HAZARD INTENSITY LEVEL
CADET 86038220 03/16/07
2-2
The following symbols are used throughout this guide as indicated in their descriptions:
HAZARD INTENSITY LEVEL
There are three levels of hazard intensity identified by signal words -WARNING and CAUTION and FOR
SAFETY. The level of hazard intensity is determined by the following definitions:
!WARNING
WARNING - Hazards or unsafe practices which COULD result in severe personal injury or death.
!CAUTION
CAUTION - Hazards or unsafe practices which could result in minor personal injury or product or property
damage.
FOR SAFETY: To Identify actions which must be followed for safe operation of equipment.
Report machine damage or faulty operation immediately. Do not use the machine if it is not in proper
operating condition. Following is information that signals some potentially dangerous conditions to the
operator or the equipment. Read this information carefully. Know when these conditions can exist. Locate
all safety devices on the machine. Please take the necessary steps to train the machine operating
personnel.
FOR SAFETY:
DO NOT OPERATE MACHINE:
Unless Trained and Authorized.
Unless Operation Guide is Read and understood.

THIS PRODUCT IS FOR COMMERCIAL USE ONLY.
ELECTRICAL:
In the USA this machine operates on a standard 15
amp 115V, 60 hz, A.C. power circuit . The amp,
hertz, and voltage are listed on the data label found
on each machine. Using voltages above or below
those indicated on the data label will cause serious
damage to the motors.
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.
This appliance is for use on a nominal 115-volt circuit,
and has a grounded plug that looks like the plug in
“Fig. A”. A temporary adaptor that looks like the
adaptor in “Fig . C” may be used to connect this plug
to a 2-pole receptacle as shown in “Fig. B”, if a
properly grounded outlet is not available. The
temporary adaptor should be used only until a
properly grounded outlet (Fig. A) can be installed by a
qualified electrician. The green colored rigid ear, lug,
or the like extending from the adaptor must be
connected to a permanent ground such as a properly
grounded outlet box cover. Whenever the adaptor is
used, it must be held in place by a metal screw.
WARNING:
!
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.

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.

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.
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
decontaminate 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
vac shoe.
6. Check spray jets for full spray pattern.
7. Remove lint and dirt build-up from brush and
housing.
NOTE: Brush removal.
A. To remove brush, grab and pull brush out
from end opposite drive belt (operator’s
right). Remove other end from brush driver.
B. To install brush, line up slots in brush core
with pin in driver on drive belt side
(operator’s left) and push brush onto driver.
Then snap bearing end (opposite end) of
brush into retaining clip.
8. Check cooling air screen (located on frame
behind left wheel) for lint or debris.
9. Check float and shut-off screen and clean as
necessary.
NOTE: Always store machine with brush in “Store”
position.

Carbon
Brushes
If armature commutator is grooved, extremely pitted or not

Important:
These brushes wear quicker as the length shortens due to
increased heat. Spring inside brush housing will damage
motor if brushes are allowed to wear away completely.
Periodically check the length of the carbon brushes. Replace
both carbon brushes when either is less than 3/8" (9.5mm)
long.
