5. Operating Instructions
This section details the steps for sharpening circular saw blades using the machine.
General Operation:
- Mount the Saw Blade: Place the circular saw blade onto the blade support spindle. Use appropriate spacers and washers to ensure the blade is centered and secure.
- Adjust Blade Feed Angle: Use the ring-type saw blade support to adjust the blade feed angle. This can be set from 30° left to 45° right. Refer to the precise scales for accurate adjustment.
- Adjust Grinding Wheel Angle: Adjust the angle of the grinding wheel by ±20° to match the tooth geometry of your saw blade.
- Position Blade for Sharpening: Carefully move the blade support to bring the first tooth into contact with the grinding wheel. Ensure only light contact is made.
- Activate Water Cooling: Ensure the water flow from the tank to the grinding wheel is active.
- Start the Machine: Press the ON button on the waterproof switch. The motor will start, and the grinding wheel will rotate at 2850 rpm.
- Sharpening Process: Gently feed each tooth into the grinding wheel, applying minimal pressure. Sharpen each tooth uniformly. Repeat for all teeth.
- Stop the Machine: Once all teeth are sharpened, press the OFF button on the switch.
- Remove Blade: Disconnect power, then carefully remove the sharpened saw blade.
