Operating instructions:
WARNING
Improper use of this wheel dolly may result in injury/pinning of the user and others in close proximity to
the product.
1. When the load is in motion, it is important to stand with both feet behind the machine, with
hands gripping the handles (Figure 1 A) or the lowering handle (Figure 1 E).
2. Use the unit only on a solid, level surface.
3. When transporting a wheel, it must be in the lowest position.
4. The wheel dolly may not be used to lift loads heavier than the stated max. capacity (see
machine plate). Failure to do so can result in injury or property damage.
5. The manufacturer disclaims any responsibility for improper use, alterations in construction, use
of non-original parts and repairs and adjustments made by unauthorized personnel.
6. Do not use the unit if it is leaking oil or if the unit is otherwise functioning differently from when it
was new. If this is the case, have the unit inspected by authorised personnel.

Roller adjustment
You can adjust the rollers in width, so they fit
the current wheel size.
Lift the fork and move to the desired position.
When the fork is lowered, it locks.
It is important that both forks are moved the
same distance, so the load is symmetrical.

Using the wheel dolly
Figure 3
Picking up wheels from the ground
1. By setting the fork distance, you can pick up a standing wheel from the floor. The distance
between the rollers must be approx. 0.6 times the wheel diameter.
2. With the forks in the lowest position, move them in under the wheel as far into the lifting bed as
possible.
3. Note that the wheel is now resting against the crossbeam (Figure 3 A).
4. Secure the wheel using the safety bar (Figure 3 B). There are two safety bar sizes: the long bar
for dual wheels and the short bar for ordinary wheels. The safety bar should rest against the
wheel when the height barrier is lowered (Figure 3 C) and is locked using the locking screw
(Figure 3 D).

Wheel dismounting
1. With the vehicle lifted to working height, move the forks of the wheel dolly in under the wheel
you wish to dismount. The distance between the rollers should be approx. 0.6 times the wheel
diameter.
2. Pump the foot pedal (Figure 4) until the rollers on the dolly support the wheel; make sure the
wheel edge is pushed fully against the chassis frame (Figure 3 A).
3. Place the foot pedal in its top position so it is not in the way.
4. You can now move the wheel dolly with the wheel away from the vehicle. (After the wheel nuts
and bolts have been removed)
5. Secure the wheel using the safety bar (Figure 3 B). There are two safety bar sizes: the long bar
for dual wheels and the short bar for ordinary wheels.
6. Lower the wheel to the bottom position using the handle (Figure 5). (Turning the handle
clockwise lowers the dolly and turning it counterclockwise stops the lowering.)
7. Remove the safety bar.
8. You can now pull the wheel dolly away, and the wheel remains standing on the floor. Note that
the wheel can tip over or roll.
Wheel mounting
1. Grip the wheel between the rollers, so the wheel is standing in a stable position with the wheel's
edge against the chassis frame (Figure 3 A).
2. Pump the foot pedal (Figure 4) until the wheel is at the desired height.
3. Remove the safety bar (Figure 3 B) as late as possible in the work procedure.
4. Move the wheel into place and mount the wheel.
5. Lower the forks using the handle (Figure 5) and pull the wheel dolly away from the vehicle.
(After the wheel nuts and bolts have been removed.)
Wheel transport
1. Make sure the forks with the wheel are lowered to the lowest position.
2. Secure the wheel using the safety bar (Figure 3 B). There are two safety bar sizes: the long bar
for dual wheels and the short bar for ordinary wheels.
3. Check that the foot pedal is locked in its top position.

Maintenance
Annual inspection should be performed according to national regulations —and at least once a year.
The inspection should be performed by a trained professional.
Chassis, tower, forks and other chassis parts must be checked for damage and abnormal wear.
All moving parts must be inspected, cleaned and lubricated once a month.
In case of rust, remove the rust and protect with a rustproofing agent.
Check that the dowels on the forks and rollers are fully intact and working properly.
Check that retaining rings, nuts, bolts, and mandrels are fully intact and working properly.
If the unit requires repair, repair work must be done by a person with hydraulics experience/training.
If parts on the unit are replaced, they must be replaced with original parts.
If the unit has been defective or has malfunctioned, the unit must not be used until it has been
inspected by a person with hydraulics experience/training.
On the annual inspection, the machine must be serviced by a trained professional, so the above is
checked and any problems repaired.
Oil
Oil reservoir: Contains 0.95 litres.
Use only Hydraulic Oil AWS22
Do not use brake fluid, motor oil or the like!
Troubleshooting
1. The wheel lifter does not lift to the top position: The oil level is low. Lower the tower and fill to
the edge of the hole.
2. Poor pump function (“half” pump stroke): The oil level is too high. Lower the tower fully and let
the excess oil run out of the oil plug.
3. The tower sinks: Check that the release closes correctly.
If the error persists, repair the hydraulic unit.
Disposal
Drain the oil from the unit in a responsible manner and deliver the unit and other parts to an approved
waste recipient.
