WHILE OPERATING MACHINE
WARNING: Fire Or Explosion Hazard. Do Not
Pick Up Flammable Materials Or Reactive Metals.
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces. Wear non--slip
shoes.
1. Overlap each scrubbing path by 2 in / 5 cm.
2. Keep the machine moving to prevent damage to
floor finish.
3. Wipe the squeegee blades with a cloth if blades
leave streaks. Pre-sweep the area to prevent
streaking.
4. Do not operate the machine on inclines that
exceed 5%.
5. Conventional scrubbing: Pour a commercially
approved 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. For heavily soiled areas, use the double scrubbing
method. 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, remove the
key and set the parking brake, if equipped.
8. If the machine detects a fault, the battery meter will
blink a fault code (See BATTERY METER LED
FAULT CODES on page 27).
9. 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 21).
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
