Extension cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
contain a ground wire, match the required plug
and receptacle, and meet the following require-
ments:
Minimum Gauge Size at 110v ..............12 AWG
Minimum Gauge Size at 220v .............14 AWG
Maximum Length (Shorter is Better).......50 ft.
voltage conversion
the voltage conversion MUSt be performed by
a qualified electrician. to perform the voltage
conversion, replace the power cord, install the
correct plug, and rewire the motor to the new volt-
age, according to the provided wiring diagram on
page 52.
Note: If the diagram included on the motor con-
flicts with the one in this manual, the motor may
have changed since the manual was printed. Use
the diagram provided inside the motor wiring junc-
tion box.
To convert the machine to 110v:
1. diSConneCt MAChine FroM poWer!
2. replace the power cord with one that match-
es the cord specifications under circuit
Recommendations for 110v on page 9.
3. replace the 6-15 plug on the power cord with
a neMA 5-20 plug.
4. re-wire the motor as illustrated in the wiring
diagram.
Disabling & Locking
Switch
figure 4. Switch disabled by a padlock.
The ON/OFF switch can be disabled and locked
by inserting a padlock through the ON button,
as shown. Locking the switch in this manner can
prevent unauthorized operation of the machine,
which is especially important if the machine is not
stored inside an access-restricted building.
IMPORTANT: Locking the switch with a padlock
only restricts its function. It is not a substitute
for disconnecting power from the machine when
adjusting or servicing.
Shaft
Padlock
0.12"–0.15"
NOTICE
The padlock shaft diameter is important to
the disabling function of the switch. With
any padlock used to lock the switch, test
the switch after installation to ensure that it
is properly disabled.
children or untrained people can be
seriously injured by this machine. This
risk increases with unsupervised operation.
To help prevent unsupervised operation,
disable and lock the switch before leaving
machine unattended! place key in a well-
hidden or secure location.
