POWER REQUIREMENTS
The tool is equipped with a three-prong plug and must be plugged into a grounded, single-phase
electrical receptacle (Figure A below). If an adapter is used to accommodate the three-prong plug,
the adapter’s wire must be attached to a known ground (refer to Figures A and B and power supply
chart below). Never remove the third prong.
EXTENSION CORD REQUIREMENTS
FOR ELECTRICALLY-POWERED TOOLS
It is important to use the proper extension cord size (e.g. conductor-sized American Wire Gauge/cir-
cular mils) when pre-wired outlets are not available. Cord size selection is based upon tool rating
(volts/amps) and cord length (feet/meters). Use of cord size thinner than required will cause a signif-
icant voltage drop at the tool while it is operating. The voltage drop may cause damage to the tool
and can result in failure of the tool to operate properly. Use of a heavier cord size than required is
acceptable.
The chart below contains the required cord sizes for cord lengths up to and including 100 feet (30
meters). Avoid using cords beyond 100 feet (30 meters) in length.
• To reduce the risk of electric shock, make sure the electrical source is properly grounded, and
follow all instructions carefully.
• Before performing any maintenance on the tool, disconnect it from the electrical source.
• Always unplug tool after each use.
Failure to follow these instructions could result in death or serious personal injury.
NOTICE
• The tool is equipped with a UL Listed three-conductor cord and three-prong grounding type plug to fit the proper,
grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never
connect the green (or green and yellow) wire to a live terminal.
