Changes in the application rate indicate that your
ground speed has changed beyond the operating
range of the nozzles or there is a problem with the
sprayer system.

high pressure, even when engine is off.
High-pressure spray discharge could cause
serious injury or death.

the spray or stream from the wand at
people, pets, or non-work area property.
• Do not direct the spray at or near
electrical-power components or source.
• Do not repair the spray wand, hoses, seals,
nozzle, or other wand components; always
replace them.
• Do not attach the hoses or other
components to the nozzle at the end of the
spray wand.
• Do not attempt to disconnect the spray
wand from the machine while the sprayer
system is pressurized.
