2. Safety Instructions

Always observe general safety regulations when working with power tools. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.

• Work Area Safety: Keep the 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.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators.
• Personal Safety: Always wear eye protection (safety glasses or goggles) and hearing protection. Use a dust mask if grinding operations create dust. Do not overreach. Keep proper footing and balance at all times.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
• Maintenance: Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation.

This machine operates on 400V. Ensure proper electrical installation and grounding by a qualified electrician.

4. Setup

1. Unpacking: Carefully remove the machine from its packaging. Inspect for any shipping damage. Report any damage immediately to your supplier.
2. Mounting: Securely mount the bench grinder to a stable workbench using appropriate bolts and washers. Ensure the mounting surface can support the machine's weight (approximately 34 kg) and withstand operational vibrations.
3. Electrical Connection: Connect the machine to a 400V power supply. Ensure the electrical circuit is properly fused and grounded. If unsure, consult a qualified electrician.
4. Install Grinding Belt (if not pre-installed):
   • Loosen the tension lever for the belt grinding arm.
   • Slide the new 915 x 100 mm grinding belt onto the rollers, ensuring the directional arrow on the belt matches the machine's rotation.
   • Re-engage the tension lever to secure the belt.
5. Install Grinding Disc (if not pre-installed):
   • Ensure the machine is unplugged.
   • Mount the 200 x 32 x 32 mm grinding wheel onto the spindle, securing it with the provided flange and nut. Do not overtighten.
6. Adjust Work Rests: Adjust the work rests for both the belt and disc grinding stations to a safe and appropriate distance from the grinding surface (typically 1-2 mm).

5. Operating Instructions

1. Pre-Operation Check: Before each use, inspect the grinding belt and disc for wear, damage, or cracks. Ensure all guards and work rests are securely in place.
2. Power On: Connect the machine to the power supply and switch it on. Allow the machine to reach full operating speed before beginning any grinding task.
3. Using the Belt Grinder:
   • Adjust the tilt of the belt arm (0° to 90°) as needed for your workpiece. The 45° tilt support can be used for common angles.
   • Hold the workpiece firmly against the work rest and gently bring it into contact with the moving grinding belt. Apply even, moderate pressure.
   • Move the workpiece across the belt to ensure even material removal and prevent overheating of the workpiece or belt.
4. Using the Disc Grinder:
   • Hold the workpiece firmly against the work rest.
   • Bring the workpiece into contact with the rotating grinding disc, typically on the side where the disc is moving downwards towards the work rest. This helps prevent the workpiece from being thrown upwards.
   • Apply light, consistent pressure and move the workpiece to avoid concentrating heat in one spot.
5. Power Off: After completing your task, switch off the machine and wait for all moving parts to come to a complete stop before leaving the work area or performing any adjustments.

6. Maintenance

• Grinding Belt Replacement:
  • Unplug the machine.
  • Release the tension lever for the belt arm.
  • Remove the old belt and install a new 915 x 100 mm belt, ensuring correct direction.
  • Re-tension the belt.
• Grinding Disc Replacement:
  • Unplug the machine.
  • Carefully remove the retaining nut and flange.
  • Replace the worn disc with a new 200 x 32 x 32 mm grinding wheel.
