1. Important Safety Instructions
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.
- Work Area Safety: Keep your 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.
- 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
3.1 Attaching the Side Handle and Depth Gauge
The auxiliary side handle and depth gauge provide additional control and precision during operation. Always ensure they are securely attached before use.
- Loosen the side handle by turning it counter-clockwise.
- Slide the side handle onto the front of the drill housing.
- Insert the depth gauge into the hole on the side handle. Adjust it to the desired drilling depth.
- Rotate the side handle to the desired working position and tighten it securely by turning clockwise.
3.2 Inserting Drill Bits
Ensure the drill is unplugged before changing bits.
- Open the drill chuck jaws by turning the chuck key (if applicable) or by hand for keyless chucks.
- Insert the drill bit fully into the chuck.
- Tighten the chuck jaws securely around the drill bit. For keyed chucks, use the chuck key to tighten all three holes. For keyless chucks, hand-tighten firmly.
4. Operating Instructions
4.1 Powering On/Off and Speed Control
The PSB450RE features an electronic stepless speed control for precise operation.
- To Power On: Press the trigger switch. The drilling speed increases as you press the trigger further.
- To Power Off: Release the trigger switch.
- Continuous Operation: For continuous operation, press the trigger switch and then press the lock-on button (if available) while the trigger is depressed. To release, press the trigger again.
4.2 Forward/Reverse Rotation
The forward/reverse switch allows for easy change of rotation direction, useful for screw driving or removing jammed bits.
- Locate the forward/reverse switch near the trigger (refer to Figure 2.3).
- Push the switch to the left for forward rotation (clockwise).
- Push the switch to the right for reverse rotation (counter-clockwise).
- Always ensure the tool has come to a complete stop before changing the rotation direction.
4.3 Drilling Mode Selection
The PSB450RE offers two drilling modes: rotary drilling and vibration drilling.
- Rotary Drilling (Drill Symbol): Use this mode for drilling in wood, metal, plastics, and for screw driving.
- Vibration Drilling (Hammer Symbol): Use this mode for drilling in masonry, concrete, and stone.
- To select a mode, rotate the large changeover lever located on the top of the drill housing (refer to Figure 2.4) to align with the desired symbol.
4.4 Drilling Applications Guide
Select the appropriate drill bit and mode for your material.

Figure 4.1: Guide for selecting the correct drill type and mode for various materials and tasks.
- Wood: Use HSS drill bits or wood drill bits. Use rotary drilling mode.
- Metal: Use HSS drill bits. Use rotary drilling mode. Apply cutting oil for harder metals.
- Concrete/Masonry: Use carbide-tipped masonry drill bits. Use vibration drilling mode.
- Screw Driving: Use appropriate screwdriver bits. Use rotary drilling mode and lower speeds.
5. Maintenance
