1. Important Safety Instructions

Read all safety warnings and instructions before operating this power tool. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury. Save all warnings and instructions for future reference.

Work Area Safety

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

Personal Safety

• Always wear eye protection. Use safety glasses, goggles, or a face shield.
• Wear hearing protection when operating the hammer drill.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.

5.2 Selecting Drill Mode (2-in-1 Function)

The hammer drill offers two primary modes: drilling and hammer drilling.

Figure 5.2: Demonstrating 2-in-1 function mode for various materials.

• Drill Mode (Rotation Only): For drilling into wood, metal, plastics, and other materials that do not require impact. Set the hammer action selector to the drill icon.
• Hammer Drill Mode (Rotation with Impact): For drilling into concrete, brick, and masonry. Set the hammer action selector to the hammer icon. Use appropriate masonry drill bits.

5.3 Drilling Tips for Various Materials

Always use the correct drill bit for the material you are working with.

Figure 5.3: Examples of drilling applications on different materials.

• Wood: Use wood drill bits. Start with a slow speed to prevent splintering, then increase.
• Metal: Use metal drill bits. Apply cutting oil to cool the bit and material. Start with a pilot hole for larger diameters.
• Concrete/Masonry: Use masonry drill bits and hammer drill mode. Apply steady pressure.
• Plastics: Use wood or metal drill bits. Use low speed to prevent melting or cracking.
