POWER CONNECTIONS

POWER CONNECTIONS

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine's plug. Before connecting the machine to the power line, make sure the switch(s) is in the "OFF" position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.

ADNIGER: OSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your machine is wired for 120/240 volts, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the "OFF" position.

GROUNDING INSTRUCTIONS

▲ DANGER: THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.

1. All grounded, cord-connected machines:

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 machine 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 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 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 machine is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine's plug, as shown in Figure A.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150 volts:

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure A, the machine will have a grounding plug that looks like the plug illustrated in Figure A. A temporary adapter, which looks like the adapter illustrated in Figure B, may be used to connect this plug to a matching 2-conductor receptacle as shown in Figure B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must be held in place with a metal screw.

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

A DANGERES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

3. 120 Volt Single-Phase Operation

The motor supplied with your machine is a dual voltage, 120/230 volt motor. It is shipped ready-to-run for 230 volt operation. However, it can be converted for 120 volt operation.

A qualified electrician should do the conversion, or the machine can be taken to an Authorized Delta Service Center. When completed, the machine must conform to the National Electric Code and all local codes and ordinances.

The machine is converted by re-wiring the motor for 120 volts, installing a 120 volt plug on the power supply cord and replacing the switch with one that is rated for 120 volt operation. Be sure the 120 volt plug is only used in an outlet having the same configuration as the plug illustrated in Figure A. or B. No adapter should be used with the 230 volt plug.

GROUNDED OUTLET BOX CURRENT CARRYING PRONGS GROUNDING BLADE IS LONGEST OF 3 BLADES

FIGURE C

EXTENSION CORDS

△CAUTION: Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine's plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Figure D shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

⚠ WARNING: In all cases, make certain that the receptacle in question is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

ADJUSTMENTS

TO ADJUST THE BELT TRACKING

WARNING:

Tools Needed: Belt Tracking Tool (provided)

Before making any adjustments to the tool, disconnect the machine from the power source.

1. Rotate the belt by hand from left to right and observe whether the belt is tracking above or below the edges of the rollers.
2. Using the belt tracking tool (provided) loosen the micro adjust lock nut.

3. Based on whether the belt is tracking up or down, turn the micro adjusting screw in 1/4 – turn increments to the left or right until the belt tracks evenly on the rollers when rotated by hand. See Figure 10.

4. Re-tighten the micro adjusting nut.

NOTE: The Belt Tracking Adjustment provides a minor adjustment that should correct most tracking problems. If the tracking problem persists, use the Motor Mount

Tracking

Adjustment (next section).

MOTOR MOUNT TRACKING ADJUSTMENT

Tools Needed: Two 1/2 inch Wrenches

Note: The Motor Mount Tracking Adjustment is a course adjustment. Use the Belt Tracking Adjustment first for fine adjustment. If it cannot be adjusted, then use the procedure described below.

WARNING:

Before making any adjustments to the machine from the power source.

1. Loosen the four motor mount nuts (A) just enough so the tracking screws can be turned to make an adjustment. See Figure 11.
2. Loosen the two locking hex nuts that secure the tracking screws.

3. Turn one screw a 1/4-turn and rotate the sanding belt by hand to observe which direction the adjustment is causing the belt to move. If it is traveling in the direction needed to correct the problem, go to step 5.

4. If the belt tracks in the wrong direction, back off a 1/4-turn and tighten the other screw a quarter turn. This should start the belt moving in the proper direction.

5. Tighten both locking nuts and motor mount nuts.

6. Return to the Belt Tracking Adjustment section (previous page) to fine tune the tracking.

MAINTENANCE PROCEDURES

Your Oscillating Edge Sander requires little maintenance beyond the routine inspection, lubrication, and cleaning.

ROUTINE INSPECTION

It is a good idea to routinely inspect any quality woodworking tool in order to keep it in optimum condition. This includes inspecting all hardware for tightness, ensuring drive belts are in good condition, and cleaning debris and grime from any surfaces and moving parts.

LUBRICATION

The sealed motor of your Oscillating Edge Sander is maintenance-free. However, it is recommended that you periodically lubricate the gears in the gear box using a quality #2 grease or equivalent. To keep the sander table and other bare metal parts in good working condition, apply an occasional coat of quality paste wax, free of silicone or synthetics.

CLEANING THE SANDING BELT

Regularly inspect and, if necessary, clean the sanding belt with a high quality gum rubber belt cleaner. If you notice sanding performance is significantly decreasing, it may be time to replace the sanding belt. Refer to directions on page 11.
