Operating Instructions
(Before Use)
1.
Check oil level.
With the jack in an upright position and the ram completely retracted, open release valve by turning
release assembly counterclockwise. Remove filler plug; the oil level should be just up to the hole. Fill if necessary
with clean hydraulic jack oil. NEVER USE BRAKE OR SHOCK ABSORBER FLUID.
2.
Lubricate internal components.
With release valve open, pump handle six full strokes to assure proper internal
lubrication.
3.
Bleed the hydraulic system.
During transit hydraulic jacks may become "air-bound", causing spongy ram action. To
bleed the hydraulic system:
a)
Close the release valve by turning clockwise.
b)
Insert handle in socket and pump jack
up to full height.
c)
Open the release valve, invert the jack and force the ram to retract.
Using the Jack
1.
To raise:
Turn release assembly clockwise to close release valve. Position jack where desired and adjust extension
screw if necessary, being sure that load is centered. Insert handle in socket and pump handle until load is at desired
height.
2.
To Lower:
Open release valve by slowly turning release assembly counterclockwise.
3.
For Horizontal Operation:
Place jack pump side down, then proceed as with vertical operation.
READ THIS OPERATION MANUAL THOROUGHLY and fully understand its contents before using the jack.
The manual explains important warning information.
This jack is designed for lifting purposes only, not for supporting loads.
Immediately after jacking, support vehicle (load) with appropriately rated stands or equivalent blocking.
DO NOT ALLOW JACK ALONE, TO SUPPORT VEHICLE (LOAD).
DO NOT OVERLOAD THIS JACK BEYOND ITS RATED CAPACITY.
This jack is designed for use only on hard level surfaces capable of sustaining the load. Use on other than
hard level surfaces may result in jack instability and possible loss of load.
Failure to read these warnings may result in loss of load, damage to jack and/or failure resulting in personal
injury or property damage.
NEVER
get your arm, leg, and/or body under a heavy load supported only by a jack.
When the handle is not in use, remove it from the body of the jack. Never use a handle other than the one
