• Regular Cleaning

  • Wipe down the table and fence regularly to remove dust, wood chips, and debris.
  • Use a vacuum or compressed air to clean out the dust collection system and surrounding areas to prevent clogs.

• Inspect and Maintain Straight Knives:

  • Periodically inspect the straight knives for dullness or damage. Rotate or replace them as necessary to maintain cutting precision.
  • Ensure the knives are properly aligned with the cutterhead for even cutting and smooth operation.

• Lubricate Parallelogram Mechanism and Bed:

  • Apply a light lubricant to the parallelogram mechanism and bed rails to ensure smooth height adjustments.
  • Check that the table height adjustment system operates freely, and adjust handles as needed.

• Check and Adjust the Fence:

  • Inspect the fence for proper alignment with the table. Ensure the fence is securely locked in place during operation.
  • Clean the fence and inspect for any damage, adjusting it to maintain square alignment with the table.

• Motor and Electrical Inspection:

  • Ensure the motor is securely mounted and running smoothly without excessive vibration or noise.
  • Inspect electrical components for any signs of wear or damage, and verify proper function of the power switch.

• Dust Collection System Maintenance:

  • Check the dust collection port and hose for blockages. Clean out the system as needed to ensure optimal dust extraction.
  • Empty the dust collection container regularly to prevent overfilling and ensure efficient operation.

• Check Table Alignment:

  • Periodically inspect the infeed and outfeed tables for levelness and ensure they are parallel to the cutterhead for smooth cuts.
  • Adjust the tables as necessary to maintain proper alignment and precision.

• Tighten Loose Bolts and Fasteners:

  • Inspect the machine for loose bolts, screws, or fasteners. Tighten any loose parts to ensure the machine remains stable and operates safely.
