:

To reduce the risk of fire, electric shock or injury;

Read all instructions before using this floor machine.

When using this floor machine, basic precautions should always be followed, including the following:

1) DO NOT leave this machine plugged in when not in use. Unplug from outlet when not in use and/or before servicing.

2) Electric shock could occur if exposed to rain. Store indoors.

3) This is NOT a toy. Close attention is necessary when used around or near children.

4) Use only as described in this manual.

Use only manufacturer's recommended attachments.

5) DO NOT use with damaged cord plug.

If the floor machine is not working as it should because it has been dropped, damaged, left outdoors, or dropped into water, contact the manufacturer or authorized service center.

6) DO NOT pull or carry by cord, use power cord as a handle, close a door on cord, or pull cord around sharp edges or corners.

DO NOT run floor machine over the cord.

Keep cord away from heated surfaces.

7) DO NOT handle the plug or operate with wet hands.

8) DO NOT put any object into the motor openings.

9) DO NOT unplug by pulling on cord. To unplug, grasp plug, not the power cord.

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

11) DO NOT operate where oxygen or anesthetics are used.

12) DO NOT use around flammable or combustible liquids such as gasoline or use in areas where they may be present.

13) DO NOT use an extension cord unless absolutely necessary. If an extension cord is used, then wire size must be #14 gauge or thicker and should not exceed 50 feet in length. Use only a 3 wire grounded extension cord to ensure grounding protection.

14) Replace damaged or worn parts immediately with genuine original equipment parts to maintain safety and protect your limited warranty.

15) Floor sanding can result in an explosive mixture of fine dust and air. Use a floor sanding machine only in a well ventilated area.

ROUNDING

NSTRUCTIONS

This floor machine must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. This machine is equipped with a cord having an equipment-grounded plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances

If repair or replacement of the cord or plug is necessary, DO NOT connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

G

ROUNDING

M

ETHODS

D

ANGER

:

Improper use of the grounding plug can result in a risk of electrical shock.

This floor machine is for use on a nominal

120 volt circuit, and has a grounding plug that looks like the plug illustrated in (Fig A).

A temporary adaptor that looks like the adaptor illustrated in (Fig B & C) may be used to connect the plug to a 2-pole receptacle as shown in (Fig A) if a properly grounded outlet is not available.

The temporary adaptor should be used only until a properly grounded outlet (Fig A) can be installed by a qualified electrician. The green color rigid ear, lug, or like extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by the metal screw (Fig C).

W

ARNING

:

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 properly grounded.

DO NOT modify the plug provided with the machine. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.

NOTE: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code.

NSTALLATION

This floor machine is designed for many different floor cleaning applications. It is important to select the correct brush or floor pad depending upon the type of cleaning operation you are doing.

When using floor pads, to achieve the best results use clean pads and change them as they load up.

Brush/Pad Installation:

1) Unplug the power cable and LOCK the handle in the upright position.

2) Tilt the machine back until the handle is laying on the floor and underside of the machine is fully exposed.

3) Holding the pad driver/brush in both hands, straddling the motor with your back to the handle, bend over and fit the three slots of the clutch plate over the three lugs of the drive plate.

4) Turn the brush counterclockwise as far as it will go. It is now seated and ready for operation

Note: The brush/pad surface should be flat and level on the floor.

Brush/Pad Removal:

Disengage clutch plate slots from drive plate lugs by turning clockwise.

C

AUTION

:

DO NOT leave a plugged in floor machine unattended.

Always unplug the machine before leaving to prevent accidental startup.

This floor machine is designed to move from side to side. Begin operating at the closest possible point to an electrical outlet and work away from the outlet. This will prevent running over the electrical cord.

Note: Before installing the brush/pad driver, plug in the machine and make sure the motor is only running when the triggers are activate and not before.

Setup for operation:

1) Install pad driver/brush (see instruc-

tions above) and plug in power cable.

2) Adjust the handle by pulling up on the clamping lever located at the rear of the machine.

3) Pull the handle toward you until you reach a comfortable operating position.

3) To move unit forward or backward, keep brush/pad surface flat on the floor and push or pull machine in the direction required.

4) To stop the floor machine, release triggers.

To begin operating:

1) To move unit right, slowly apply slight upward pressure. As the handle is raised higher, the faster it will move to the right.
