Grounded tools require a three wire extension cord. Double
insulated tools can use either a two or three wire extension
cord. As the distance from the supply outlet increases, you
must use a heavier gauge extension cord. Using extension
cords with inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the greater the
capacity of the cord. For example, a 14 gauge cord can
carry a higher current than a 16 gauge cord. When using
more than one extension cord to make up the total length,
be sure each cord contains at least the minimum wire size
required. If you are using one extension cord for more than
one tool, add the nameplate amperes and use the sum to
determine the required minimum wire size.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE.
W ARNING
To reduce the risk of injury, always unplug
tool before attaching or removing
accessories or making adjustments. Use
only specifically recommended
accessories. Others may be hazardous.
Collets
The collet must be attached to the collet nut
before it is put into the collet shaft. Be sure that
the size of the collet matches the size of the bit
shank being used. If the wrong size bit shank is
used, the collet may break. For attaching or
detaching the collet nut to the collet, follow the
illustrated instructions on this page.
EXTENSION CORDS
Guidelines for Using Extension Cords
•
If you are using an extension cord outdoors, be sure it is
marked with the suffix "W-A" ("W" in Canada) to indicate
that it is acceptable for outdoor use.
•
Be sure your extension cord is properly wired and in
good electrical condition. Always replace a damaged
extension cord or have it repaired by a qualified person
before using it.
•
Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

TOOL ASSEMBLY
Attaching Collet to Collet Nut
To assemble, place the narrow end of the collet on an
even surface. Take the nut and place it over the collet
(Fig. 1).
Position nut squarely over collet with the smaller
opening of the nut facing up (Fig. 2).
