Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be
suitable for one tool may create a risk of injury when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury.
Safety Rules for Cordless Hammer Drills
Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring.
Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.
Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss.
Always use auxiliary handle for maximum control over torque reaction or
High torque 3/8" and larger chuck capacity drills are equipped with auxiliary handles.
Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.
Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by
Secure the material being drilled. Never hold it in your hand or across legs.
Unstable support can cause the drill bit to bind causing loss of control and injury.
Disconnect battery pack from tool or place the switch in the locked or off position before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or jammed in the work, the reaction torque of the tool could crush your hand or leg.
If the bit becomes bound in the workpiece, release the trigger immediately, reverse the direction of rotation and slowly squeeze the trigger to back out the bit. Be ready for a strong reaction torque. The drill body will tend to twist in the opposite direction as the drill bit is rotating.
Do not grasp the tool or place your hands too close to the spinning chuck or drill bit. Your hand may be lacerated.
When installing a drill bit, insert the shank of the bit well within the jaws of the chuck. If the bit is not inserted deep enough, the grip of the jaws over the bit is reduced and the loss of control is increased.
