4. Assembly and Setup
The Scheppach HS 120 Table Saw requires assembly. Due to the detailed nature of the assembly process, it is crucial to carefully follow the diagrams and instructions provided in the physical manual that accompanies your product. The following steps provide a general overview.
- Unpacking: Carefully unpack all components and verify against the parts list in your manual. Ensure no parts are missing or damaged.
- Assemble the Stand: Construct the sturdy, powder-coated sheet steel stand according to the diagrams. Ensure all bolts are securely tightened for stability. The stand includes a standard transport device (wheels) for mobility.
- Attach the Work Table: Mount the galvanized work table top to the assembled stand.
- Install the Saw Unit: Secure the main saw unit, including the motor and blade housing, to the underside of the work table.
- Install the Saw Blade: Carefully install the durable HW saw blade (Diameter 315 mm) onto the arbor. Ensure it is correctly oriented and secured with the appropriate fasteners.
- Attach Guards and Splitter: Install the blade guard and splitter. These are critical safety components and must always be in place during operation.
- Assemble Sliding Tray: Attach the sliding tray with ball bearing runners to the side of the main table. Ensure it moves smoothly along its 960 mm guide.
- Install Rip Fence and Table Extension: Mount the longitudinal stop (rip fence) with its eccentric clamp. Attach the table extension, which can also be used separately.
- Connect Dust Extraction: Attach the absaus hose with the central adapter connection for dust management.
- Initial Adjustments: Before first use, verify all alignments, including blade squareness to the table and fence, and blade tilt accuracy.
Note: The assembly process can be time-consuming. Refer to the detailed diagrams in your printed manual for precise component placement and fastening instructions.
5. Operation
Before operating the Scheppach HS 120 Table Saw, ensure all safety instructions have been read and understood, and the saw is properly assembled and adjusted.
- Power Connection: Connect the saw to a suitable 230V/50Hz power outlet. The induction motor features a soft start for smooth power-up.
- Adjusting Blade Height: Use the integrated hand wheel to easily adjust the height of the saw blade. Turn the wheel to raise or lower the blade to the desired cutting depth.
- Adjusting Blade Angle: The blade can be swiveled from 0° to 45° for miter cuts. Adjust the angle using the designated mechanism. Ensure it is securely locked at the desired angle before cutting.
- Using the Rip Fence: For rip cuts (cutting along the grain), position the longitudinal stop (rip fence) to the desired width. Secure it firmly with the eccentric clamp. Ensure the fence is parallel to the blade.
- Using the Sliding Tray: For cross-cuts (cutting across the grain) or precise miter cuts, utilize the sliding tray. Place the workpiece on the tray and guide it smoothly through the blade.
- Dust Extraction: Always connect a suitable dust extraction system to the absaus hose to minimize sawdust and maintain a clear work area.
- Making a Cut:
- Ensure the workpiece is stable and properly supported.
- Turn on the saw. Allow the blade to reach full speed before beginning the cut.
- Feed the workpiece slowly and steadily into the blade. Never force the material.
- Use a push stick or push block for narrow cuts or when your hands are close to the blade.
- After the cut, turn off the saw and wait for the blade to stop completely before removing the workpiece or off-cuts.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Scheppach HS 120 Table Saw. Always disconnect the saw from the power supply before performing any maintenance or cleaning.
- Cleaning:
- After each use, clean sawdust and debris from the work table, blade guard, and motor housing. Use a brush, vacuum, or compressed air.
- Ensure the sliding tray runners are free of debris for smooth operation.
- Never use solvents or abrasive cleaners that could damage plastic parts or painted surfaces.
- Blade Inspection and Replacement:
- Regularly inspect the saw blade for sharpness, cracks, missing teeth, or excessive wear. A dull blade can cause kickback and poor cut quality.
- Replace damaged or dull blades immediately. Refer to your manual for specific instructions on blade removal and installation. Always use blades of the correct diameter (315 mm) and arbor size.
- For finer cuts, consider using a blade with a higher tooth count than the standard blade provided.
- Motor and Electrical Components:
- Keep the motor's ventilation openings clean and free from obstructions to prevent overheating.
- Inspect the power cord and plug for any damage. Do not use the saw if the cord is frayed or damaged.
- Lubrication: Periodically apply a light machine oil to moving parts, such as the blade height adjustment mechanism and sliding tray runners, to ensure smooth operation. Avoid lubricating the blade itself.
- Fasteners: Periodically check all nuts, bolts, and screws for tightness. Vibration during operation can cause them to loosen.
