CONNECTING SHAPER TO POWER SOURCE
GROUNDING INSTRUCTIONS
CAUTION: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR
FROM ELECTRIC SHOCK.
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. The motor is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in 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. If repair or replacement of the electric cord or plug is necessary, do not
connect the equipment grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded.
Repair or replace damaged or worn cord immediately.
SINGLE PHASE OPERATION
Fig. 41
Fig. 42
THREE HORSEPOWER
MOTORS
The motor supplied with single phase, 3 horsepower
Shapers is designed to be operated from a 220-240 volt
power system.
The single phase Shaper is intended to be used on
a circuit that has an electrical outlet that looks like the one
illustrated in Fig. 41. The tool has a plug similar to the plug
illustrated in Fig. 41. Make certain the tool is connected to
an outlet having the same configuration as the plug. No
adapter is available, or should be used with the tool.
CAUTION: IN ALL CASES, MAKE CERTAIN
THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A
CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.
The single phase, three horsepower Shaper motors are
single voltage motors and cannot be connected to
operate at a voltage other than 220-240 volts.
If you desire to operate the single phase 3 horsepower
Shaper with an extension cord, use a proper extension
cord and make certain it 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. Fig. 42, shows the
correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the cord.
