To reduce the risk of fire, electric shock, or injury:
 Do not allow to be used as a toy. Close attention is necessary when used by or near children.
 Do not handle plug or appliance with wet hands.
 Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
 Do not use with damaged cord or plug. If appliance is not working as it should, has been dropped,
damaged, left outdoors, or dropped into water, return it to a authorized service center.
 Do not pull or carry by cord, use cord as a handle, close a door on a cord, or pull cord around sharp
edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.
 The machine was designed for the use as per instructions and recommendations written in this man-
ual. Any deviation from its proper use or purpose and the consequential damage that may occur is
the sole responsibility of the end user.
 Use only manufacturer’s recommended attachments.
 Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint,
hair, and anything that may reduce air flow.
 Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.
 Do not operate machine in flammable or explosive areas.
 Turn off all controls before unplugging.
 When servicing machine, use only manufacturer’s replacement parts. All service should be per-
formed only by General Floorcraft authorized service centers.
 Use extra care when cleaning stairs.

ing as shown on the nameplate of the machine. Do not attempt to plug a 115-volt machine into a 230-
volt outlet.

SAFETY & GROUNDING INSTRUCTIONS
WARNING!
 DO NOT use extension cords more than 50 feet (15 m) long.
 Replace the cord if the ground pin is damaged or broken.
FAILURE TO COMPLY WITH THE ABOVE WARNING INSTRUCTIONS WILL
VOID THE WARRANTY.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should electrically malfunction, 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 with all local codes and ordinances.
DANGER!
Improper connection of the equipment-grounding conductor can result in a risk of electrical shock.
Check with a qualified electrician or service person if you are in doubt as to whether the outlet is prop-
erly grounded. Do not modify the plug provided with this 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 Figure 1 below.

ASSEMBLY & OPERATION INSTRUCTIONS
PREPARE THE MACHINE FOR OPERATION (SETTING UP)
The 2000 DC-4 machine is packed in two separate boxes. The machine is in box 1 of 2, and the handle is
in carton 2 of 2. Unpack the machine and handle carefully. Insert the handle into the handle adaptor
socket and tighten the two square head screws to hold the handle firmly in place. DO NOT OVER-
TIGHTEN SCREWS. Damage could occur to the handle adaptor threads and will cause the handle to
be loose and unsafe. Connect the male motor lead from motor to the female handle lead from handle.
PAD INSTALLATION:
WARNING: Make sure the power cord is disconnected from the electrical outlet before installing or re-
moving the pads from machine.
1.) The proper diameter pad is 20” although 21” can be used, but greater care must be used not to hit
walls, baseboards or furniture.
2.) Unwrap the power cord from handle. Do not plug cord into wall outlet. Lock the handle in the up-
right position. Tilt the machine back on the wheels and handle so that the machine is resting on han-
dle and the bottom of machine is up in the air. Remove pad centering ring and install pad over the
pad holder. Install pad centering ring.
3.) Lower the machine carefully to the floor with the handle still in the vertical position.
4.) To remove pad, unwrap the power cord from handle. Do not plug cord into wall outlet. Lock the
handle in the upright position. Tilt the machine back on the wheels and handle so that the machine is
resting on handle and the bottom of machine is up in the air. Remove pad centering ring. Remove
pad and replace pad centering ring.
HOW TO OPERATE MACHINE
1.) Unwrap the power cord. Do not plug in yet.
2.) Install the pad.
3.) Lower handle by pressing foot release first. Handle will now float up or down until it rests on the
stop at base of machine. Slightly press down on the handle to relieve floor pressure. Press the mo-
mentary safety switch at the right or left side of handle. While walking forward slowly lower ma-
chine to the floor to start burnishing.
4.) Plug in cord into a properly grounded outlet.
5.) Place both hands on the handle grips with your fingers around the on/off levers which extends from
one side to the other side underneath the hand grips.
WARNING!
Be prepared to control the machine as soon as the motor starts.
