If the recovery tank fl oat switch becomes dirty it can impair its proper operation. A dirty vacuum shut off switch can cause the vacuum motor to not
function at all or to not shut off when the tank is full.
If daily rinsing of the recovery tank does not suffi ce to keep the switch clean you may need to disassemble it for cleaning. It is very important that it
be reassembled correctly in order to function. See Figure 6 for the correct orientation of the switch fl oat arm.
Refer to the service manual for detailed disassembly and cleaning instructions.
