Electrical Requirements

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool's plug.*

Repair or replace a damaged or worn cord immediately.

This tool is intended for use on a circuit that has an outlet that looks the one illustrated in Figure A below. The tool has a grounding plug that looks like the grounding plug as illustrated in Figure A below. A temporary adapter, which locks like the adapter as illustrated in Figure B below, may be used to connect this plug to a two-pole receptacle, as shown in Figure B if a properly grounded outlet is not available.** The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. The green colored rigid ear or tab, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box.

* Canadian electrical codes require extension cords to be certified SJT type or better.
** Use of an adapter in Canada is not acceptable.

Maintenance

Use this section to record maintenance, service and any calls to Technical Support:

Maintenance

1. Apply a light coat of wax paste to the worktable to make feeding stock easier.
2. Use a vacuum cleaner and brush to clear out dust and debris from sander and motor.

Technical line drawing of a mechanical device with no visible text or symbols

Timing Drive Belt Replacement

1. Using a Phillips screwdriver, remove the screw (66) from belt cover (67), and remove cover.
2. Loosen three screws to allow drive pulleys (71 and 78) to move enough to place drive belt (70) around them.

Technical line drawings of mechanical components, showing hand operating a lever and wheel assembly (no text or symbols)

Maintenance

1. Place drive belt around drive pulley (71), then drive pulley (78).
2. Tighten the three screws slightly.
3. Adjust tension of drive belt by placing a standard screwdriver in the adjusting hole by pushing up on the screwdriver to apply tension to the drive belt.
4. Tighten the three screws again.
5. Squeeze the drive belt between two fingers in the centre of the belt. If the belt has been correctly tensioned there should be about 6mm (1/4") of "give".

NOTE: Too much tension on the drive belt can load-down motor and possibly cause damage. If the drive belt is too loose, it may fail prematurely.

1. Replace belt cover (67).
