1. Tools Needed: Grease gun, precision brush, cleaning cloth, gloves (to avoid contamination).
2. Safety First: Power off the Lectra machine before lubrication; ensure the lubrication area is clean and free of debris to prevent mixed contamination.
3. Application Preparation: Clean the surface of moving parts (guide rails, gears, shafts) with a dry cloth to remove old grease, dust, and fabric residues.
4. Lubrication Operation: Apply an appropriate amount of 118010 G3 grease to the target parts—use a grease gun for guide rails and blades, a brush for gears and shafts; avoid over-lubrication to prevent oil stains on fabrics.
5. Post-Application Check: Run the machine for 1-2 minutes after lubrication to ensure uniform grease distribution; wipe off excess grease with a clean cloth.
6. Maintenance Schedule: Lubricate cutting machine parts every 200 operating hours, sewing unit parts every 300 operating hours; store unused grease in a cool, dry environment (23℃ recommended) with a shelf life of 60 months.
7. Warranty Note: The 118010 G3 lubricating grease comes with a 6-month warranty; contact us immediately for replacement if quality issues (e.g., deterioration, abnormal viscosity) occur within the warranty period.
8. Tools Needed: Precision screwdriver set, multimeter (for calibration), cleaning cloth, anti-static gloves.
9. Safety First: Power off and lock out the Lectra machine before installing/replacing the force sensor; wear anti-static gloves to avoid damaging electronic components.
10. Replacement Preparation: Remove the old force sensor; clean the installation area and connecting terminals to remove dust, debris, and oxidation.
11. Install New 702849 Sensor: Align the sensor with the mounting points; securely fasten and connect the terminals per Lectra’s service manual to ensure stable signal transmission.
12. Calibration: After installation, use a multimeter to calibrate the force sensor according to the machine’s standard parameters; test operational force detection to ensure accuracy.
13. Maintenance: Inspect the sensor and terminals monthly for loose connections or damage; clean with a dry cloth (avoid liquid cleaners) to prevent signal interference.
14. Warranty Note: The 702849 force sensor comes with a 6-month warranty; contact us immediately for replacement or technical support if quality issues occur within the warranty period.
