POWER SOURCE
Do not connect to the power source until the machine is
completely assembed.
The motor is designed for operation on the voltage and
frequency specified. Normal loads will be handled safely
on voltages not more than 10% above or below specified
voltage. Running the unit on voltages which are not within
range may cause overheating and motor burnout. Heavy
loads require that voltage at motor terminals be no less
than the voltage specified on nameplate.
• Power supply to the motor is controlled by a switch with
key. Removing the key from switch will lock the unit and
prevent unauthorized use.
GROUNDING INSTRUCTIONS
Improper connection of equipment grounding conductor
can result in the risk of electrical shock. Equipment should
be grounded while in use to protect operator from electri-
cal shock.
• Check with a qualified electrician if you do not
understand grounding instructions or if you are in
doubt as to whether the tool is properly grounded.
• This tool is equipped with an approved cord rated at
120V and a 3-prong grounding type plug (see Figure
5) for your protection against shock hazards.
• Grounding plug must be plugged directly into a
properly installed and grounded 3-prong grounding type
receptacle, as shown (see Figure 5).
• Do not remove or alter grounding prong in any manner.
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electrical shock.
Do not permit fingers to touch the terminals of plug when
installing or removing from outlet.
• Plug must be plugged into matching outlet that is
properly installed and grounded in accordance with all
local codes and ordinances. Do not modify plug
provided. If it will not fit in outlet, have proper outlet
installed by a qualified electrician.
• Inspect tool cords periodically, and if damaged, have
repaired by an authorized service facility.
• Green (or green and yellow) conductor in cord is the
grounding wire. If repair or replacement of the electric
cord or plug is necessary, do not connect the green (or
green and yellow) wire to a live terminal.
• A 2-prong wall receptacle must be replaced with a
properly grounded 3-prong receptacle installed in
accordance with National Electric Code and local codes
and ordinances.
EXTENSION CORDS
• The use of any extension cord will cause some drop in
voltage and loss of power.
• Wires of the extension cord must be of sufficient size to
carry the current and maintain adequate voltage.
• The minimum extension cord wire size is A.W.G. 14.
Do not use extension cords over 25 feet long.
• Use only 3-wire extension cords having 3-prong
grounding type plugs and 3-pole receptacles which
accept the tool plug.
• If the extension cord is worn, cut or damaged in any
way, replace it immediately.

ELECTRICAL CONNECTIONS
Make sure unit is turned off and disconnected from power
source before inspecting any wiring.
The motor is installed and wiring connected as illustrated
in the wiring schematic (see Figure 6).
Figure 6 Wiring Schematic
The motor is assembled with an approved three conductor
cord to be used on 120 volts as indicated. The power
supply to the motor is controlled by a double pole locking
switch.
The power lines are connected directly to the switch.
The green ground line must remain securely fastened
to the frame to properly protect against electrical shock.
A manual reset overload protector is installed in line with
the power supply to the motor. If the motor is overloaded,
the protector will break the circuit.
