GENERAL POWER TOOL SAFETY WARNINGS

WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SPECIFIC SAFETY RULES

•Always use safety strap when drilling overhead or on a vertical surface (see “Safety Strap” under “Operation”). Mounting can release.

•Clean the surface before attaching the drill stand to the work surface. Paint, rust, scale, or uneven surfaces decrease the holding strength of the magnet. Chips, burrs, dirt and other foreign matter on the surface of the magnet base will also decrease holding power.

•Do not attach magnetic base to nonmagnetic grades of stainless steel. The magnetic base WILL NOT hold. The electromagnetic drill press attaches magnetically to 3/8" or thicker ferrous stock. Do not use on stock less than 3/8".

•Wet connections are shock hazards. If the plug or connections get wet, turn power off to the outlet before unplugging the tool. Prevent cutting fluid from traveling along the cord and contacting the outlet, extension cord connections or tool plug. Each time tool is plugged in, elevate extension cord or gang box connections and arrange a drip loop.

•Maintain labels and nameplates. These carry im- portant 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 can- cer, 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- cifically designed to filter out microscopic particles.

•Safety Strap

A.Do not use near acids or bleaching agents. B.Do not use for overhead lifting.

C.Do not use strap if webbing is cut. D.Webbing must be protected from sharp edges. E.All hardware must be in line with direction of pull for rated capacity.

DANGER! To reduce the risk of injury, always keep hands, rags, clothing, etc. away from moving parts and chips. Do not try to remove chips while the cutter is rotating. Chips are sharp and can pull objects into moving parts.

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 Cana-

da) 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.
