WARNING
&
FAILURE TO READ THESE WARNINGS MAY RESULT IN PROPERT Y DAMAGE AND OR PERSONAL INJURY.
-
Use as lifting device only.
- Use only o
n hard, level surface.
- Do not modify jack.
- Support l
oad by appropriate means after liing
- Do not exceed rated capacity.
- Center load on the jack.
- Only use attachments and/or adapters supplied with or sold specifically for the jack.
- Only lift areas of the vehicle designated by the vehicle manufacturer.
INSPECTION
Prior to each use, visually inspect for leaking hydraulic oil, damaged, loose or missing parts. If jack is wo or damaged
remove from service and contact your nearest service center for repair.
OPERATION
1. Tightl
y close the release valve knob (located on top of the "T" handle) by turning it clockwise.
2. Center the load on the jack saddle. Connect the air supply, and squeeze the air valve lever to raise the load. Release the
air valve lever to stop movement.
3. Transfer the load to support stands.
4. To lower the jack, open the release valve knob gy SLOWLY turning it counterclockwise.
NOTE: To adjust the handle, pull up and then release the lever to lock it in one of the positions.
Bleeding The Jack
Air bubbles can become trapped inside the bydraulic system, reducing the efficiency of the jack. Purge air from the
system as needed by following these steps:
1. With the jack sitting on its base and the ram retracted, bleed air by opening the release valve.
2. Pump for 10 seconds.
Pump Prime Instructions
The air/hydraulic pump may lose its prime during shipment or after
long periods without use. To prime the pump, llow these steps:
1. Remove the upper cover.
2. Loosen the hex socket bolt one-half turn. See Figure 1.
3. Close the release valve.
4. Operate the air pump while repeatedly tightening and loosening
the bolt.
5. When the piston begins to rise, tighten the bolt. Veri that the
piston can rise to the maximum height position.

Check oil level. With the jack in an upright position and the ram completely retracted, open the release valve (turn coun
ter-clockwise) and remove the filler plug. The oil level should be just up to the hole. Fill if necessary with cleanhydraulic
jack oil.
Lubricate internal components. With the release valve open, manually pump the handle six times.
Keep the jack clean. Occasionally lubricate the handle socket pivot point, extension screw, release screw thread, and
air valve to prevent corrosion.
Problem
Erratic Action
Ram does not advance
Ram only extends partially
Ram advances slowly
Ram advances but doesn't
hold pressure
Jack leaks oil
Ram will not retract, or
retracts slowly
Cause
1. Air in system
2. Viscosity of oil too high
3. Ram sticking or binding
4. Internal leakage in ram
1 . Release valve is open
2. Low/no oil in reservoir
3. Air locked system
4. Load is above capacity of system
5.
Pump lost its prime
1. Low oil level in reservoir
2. Piston rod is binding
1. Low air pressure
2. Pump not working correctly
3. Leakinq seals
1 . Release valve is open
2. Ram seals are leaking
3. Pump check valve not working
4. Overload valve leaking or
not adjusted
1. Worn or damaged seals
1 . Release valve is closed
2. Reservoir too full
3. Ram damaged internally
Solution
1. With jack sitting on its base and m
retracted, bleed air by opening release
valve. Pump for 10 seconds.
2. Change to a lower viscosity oil.
3. Look r di, gummy deposits, leaks,
misalignment, wo pas, or defective
packing.
