Delta 23-730 Grinder User Manual

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 a 3-pole
receptacle which will accept the tool’s plug. When using
an extension cord, be sure to use one heavy enough to
carry the current of the saw. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. Fig. 14, 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.

CONNECTING TOOL TO POWER SOURCE
POWER CONNECTIONS
A separate electrical circuit should be used for your tools. 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 3-pole receptacles which accept the tool’s plug. Before connecting the motor to the
power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same
characteristics as indicated on the tool. All line connections should make good contact. Running on low voltage will
damage the motor.
MOTOR SPECIFICATIONS
Your tool is wired for 120 volt, 60 HZ alternating current. Before connecting the tool to the power source, make sure
the switch is in the “OFF” position. The motor for the 23-725 & 23-735 provides a no-load speed of 1725 RPM. The
motor for the 23-730 provides a no-load speed of 3450 RPM.
GROUNDING INSTRUCTIONS
WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
1. All grounded, cord-connected tools: 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 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 3-wire extension cords that have 3-prong grounding type plugs and 3-pole receptacles that accept the tool’s
plug, as shown in Fig. 15.
Repair or replace damaged or worn cord immediately.
