Troubleshooting
NOTE: When the PRIME/SPRAY valve is on SPRAY and there is flow through the return tube, remove the
PRIME/SPRAY valve and clean or replace it.
NOTE: The electric motor should always be kept clean and dry. Paint acts as an insulator. Too much paint on the
motor will cause the motor to overheat.
