3. General Safety Instructions

WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

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.
• 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.
• Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts.

Personal Safety

• Always wear eye protection. Use safety glasses, goggles, or a face shield.
• Wear appropriate personal protective equipment (PPE) such as hearing protection, dust mask, non-skid safety shoes, and work gloves.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.

5. Operating Instructions

Always wear appropriate safety gear, including eye protection and hearing protection, before operating the tool.

5.1 Selecting Operating Mode (Function Selector)

The tool offers three operating modes:

• Drill Mode: For drilling into wood, metal, and plastics.
• Hammer Drill Mode: For drilling into masonry, concrete, and brick.
• Screwdriver Mode: For driving and removing screws.

To select a mode, rotate the function selector switch located on the top of the tool to the desired icon. Ensure the selector clicks into place.

5.2 Adjusting Speed (Mechanical Speed Selector and Variable Speed Control)

• Mechanical Speed Selector: Use the switch on the top of the tool to select between high (II) and low (I) mechanical speed ranges. Low speed provides higher torque, suitable for larger holes or screwdriving. High speed is for smaller holes and faster drilling.

5.3 Reversible Function

The reversible lever, located near the trigger, controls the direction of rotation.

• Push the lever to the left for forward (clockwise) rotation, used for drilling and driving screws.
• Push the lever to the right for reverse (counter-clockwise) rotation, used for removing screws or freeing jammed drill bits.

Note: Always ensure the tool has come to a complete stop before changing the direction of rotation.
