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.
DO NOT EXPOSE 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
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 Fig. 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 Fig. A, the
machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like
the adapter illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor receptacle as shown
in Fig. 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.
IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.
IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

3. 240 Volt Single-Phase Operation
The motor supplied with your machine is a dual voltage, 120/240 volt motor. It is shipped ready-to-run for 120 volt
operation. However, it can be converted for 240 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 240 volts, installing a 240 volt plug on the power supply cord and
replacing the switch with one that is rated for 240 volt operation. Be sure the 240 volt plug is only used in an outlet
having the same configuration as the plug illustrated in Fig. C. No adapter should be used with the 240 volt plug.
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.
MINIMUM GAUGE EXTENSION CORD
RECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC MACHINES
FIG. C
EXTENSION CORDS
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. Fig. 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.

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.
