forces. Kickback forces can be controlled by the operator, if proper precautions are taken.

•When wheel is binding, or when interrupting a cut for any reason, release the trigger and hold the unit motionless in the material until the wheel comes to a complete stop. Never attempt to remove the unit from the work or pull the unit backward while the wheel is in motion or kickback may occur. Investigate and take corrective actions to elimi- nate the cause of wheel binding.

•When restarting a cut-off tool in the workpiece, check that the wheel is not engaged into the material. If wheel is binding, it may walk up or kickback from the workpiece as the tool is restarted.

•Support large panels to minimize the risk of wheel pinch- ing and kickback. Large panels tend to sag under their own weight. Support must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chem- icals 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 equip- ment, 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 appropri- ate for the dust exposure. Direct particles away from face and body.

CAUTION: Use extra care when working into a corner because a sudden, sharp movement of the grinder may be experienced when the wheel or other accessory contacts a secondary surface or a surface edge.

CAUTION: Wear appropriate personal hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

FEATURES

E-SWITCH PROTECTION™

The ON/OFF switch has a no-volt release function. In the event of a power outage or other unexpected shut down, the switch needs to be cycled (turned off and on) to restart tool.

CLUTCH (D28140, D28144, D28144N)

The torque limiting clutch reduces the maximum reaction torque transmitted to the operator in case of jamming a cutting disc. This feature also prevents the gearing and electric motor from stalling. The torque limiting clutch has been factory set and cannot be adjusted.

E-CLUTCH™

This unit is equipped with an E-Clutch™ (Electronic Clutch), which in the event of a high-load or wheel pinch, the unit will shut off to reduce the reaction torque to the user. The switch needs to be cycled (turned off and on) to restart the tool.

POWER-OFF™ OVERLOAD PROTECTION

The power supply to the motor will be reduced in case of motor overload. With continued motor overload, the tool will shut off. The
