7.2 Voltage conversion

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 PM3000B-2107AOR).
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.
7.4.1 Safety Key
The switch is equipped with a magnetic safety key.
When in place on the switch as shown in Figure 7-
2, the safety key trips a relay which will allow the
machine to start and stop when the respective
switches are pressed. Being magnetic, the key can
be removed to make the machine inoperable and
can be hidden for safe storage by attaching it
underneath the rail or another magnetic surface.
When using the saw, place the key on the switch
cover lining up the arrow on the key with the
REMOVE arrow on the cover. Then rotate the key
so the arrow lines up with the LOCK arrow. This
prevents the safety key from vibrating loose when
machine is in use.
