SERVICING THE RECOVERY TANK SWITCH(ES)
If the recovery tank fl oat switch(es) become dirty it can impair their 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. Dirty extended scrub system switches can prevent the optional extended scrub system from
functioning properly.
If daily rinsing of the recovery tank does not suf
fi ce to keep the switches clean you may need to disassemble them for cleaning. It is very important
that they be reassembled correctly in order to function. See Figure 6 for the correct orientation of the switch fl oat arms.
Refer to the service manual for detailed disassembly and cleaning instructions.
