GROUNDING INSTRUCTIONS
WARNING: Improper oonnsction of equipment grounding
conductor can result in the risk of electrical shock. Equipment
should be groundedwhile 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 8)
for your protection against shock hazards.
• Grounding plug should be plugged directly into a properiy
installed and grounded 3-prong grounding-type recaptacle,
as shown (Figure 8).

3-Prong Plug
Figure 8 - 3-Prong Receptacle
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 instaUing 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,
• Where a 2-prong wall receptacle is encountered, it must be
replaced with a properly grounded 3-prong receptacle
installed in accordance with National Electdc 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 9) is available for connecting plugs to a two pole outlet
If It is propedy grounded.

Do net use a 3-prong to 2-prong grounding adapter unless

(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 propedy
grounded wire system,
• Many cover plate screws, water pipes and outlet boxes are
not propedy grounded. To ensure proper ground, grounding
• means must be tested by a qualified electrician.
EXTENSION CORDS
• The use of any extension cord will cause ,somedrop 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 to determine the minimum wire size (A.W.G.)
extension cord.
• Use only 3-wire extansion cords having 3-prong grounc_ng
type plugs and 3-pole receptacles which acoapt the tool
plug.
• If the extension cord is worn, cut, or damaged in any way,
replace it immediately.

ELECTRICAL CONNECTIONS
WARNING: An electrical connections must be performed by
a qualified electrician. Make sure tool is oft and disconnected
from power source while motor is mounted, connected, recon-
nected or anytime wiring is inspected.
Motor and wires are instafied as shown in wiring schematic
(See Figure 10). Motor is assembled with approved,
3-conductor cord to be used at 120 volts.

Figure 10 -Wiring Schamati_
The power lines are inserled directly onto the switch. The
green ground line must remain securely fastened to the frame
to properly protect against electdcal shook. The power supply
to the motor is controlled by a single pole locking rocker switch.
• Remove the key to prevent unauthorized use.
