Important Safety Instructions
When using an electrical appliance, basic precautions should always be followed, including the following:
• Your Orbit 20 Pro Floor Finisher 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 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
heated surfaces.
• Connect to properly grounded (3-wire) outlet only. Refer to Grounding Instructions.
• Do not use extension cords or outlets with inadequate current carrying capacity.
• Turn off all controls before unplugging.
• Do not unplug by pulling on the cord. To unplug, grasp the plug and pull.
• Do not handle the plug or the machine with wet hands.
• Wind the cord no tighter than is necessary to retain it during storage. Refer to Cord Storage.

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.

Basic Operation
To turn the machine on, the operating handle must be lowered and locked to the proper operating position be-
fore switching the machine ON. Place both hands fi rmly on the handle grips with your fi ngers around the power

Disengage the safety switch lock by pushing it forward with one thumb. Then, while holding the safety switch
lock in the disengaged position, squeeze the power triggers toward the handle grips and return your thumb to

Guidelines for Operation
• Your Orbit 20 Pro Floor Finisher 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 until you have experience in operating it.
• For ease of operation, always keep the brush or pad surface level, balanced, and fl at on the fl oor 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 4)
• Your machine will operate diff erently on various surfaces. For example, there will be much more resistance
when the machine is used on a rough surface, than when it is used on a smooth surface. The operator should
be prepared to adjust for these diff erences.
• Begin operating the machine with the pad surface level, balanced, and fl at on the fl oor.
• To move the machine to the right, turn the unit to the right.
• To move the machine to the left, turn the unit to the left.
• To move the machine forward or backward, keep the brush or pad fl at on the fl oor and push or pull the ma-
chine in the desired direction.

Handle Adjustment
The handle can be adjusted to any desired work position by simply pulling on the pull pin and move the handle
to the desired position. Firmly push the pull pin back into the adjustment holes. This will lock the handle in
position.
