Please cut off the power and scrub the surface of the body in time after use to prolong the service life. 4.When the vibration noise suddenly increases during work, accompanied by abnormal sounds, it may be due to abnormal clearance between the vibration platform and the transformer. You need to cut off the power supply, peel off the rubber platform, turn the device upside down, and use a cross screwdriver to remove four M6 screws to separate the vibration platform from the body. Then check each of the four vibration columns for looseness or improper height. It is advisable to adjust the height to 68mm/2.68 inch, keeping the height of the four columns consistent and locking them tightly. (Adjusting tool: 10mm/0.39 inch opposite hexagonal socket wrench). 5.Please pay attention to electrical safety, take personal protective measures, and keep the product away from children.
