PRODUCT DESCRIPTION
Hein-Werner hydraulic wheel dolly is designed to facilitate the removal and installation of pneumatic tires and wheel
assemblies found on many trucks, buses and trailers. This is NOT suitable for use as a wheel and tire puller. It is de-
signed ONLY for use in removing up to rated capacity tire and wheel assemblies which are not bound and/or seized up
at the brake drum or hub assemblies. This device is designed to be used in conjunction with jacks and jack stands.
Inspect before each use. Do not use if broken, bent, cracked, or damaged parts (including labels) are noted. Any
wheel dolly that appears damaged in any way, operates abnormally or is missing parts, shall be removed from service
immediately and the manufacturer notied. If you suspect that the product was subjected to a shock load (a load dropped
suddenly, unexpectedly upon it), immediately discontinue use until it has been checked by a factory authorized service
center (contact distributor or manufacturer for list of Authorized Service Centers). It is recommended that an annual
inspection be done by qualied personnel. Replace worn or damaged parts with Hein-Werner Authorized Replacement
Parts only. Labels and owner’s manuals are available from manufacturer.
SAFETY and GENERAL INFORMATION
Save these instructions. For your safety, read, understand, and follow the information provided with and on this wheel
dolly before using. The owner and/or operator of this equipment shall have an understanding of this equipment and
safe operating procedures before attempting to use. The owner and/or operator shall be aware that use and repair
of this product may require special skills and knowledge. Instructions and safety information shall be conveyed in the
operator's native language before use of this product is authorized. If any doubt exists as to the safe and proper use of
this wheel dolly, remove from service immediately.
To avoid crushing and related injuries and or property damage:

BEFORE USE (refer to Figures 1,2, and 3)
1. Verify that the product and the application are compatible, if in doubt call Hein-Werner Technical Service (816) 891-
6390.
2. Before using this product, read the owner's manual completely and familiarize yourself thoroughly with the product,
its components, and recognize the hazards associated with its use.
3. Assemble the handle for hydraulic unit.
4. To familiarize yourself with basic operation; position the hydraulic unit upright as shown in Fig. 2., assemble the handle,
locate and engage the release valve with the slotted portion of the provided handle, then turn the release valve:
a. Clockwise until rm resistance is felt to further turning of the handle. This is the ‘CLOSED’ release valve position used
to raise the load.
b. Counter-clockwise, but no more than 1 turn from the closed position. This is the ‘OPEN’ release valve position used
to lower the load.
5. With ram plunger fully lowered, locate and remove the oil ller plug. Insert the handle into the handle sleeve; then
pump 6 to 8 full strokes. Check oil level. Proper oil level is level with the bottom of the oil ller plug hole. Adjust as
needed, reinstall the oil ller plug.
6. Place the hydraulic unit (Fig. 2) into the hydraulic unit holder located beneath the tool tray. Position the unit such
that the saddle mates with the provided indentation. Adjustment of the saddle extension screw may be necessary.
7. Check to ensure the wheel dolly rolls freely and the hydraulic unit operates smoothly before putting into service.
Replace worn or damaged parts with factory Authorized Replacement Parts only. Contact the manufacturer or dis-
tributor of this product for a list of factory authorized service centers. Lubricate as instructed in Maintenance Sec-
tion.

With the release valve in the OPEN position (4b. above) and with saddle fully lowered, locate and remove the oil ller
plug. Insert the handle into the handle sleeve; then pump 6 to 8 full strokes. This will help release any pressurized air
which may be trapped within the reservoir. Reinstall the oil ller plug.
If necessary, use the hydraulic unit handle to engage the
Lift Arm Level Control lever to allow easier operation.

OPERATION (refer to Fig. 1,2, & 3)
VEHICLE PREPARATION
1. Locate vehicle on a hard, level surface, such as reinforced concrete, large enough to accommodate vehicle, jacks,
jack stands, and wheel dolly.
2. Set the emergency brake unless the rear drum, tire and wheel are all to be removed as an assembly.
3. Chock all unlifted tires in both directions AND take every precaution necessary to ensure the set up is stable and
will prevent all inadvertent vehicle movement.
RAISING THE LIFTING ARMS
1. Locate and enagage the release valve using the provided handle assy, then turn handle clockwise until rm
resistance is felt to further thread engagement.
Follow the vehicle manufacturers recommended removal and installation procedures for tire, wheel, hub,
or axle assemblies as needed! DO NOT remove more than is recommended by the vehicle manufacturer!
2. After the tire, wheel assembly has been loosened from the hub or axle and is ready to be removed, position the
dolly under the assembly to be removed. Pump until load reaches desired height. Adjust lift arm tilt such that the tire,
wheel assembly will nest securely between the lift arms without falling forward (toward the front wheels).
LOADING THE WHEEL DOLLY
NEVER load this device with more than the weight of the wheel assembly to be removed!
ENSURE that the vehicle is securely positioned and supported by a pair of appropriately rated jack stands.
NEVER use a wheel dolly as a wheel pulling device. Before transporting wheel assembly, ensure that it is
free from the hub or drum assembly and secured to the wheel dolly with the provided restraint.
1. When the weight of the loosened tire and wheel assembly is supported by the wheel dolly, carefully roll the wheel
dolly away from the drum or axle.
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 restraint.
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.
Follow the vehicle manufacturers recommended removal and installation procedures for tire, wheel,
hub, or axle assemblies as needed!
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
Important: Use only a good grade hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause failure of the jack and the potential for sudden
and immediate loss of load. We recommend Hein-Werner 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 ller plug.
2. Fill with oil even with the bottom of oil ller plug hole. Reinstall the oil ller plug.
CHANGING OIL IN HYDRAULIC UNIT
For best performance and longest life, replace the complete uid 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 ller plug.
3. Lay the jack on its side and drain the uid into a suitable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
4. Fill with oil even with the bottom of oil ller plug hole. Reinstall the oil ller 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.
CLEANING
Periodically check the 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.
STORAGE
Store the jack 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.
