Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this 
manual including all text under subheadings therein before set up or use of this product.
Bleeding
BEFORE EACH USE OR IF JACK PERFORMANCE DECREASES,  
check for excessive air and proper hydraulic fluid level in Jack. If Jack appears not to be working 
properly, it may be necessary to purge its hydraulic system of excessive air as follows: 
1.  Loosen the Fill Screw.
2. Twist the Handle counterclockwise to open the Valve.
3.  Check fluid level and, if necessary, top off 
according to Adding Hydraulic Fluid below.
4. Twist the Handle clockwise to close the Valve, 
then pump the Handle quickly several times.
5. Replace Fill Screw.
IMPORTANT:  After bleeding the Jack, test the 
Jack for proper operation prior to its actual use. 
6.  If, after bleeding, the Jack does not appear 
to be working properly, do not use it until 
repaired by a qualified service technician.
Adding Hydraulic Fluid
1.  Remove the Fill Screw.  Do not remove or 
loosen Safety Valve Cover Screws.
2.  Add high grade hydraulic fluid (sold separately) 
slowly until the fluid reaches 1/4″ 
below the top of the Fill Port.
Note: Do not touch the Handle 
when adding hydraulic fluid. 
3.  Replace Fill Screw.
Lifting
Park vehicle on a flat, level, solid, surface safely away from oncoming traffic.  Turn off the 
vehicle’s engine.  Place the vehicle’s transmission in “PARK” (if automatic) or in its lowest gear 
(if manual).  Set the vehicle’s emergency brake.  Then chock the wheels that are not being lifted.
1.  Slowly twist the Handle counterclockwise 
to lower the Jack.  Once the Jack is fully 
lowered, twist the Handle firmly clockwise.
2.  Carefully position the Jack’s Saddle under the 
vehicle manufacturer’s recommended lifting 
point. (See vehicle manufacturer’s owner’s 
manual for location of frame lifting point.)
3.  Pump the Handle until the top of the Saddle has 
nearly reached the vehicle’s lifting point.  Position 
the Saddle directly under the vehicle’s lifting point.
4.  To lift the vehicle, pump the Handle. 
Use smooth, full strokes.
5.  Select matching jack stands (sold separately) 
of appropriate capacity.  Set the jack 
stands to the same height according to 
the manufacturer’s instructions, making 
sure they lock securely into position.  
6.  Position the jack stands’ saddles under the vehicle 
manufacturer’s recommended support points.
WARNING!  Ensure that the vehicle support 
points are fully seated in the saddles of both 
jack stands.  Use a matched pair of jack stands 
per vehicle to support one end only. 
7.  Slowly twist the Handle counterclockwise to 
lower the vehicle onto the jack stands’ saddles. 
8.  Once the vehicle is fully seated on the 
jack stands, continue slowly lowering the 
Jack until it is completely lowered.
9.  Remove the Jack and store safely out of the way.
Lowering
1.  Carefully remove all tools, parts, etc., 
from under the vehicle.
2.  Position the Jack’s Saddle under the lifting 
point. Turn the Handle firmly clockwise and raise 
vehicle high enough to clear the jack stands. 
3.  Carefully remove the jack stands.
4.  Slowly turn the Handle counterclockwise 
to lower the vehicle onto the ground.
5.  Lower the Jack completely.  Store the 
Jack indoors out of children’s reach.

SAFETYOPERATIONMAINTENANCE SETUP
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.
Cleaning, Maintenance, and Lubrication
1.  BEFORE EACH USE, inspect the general 
condition of the Jack.  Check for:
•   loose hardware, 
•   misalignment or binding of moving parts, 
•   cracked or broken parts, 
•   any condition that may affect its safe operation.  
2.  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 4.
3.  AT LEAST ONCE EVERY THREE YEARS, 
change the hydraulic fluid:
a.  With the Jack fully lowered, 
remove the Fill Screw.  
b.  Tip the Jack over to allow the old hydraulic fluid to 
drain out completely.  Dispose of the old hydraulic 
fluid in accordance with local regulations.
c.  With the Jack upright, completely fill the 
Hydraulic Unit with high grade hydraulic fluid until 
the fluid is 1/4″ below the top of the Fill Port.
d.  Turn the Handle counterclockwise 
to open the Release Valve. 
e. Pump the Handle up and down quickly 
several times to purge air from the system.
f.  Recheck fluid level and re-fill as needed. 
g.  Replace the Fill Screw.
4.  AFTER EACH USE, wipe with a clean cloth. 
Store the Jack indoors out of children’s reach.

Troubleshooting
TO PREVENT SERIOUS INJURY: 
Use caution when troubleshooting a malfunctioning jack.  Stay well clear of the supported load. 
Completely resolve all problems before use.  If the solutions presented in the Troubleshooting guide 
do not solve the problem, have a qualified technician inspect and repair the jack before use.
After the jack is repaired:  Test it carefully without a load by raising and lowering it fully,  
checking for proper operation, BEFORE RETURNING THE JACK TO OPERATION.
DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
