| No spray or weak spray | Clogged nozzle, clogged filter, insufficient paint, air in system, low pressure setting. | Clean nozzle (use reversible feature), clean filters, refill paint, prime the sprayer, increase pressure. |
| Uneven spray pattern | Worn nozzle, incorrect pressure, improper spraying technique. | Replace nozzle, adjust pressure, review spraying technique (consistent distance and speed). |
| Sprayer not turning on | No power, tripped circuit breaker, blown fuse. | Check power connection, reset circuit breaker, check and replace fuse (refer to component diagram for fuse location). |
