Safety Rules for Cordless Drill / Drivers

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.

Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

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.

Always hold the tool with both hands. If the bit jams two hands will give you maximum control over torque reaction or kickback.

Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.

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 bit, insert the shank of the bit well within the chuck. If the bit is not inserted deep enough, the grip of the chuck over the bit is reduced and the loss of control is increased. After bit insertion, pull on bit to ensure it is locked.

Do not use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to bind in the workpiece.

When removing the bit from the tool avoid contact with skin and use proper protective gloves when grasping the bit or accessory. Accessories may be hot after

prolonged use.

Check to see that keys and adjusting wrenches are removed from the drill before switching the tool "ON". Keys or wrenches can fly away at high velocity striking you or a bystander.

Do not run the drill while carrying it at your side. A spinning drill bit could become entangled with clothing and injury may result.

!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.

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.
