EXTENSION CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
toot from overheating, use an extension cord that is
heavy enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 16 is recom-
mended for an extension cord 100 feet or less in
length. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
will be marked WA.
A
CAUTION: Keep extension cords away from the
sanding area and position the cord so that it wilt
not get caught on lumber, tools, etc., during
sanding.
_. WARNING: Check extension cords before each
n
use. If damaged replace immediately. Never use
tool with a damaged cord since touching the
damaged area could cause electrical shock
resulting in serious injury.
Extension cords suitable for use with your sander are
available at your nearest Sears Retail Store.
LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore,
no further lubrication is required.
