and follow all
instructions before operating this
device. 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 vehicle manufacturer.
Ensure that the lift point is properly
centered on the jack saddle.
Always wear safety googles 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 2 as reference.
1. Prior to use, remove oil filler plug to
let any trapped air escape. Ensure
the oil level is even with or just
below the oil filler plug hole.
Reinstall oil filler plug.
2. Thoroughly lubricate all moving
parts of the jack.
a. Raise the saddle to full height by
closing release valve and pumping
handle.
b. Oil surface of ram as well as all
moving parts in the handle and
lifting mechanism.
Operation
LIFTING
1. Prevent inadvertent vehicle
movement by fully engaging
emergency brake, putting
transmission in park. Use wheel
chocks in pairs on the wheel
diagonally opposed to the wheel or
axle lifted.
2. Close release valve by turning handle
clockwise until it is firmly closed.
3. Position jack under load and turn
extension screw or saddle until solid
contact can be made with load to be
lifted.

Operation (Continued)
4. Operate jack 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 jack
stands.
LOWERING
IMPORTANT: Avoid “shock loads”
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.
1. Insert handle onto release valve and
slowly turn handle counterclockwise
no more than one full turn.
2. Push handle sleeve down manually
if still extended to reduce piston
exposure to rusting.
Maintenance
IMPORTANT: Use only a good grade
hydraulic jack oil (Mobil DTE 13M or
equivalent), avoid mixing types of oil.
Do not use brake fluid, alcohol,
glycerin, 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 plug.
2. Fill until oil is level with or just
below filler plug hole.
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
oil filler plug.
3. Lay the jack on its side and allow the
oil to run out into suitable drain pan.
Dispose oil 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.
STORAGE
When not in use, always leave the
saddle and pump piston all the way
down.
