EXTENSION CORDS

Use proper extension cords. Make sure
your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type
plug and matching receptacle which will accept the
machine’s plug. When using an extension cord, be sure
to use one heavy enough to carry the current of the
machine. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. Fig.
D shows the correct gauge to use depending on the
cord length. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

200-220 VOLT, THREE PHASE

OPERATION

If the motor on your machine is wired for 200-220 Volt,
Three Phase operation, proceed as follows when con-
necting your planer to an electrical power system:
1. Remove the two screws that attach the switch
cover (A) Fig. B, to the switch box and remove the
switch cover (A).
2. Remove lower right knockout from bottom of
switch box (B) Fig. C, and assemble a strain relief
(not supplied) in its place.
3. Bring the three phase power line up through the
strain relief, and connect the three power lines to
terminals L1, L2 and L3, shown at (C) Fig. C, and
connect the green ground wire to ground screw (D).
4. IMPORTANT: IF AFTER THE MACHINE IS IN
OPERATION THE CUTTERHEAD REVOLVES IN
THE WRONG ROTATION, INTERCHANGE ANY
TWO OF THE THREE POWER LINES THAT ARE
CONNECTED TO TERMINALS (C) FIG. C.
5. Replace switch cover that was removed in STEP 1.

THREE PHASE OPERATION

Three phase MACHINES are not supplied with a power
cord. They must be permanently connected to the
building electrical system and grounded according to
the National Electrical Code. Since they must be
permanently connected to the building electrical
system, extension cords cannot be used with three
phase MACHINES.
