LOWERING
1. Engage and slowly turn the release valve counterclockwise, but never more than 1 full turn.
TRANSPORTING LOADED WHEEL DOLLY
1. Ensure that wheel assembly is secured to the wheel dolly by means of the provided chain.
2. When wheel assembly has cleared the hub or the axle, lower the lift arms to the lowest position that will still allow
movement.
3. Push or pull wheel dolly to desired location.
CAUTION:
Follow the vehicle manufacturers recommended removal and installation procedures for tire, wheel,
hub, or axle assemblies as needed.
CAUTION:
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.
MAINTENANCE
NOTICE
:
Use only good quality hydraulic jack oil. Avoid mixing different types of fluid and N
EvEr
use brake fluid, turbine
oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of the jack and the potential for sudden and
immediate loss of load. Hein-Werner recommends hydraulic jack oil HW93291 or equivalent.
ADDING OIL TO 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.
NOTICE:
Dispose of hydraulic fluid in accordance with local environmental
regulations.
4. Fill with oil even with the bottom of oil filler plug hole. Reinstall the oil filler plug.
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. Apply grease to zerc fittings
on lift frame and rear wheel as required.
CLEANING
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as
needed and wipe with an oily cloth.
NOTICE:
Never use sandpaper or abrasive material on pump piston or ram surfaces.
STORAGE
Store the jack with the pump piston, ram plunger, and saddle fully lowered and the release valve open, but never more
than one turn. This will help prevent rust and corrosion to those critical surfaces.
