USING THE SERVICING PLATFORM
Begin by placing the unit on the Servicing Platform. Servicing Platform should fit securely under
the unit and raise its wheels off the servicing surface.
PRELIMINARY DIAGNOSTIC CHECKS
1. Test the trigger mechanism. There should be 1/4" of free travel before 1/4" of resistance.
If not, ensure that valve is seated correctly. If valve is OK, replace the trigger rod.
2. Check resistance of the SmartMix knob by turning it from left to right several times. If
difficult to turn, check to see that the piston is installed correctly (with housing removed).
