230 Volt Operation
As received from the factory, the DT65
Dovetailer is designed to run on 230 volt power
only. You may either connect a UL/CSA listed
230V plug (similiar to the one shown in Figure 6)
or “hard-wire” the machine directly to a control
panel. If hard-wired to a panel, make sure a
disconnect is available for the operator. The
dovetailer must comply with all local and
national codes after being wired.
1. If it is to be hard-wired, make sure the fuses
have been removed or the breakers have
been tripped in the circuit to which the
dovetailer will be connected. Place a
warning placard on the fuse holder or circuit
breaker to prevent it being turned on while
the machine is being wired.
2. Refer to “Electrical Connections” on page 36
for connecting the motor leads.
3. The Dovetailer with a 230 volt plug should
only be connected to an outlet having the
same configuration. No adapter is available
or should be used with the 230 volt plug.
Extension cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine’s motor plate. An undersized cord
will cause a drop in line voltage resulting in loss
of power and overheating.
Use the chart in Figure 7 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Air Connection
Connect the air supply hose to the coupling on
the air unit (Figure 8). The air is turned ON by
rotating the valve lever 90 degrees
counterclockwise (until it is parallel with the
hose), and turned OFF by rotating the valve
lever 90 degrees clockwise.
Even after the air has been
turned off to the machine, there may be
residual air inside the lines, and the
clamping cylinders can still provide a hazard
to fingers. After shutting off the air, always
bleed residual air from the system by
pushing the relief valve pin at the bottom of
the air cup, shown in Figure 8. Keep the
relief valve open until all air in the system
has been removed.
