Safety
Electrical
The amp, hertz, and voltage are listed on the data label
found on each machine. Using voltages a bove or below
those indicated on the data label will cause serious
damage to the motors.
Extension Cords:
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check
with a qualified electrician or service person if you are
in doubt as to whether the outlet is properly grounded.
Do not modify the plug provided with the appliance - if it
will not fit the outlet; have a proper outlet installed by a
qualified electrician.
Grounding Instructions:
This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and
grounding plug. The plug must be inserted into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Le raccordement incorrect du conducteur de terre
d'équipement peut entraîner des risques d'électrocution. Vérifiez auprès d'un électricien qualifié ou d'un
responsable de l'entretien si vous avez quelque doute
que ce soit quant au raccordement à la terre de votre
prise murale. Ne modifiez pas la fiche fournie avec
l'appareil : si elle ne correspond pas à la prise murale,
faites installer une prise adéquate par un électricien
qualifié. Utilisez-le uniquement sur des réceptacles
protégés GFCI.

turn on brush and start solution spray.
The intermittent setting requires the operator to
hold the switch in the "on" position with the thumb,
and is typically used in small areas where short
cleaning passes are made.
The continuous setting allows the operator to set
the switch in the "on" position with one touch, and
is typically used in large areas where long cleaning
passes are made.
Cleaning Procedure
1. Start at wall closest to power outlet. Pull straight
back without pushing down on handle.

Maintenance
Periodic Maintenance
Twice a month, flush a white vinegar solution (One
quart vinegar to two gallons of water) or anti-browning
solution (mixed as directed) through the extractor. This
will prevent build-up of alkaline residue in the system. If
spray jets become clogged, remove the spray tips,
wash them thoroughly, and blow-dry.
NOTE: Do not use pins, wire, etc. to clean nozzles as
this could destroy spray pattern.
Periodically inspect all hoses, electrical cables and
connections on your machine. Frayed or cracked hoses
should be repaired or replaced to eliminate vacuum or
solution pressure loss. If the cable insulation is broken
or frayed, repair or replace it immediately. Don't take
chances with electrical fire or shock.
Daily / Regular Maintenance
Before making any adjustments or repairs to the
machine, disconnect the power cord from electrical
source.
9. Check float and shut-off screen and clean as
necessary.
NOTE: Always store machine with brush in "Store"
position.
1. Empty unused cleaning solution from the solution
tank.
2. Inspect and clean filter screen in solution tank.
3. Flush pumping system with 4 or 7 liters of clean,
hot water.
4. After each use, rinse tank with fresh water. Periodically inspect the recovery tank and decontam inate
if necessary, using a Hospital Grade Virucide or a
1-10 bleach to water solution. Waste water should
be disposed of properly.
5. Check for and remove any lint or debris around
vacuum shoe.
6. Check spray jets for full spray pattern.
7. Remove lint and dirt build-up from brush an d
housing.
NOTE: Brush removal.
