GROUNDING INSTUCTIONS-120V
THIS PRODUCT IS FOR COMMERCIAL USE
ONLY.
ELECTRICAL:
In the USA this machine operates on a one 15
amp nominal 120V, 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 120-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.
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.

The machine is shipped with handle unassembled.
Follow these steps for installation:
1. Remove handle and deck assembly from carton.
2. Attach handle assembly to base using hardware kit (86219680-PRV NO. 47331) (attached to handle in a
plastic bag) items 1, 2, and 3.
NOTE: The spacers (items 1) are required for the correct operation of the handle. The spacers are
positioned completely inside the pivot holes in the casting, and are held in place by tightening the
bolts and washers (items 2 and 3) against the spacer.
3. Remove bolt, nut and washers (items 4, 5 and 6) from lower block on handle assembly. Attach links as
shown. Tighten bolt and nut securely, then back off 1/4 to 1/2 turn.
4. Check handle for movement up and down.
5. Plug motor cord into handle cord receptacle.

CONTROLS
1. Safety Lock – Prevents unintended operation
of the machine.
2. Switch Levers – Turns machine on/off.
3. Adjustment Handle – Allows the handle to be
adjusted to a comfortable operating position.
HANDLE HEIGHT ADJUSTMENT
NOTE: The handle is in the up, locked
position from the factory.
The handle adjust bar (1) for the polishers are
individually preset at the factory for optimum
locking efficiency and minimum effort of
engaging. It should not be necessary to adjust
the handle adjust bar unless the handle
adjustment bar (1) the washer (3) and nut (2)
have been disturbed.
NOTE: It is incorrect to make it lock
opposite from the way it was assembled by
applying more force to the nut.
The pivot pin is off center in relationship to the
axis of the handle. To adjust handle, tighten
nut on handle while in the locked position. The
handle is locked when the screw is to the
outside of the machine and the flat on the
opposite side of the handle is flush to the
bracket.

MACHINE OPERATION
For indoor use only.
When using the pad, always keep the machine
moving when in contact with the floor.
High starting torque. Hold machine firmly with
both hands.
1. Ensure that the pad driver is in good shape.
Install or change pad if necessary.
2. Plug the machine into a wall outlet as
described in the grounding instructions.
3. Lower the handle by unlocking the adjustment
handle and moving the handle into position.
Relock the handle when it is in a comfortable
position.
Insure that handle is locked in position before
starting machine.
4. Push the safety lock forward, unlocking the
switch levers.
5. With the safety lock forward, squeeze one or
both of the switch levers, turning the machine
on. (These levers can be operated
independently of each other). The safety lock
will not re-engage until both levers are
released.
6. To stop the machine, release the switch
levers.
7. Do not let machine rest on pad. When
finished with the machine, return handle to the
storage position.
NOTE: The machine is equipped with a circuit
breaker to protect the motor in the event an
overload condition occurs. The circuit breaker
is located on the handle. Push the reset button
to restart the machine. If the breaker trips
again, correct the cause of overloading before
proceeding.
DAILY MAINTENANCE
1. Inspect power cord for wear. To prevent
electrical shock replace cords with frayed or
cracked insulation immediately.
2. Place machine in the storage position.
3. Check pad condition. Change if soiled or torn.
PAD DRIVER/BRUSH INSTALLATION
1. Lay machine back, exposing the under
side.
2. Place pad driver on the motor lug and
rotate counter-clockwise until engaged. To
remove, turn clockwise.

SCRUB BRUSHES
NOTE: All original equipment brushes are
equipped with “Perform Alert©”. This feature will
tell the operator when it is time to replace the
scrub brushes. “Perform Alert©” brushes have
pre-trimmed bright yellow tufts to indicate the
length of a worn out brush. When the tufts in the
scrub brush wear to a length equal to the yellow
tufts, the scrub brushes should be replaced.
There are five different types of brushes available
to cover applications from cleaning heavily soiled
floors to polishing. A pad driver is also available to
take advantage of the many cleaning pads on the
market and further add to the flexibility of the
machine.
Please refer to the following to assist in selecting
the proper brush or pad for the work at hand.
UNCOATED FLOORS
Aggressive Grit is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
Mild Grit is a less aggressive silicone carbide grit
suitable for cleaning medium soil conditions.
Advantages are faster ground speed than nylon
bristles on light solid applications.
Nylon is a general-purpose scrub brush with stiff
bristles. Polypropylene works well for maintaining
concrete, wood and tile floors.
FINISHED FLOORS
Nylon Polish is the softest brush. It will gently
clean finished tile or terrazzo floors without
removing floor finish or floor material. Used for
washing highly polished or burnished floors.
Nylon bristles are used in a variety of applications
on coated or uncoated surfaces.
White Pads (Polishing) are used for dry polishing
to achieve a high-gloss appearance, or surface
washing on highly polished or burnished floors.
Red Pads (Buffing) are used for light-duty
scrubbing. When used with a mild detergent they
will provide surface cleaning without removing the
finish.
Blue Pads (Scrubbing) are used for heavy-duty
scrubbing and light stripping. The blue pads
remove less finish than brown stripping pads, yet
will remove black marks, stains and dirt.
Brown Pads (Stripping) are used for easy and
complete removal of old floor waxes/finishes.
They will quickly remove ground in dirt, black heel
marks, and spills. When used with the proper
stripper, this pad leaves the floor clean and ready
for finishing.
The scrub brushes should be checked before each
days work for wire, string, wear and damage. The
scrub brushes should be replaced if brush bristles
are missing or if yellow Perform Alert ©indicates
minimum brush length.
