routine actions which keep your sprayer in operation and
prevents trouble in the future.

same rate on both sides of motor.
Check both brushes.
Check sprayer stall.
With sprayer gun NOT triggered,
sprayer motor should stall and not
restart until gun is triggered again.
If sprayer starts again with gun NOT
