POWER CONNECTIONS
Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as
to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching, properly grounded 3-conductor receptacles
that accept the machine’s plug, as shown in Figure A, or a properly grounded receptacle with a grounding means adapter, as shown
in Figure B.
Repair or replace damaged or worn cord immediately.
IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU
ARE NOT SURE, HAVE A qualied ELECTRICIAN CHECK THE RECEPTACLE.
This is a grounded, cord-connected tool intended for use on a supply circuit having a nominal voltage of 120 volts. It is intended to
for use on a circuit that has an outlet as shown in FIG. A. It has a plug as shown in FIG A. If you have a 2 pole receptacle as shown
in FIG. B you may use a temporary adapter, as shown in FIG. B. if a properly grounded outlet is not available. The green ear lug
extending from the adapter must be connected to a permanent grounded outlet box. The temporary adapter should be used only
until a properly grounded outlet can be installed by a qualified electrician.
EXTENSION CORDS
Never use a damaged extension cord. Check extension cords before each use. If damaged, replace immediately.
Touching the damaged area could case electrical shock resulting in serious injury.
Keep the extension cord clear of the work area. Position the cord so it will not get caught on lumber, tools or other
obstructions.
• Use proper extension cords. Make sure your extension cord is a 3-wire extension cord which has a 3-prong grounding type plug
and matching receptacle which will accept the machine’s plug, as described in this manual’s Grounding Instructions. When using
an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop
in line voltage, resulting in loss of power and overheating. The table below shows the maximum gauge to use depending on the
cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Only round, jacketed
cords listed by Underwriter’s Laboratories (UL) should be used.
