Important Safety Instructions
When using an electrical appliance, basic precautions should always be followed, including the following:
• Your Orbit 20/28 Pro Floor Finisher is equipped with a safety switch lock and power switch triggers de-
signed 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 machine 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, dam-
aged, or left outdoors, return it to a service center before using.
• Use care to keep the electrical supply cord around sharp edges or corners. Keep the cord away from the

Grounding Instructions
This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least re-
sistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord that has
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.
Improper connection of an equipment grounding conductor can result in risk of electric shock. Check
with a qualifi ed 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 fi t the outlet, have a proper outlet installed
by a qualifi ed electrician. 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.
