electrical panel provided there is a disconnect near
the machine for the operator. Consult electrical
drawings in sect. 15.0 for further clarification of
wiring setup.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the 3HP 1-phase, and 5HP
3-phase table saws be connected to a dedicated
20 amp circuit with breaker or fuse.
The 5HP 1-phase saw should be connected to a
30 amp circuit with breaker or fuse.
If connected to a circuit protected by fuse, use time
delay fuse marked "D". Local codes take
precedence over recommendations.

7.1 GROUNDING INSTRUCTIONS

This machine must be grounded. 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
equipment-grounding conductor. A plug is not
provided. A proper UL/CSA listed plug may be
installed or the machine may be "hard-wired" to a
circuit panel. If hard-wired, make sure a disconnect
is available to the operator.
Improper connection of the equipment-grounding
conductor can result in a 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.
replacement of the electric cord or a plug is
necessary, do not connect
grounding conductor to a live terminal.
Check
electrician or service
grounding instructions are not completely
understood, or if in doubt as to whether the
tool is properly grounded. Failure to comply
may cause serious or fatal injury.
Repair or replace damaged
immediately.
7.2 Voltage conversion (3-phase
model only)
1. Remove transformer cover at back of machine,
and move fuse from 230V position to 460V
position on transformer.
2. Switch the incoming power leads to the motor
for 460 volt operation, according to wiring
diagram on inside cover of motor junction box.
A similar diagram is found in sect. 15.0 of this
manual. (In case of discrepancy, diagram in
junction box takes precedence.)

3. Replace the 230V overload relay with a 460V
overload relay (additional purchase, part
number PM2000B-2107BORA).
4. If using a plug, the 230V plug must be
replaced with a UL/CSA listed plug rated for
460V.

7.3 Extension cords

USE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. When
using an extension cord, be sure to use one heavy
enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. Table 3
shows correct size to use depending on cord
length and nameplate ampere rating. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

7.4 Magnetic switch and safety key

Refer to Figure 7-2.
Power Indicator Light – The start switch has a
power indicator lamp which is on whenever there
is power connected to the saw, not just when the
saw is running. Do not assume that no light means
there is no power to the machine. If the bulb is bad,
there will no indication. Always check before use.
Do not rely that no light means
no power to the machine. Always check for
power first. Failure to comply may cause
serious injury.
Start – Press green start switch.
When power is connected to the machine, the
green light is always on regardless of whether the
saw is running or not.
Stop – Press red switch to stop.
Reset – If the saw stops without pressing the stop
button, as the result of a tripped fuse or circuit
breaker:
1. Press red button to reset.
2. Press green button to restart machine.
