Service 72 & Calibration

Grettz Precision – Service 72

Fast. Accurate. Guaranteed.
At Grettz, we know your time is valuable. That’s why we created Service 72—our premium calibration and servicing program that ensures your laser level is back to peak performance in just 72 hours.

1. Why Calibration is Important

Calibration ensures the laser projects a level or plumb line within the manufacturer’s specified tolerance. Over time, transportation, vibrations, and heavy use can cause slight misalignments.

2. When to Check Calibration

• Every 6 - 12 months (regular maintenance).
• After the tool has been dropped or subjected to impact.
• If the laser lines appear uneven or inaccurate.
• Before critical levelling tasks.

3. If Adjustment is Needed

• Do not attempt internal adjustments unless you are a trained technician.
• Purchase the Grettz service and warranty package. 
• Warranty may be void if unauthorized calibration is attempted.

4. Professional Calibration Service

If your laser level is out of tolerance, please purchase the calibration service. It is your responsibility to get the laser level returned to us, we recommend using royal mail or www.parcel2go.com . Once we have the laser level back with us we will get it calibrated and returned to you within 72 hours.
