1. Is the engine switch in the ON position?
2. Is there fuel in the fuel tank?
3. Is gasoline reaching the carburetor?
To check, press the priming pump several times.
4. Is the spark plug in good condition?
Remove and inspect the spark plug. Clean, readjust gap and dry the
spark plug. Replace it if necessary.

servicing dealer.
When the backpack sprayer sprays irregularly:

ATOMIZING PRESSURE NOT RAISED
