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-hole
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 tool. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. Figs. 27 & 27A, 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.

240 VOLT,
SINGLE PHASE OPERATION
The motor supplied with your tool is a dual voltage 120/240
volt motor. If it is desired to operate your dust collector at
240 volts, single phase, contact your local Authorized
Delta Service Center or qualified electrician for proper
procedures to rewire your dust collector motor for 240 volt
operation and wiring a 240 volt attachment plug to the
power supply cord.
The tool with a 240 volt plug should only be connected to
an outlet having the same configuration as the plug
illustrated in Fig. 26. No adapter is available or should be
used with the 240 volt plug.
AS A PRECAUTION IN ALL CASES, MAKE CERTAIN
THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
