Maintenance and Servicing

  Procedures not specifically explained in this manual must 

be performed only by a qualified technician.

TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:  Do not use damaged equipment.  

If abnormal noise or vibration occurs, have the problem corrected before further use.

1. 

BEFORE EACH USE,

 inspect the general 

condition of the tool.  Check for:

•  leaking hydraulic fluid,

•  loose hardware or parts, 

•  misalignment or binding of moving parts, 

•  cracked, bent or broken parts, and 

•  any other condition that may 

affect its safe operation.

Thoroughly investigate and correct the causes for 

all issues that are found.  Do not use Jack until all 

issues are understood and properly corrected.

ALSO, BEFORE EACH USE,

 thoroughly test 

the Jack for proper operation prior to actual use.   

If the Jack’s motion seems spongy or the 

Saddle does not lift completely, follow 

Bleeding instructions on page 6.

2. 

AFTER USE,

 wipe dry with a clean cloth. Then, 

store the Jack in a safe, dry location out of reach 

of children and other non-authorized people.

NOTICE:

  Storing the Jack in a humid area or 

exposing it to corrosive vapor voids the warranty.

3. 

Weekly - Jack Lubrication:

a.  Lubricate according to the below steps using 

only general purpose lithium grease.

b.  Inject grease into each of the grease fittings.

c.  Lubricate the linkages and pivot points lightly.

Note:

  Improper or inadequate 

lubrication voids the warranty.

4.  Change the hydraulic oil at least 

once every three years:

a.  With the Jack fully lowered, remove both Screws 

on the end of the Cover Plate that is closer to 

the Saddle.  Swing the Cover Plate open.

b.  Remove the Fill Plug on the top of the Cylinder.

c.  Tip the Jack to allow the old hydraulic oil 

to drain out of the Housing completely, 

and dispose of the old hydraulic oil in 

accordance with local regulations.

d.  Turn the Jack upright.  Add non-detergent 

22 weight hydraulic jack oil into the Fill Plug 

hole slowly until the oil level just reaches 

the top of the Piston inside the Cylinder.

e.  Replace the Fill Plug, close the 

Cover Plate, and reinstall the Screws.

f.  Follow instructions for 

Bleeding Trapped Air on page 6.
