2. Place a pan under the work area
to catch used oil. Dispose of
used oil in accordance with ap-
plicable laws and regulations.
3. Remove oil fill plug and check
ball (not shown - behind plug).
It may be necessary to position
the oil fill hole downward, so that
check ball drops out.
4. Place jack so that oil fill hole is
facing up. Add new oil until oil is
level with fill hole.
Use only high quality oil of the
proper specifications (see Oil
Specifications chart, below).
5. Reinstall check ball and oil fill
plug.
CHANGING OIL
Periodic oil changes are not re-
quired unless it is suspected that
the oil is contaminated, or that mois-
ture has entered the system.
LUBRICATION
Periodically lubricate all pivot pins
and other moving parts.
RUST PREVENTION
Check ram every 3 months for any
sign of rust or corrosion. Clean as
needed and wipe with an oil satu-
rated cloth.
NOTE:
When not in use, always en-
sure that the pump plunger is as far
inside the jack housing as possible.
This will reduce exposure to rusting.
Refer to figures 2, 3, 4 and 5
for reference.
Pre Operation
1. Occasionally, hydraulic jacks be-
come air-bound during shipment
and will not function properly. To
correct this condition:
a. Open release valve by turning
it counterclockwise about ½ turn.
(Do not open release valve more
than 1 turn from fully closed.)
b. Place handle in handle socket
and pump the handle 6-8 full
strokes to purge air from hydrau-
lic system.
c. Close release valve by turning
it fully clockwise. Verify that ram
extends smoothly when handle is
operated.
2. Thoroughly lubricate all moving
parts of the jack. Oil surface of
ram as well as all moving parts in
the handle and lifting mechanism.
3. Inspect jack before use. Do not
use if cracked, broken, or dam-
aged parts are noted.
Operation
LIFTING
1. When lifting vehicles, help pre-
vent inadvertent vehicle move-
ment by fully engaging emergen-
cy brake and putting transmission
in park. Use wheel chocks in
pairs on the wheel diagonally op-
posed to the wheel or axle lifted.
2. Open release valve by turning
it counterclockwise about ½
turn. (Do not open more than 1
turn counterclockwise from fully
closed.)
3. Position jack under proper lift
point.
IMPORTANT: Position jack
linkage and clevis as required,
so that these parts do not rub
against the ground or other work
surface during jack operation. Do
not allow jack handle socket to tip
jack upward during pumping.
4. Close release valve by turning it
fully clockwise.
5. Pump handle until the ram end
makes solid contact with the load.
6. Continue pumping until load is
raised to desired height. Immedi-
ately transfer load to appropriate
jack stands or other properly rated
device.
WARNING
Off center loads
and lifting on unlevel surfaces
may damage the jack or cause
personal injury. Stop pumping
IMMEDIATELY if the maximum
stroke indicator line appears.
LOWERING
1. Open release valve by turn-
ing it counterclockwise about ½
turn. (Do not open more than 1
turn counterclockwise from fully
closed.)
CAUTION
Avoid “shock
loads” created by quickly opening
and closing the release valve as
load is being lowered. Shock
loads may overload the hydraulic
circuit and cause damage to the
jack.
2. After lowering, close release valve
by turning it fully clockwise.
Maintenance
ADDING OIL
1. Be sure ram is fully lowered and
that pump plunger is as far inside
the jack as possible.

IMPORTANT:
Use only
a good grade hydraulic
jack oil and avoid mixing
different types of oil. Do
not use brake fluid, alco-
hol, glycerin, motor oil,
or dirty oil. Improper fluid
can cause serious inter-
nal damage to the jack,
rendering it inoperative.
