I agree to a point with luc h, but the responibility is just down with the rebuild company but also the end user, ie the operator.

In many surveys on internal machines. I have seen operators drive zoned machines outside there operating areas resulting in faulty sensor heads costing the company expensive repairs & leaving the machine open to accidents.

Customers should also be aware of how they clean there floors, various detergents can throw a sensor head out of calibration resulting in the machine not detecting the (LEL) the machine was set for.

The customer should also make sure the machine is serviced every three months, not by the hours the equipment is operated.

This way the customer is covered & the responsibilty is upon the supplier.
