Transporting Loaded Wheel Dolly
1. Ensure that wheel assembly is secured to the wheel dolly by means of the provided chains.
2. When wheel assembly has cleared the hub or the axle, lower the lift arms to the lowest position that will still allow
wheel dolly wheel and caster movement.
3. Push or pull to desired location.
WARNING: Follow the vehicle manufacturers recommended removal and installation procedures for tire,
!
wheel, hub, or axle assemblies as needed!
!
WARNING: If the operating handle is worn, operates abnormally, or will not positively engage the release
valve, immediately discontinue use of the jack until a replacement handle assembly can be acquired.
WARNING: Use only premium hydraulic jack oil or equivalent hydraulic jack oil. Improper fluid can
!
cause premature failure of the jack and the potential for sudden and immediate loss of load.
MAINTENANCE
Adding Oil in Hydraulic Unit
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.
2. Fill with oil even with the bottom of oil filler plug hole. Reinstall the oil filler plug.
Changing Oil in Hydraulic Unit
For best performance and longest life, replace the complete fluid supply at least once per year.
1. Remove hydraulic unit from wheel dolly. Set hydraulic unit upright on a hard, level surface.
2. With saddle fully lowered, remove the oil filler plug.
3. Lay the jack on its side and drain the fluid into a suitable container.
Note: Dispose of hydraulic fluid in accordance with local regulations.
4. Fill with oil even with the bottom of oil filler plug hole. Reinstall the oil filler plug.
5. Install hydraulic unit back to the wheel dolly.
6. Perform Bleeding/Venting Trapped Air procedure.
Lubrication
A periodic coating of light lubricating oil to wheel dolly and hydraulic unit pivot points will help to ensure that all
moving parts function smoothly.
Note: Never apply oil to the saddle.
Storage
Store the hydraulic unit with the pump piston, ram plunger, and saddle fully lowered and the release valve open, but
never more than 1 turn. This will help prevent rust and corrosion to those critical surfaces.
Cleaning
Periodically check the hydraulic unit pump piston and 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.
