WIRE MOTOR TO CONTACTOR
• See wiring schematic supplied with motor and wire motor
for 230 volt operation, clockwise rotation as viewed from
shaft end of motor.
• Wire motor to motor cord which is connected to terminals
2 and 6 on the contactor thermal overload.
• Be sure to use strain relief supplied to secure motor cord
in motor junction box knock-out. Be sure green ground
wire on motor cord is properly grounded to motor inside
junction box. Use wire nuts and electrical tape to connect
and insulate wires.
NOTE: Motor must run in a clockwise rotation. (Viewing top of
blade, teeth must rotate from rear to front of saw.) If saw does
not rotate in proper direction, wiring and all connections must
be checked and corrected.
WARNING: Once rotation is checked, disconnect power
before working with motor or tool.
WIRE MAGNETIC STARTER TO SOURCE
Refer to Figure 6.
The saw should be connected to power source with perma-
nent wiring (hard wired). Power leads are to be supplied and
connected by a qualified electrician.
IMPORTANT: Motor and magnetic starter must be properly
grounded. Wiring should be performed by a qualified electri-
cian according to all local codes and ordinances.
• Be certain power leads are sufficient in size to adequately
carry the saw's voltage and amp load.
• Ground the magnetic starter. Connect the ground lead to
magnetic starter's ground screw. The ground lead will be
green or green with yellow stripe. Fasten securely.
• Power leads are connected to magnetic starter terminals
L1 and L3.
WARNING: Do not connect power leads to any other
terminal or fastener.
• Wire power supply cord into junction box (Figure 11, Ref.
No. 37) on rear of cabinet.
• When wiring the saw to the source, install a fused safety
disconnect switch between the saw and the circuit break-
er. Be certain the safety disconnect switch is capable of
being locked in the OFF position. The safety disconnect
switch is a safety precaution which allows the operator to
lock the saw OFF so it is unable to receive power. This
feature is intended to prevent accidental start-up when
maintaining or servicing saw. In addition, it is intended to
prevent unauthorized and possible hazardous use by oth-
ers. A key lock switch is provided on the tool for the same
reasons.
• The safety disconnect switch is fused. Protect the saw with
a 20 amp time-delay fuse or 20 amp manual reset circuit
breaker. Do not use fuses or breakers with a greater
amperage rating.
• Wire the saw to a breaker box or fuse box with adequate
capacity wire to accommodate the stationary saw's volt-
age and amp load.
IMPORTANT: Be certain saw is wired to a circuit protected by
a 20 amp breaker or fuse.
• Wire the saw to a breaker box or fuse box with adequate
capacity wire to accommodate the stationary saw's volt-
age and amp load.
SET THERMAL OVERLOAD
Refer to Figure 6.
Terminal L2 is not used. Magnetic starter is protected with a
thermal overload (lower right-hand corner). Be certain over-
load is positioned at manual (hand) reset. Position heater
(overload) adjustment at saw, 16 Amps, replace cover and
secure all line cords.

GROUNDING INSTRUCTIONS
WARNING: Improper connection of equipment grounding con-
ductor can result in the risk of electrical shock. Equipment should
be grounded while in use to protect operator from electrical shock.
• Check with a qualified electrician if grounding instructions
are not understood or if in doubt as to whether the tool is
properly grounded.
• Do not remove or alter grounding prong in any manner. In
the event of a malfunction or breakdown, grounding pro-
vides a path of least resistance for electrical shock.
WARNING: Do not permit fingers to touch the terminals of
plug when installing or removing from outlet.
