2.3 Mounting Drill Bits
The drill supports both SDS-Plus bits and standard drill bits using a chuck adapter.
2.3.1 For SDS-Plus Drill Bits:
- Clean the shank of the SDS-Plus drill bit.
- Pull back the collet (blue part) on the drill head.
- Insert the SDS-Plus drill bit into the chuck until it clicks into place.
- Release the collet and gently pull on the drill bit to ensure it is securely locked.
2.3.2 For Standard Drill Bits (using clamp drill bit adapter):
The product's original drill is plug and play. For other small drills, a clamp drill bit adapter is required.
- Assemble the clamping drill bit adapter and connecting rod.
- Insert the assembled adapter into the SDS-Plus chuck as described above.
- Insert the desired standard drill bit into the clamp drill bit adapter.
- Tighten the drill bit using the chuck key. The same applies when disassembling.
2.4 Oiling the Gearbox
Regular lubrication is crucial for the longevity and performance of your rotary hammer drill.
- Locate the oil cover on the top of the drill (refer to the labeled diagram).
- Use the provided wrench to open the oil cover.
- Apply a small amount of advanced lubricant (included) into the gearbox.
- Close the oil cover securely with the wrench.
3. Operating Instructions
3.1 Powering On/Off
To turn the drill on, press the trigger switch. To turn it off, release the trigger switch.
3.2 Mode Selection
The DayPlus Rotary Hammer Drill offers four operating modes, selected via the function switch key (refer to the labeled diagram).
- Hammer/Drill Mode: For drilling with impact, suitable for punching holes in cement, walls, ceramic tiles, floor slabs, etc.
- Drill Mode: For standard drilling without impact.
- Rotation-Chiselling Mode: For chiselling with rotation.
- Electric Pick Mode (Chisel Lock/Roto-Stop): For chiselling without rotation, suitable for cement/wall dismantling and wall excavation for wiring. Rotate the paddle to the left before use.
3.3 Speed Adjustment
The drill features a speed adjustment dial, typically located near the trigger, allowing for 0-6 gear speed control. Adjust the speed according to the material and task requirements.
3.4 Safety Clutch
The integrated safety clutch protects the user and the tool in case the drill bit jams. If the bit binds, the clutch will disengage the drive, preventing sudden torque reactions.
3.5 Vibration Control System
The drill is designed with a Control Vibration System to reduce user fatigue and improve handling during extended use.
