IMPORTANT SAFETY INSTRUCTIONS

FOR COMMERCIAL USE

WHEN USING AN ELECTRICAL APPLIANCE, BASIC PRECAUTIONS SHOULD

ALWAYS BE FOLLOWED INCLUDING THE FOLLOWING:

READ ALL INSTRUCTIONS BEFORE USING THIS MACHINE

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY:

Do not leave machine when plugged in. Unplug from outlet when not in use and before changing
pads or attempting any maintenance or adjustment. If handle switch lever is activated
accidentally, high starting torque will cause machine to move and may cause damage or injury.

To avoid electrical shock, Use indoors only. Do not use outdoors and do not expose to rain.

Do not allow to be used as a toy. Close attention is necessary when used by or near children.

Use only as described in this manual. Use only manufacturer’s recommended attachments.

Do not use with damaged cord or plug. If machine is not working as it should, has been dropped,
damaged, left outdoors, or dropped into water, return it to a service center.

Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around
sharp edges or corners. Do not run machine over cord. Keep cord away from heated surfaces.
Do not unplug by pulling on cord. To unplug, grasp the plug not the cord. Do not handle plug or
machine with wet hands.

Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.

Turn off all controls before unplugging.

Connect to a properly grounded outlet only. See Grounding Instructions.

Do not put hands under base - rotating parts could cause injury. Always keep hands feet and
loose fitting clothing away from moving parts to prevent possible injuries. Use care to keep
electrical supply cable from contacting moving parts, such as floor brushes or pads.

Risk of explosion: Floor sanding can result in explosive mixture of fine dust and air. Use this
machine only in a well-ventilated area, free from any flame or match. Do not use machine in
areas where flammable and/or explosive vapors or dust are present. To avoid fires do not use
with a flammable or combustible liquid to clean a floor.

Make sure voltage and frequency at the wall receptacle correspond with that indicated on
nameplate before plugging in machine. A 20-amp circuit is recommended. Right or left switch
levers will independently operate the motor.

Never use a device to lock the switch lever in the “ON” position.

Use only a 12 Ga. three-wire extension cable, which have 3-prong grounding type plugs and 3­prong receptacles that accept the plug of the machine.

Do not add weight to this machine - this will upset the balance and may cause motor overload.

Do not hop the brush or pad holder onto the machine.

GROUNDING INSTRUCTIONS

This appliance must be grounded. If it should malfunction or breakdown, of grounding provides a
path of least resistance for electric current to reduce the risk electric shock. This machine 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.

WARNING: Improper connection of the equipment-grounding conductor can
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.

This appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the
plug illustrated in sketch A. A temporary adapter that looks like the adapter illustrated in sketches B
and C may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a properly
grounded outlet is not available. The temporary adapter should be used only until a qualified
electrician can install a properly grounded outlet (sketch A). The green-colored rigid car, 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.
