ELECTRICAL CONNECTIONS
Both a manual circuit breaker (or similar device) as well
as an electrical plug are recommended and should
be installed by a qualified electrician. Use locally ap-
proved wire that includes a separate grounding wire
and a 3 prong grounding type plug
A with a matching
receptacle B .
GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit,
grounding reduces the risk of electric shock to the ope-
rator. The motor of this machine is wired for 220V single
phase operation. As with many stationary industrial
type machines, because each installation situation is
unique, this table saw is supplied without a power cord
or plug. The installation of an appropriate power cord
and plug must be performed by a qualified electrician.
The machine must be connected to an electrical
source using a power cord that has a grounding wire,
which must also be properly connected to the ground-
ing prong on the plug. The outlet must be properly
installed and grounded and all electrical connections
must be made in accordance with all local codes and
regulations.
BEFORE CONNECTING THE MACHINE TO THE POWER SOURCE, VERIFY THAT THE VOLTAGE OF YOUR POWER SUPPLY CORRESPONDS
WITH THE VOLTAGE SPECIFIED ON THE MOTOR I.D. NAMEPLATE. A POWER SOURCE WITH GREATER VOLTAGE THAN NEEDED CAN
RESULT IN SERIOUS INJURY TO THE USER AS WELL AS DAMAGE TO THE MACHINE. IF IN DOUBT, CONTACT A QUALIFIED ELECTRICIAN
BEFORE CONNECTING TO THE POWER SOURCE.
THIS TOOL IS FOR INDOOR USE ONLY. DO NOT EXPOSE TO RAIN OR USE IN WET OR DAMP LOCATIONS.
CIRCUIT CAPACITY
Make sure that the wires in your circuit are capable of
handling the amperage draw from your machine, as
well as any other machines that could be operating on
the same circuit. If you are unsure, consult a qualified
electrician. If the circuit breaker trips or the fuse blows
regularly, your machine may be operating on a circuit
that is close to its amperage draw capacity. However, if
an unusual amperage draw does not exist and a
power failure still occurs, contact a qualified technician
or our service department.
EXTENSION CORDS
The use of an extension cord is not generally recom-
mended for 220V equipment. If you find it necessary,
use only 3-wire extension cords that have 3-prong
grounding plug and a matching 3-pole receptacle that
accepts the tool’s plug. Repair or replace a damaged
extension cord or plug immediately.
If you find it necessary to use an extension cord with
your machine make sure the cord rating is suitable for
the amperage listed on the motor I.D. plate. An under-
sized cord will cause a drop in line voltage resulting in
loss of power and overheating. The accompanying
chart shows the correct size extension cord to be used
based on cord length and motor I.D. plate amp rating.
If in doubt, use the next heavier gauge. The smaller the
number, the heavier the gauge.

NOTE: VOLTAGE REQUIREMENTS AND AMPERAGE DRAW FOR 5HP M2 & M3 3-PHASE MOTORS MAY NOT BE FULLY DES-
CRIBED IN THIS MANUAL. FOR COMPLETE ELECTRICAL REQUIREMENTS REFER TO THE MOTOR I.D. NAME PLATE ON
THE MACHINE. IF IN DOUBT CONSULT A LICENSED QUALIFIED ELECTRICIAN BEFORE PROCEEDING.
