GROUNDING INSTRUCTIONS

WARNING: Improper connection of equipment grounding
conductor can result in the risk of electrical shock. Equipment
must 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.
• This tool is equipped with an approved 3-conductor cord
rated at 150V and a 3-prong grounding type plug
(Figure 7) for your protection against shock hazards.
• Grounding plug should be plugged directly into a properly
installed and grounded 3-prong grounding-type receptacle,
as shown (Figure 7).

WARNING: 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 a qualified 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.
• Where a 2-prong wall receptacle is encountered, it must
be replaced with a properly grounded 3-prong receptacle
installed in accordance with National Electric Code and
local codes and ordinances.
WARNING: This work should be performed by a qualified
electrician.
A temporary 3-prong to 2-prong grounding adapter (see
Figure 8) is available for connecting plugs to a two pole outlet
if it is properly grounded.

• Do not use a 3-prong to 2-prong grounding adapter unless
permitted by local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted in
Canada.) Where permitted, the rigid green tab or terminal on
the side of the adapter must be securely connected to a
permanent electrical ground such as a properly grounded
water pipe, a properly grounded outlet box or a properly
grounded wire system.
• Many cover plate screws, water pipes and outlet boxes
are not properly grounded. To ensure proper ground,
grounding means must be tested by a qualified electrician.
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.
• Use the table below to determine the minimum wire size
(A.W.G.) extension cord.
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

WARNING: All electrical connections must be performed by
a qualified electrician. Make sure tool is off and disconnected
from power source while motor is mounted, connected,
reconnected or anytime wiring is inspected.
Motor and wires are installed as shown in wiring schematic
(See Figure 9). Motor is assembled with approved,

green ground line must remain securely fastened to the frame
receptacle
to properly protect against electrical shock. The power supply
to the motor is controlled by a single pole locking rocker
switch.
