DeWalt DWE4557 instruction manual Cross Sectional Area Range Cord in meters mm, Not Recommended

•Avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel for cracks or flaws.

•Always handle and store wheels in a careful manner.

•Never cut into area that may contain electrical wiring or piping. Serious injury may result.

•Do not operate this tool for long periods of time. Vibration caused by the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.

•Direct the Dust Ejection System (DES) away from operator and coworkers. Serious injury may result.

•When gear case grip is properly installed the use of the side handle is not required.

•Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts.

•An extension cord must have adequate wire size for safety. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Voltage (Volts)	Total length of cord in meters (m)
120–127V	0–7	7–15	15–30	30–50
220–240V	0–15	15–30	30–60	60–100
Rated Ampere	Minimal	cross-	sectional	area of the

6–10A	1.0	1.5	2.5	4.0
10–12A	1.5	1.5	2.5	4.0
12–16A	2.5	4.0	Not Recommended

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 paints,

•crystalline silica from bricks and cement and other masonry products, and

•arsenic and chromium from chemically-treated lumber (CCA). 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 specially designed to filter out microscopic particles.

•Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.

WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. All users and bystanders MUST ALWAYS wear certified safety equipment:

•ANSI Z87.1 eye protection (CAN/CSA Z94.3),

•ANSI S12.6 (S3.19) hearing protection,

•NIOSH/OSHA/MSHA respiratory protection.

WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.
