REGULAR MAINTENANCE

Before each use, the BACK PACK POWER SPRAYER should be inspected for proper assembly
and fitness of all components. All fasteners should be checked for correct tightness. Always
inspect for fuel leaks.

more often with extreme conditions).
To inspect, remove the air filter cover and remove the filter from the case.
