Milwaukee Tool 5363-21 User Manual

SPECIFIC SAFETY RULES

• Wear ear protectors. Exposure to noise can

cause hearing loss.

• Use auxiliary handle(s), if supplied with the

tool. Loss of control can cause personal injury.

• Hold power tools by insulated gripping surfaces,

when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Cutting accessory contacting a live wire may make
exposed metal parts of the power tool live and could
give the operator an electric shock.

• Keep hands away from all cutting edges and

moving parts.

• Maintain labels and nameplates. These carry

important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.

• WARNING: Some dust created by power sanding,

sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:

• lead from lead-based paint
• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-treated

lumber.

Your risk from these exposures varies, depending

on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are spe-
cially designed to fi lter out microscopic particles.

GROUNDING

WARNING

Improperly connecting the

grounding wire can result in the risk of

electric shock. Check with a qualifi ed electri-
cian if you are in doubt as to whether the
outlet is properly grounded. Do not modify
the plug provided with the tool. Never remove
the grounding prong from the plug. Do not
use the tool if the cord or plug is damaged. If
damaged, have it repaired by a MILWAUKEE
service facility before use. If the plug will not
fi t the outlet, have a proper outlet installed by
a qualifi ed electrician.

Grounded Tools: Tools with Three Prong Plugs
Tools marked “Grounding Required” have a three
wire cord and three prong grounding plug. The
plug must be connected to a properly grounded
outlet (See Figure A). If the tool should electrically
malfunction or break down, grounding provides a
low resistance path to carry electricity away from
the user, reducing the risk of electric shock.
The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire in the
cord must be the only wire connected to the tool's
grounding system and must never be attached to
an electrically “live” terminal.
Your tool must be plugged into an ap-
propriate outlet, properly installed and
grounded in accordance with all codes
and ordinances. The plug and outlet
should look like those in Figure A.
Double Insulated Tools: Tools with Two Prong
Plugs
Tools marked “Double Insulated” do not require
grounding. They have a special double insula-
tion system which satisfi es OSHA requirements
and complies with the applicable standards of
Underwriters Laboratories, Inc., the
Canadian Standard Association and
the National Electrical Code. Double
Insulated tools may be used in either
of the 120 volt outlets shown in
Figures B and C.

FUNCTIONAL DESCRIPTION

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.

Guidelines for Using Extension Cords
• If you are using an extension cord outdoors,

be sure it is marked with the suffi x “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 qualifi ed person before using it.

• Protect your extension cords from sharp objects,

excessive heat and damp or wet areas.
