1. Safety Information
Always read and understand 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.
General Power Tool Safety Warnings
- 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.
- 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.
- Personal Safety: 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. A moment of inattention while operating power tools may result in serious personal injury.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools.
- Service: Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

3. Setup and Assembly
3.1 Attaching the Auxiliary Handle
The auxiliary handle can be rotated 360 degrees around the chuck housing for optimal positioning. Loosen the handle by twisting it counter-clockwise, position it as desired, and then tighten by twisting clockwise until secure.
3.2 Installing the Depth Rod
Insert the depth rod through the hole in the auxiliary handle. Adjust its position to the desired drilling depth. The depth rod allows for precise, repeatable drilling depths.
3.3 Inserting and Removing Drill Bits
- Ensure the drill is unplugged from the power source.
- Open the chuck jaws by rotating the chuck key (if applicable) or by hand (if keyless chuck) counter-clockwise.
- Insert the drill bit fully into the chuck.
- Tighten the chuck jaws by rotating clockwise until the bit is firmly secured. For keyed chucks, use the chuck key to ensure maximum grip.
- To remove, reverse the tightening process.
4. Operating Instructions
4.1 Selecting Operating Mode
This hammer drill offers two modes: drilling and hammer drilling. Use the mode selector switch located on the side of the drill to choose the appropriate mode:
- Drill Mode: For drilling into wood, metal, plastics, and other non-masonry materials.
- Hammer Drill Mode: For drilling into masonry, concrete, and brick. This mode combines rotary action with a hammering action.
4.2 Variable Speed Control
The drill features a variable speed trigger. The speed of rotation increases as you apply more pressure to the trigger. This allows for precise control, especially when starting a hole or working with different materials.
4.3 Forward/Reverse Rotation
The forward/reverse switch, typically located above the trigger, controls the direction of rotation. Push the switch to the left for forward (clockwise) rotation for drilling and driving screws. Push it to the right for reverse (counter-clockwise) rotation for removing screws or freeing jammed bits.
4.4 Using the Lock-on Button
For extended periods of drilling, you can engage the lock-on button. Press the trigger fully, then press the lock-on button. Release the trigger, and the drill will continue to operate. To disengage, press the trigger fully again and release.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your hammer drill.
- Cleaning: After each use, clean the tool's ventilation openings and housing with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Chuck Maintenance: Periodically clean the chuck jaws to ensure proper grip on drill bits. Apply a small amount of light machine oil to the chuck jaws if they become stiff.
- Carbon Brushes: This tool uses carbon brushes. If the motor sparks excessively or the tool loses power, the carbon brushes may need replacement. This should be performed by a qualified service technician.
- Storage: Store the tool in a dry, secure place out of reach of children. Protect it from direct sunlight and extreme temperatures.
- Cord Inspection: Regularly inspect the power cord for any damage, cuts, or fraying. If damaged, have it repaired by a qualified professional to prevent electrical hazards.
