Wheel Dolly
Before using your wheel dolly, you should check it for fluid leaking as this can be an indication that the seal may have been damaged. Throughout most of its life, you should not need to add any fluid or oil to the jack but there may be occasions when this is necessary. If you do need to add oil or fluid, refer to your owners handbook for advice on how to do this. As a general rule though, you will need to find the wheel dolly of which are for checking valves and the third is for adding the hydraulic oil or fluid.
A typical workshop press would be part theory and part practical. Staff needs to understand the principles of workshop press but also need real practical operation in a relatively safe environment. Basic skills are covered first and cover the theory required to operate a truck safely whilst specific job training incorporates any specific rules within the location.
