General Safety Information
Study, understand,
and follow all
instructions before operating this device.
This is a lifting device only. Intended use
is for lifting part of a total vehicle, only one
wheel or axle at a time. Immediately after
lifting, support vehicle with appropriate
means. Do not exceed rated capacity. Use
only on a hard level surface capable of
sustaining rated capacity loads. Lift only
on those areas of the vehicle as specified
by the vehicle manufacturer. Ensure that
the lift point is properly centered on the
jack saddle. Always wear safety goggles
when using this equipment. Inspect jack
before each use. Do not use if bent,
broken, leaking, or damaged components
are noted. No alteration of this product is
allowed. Do not use this device for any
purpose other than that for which it was
intended. Failure to heed any one or
combination of these warnings may result
in severe personal injury and/or property
damage.
Before Use
Use figure 1 as reference.
1. Occasionally hydraulic jacks become
air bound and will not function properly.
To correct this condition, remove oil
filler screw. This will allow any
pressurized air to escape.
a. Ensure the oil level is even with or
just below the oil filler hole.
b. Reinstall the oil filler screw.
2. Thoroughly lubricate all moving parts
of the jack.
3 With notched end of the handle, close
release valave by turning it clockwise
firmly and pump saddle to fully
extended, then open release valve to
lower the saddle.
Operation
LIFTING
1. Assemble 3-piece handle by lining up
spring pins with corresponding slots.
2. Secure load to prevent inadvertent
shifting and movement.
3. Close release valve by turning handle
clockwise until it is firmly closed.
4. Position jack under load and pump
handle until saddle contacts load.
Off center loads
and loads lifted while
jack is not level may damage the jack or
cause personal injury.
5. Raise load to desired height and
immediately transfer load to proper
mechanical means such as jack
stands.
LOWERING
Be sure all tools
and personnel are
clear before lowering load.
1. Insert handle onto release valve and
slowly turn handle counterclockwise no
more than half full turn at a time.
2. Push handle sleeve down manually if
still extended to reduce piston
exposure to rusting
IMPORTANT: Avoid “shock load” created
by quickly opening and closing the
release valve as load is being lowered.
This may result in an overloading of the
hydraulic circuit and possible damage to
the jack.

Maintenance
IMPORTANT: Use only a good grade
hydraulic jack oil such as Mobil DTE 13M
or equivalent. Avoid mixing types of oil.

detergent motor oil, or dirty oil. Improper
fluid can cause serious internal damage to
the jack rendering it inoperative.
ADDING OIL
1. With saddle fully lowered and piston
depressed, set jack in its upright level
position and remove oil filler screw.
2. Fill until oil is level with or just below
filler hole, then reinstall filler screw.
CHANGING OIL
1. For best performance and longest life,
replace the complete oil supply at least
once a year.
2. To drain oil completely, remove the filler
screw.
3. Lay the jack on its side and allow the oil
to run out into suitable drain pan.
Dispose of in accordance with local
regulations.
4. Replace with proper oil as described
above.
LUBRICATION
Add lubricating oil to all pivoting sections
every 3 months.
RUST PREVENTION
Check ram and piston for signs of rust on
a regular basis. Clean as needed with a
lint free, oil saturated cloth.
NOTE: When not in use, always leave the
saddle and ram all the way down.
