SAFETY INSTRUCTIONS
BEFORE USE
1. Inspect jack before each use. Do not use if bent,
broken or cracked components are noted. Ensure
that casters move freely. Check for and tighten any
loose assemblies.
2. Verify that the product and the application are
compatible.
3. Remove oil filler plug/screw prior to initial use to
confirm oil level is at or just above the inner cylinder
as seen from the reservoir, fill as needed and
reinstall oil filler plug/screw.
• Study, understand, and follow all printed materials
provided with/on this product before use.
• Do not exceed rated capacity.
• Use only on hard, level surfaces capable of supporting
rated capacity loads.
• Use of this jack is limited to the removal, installation
and transportation of transmissions, transfer cases
and transaxles. Do not use a transmission jack to tilt
or support a vehicle.
• Ensure the center gravity of load is centered on the saddle.
• For your safety, do not exceed 100 tilt angle of the
saddle assembly in all directions.
• Adequately support the vehicle before starting repairs.
• Use only chains and slings provided.
• If loaded jack must be moved, make sure that the load
is secured, stable and in lowest position.
• This is a lifting and lowering device only.
• Transfer load immediately to appropriate support
device for service or repair.
• Shock loads may cause the sudden loss of load and/ or
cause the jack to tip or flip over violently, bend or break.
• No alterations shall be made on this product
• Failure to heed these markings may result in personal

Lower saddle:
Caution! Be sure all tools and personnel are clear
before lowering load. Dynamic shock loads are created
by quickly opening and closing the release valve as the
load is being lowered. The resulting overload may
cause hydraulic system failure.
1. Slowly, gently turn the release valve knob
counterclockwise, never more than 1/2 full turn
until the load is completely lowered.
2. Immediately transfer the load to an appropriate
repair fixture.
! WARNING
To avoid crushing and related
injuries:
NEVER work on, under or
around a load supported only
by a jack. Immediately
transfer the load to an
appropriate work station.

MAINTENANCE
Important: Use only a good grade hydraulic jack oil. Avoid
mixing different types of fluid and NEVER use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin.
Improper fluid can cause premature failure of the jack
and the potential for sudden and immediate loss of load.
We recommend Mobil DTE 13M or equivalent.
Adding oil
1. With saddle fully lowered, set jack in its upright,
level position. Remove oil filler plug/ screw.
2. Fill until oil is level with the oil filler hole, reinstall oil
filler plug/ screw.
Lubrication
A periodic coating of light lubricating oil to pivot points,
axles and hinges will help to prevent rust and assure
that wheels, casters and pump assemblies move freely.
Cleaning
Periodically check the ram for signs of rust or
corrosion. Clean as needed and wipe with an oily
cloth.
Note: Never use sandpaper or abrasive material on
these surfaces!
Changing oil
For best performance and longest life, replace the
complete fluid supply at least once per year.
1. With saddle fully lowered, set jack in its upright,
level position. Remove the oil filler plug/ screw.
2. Lay the jack on its side and drain the fluid into a
suitable container.
Note: Dispose of hydraulic fluid in accordance with
local regulations.
3. Set jack in its level upright position.
4. Fill with oil until just below the rim of oil filler hole.
5. Reinstall oil filler plug/ screw.
TROUBLESHOOTING
Storage
When not in use, store the jack with pump piston and
saddle in lowest position.
