and fingers away 

from the spring assembly.
Replace the spring or shock absorber as 

15. 

necessary and reassemble the strut by first 

compressing the spring and then introduc-

ing the shock absorber up through the lower 

Shoe (28) and compressed spring coils. 

Re-position the upper strut mount and se-

a. 

cure with the top cap nut.

Before releasing the compression, ensure 

16. 

that the top cap nut is securely tightened ac-

cording to the manufacturer’s specs.
Release the compression slowly keeping 

17. 

your hands and fingers away from the spring 

assembly.

Be sure that the spring ends are firmly and 

18. 

securely seated in the upper and lower 

Shoes of the Compressor before removing 

the strut from the Spring Compressor.

MaIntenance

Before each use, check the compressor to 

1. 

ensure it is not damaged or worn. If in any 

doubt DO NOT use the tool.

Remove it from service immediately and 

a. 

have it replaced or repaired by a qualified 

technician.

Refilling the hydraulic system with oil is rarely 

2. 

necessary but the oil level should be checked 

in the event of a loss of performance. 

To check oil level, ensure the Under Strut 

a. 

Support (24) is fully lowered, remove filler 

plug and check that level is within .4" of filler 

hole. Add hydraulic jack oil if necessary.

WarnInG:

  DO NOT use brake fluid, or any fluid 

other than hydraulic jack oil as this will cause 

serious damage to the jack and invalidate the 

warranty!

bleeding the Hydraulic system

The Strut Spring Compressor must be se-

3. 

curely mounted on a flat and level surface. 

Wipe the Oil Filler Plug (38) and its surround-

4. 

ing area at the side of the Ram (7). 

With the tip of a flat tip screwdriver, pry and 

5. 

remove the rubber Oil Filler Plug. 
Pour fresh hydraulic jack oil into the Ram (7) 

6. 

until it starts to overflow. 

Step on the Valve Release Pedal (6) and 

7. 

allow the Under Strut Support (24) to be 

lowered completely. 
While holding the Valve Release Pedal (6) 

8. 

down, rapidly pump the Foot Pedal (5) at 

least five full strokes. This should purge the 

air out of the system. 
Repeat step 6 above to make sure that the 

9. 

Ram (7) is filled with oil. 

Wipe the plug and place its edge against 

10. 

the fill-hole and while applying thumb force 

behind the plug, work the rubber plug back 

into the fill-hole with the aid of the flat tipped 

screwdriver. 
 After the plug is inserted, wipe off spilled oil 

11. 

from jack exterior with a clean and dry rag. 

cautIon:

 DO NOT operate the jack when the Oil 

Filler Plug (38) is removed.
