Using the product in confined work areas may put you dangerously close to cutting tools and rotating parts. Do not use the product where there is a risk of causing a fire or an explosion; e.g., in the presence of flammable liquids, gases, or dust.
Check for damaged parts before each use. Carefully check that the product will operate properly and perform its intended function. Replace damaged or worn parts immediately. Never operate the product with a damaged part. Do not use a product with a malfunctioning switch. Any power tool that cannot be controlled with the power switch is dangerous and must be repaired by an authorized service representative before using.
Grounding ⚠WARNING This machine must be grounded while in use to protect the operator from electrical shock. This unit is equipped with an electrical cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching receptacle that is properly installed and grounded in accordance with ALL local codes and ordinances. DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper receptacle installed by a qualified electrician.
Extension Cords ⚠WARNING USE A PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw.

Do not use fly cutters or multiple-part hole cutters, because they can come apart or become unbalanced during use. Do not drill material too small to be securely held. Use only well-sharpened bits that are in good condition and appropriate for the task.
Wood Drilling 1. Secure the workpiece. 2. Start by drilling slowly to keep the bit from moving away from the start point. 3. Increase the hammer drill’s speed as the hole is established. 4. To prevent or reduce “tear out” when the bit exits the far side of the work piece, clamp a piece of scrap material to the back of the work piece. 5. DO NOT lock the trigger in the ON position, as the bit can easily jam in the wood. You should always be able to stop the motor quickly. Masonry Drilling 1.
