BEFORE USE
!
1. Inspect before each use. Do not use if bent, broken,
leaking or cracked components are noted. Ensure that
casters, rollers and lifting arms move freely. Check
and tighten any loose assemblies.
2. Verify that the product and the application are
compatible, if in doubt call Atd Tools Technical
Service (636)272-9050.
3. Read, understand and follow vehicle manufacturer’s
recommended tire change procedures.
4. With ram lowered, locate and remove oil filler plug.
This purges the hydraulic system of pressurized air
trapped in reservoir. Check fluid level. Proper level is
level with filler plug hole.
5. Reinstall oil filler plug.
WARNING
• Read and understand all warnings and instructional
material provided on and with this product before use.
• Do not exceed rated capacity.
• Use only on smooth, hard, level surfaces capable

• Before moving, lower the load to the lowest
possible point and assure that the load is centered
and secured with a load restraint device.
• Apply load as close to the vertical position of the
lifting arms as possible.
• No alterations shall be made to this product.
• Failure to heed this warning may result in personal
injury as well as property damage.

HOW TO USE
MAINTENANCE
1. Set emergency brake, chock tires of diagonally
opposed wheel(s) in both directions AND take every
precaution necessary to ensure set up is stable and
prevent inadvertent vehicle movement.
2. When tire & wheel assembly are ready to remove,
position wheel dolly to accept tire & wheel assembly
and secure load with restraint.
3. Use jack handle to turn release valve clockwise until
tight. DO NOT OVERTIGHTEN. Insert jack handle into
handle sleeve of hydraulic unit and pump until lifting
arms reach desired height.
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 and pump piston fully
depressed, adjust wheel dolly to level position.
Remove oil filler plug.
2. Fill until oil is level with the filler plug hole, reinstall oil
filler plug.
Note: Do not use wheel dolly to free a seized up wheel
assembly. For typical practice of taking out a seized
up wheel assembly, a long metal bar can be used to
pry the wheel assembly from the stuck wheel axle. If in
doubt, always follow vehicle’s manufacturer manual on
how to remove tire & wheel assembly.
Changing oil
For best performance, replace the fluid at least once per
year.
1. With saddle fully lowered and pump piston fully
depressed, remove jack from leveler assembly, then
remove the oil filler plug.
2. Lay the jack on its side and drain the fluid into a
suitable container.
4. Use load leveler to adjust the angle.
5. Carefully move loaded wheel dolly away from hub.
6. To install, reverse order.
Note: Before moving loaded wheel dolly, always secure
the load with provided chain.
Note: Dispose of hydraulic fluid in accordance with local
regulations.
3. Fill with good quality hydraulic jack oil. Reinstall oil
filler plug.
Lubrication
A coating of light lubricating oil to pivot points, axles and
hinges will help to prevent rust and assure that casters
and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs if
rust or corrosion. Clean as needed and wipe with a clean,
oil soaked rag.
Note: Never use sandpaper or abrasive material on these
surfaces !
Storage
When not in use, store the unit with pump piston and
ram fully retracted.
