3.1 MACHINE MAINTENANCE
Floor
Squeegee
Check condition of squeegee blades and wheels on the floor tool.
Rough floor surfaces will cause the blades and wheels to wear out more
quickly. Replace as necessary
Spray
Gun
Check spray pattern. If spray pattern will not pinpoint, clean orifice by re-
moving it with an Allen wrench and flushing. Replace if needed.
If nozzle becomes difficult to move from high to low pressure lubricate noz-
zle with lithium grease.
Pressure
Hose
Wipe clean after each use.
Check for cuts or frays in the hose jacket, particularly at the end of the fit-
tings. Replace hose if cuts are found
Water
Tank
Check condition of filter in water tank. Clean as needed.
Empty the water tank to prevent mildew and bacteria growth. Empty tank
by dipping the vacuum hose into the water tank and transferring the water
to the vacuum tank.
Vacuum Tank
Empty and flush vacuum tank.
Clean and disinfect.
Check the float shutoff screen to be sure it is not plugged up. A plugged
filter screen restricts airflow and results in reduced suction.
Leaks
Be alert for leaks around hoses, fittings, spray wand, tanks or elsewhere.
Discontinue use until leaks are repaired
Electrical System
The ground fault circuit interrupter (GFCI) must be tested before each use.
Electric cord must be inspected for tears or cuts in the insulation.
Vacuum Wand
Use a wire brush or coarse brush with acid cleaner or other to remove resi-
due from threads on the coupling and coupling nut. Apply grease when
done.
HEPA Filter
Replace every 3-6 months depending on use
Item
