Observe before taking action
Carefully observe the fault symptoms and record the error codes and alarm messages. Avoid blind disassembly.

Start with simple checks before moving to complex ones
First inspect external components such as the power supply, wiring, and switches, then proceed to check internal mechanisms if necessary.

Power off before maintenance
Always disconnect the machine’s main power supply before performing maintenance. Place warning signs to prevent electric shock accidents.

Key Points for Routine Maintenance
1-Check turret lubrication daily and apply dedicated grease once a week.
2-Clean metal chips and oil contamination from the signal disc once a month to maintain reliable signal detection.
3-Check turret clamping force and positioning accuracy every quarter, and adjust clearances as needed.
