CYLINDRICAL BRUSH MODEL
After installing a new set of cylindrical brushes check
the brush pattern to ensure proper brush adjustment.
Brushes that are not properly adjusted will result in
premature wear and poor scrubbing performance
(Figure 55).

To Inspect the Brush Pattern:
1. Position the machine on a dry dusty floor or apply a
powdered substance, such as chalk.
2. Disconnect the drive motor wire connector to keep
machine from moving forward (Figure 56).

3. Lower the scrub head to the floor and apply
maximum brush pressure.
4. Shut off the solution flow.
5. Pull the control handle bail to create a brush
pattern on the floor.
6. Raise the scrub head and pull the machine away.
7. Observe the brush pattern on floor . If the brush
pattern is uneven or tapered, adjustment is
required.
8. Reconnect drive motor wire.
To Adjust an Uneven Brush Pattern:
Tools required: Measuring device, 27mm wrench and
24mm wrench
1. Measure the distance from the front edge of the
scrub head to the floor and from the back edge of
the scrub head to the floor (Figure 57). The
measurements should be the same.
