DRAINING SOLUTION TANK

To drain leftover cleaning solution from solution tank,
perform the following steps:
1. Pull the clear hose off hose barb at rear of
machine and drain solution into floor drain or
bucket (Figure 20).
FIG. 20
2. Rinse out solution tank and solution flow system
with clean water after each use. This will prevent
clogging due to chemical buildup.
3. Reconnect solution tank drain hose securely after
draining.

ADJUSTING BRUSHES

On a monthly basis or after installing new brushes,
check the brush pattern to ensure brushes are
properly adjusted. Brushes that are installed
improperly will result in premature brush wear and
poor scrubbing performance.
NOTE: If machine is equipped with air–filled tires, fill
solution tank before checking or adjusting brushes.
1. Apply a powdered substance, such as chalk, on a
smooth, level floor.
2. With scrub head raised, position scrub head over
test area.
3. Place blocks behind each drive wheel to keep
machine stationary and turn speed control knob to
slowest setting.
4. Lower scrub head to floor and apply maximum
down pressure.
5. Make sure that the solution switch is in the OFF
position.
6. Briefly rotate control grips forward for 2 seconds.
7. Raise scrub head and reverse machine from test
area.
