Maintenance
Daily
▪
Inspect the DuoScrubber® HP Assemblies overall; for damaged or missing foam on clean
heads, loose bolts that may cause wobbling, and worn bearings.
Monthly
▪
Inspect cleaning foam on all cleaning heads for wear or damage, replace as needed.
▪
Grease arm pivot bearings (4 per side) using marine grease.
Note:
Before GREASING and after GREASING wipe off all bearing seal surfaces and Zerks. Grease
should only be applied until water is pushed out and bearings seals start to swell.
Note:
The bottom bearings are accessible to be wiped clean, however the upper bearings are not,
access the top bearings by removing the bolt on top of the utility weldments.
▪
Apply Fluid Film Rust and Corrosion Preventative spray liberally to all arm pivot bearings
(4 per side).

Cleaning head stalls

•
Pressure of Regulators
on the Air Panel are set
too high
•
Check pressure on regulator from air control
panel. If the regulated pressure is too high, it
may cause head to stall. Release pressure by
turning knob counterclockwise until stalling
halts. Be sure that there is still enough pressure
to allow the heads to rotate smoothly.
Cleaning heads not
spinning
•
Mechanical failure may
be possible

Check to see if bearings are seized up. If so,
see replacement parts.

Check electrical signal
•
