GRABO PRO Troubleshoot
GRABO® Pro-Lifter 20 learning mode / recalibration mode :
Place the GRABO Pro-Lifter 20 on a non-porous surface such as a polished tile.
Slide the power ON/OFF switch in the ON position.
- Press the "measurement unit selector" for 10 seconds. When the red light turns green, release the "measurement unit selector"
- Wait about 5 seconds and the vacuum pump will start working. Let the device create full suction. If suction does not begin on its own, press the device downward to create a seal. Full suction is achieved when the digital display numbers have reached their highest point and don't continue to increase.
- When full suction is reached, press the "measurement unit selector" again for 3 seconds until the green light flashes and the pump turns off.
- Turn the device off and on again with the the power ON/OFF switch.
*The device is now calibrated and the values in the digital display window should be correct.
Important : The GRABO Pro-Lifter 20 will display incorrect values on the digital display if the device is not calibrated on a non-porous surface such as tile or glass. If this occurs, the calibration process must be repeated on a non-porous material. DO NOT perform this process on glass that is thinner than 6mm. Damage can occur to glass that is thinner than 6mm.
