OPERATION
5. Pour a recommended foam control solution into
the recovery tank if excessive foam appears.
ATTENTION: Do not allow foam to enter the float
shut-off screen, vacuum motor damage will result.
Foam will not activate the float shut-off screen.
6. Use the double scrubbing method for heavily
soiled areas. First scrub the area with the
squeegee up, let solution set for 3--5 minutes, then
scrub the area a second time with the squeegee
down.
7. When leaving the machine unattended, park the
machine on a level surface and remove the key.
8. ec- H2O Model: If an alarm sounds and the
ec- -H2O system indicator light begins to blink red,
the ec- -H2O module must be flushed to resume
ec- -H2O operation (See ec- -H2O MODULE
FLUSH PROCEDURE) (Figure 23).
NOTE: When the alarm sounds and the light blinks
red, the machine will bypass the ec- -H2O system. To
continue scrubbing, turn the ec- -H2O switch off and
change over to conventional scrubbing.
ATTENTION: (ec- H2O model) Do not allow
solution tank to run dry. ec- H2O module failure
may result if operated without water for an
extended period.

10. Perform the Daily Maintenance procedures after
scrubbing (See MACHINE MAINTENANCE).
BATTERY METER
The battery meter displays the charge level of the
batteries. When the batteries are fully charged, all
indicator lights are lit. As the batteries discharge, the
indicator lights will begin to go out from right to left.
To prolong the life of the batteries, do not allow the
indicator lights to go beyond the discharge level as
described below.
NOTE: To prolong the life of the batteries ONLY
recharge the batteries when the machine is used for a
total of 30 minutes or more.
DRIVE MODEL: When the discharge level reaches
the first red light (Figure 25), stop scrubbing and
recharge the batteries. If the last red light begins to
flash, the scrubbing function will shut off automatically.
This protects the batteries from total discharge. Drive
the machine to the charging area and recharge the
batteries immediately.
NOTE: The Drive Model battery meter also displays
machine fault codes. If a fault is detected, the LED
bars will flash specific fault codes (See BATTERY
METER LED FAULT CODES).
