and its proper use when servicing motor vehicles and their
components. Warning information should be emphasized
and understood. If the operator is not fluent in English,
the manufacturer’s instructions and warnings shall be

Visual inspection should be made be fore each use
of the bottle jack, checking for dam aged, loose or
miss ing parts. Each jack must be im me di ate ly in spect-
ed by a man u fac tur er’s re pair fa cil i ty if sub ject ed to an
ab nor mal load or shock. Any jack which ap pears to be
damaged in any way, found to be badly worn, or op er ates
ab nor mal ly MUST BE RE MOVED FROM SER VICE until
nec es sary re pairs are made by a man u fac tur er’s au tho-
rized repair fa cil i ty. It is rec om mend ed that an annual
in spec tion of the jack be made by a man u fac tur er’s au tho-
rized re pair facility and that any de fec tive parts, decals or
warning labels be replaced with man u fac tur er’s specified
parts.
A list of authorized repair facilities is avail able from the
man u fac tur er.
Before using the jack:
1. Using the handle, open the re lease valve by rotating it
coun ter clock wise one full turn.
2. Place the handle in the handle sock et and pump
about 6 full strokes to purge the air from the pump
and valving.
3. Close the release valve. Pump the han dle until the jack
has reached full ex ten sion. Continue to pump several
times to purge air from un der the ram.
4. Open the release valve and push ram into its lowest
position. Close the release valve and op er ate nor mal ly.
Note: If the jack responds im me di ate ly to pump
action, it is free of air and ready for operation. If not,

OPERATING INSTRUCTION S
MAINTENANCE
OWNER RESPONSIBILITY
To use the jack:
1.
To raise a load, close release valve by ro tat ing the
handle firmly in a clock wise direction (do not
over tight en). Care ful ly position the jack under the load
and pump the jack handle to raise the load to the
desired height.
2. If raising a vehicle, always support it with vehicle
stands before working on the ve hi cle or getting under
it for any reason.
3. To lower the load, slowly rotate the jack handle
coun ter clock wise just enough to open the release
valve. Open ing the release valve more per mits the load
to de scend faster.
IMPORTANT: As with any hydraulic unit, this unit
may occasionally become “air bound” due to be ing tipped
over during shipment. To purge the air from the oil lines,
open the release and pump rap id ly a few strokes. Close
release and pump to full height, then open the release to
allow the ram to descend rapidly. If the pump still seems
“spongy”, repeat the procedure.
1. To add oil, place jack in upright po si tion with pump
plunger down. Re move filler plug and add
hydraulic jack oil to level of filler hole. Be sure oil is
clean and be careful to keep dirt out of jack.
DO NOT USE BRAKE, SHOCK AB SORB ER, OR
TRANS MIS SION FLU ID.
2. Periodically lubricate the points in di cat ed with SAE 30
oil. Keep jack clean.
3. Occasionally check extension screw and pump
plung er for corrosion. Keep these parts lubricated to
pre vent cor ro sion.
4. When not in use, store jack in up right position in a dry
location with pump plung er and extension screw in
lowest position and release valve closed.
