Squeegee • Rough floor surfaces will cause the blades and wheels to wear out
more quickly. Replace as necessary.
Spray • Check spray pattern. If spray pattern will not pinpoint, clean orifice by
Gun removing it with an Allen wrench and flushing. Replace if needed.
• If nozzle becomes difficult to move from high to low pressure,
lubricate nozzle with lithium grease.

Hose
• Check for cuts or frays in the hose jacket, particularly at the end of the
fittings. Replace hose if cuts are found.
Water • Check condition of filter in water tank. Clean as needed.

tank by dipping the vacuum hose into the water tank and transferring
the water to the vacuum tank.
Vacuum • Empty and flush vacuum tank.

elsewhere.
• Discontinue use until leaks are repaired.
Electrical • The ground fault circuit interrupter (GFCI) must be tested before each
System
use.
