SCRUB SWITCH
The scrub switch controls the scrubbing
operations. The scrub switch also sets the scrub
brush pressure.
The scrubbing operations include the following.
The scrub head lowers and the brushes turn on.
The rear squeegee will lower and the vacuum fan
will start. The solution system will start, if the
solution flow switch is on. The FaST system or
optional ES system and detergent pump will start,
if the switches are on. The optional side brush will
lower and turn on, if the side brush switch is on.
The engine speed will change to (Fast).
NOTE: The brush pressure setting, the FaST
system, the detergent flow rate, the side brush,
and the ES system will default to the last setting
used when the scrubbing operations are started
again.
Start: Press the scrub switch. The indicator light
above the switch will come on.
Stop: Press the scrub switch. The indicator light
above the switch goes off.
Scrub brush pressure: Press and hold the scrub
switch. The brush pressure will scroll through the
three settings. The pressure setting selected
when the switch is released, will be the new
default brush pressure setting.
The brush pressure has three positions. Under
normal conditions, the brush pressure should be
set in the minimum setting. Under heavy grime
conditions, the brush pressure should be set in
the maximum setting. Travel speed and floor
conditions will affect the scrubbing performance.
NOTE: The scrub head and squeegee will raise
when the machine travels in reverse.
