1.  Before each use, inspect the general condi-

tion of the jack. Check for broken, cracked, 

or bent parts, loose or missing parts, and 

any condition that may affect the proper 

operation of the product. Any jack that ap-

pears damaged in anyway must be removed 

from service. Have the problem corrected 

before further use. DO NOT use damaged 

equipment.

2.  Replace worn or damaged parts with Perfor-

mance Tool replacement parts. Be sure that 

only qualified personnel perform repairs. 

3.  Before each use, thoroughly test the jack 

for proper operation prior to its actual use. If 

the jack appears not to be working properly, 

follow bleeding instructions on page 3.

4.  When jack is not in use, ram and pump pis-

ton should be in fully down position to keep 

their machined surfaces free from corrosion. 

5.  Keep jack clean and well lubricated at points 

illustrated in figure 3. 

6.  For best results, use only hydraulic fluid with 

a rating of SAE 20 for refills. Check fluid level 

with jack in fully down position. Fluid level 

should be up to bottom of oil fill port. (See 

figure 5)

7.  Change the hydraulic oil at least once every 

three years:

  a. With the jack fully lowered, remove the oil 

filler plug on the side of the Housing.

  b. 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.

  c. With the jack upright, completely fill the 

housing with a high quality hydraulic oil (not 

included) until the oil just begins to run out 

of the oil fill hole. Be VERY CAREFUL not to 

allow dirt or foreign matter into the system.

  d. Then, reinstall the oil filler plug.
  e. Clean with a clean cloth using a detergent 

or mild solvent. Then, store the jack in a safe, 

dry location with the ram and pump piston 

in fully down position. Keep out of reach of 

children and other non-authorized people.

OPERATION

CARE & MAINTENANCE

stands of appropriate capacity (not included) 

beneath the vehicle at locations recommend-

ed by the vehicle manufacturer. DO NOT Get 

under the vehicle without jack stands. jacks 

are not designed to maintain heavy loads for 

long periods of time. DO NOT attempt to put 

jack stands simultaneously under both ends 

of vehicle or under one side of vehicle. NOTE: 

When using two jack stands, they must be at 

the same height.

10. SLOWLY turn the release valve counterclock-

wise to lower vehicle onto jack stands and 

remove jack.

IMPORTANT: 

NEVER MOVE JACK WHEN THE 

HANDLE IS IN OPERATING LEVER OR THE 

VALVE SLEEVE. DAMAGE TO THE PUMPING 

UNIT MAY OCCUR.

To lower:

1. Remove all tools, parts, etc. from under the vehicle.

2. Position the saddle under the lifting point. Turn 

the Handle firmly clockwise to close the valve 

release screw, and pump the upper/lower 

handle to raise the vehicle slightly above the 

saddle(s) of the jack stands. Then, collapse 

and remove jack stand(s).

3. SLOWLY turn the release valve counterclock-

wise with the handle just enough to allow 

controlled descent of the vehicle onto the 

ground. (Never more than two full turns).

4. Lower the jack completely. Then, store in a 

safe, dry location out of reach of children.

Monthly maintenance is recommended. Lubrication is critical to jacks as they support 

heavy loads. Any restriction due to dirt, rust, etc. can cause either slow movement or 

cause extremely rapid jerks, damaging the internal components. The following steps are 

designed to keep the jack maintained and operational.
