What to do if the Stihl Paint Sprayer motor does not run when switched on?

If the motor hums but doesn't run, several factors could be at play. First, the mains voltage might be too low or improper, so check the electrical connection, plug, cable, and switch. An extension cord with the wrong cross-section or excessive length could also be the culprit; use a shorter, appropriately sized cord or connect directly. The mains circuit-breaker might have tripped; in this case, switch off the machine, actuate the spray gun until only water drips out, engage the safety catch, and reset the breaker. Finally, make sure to actuate the spray gun when switching on the machine.
