2. 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.
2.1 Work Area Safety
- Keep 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.
2.2 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.
2.3 Personal Safety
- Always wear eye protection. Use appropriate personal protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection for appropriate conditions.
- Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
- Prevent unintentional starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the tool.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
2.4 Power Tool Use and Care
- Do not force the power tool. Use the correct power tool for your application.
- Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
- Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
- Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
- Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use.

6. Operating Instructions
6.1 Selecting Operating Mode
The rotary hammer drill features four functional modes, selected by rotating the mode selector knob.
- Drilling Mode: For drilling in wood, metal, and plastic without hammer action.
- Hammer Drilling Mode: Combines rotation and hammer action for drilling in concrete and masonry.
- Chiseling Mode: For chiseling applications in concrete and masonry without rotation.
- Chiseling Angle Adjustment Mode: Allows adjustment of the chisel's angle for optimal working position.

6.2 Variable Speed Control and Forward/Reverse Switch
- Variable Speed Trigger: The tool's speed is controlled by the pressure applied to the trigger. Pressing lightly results in lower speed, while pressing fully increases speed. This allows for precise control, especially when starting a hole.
- Forward/Reverse Switch: Located above the trigger, this switch controls the direction of rotation. Push it left for forward rotation (drilling/chiseling) and right for reverse rotation (e.g., removing a stuck drill bit). Ensure the tool is stopped before changing direction.
6.3 Using the Depth Ruler
The included depth ruler helps achieve consistent drilling depths.
- Insert the depth ruler into the designated hole on the auxiliary handle.
- Adjust the ruler to the desired drilling depth, measuring from the tip of the drill bit.
- Tighten the auxiliary handle to secure the depth ruler in place.
- Drill until the end of the depth ruler touches the workpiece surface.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your tool.
- Cleaning: After each use, clean the tool with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep ventilation openings clear of dust and debris.
- Chuck Maintenance: Periodically clean the SDS Plus chuck to remove dust and debris. Apply a small amount of SDS grease to the bit shank before insertion to reduce wear.
- Battery Care: Store batteries in a cool, dry place. Do not store fully discharged batteries for extended periods.
- Inspection: Regularly inspect the power cord (if applicable), housing, and accessories for any signs of damage or wear. Replace damaged parts immediately.
- Storage: Store the tool and accessories in a dry, secure location, out of reach of children.
