When using an electrical appliance, basic precautions
should always be followed, including the following:
READ ALL INSTRUCTIONS BEFORE USING THIS FLOOR
CLEANING MACHINE.
WARNING
To reduce the risk of fire, electric shock, or injury:
• Your machine is equipped with a safety switch lock
and power switch triggers designed for your safety.
Do not attempt to bypass or defeat the safety switch
lock. Never use any device to lock the power switch
triggers in the “ON” position.
• Do not leave the floor machine when plugged in.
Turn off the switch and unplug the electrical cord
when not in use and before servicing or changing
the brushes or pads.
• Do not allow the machine to be used as a toy. Close
attention is necessary when used near children. Do
not leave the machine connected to an electrical
outlet unattended.
• Use only as described in this manual. Use only
manufacturer’s recommended attachments.
• Do not use with a damaged cord or plug. If the
machine is not working as it should, has been
dropped, damaged, or left outdoors, return it to a
service center before using.
• Use care to keep the electrical supply cord from
contacting the rotating brush or drive block.
• Do not pull, close a door on, or pull the cord around
sharp edges or corners. Keep the cord away from
heated surfaces.
• Connect to properly grounded (3-wire) outlet only.
Refer to Grounding Instructions.
• Do not use extensions cords or outlets with
inadequate current-carrying capacity.
• Turn off all controls before unplugging.
• Do not unplug by pulling on cord. To unplug, grasp
the plug, not the cord.
• Do not handle the plug or floor machine with wet
hands.
• Wind the cord no tighter than is necessary to retain it
during storage. Refer to Cord Storage, Page 7.
• Use extra care when working near stairs.
• Do not use in conjunction with flammable or
combustible liquids such as gasoline; or use in areas
where explosive vapor or dust may be present.
• Store your floor machine indoors in a cool, dry area.
• Keep your work area well lighted.
• Warning – To avoid electrical shock, use indoors
only.
SAVE THESE INSTRUCTIONS
GENERAL INFORMATION
Use the floor cleaner to pick up dirt and dust particles.
Avoid picking up hard or sharp objects that could
damage the floor cleaning machine.
DO NOT OIL the motor or the brush drive. The
motor and brush drive are permanently sealed
and lubricated.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should
malfunction or breakdown, 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 plugged into
an appropriate outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
IMPORTANT SAFEGUARDS

PAGE 3 OF 7 0421 IH-1630
DANGER
Improper connection of an equipment-grounding
conductor can result in 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 proper outlet installed by a
qualified technician.
This appliance is for use on a nominal 120 volt circuit
and has a grounding plug that looks like the plug
illustrated in Figure 1. A temporary adapter which looks
like the adapter illustrated in Figure 2 may be used to
connect this plug to a two-pole receptacle, as shown,
if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet, Figure 1, can be installed by a
qualified electrician. The green colored rigid ear, lug, or
the like extending from the adapter must be connected
to a permanent ground such as a properly grounded
outlet box cover. Whenever the adapter is used, it must
be held in place by a metal screw.
For floor finishing machines rated 150–250 volts:
If the machine is provided with an attachment plug
cap as shown in Figure 3, it is intended for use on a 240
volt (nominal) circuit. No adapter is available for this
application.
NOTE: In Canada, the use of a temporary
adapter is not permitted by the Canadian
Electrical Code.
OPERATION/ACCESSORIES
CHOOSING THE RIGHT BRUSH AND DRIVE BLOCK
Your floor machine is packed complete and ready for
use after you install a brush or drive block. (Brushes and
pads are not provided with the unit but are available at
an additional cost.)
Your floor machine is designed to be used for many
different floor care applications. Make sure you use
the correct brush or pad for the type of job you want to
perform. (Accessories are available from the dealer from
whom the floor machine was purchased.)
When ordering brushes or drive blocks, refer to this
chart and specify correct brush or block diameter when
ordering.

BRUSH AND PAD DRIVER INSTALLATION
CAUTION: Disconnect the power cord from the
electrical outlet before installing a brush or pad
driver.
To install a brush or pad driver, leave the handle in the
upright position and tip the machine backwards so it rests
on its wheels and upper handle section. (See Figure 4) The
brush and pad driver both attach in the same manner:
align the cutouts on the inner ring of the brush or pad
driver with the tabs on the inside of the ring of the drive
hub. (See Figure 5) Push the brush or pad driver firmly in
position, then turn it counterclockwise until it locks into
place.
To remove, turn the brush or pad driver clockwise until
it stops, then lift it off. Note: Always remove the brush
or pad driver when the
machine is not in use.
CAUTION:
Disconnect the
power cord from
the electrical
outlet before
installing a brush
or pad driver.
HANDLE ADJUSTMENT
The handle can be adjusted to any desired work
position by simply pushing up on the handle lock. (See
Figure 6) Move the handle to the desired position, then
firmly push down on the handle lock which will lock the
handle in position.
HANDLE CAM LOCK ADJUSTMENT
With the handle cam lock in the “up” position
(unlocked), tighten the adjusting nuts until there is a
slight drag when the handle is raised or lowered. The
tube should be locked securely when the handle lock is

CONTROLS
ON/OFF POWER SWITCH TRIGGERS
The ON/OFF switch is conveniently located in the form of
dual triggers underneath the handle grips.
TO TURN THE MACHINE ON
The operating handle must be lowered to the operating
position before switching the machine ON. Place
both hands firmly on the handle grips with your fingers
around the power triggers. Do not apply pressure on the
triggers before the safety switch lock is disengaged.
Disengage the safety switch lock by pushing it forward
with one thumb. (See Figure 8) Then, while holding the
safety switch lock in disengaged position, squeeze the
power triggers toward the handle grips and return your
thumb to the handle grip.
To stop the machine, simply release the triggers.
The safety switch lock will automatically return to the
engaged position.
GUIDELINES FOR OPERATION
• Your floor machine is a very sensitive, powerful unit.
When in operation, it should be guided gradually
and smoothly without sudden or rough motions. You
will want to practice with your machine on a smooth
surface first until you have experience in operating it.
• For ease of operation, always keep the brush or pad
surface level, balanced and flat on the floor at all
times.
• Always adjust the operating handle to a comfortable
height at which the brush or pad surface is
balanced before starting the machine. (see “Handle
Adjustment” Page 5)
• Your floor machine will operate differently on various
surfaces. For example, there will be much more
resistance when the machine is used with a brush
on carpeted surfaces than when it is used with a
pad on a smooth surface. The operator should be
prepared to adjust for these differences.
BEGIN OPERATING THE FLOOR MACHINE WITH THE
BRUSH OR PAD SURFACE LEVEL, BALANCED AND
FLAT ON THE FLOOR.
• To move the machine to the right, slowly apply slight
upward pressure on the handle.
• To move the machine to the left, slowly apply slight
downward pressure on the handle.
• To move the machine forward or backward, keep
brush or pad flat on the floor and push or pull
machine in the desired direction.
DO NOT LET THE MACHINE REST ON THE PAD OR
BRUSH FOR AN EXTENDED PERIOD OF TIME. This
may alter the shape of the pad or brush which
may cause the machine to wobble.

CORD STORAGE
When not in use, loosely wind the power cord around
the cord storage hook on the handle shaft and both of
the handle grips. (See Figure 9)
CLEAN UP AND STORAGE
After being used, your floor machine can be wiped
clean with a soft, damp cloth and should be stored in a
clean, dry place.
