EXTENSION CORDS
If you find it necessary to use an extension cord
with your machine, use only 3-wire extension
cords that have 3-prong grounding plug and a
matching 3-pole receptacle that accepts the
tool’s plug. Repair or replace a damaged ext-
ension cord or plug immediately. Make sure
the cord rating is suitable for the amperage
listed on the motorI.D. plate. An undersized
cord will cause a drop in line voltage resulting
in loss of power and overheating.The accom-
panying chart shows the correct size extension
cord to be used based on cord length and motor
I.D. plate amp rating.
