No Spray
I) with unit off, fill both tanks with water, remove and replace each tank, turn on
and pull trigger
check pump belt for damage or wear
check flow indicator filter, tighten cap securely
hold tank over sink, manually activate valve on the bottom of each tank and
check for flow, check for gaskets on the exit port of each tank
check for debris in the receivers for each tank
attempt to spray through upholstery tool, if sprays, the problem is either a
pinched hose, bad trigger valve, clogged heater or clogged spray tip (go to
#7): if no spray, the problem is either a bad pump, leaky Smart-Mix or leaky
tank receiver (go to #11)
actuate handle trigger slowly and feel for the actuation of the trigger valve (if
in doubt, remove upper handle assembly and actuate trigger valve manually)
unplug unit, remove main housing and check for pinched tubes
remove handle cover and check for pinched tubes
