General Safety Instructions
Always follow basic safety precautions when using electric tools to reduce the risk of fire, electric shock, and personal injury. Keep your work area clean and well-lit. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Always wear appropriate personal protective equipment, including eye protection, hearing protection, and a dust mask.
- Power Supply: Ensure the power supply matches the specifications on the tool's nameplate.
- Secure Workpiece: Always secure the workpiece firmly to prevent movement during planing.
- Keep Hands Clear: Keep hands and fingers away from the planing blades.
- Unplug When Not in Use: Disconnect the planer from the power source before making any adjustments, changing accessories, or storing the tool.
- Automatic Parking Shoe: The planer features an automatically folding parking shoe to prevent damage to the workpiece or the planer blade when resting the tool.
Setup
1. Unpacking
- Carefully remove the planer and all accessories from the packaging.
- Inspect the tool for any signs of damage that may have occurred during transit. Do not operate a damaged tool.
- Verify that all components listed in the "Components Included" section are present.
2. Blade Installation and Adjustment
The Bosch PHO 20-82 uses reversible carbide planer blades. The patented Woodrazor blade system ensures easy and quick blade changes.
- Ensure the planer is unplugged from the power source.
- Using the provided hex key, loosen the screws securing the planer blade.
- Carefully remove the old blade. Caution: Blades are extremely sharp.
- Insert the new reversible blade, ensuring it is correctly seated and aligned.
- Tighten the screws securely with the hex key.
- Repeat for the second blade if necessary.
3. Dust Extraction
The planer features an optimized chip ejection system to prevent chip blockages. Chips can be ejected to either the left or right side.
- Connect a dust bag or a vacuum cleaner to the chip ejection port for cleaner operation.
- Use the chip deflector switch (if present) to direct chips to the desired side.
Operating Instructions
1. Power Connection
Connect the planer's power cable to a suitable electrical outlet. Ensure the voltage matches the tool's requirements.
2. Adjusting Planing Depth
The planing depth can be continuously adjusted from 0 to 2.0 mm using the front knob.
- Rotate the front adjustment knob to set the desired planing depth. The scale indicates the depth in millimeters.
- Start with a shallow depth for initial passes and increase gradually if needed.
3. Starting and Stopping
- To start the planer, press the safety lock-off button (usually located on the handle) and then press the ON/OFF trigger switch.
- To stop the planer, release the ON/OFF trigger switch.
- Allow the blades to come to a complete stop before setting the tool down.
4. Planing Technique
- Place the front shoe of the planer flat on the workpiece.
- Start the planer and allow it to reach full speed before moving it across the workpiece.
- Apply even pressure and move the planer smoothly and consistently over the surface.
- Avoid tilting the planer during operation to ensure a uniform finish.
5. Chamfering Edges
The Bosch PHO 20-82 features a V-groove in the front shoe for precise chamfering of edges.
- Place the V-groove over the edge of the workpiece.
- Guide the planer along the edge to create a chamfer.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your planer. Always unplug the tool before performing any maintenance.
1. Cleaning
- After each use, clean the planer thoroughly.
- Remove any accumulated dust and chips from the chip ejection port and around the blades. The optimized chip ejection system helps prevent blockages, but manual cleaning may still be necessary.
- Use a soft brush or compressed air to clean ventilation openings.
- Do not use water or chemical cleaners.
2. Blade Replacement
Replace blades when they become dull or damaged. Refer to the "Blade Installation and Adjustment" section for detailed steps. Always use genuine Bosch replacement blades.
3. Storage
Store the planer in a dry, secure location, out of reach of children. Ensure the power cord is neatly coiled and not kinked.
