IMPORTANT SAFETY INFORMATION
Grounding Instructions
This machine must be grounded. If it should malfunction
or breakdown, grounding provides a path of least resis-
tance for electrical shock. This machine is equipped with
a cord having an equipment-grounding conductor and
grounding plug. The plug must be plugged into an appro-
priate outlet that is properly installed in accordance with
all local code and ordinances. Do not remove ground pin;
if missing, replace plug before use.
Improper installation of the equipment-grounding conduc-
tor can result in a risk of electric shock. Be sure to check
with a qualied electrician or service person if you are in
doubt as to whether the outlet is properly grounded. If
the plug will not t in the outlet do not modify either the
plug nor the machine’s cord, instead have a proper outlet
installed by a qualied technician.
This machine is for use on a nominal 120-volt circuit and
with a grounding plug similar to the one in Figure 1 below.
If a proper outlet is not available, follow the illustrations of
Figure 2 & 3 to install a temporary-grounding plug. This
temporary work-around should be used only until a proper
outlet (Figure 1) can be installed by a qualied electrician.
When and if this type of adapter is employed, screw the
adapter’s extended tab into place with a metal screw.
However, grounding adapters are not approved for use in
Canada.
Again, be sure to check the grounding pin for damages
and replace if necessary.
The Green, or Green-Yellow, wire in the cord is the
grounding wire. When replacing a plug, this wire must be
attached to only the grounding pin.
DO NOT use extension cords.
Please Note for America use only.
Parts and Service
Please contact a Mytee service personnel or Mytee
authorized Service Center using Mytee original replace-
ment parts and accessories for repairs are needing to be
performed. When and if calling Mytee for support, please
have your Model and Serial Number available for faster
assistance.
Name Plate
The Model and Serial Number are located on the lower
half of the back of the machine near the power plugs and
will be required for ordering replacement parts. You can

down both for future referencing.
Unpacking the Machine
When your new machine is delivered, please carefully in-
spect both the shipping carton and the machine for dam-
ages. If damage is evident, save both the shipping carton
and machine so that the delivering carrier can inspect it.
Contact the carrier immediately to le a freight claim if
there has been any damage.

driver onto a 17” cleaning pad. Make sure the pad is as
centered as possible on the pad driver with no driver bris-
tles exposed to carpet. ♦
2.3 - Filling the Shampoo Tank

3 - BATTERY INFORMATION
3.1 - About the Battery
There are two batteries supplied with your machine and
a charger. Under normal use, the batteries will run the
machine for about an hour. The battery charger will also
charge the batteries in less than 1 hour. You can have
one battery on your machine to run it while the other is
charging. In this way, you can keep your machine running
continuously. ♦
3.2 - The Battery Panel
On the Battery Panel:
1. Circuit Breaker - The circuit breaker will pop out when
the current drawn from the battery exceeds 30A. Currents
exceeding 30A can occur when the brush (or pad) gets
stuck, too much pressure is applied, or the surface has
too much resistance. If this should happen, simply wait 3
minutes and push the button labeled “30” back in. Your
machine will be ready for use.
2. Factory Service Connector - The factory service
connector is for performing initial calibration of the battery
management computer inside the battery pack. It is for
use only at the factory.
3. Charge Display - The charge display will tell you how
much charge is still in the battery, just like the gas gauge in
your car tells you how much gas is left. ♦
3.3 - About the Battery Charger
To charge the battery, rst plug the battery into the char-
ger and then plug the charger into a wall outlet. The fan in
the charger will start and the LEDs will go on both on the
charger and on the battery’s charge display.
Battery Charger Display:
When the charger is plugged in and charging the batter-
ies, the column of green LEDs will light one on top of the
other. When the battery is low the rst green LED will ash,
indicating that the battery is less than 20% charged. When
the battery reaches 20%, the 20% light will stay on and
the 40% light will ash. This will continue until the battery
reaches 100% and all the LEDs will be lit. The fan will usu-
ally turn o when the battery is charged, however it is not
sign of a problem if the fan stays on. ♦

15
4 - MACHINE MAINTENANCE
1. Remove the pad driver assembly
by removing the four bolts with a 7/16”
wrench or socket.
2. Hold the jam nut, located between
the ywheel and motor, in place with a
15/16” open-end wrench. Using a mal-
let, tap the ywheel counter-clockwise
to loosen.
3. Remove the plastic plug from the
top of the motor and hold the motor
shaft in place by inserting a athead
screw- driver into the top of the shaft
on top of the motor. Loosen the y-
wheel the rest of the way o with the
other hand.
4. Apply Anti-Sieze to the motor shaft.
To install the new ywheel, hold the
motor shaft in place with the athead
screwdriver just like before and thread
the new ywheel on with the other
hand until it stops at the jam nut.
5. Use the 15/16” wrench to hold the
jam nut in place and use a mallet to
strike the ywheel counterweight to
tighten the ywheel against the jam
nut.
6. Apply Blue Loctite®to the pad
driver bolts and bolt it back onto the
machine. ♦
4.2 - Flywheel Replacement
These instructions cover how to remove and replace the
