Fault finding
Check the machine's fault codes and wiring first; when the part itself has failed, replace it with one made to the same fit.
Damaged or worn part
Parts on the platform and chassis take knocks, weather and heavy use. Replacing a worn part before it fails keeps the machine on hire.
Same fit as the original
Made to the same mounting and connector as the part it replaces, so it fits without changes to the machine.
