GROUNDING

WARNING Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified 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 fit the outlet, have a proper outlet installed by

a qualified 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 appropri- ate outlet, properly installed and grounded in

accordance with all codes and ordi-

nances. The plug and outlet should

EXTENSION CORDS

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 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.

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 satisfies 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 ei-
ther of the 120 volt outlets shown in	Fig. B Fig. C
Figures B and C.

ASSEMBLY

WARNING To reduce the risk of injury, always unplug tool before attaching or removing accessories or making adjust-

ments. Use only specifically recommended accessories. Others may be hazardous.

Raising and Lowering the Head

The head must be locked down for transporting and storing the tool.

To unlock, press head down and pull out the lock down pin.

To lock, press head down and push in the lock down pin.

WARNING To reduce the risk of injury, use only the proper wheel for this ma- chine. DO NOT USEANYTYPE OF SAW BLADE.

Removing and Installing Cut-Off Wheels

Use only MILWAUKEE 14" Abrasive Cut-Off Wheels, 3/32” thick with this tool. Before operating the tool, make sure the wheel is in good condition as described in the “Specific Safety Rules”.

To change wheels:

1.Unplug the tool.

2.Raise the head.
