Knowhow is the difference

Are there any visible cracks in the paint covering the welds?

Action 3F: In case of visible cracks in the paint, place the wheel dolly under controlled pressure – at nominal

capacity.

At this pressure, check whether the cracks expand.

If so, it shows the same defects as described in 3D.

The solution is the same as 3D. If the paint's cracks do not expand, the problem is only superficial.

Do the transport wheels on the wheel dolly rotate freely; are the wheels still round and without cracks?

Action G: If one of the three problems arises, replace the wheels with new wheels. Make sure that the axle

for both the front and back wheels is well greased.

Is the wheel dolly so dirty that some of the parts are not working properly?

Action 3H: Carefully clean the wheel dolly and especially the moving parts. If cleaning with soap and water,

all moving parts must then be greased well before use.

Never wash the dolly using a high-pressure cleaner, as this may damage the dolly's surface and

components.

If the handle for pumping and the pedal for switching direction working?

Action 3J: The pumping rod and change-over valve system are manually operated. Make sure that

movements with the pumping rod are driving the hydraulics. To check the change-over valve, actuate the

valve's pedal and make sure that its switching and subsequent movements with the pumping rod drive the

hydraulics as desired.

Does the lifting roller look robust and intact?

Action 3K: The rollers should have a flat, uniform and rust-free surface with no dents, and they should roll

easily without a load. Replace any roller that does not comply with a new roller.

Does the safety lock look intact and work properly?

Action 3M: The safety lock must be clean, rust-free and work exactly as described in operation. If not,

replace it with a new lock.

Are all safety labels present as indicated in the label overview?

Action 3N: In case of any missing or damaged safety label, contact Compac to purchase a new label.

4. Testing and adjustment

Pump the wheel dolly together with NO LOAD. If the wheel dolly cannot be pumped together entirely -

check the oil level (See action 3A) or check for any foreign objects that may have become lodged in the

dolly and which are preventing the moving parts from moving normally.

Pump the wheel dolly out to its maximum width again. If you are unable to do this, the dolly may require oil.

Check the oil level and fill if necessary, or check for the presence of grime or foreign objects that are

preventing the dolly from reaching its maximum width.

Testing the hydraulic system under pressure

Place the wheel dolly in a testing device (See item 2 "Test equipment").

Build up pressure by pumping the lifting roller around the load until it is off the floor.

Let the dolly stay under this pressure for two minutes.

After two minutes, if there is still pressure of at least 500 kg, the return system is air-tight and functioning

properly.

(There are no leaks in the hydraulic system). Release the pressure by pumping back.
