ELEGTRJCAL REQUiREMENTS AND SAF
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR
BREAKDOWN, grounding provides a path of least
resistance for electric currents and reduces the risk of
electric shock. This tool is equipped with an electrical
cord that has an equipment-grounding conductor
and a grounding plug. The plug must be plugged
into a matching receptacle 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 receptacle, have the proper receptacle installed
by a qualified electrician.
IMPROPER CONNECTION of the equipment grounding
conductor can result in risk of electric shock. The
conductor with the green insulation (with or without
yellow stripes) is the equipment grounding conductor.
If repair or replacement of the electrical cord or plug is
necessary, do not connect the equipment grounding
conductor to a live terminal.
or a #14 wire with a 15 A time-lag fuse. NOTE: When
using an extension cord on a circuit with a #14 wire, the
extension cord must not exceed 25 feet in length. Before
connecting the motor to the power line, make sure the
switch is in the off position and the electric current is
rated the same as the current stamped on the motor
nameplate. Running at a lower voltage will damage the
motor. This tool is Intended for use on a circuit that has
a receptacle like the one illustrated in Fig. 1.
Fig. 1 shows a three-pronged electrical plug and
receptacle that has a grounding conductor. If a properly
grounded receptacle is not available, an adapter (Fig. 2)
can be used to temporarily connect this plug to a two-
contact grounded receptacle. The adapter (Fig. 2) has a
rigid lug extending from it that MUST be connected to a
permanent earth ground, such as a properly grounded
receptacle box.
CAUTION
In all cases, make certain the receptacle is properly
grounded. If you are not sure, have a qualified
electrician check the receptacle.
CHECK with a qualified electrician or service person
if you do not completely understand the grounding
instructions, or if you are not certain the tool is properly
grounded.
USE only three-wire extension cords that have three­
pronged grounding plugs with three-pole receptacles
that accept the tool’s plug. Repair or replace damaged
or worn cords immediately.
GUIDELINES FOR EXTENSION CORDS
USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. Use an
extension cord 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,
overheating and burning out of the motor. The table on
the right shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Make sure your extension cord is properly wired and in
good condition. Always replace a damaged extension
cord or have it repaired by a qualified technician before
using it. Protect your extension cords from sharp
objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tool. This circuit
must not be less than #12 wire with a 20 A time-lag fuse
CAUTION
This tool is for indoor use only. Do not expose to
rain or use in damp locations.
CAUTION
This tool must be grounded while in use to protect
the operator from electric shock.
