The pump brake is an important part of Maletti furniture because it allows armchairs to be adjusted according to needs. Setting it and arranging it correctly is therefore fundamental in order to be able to work easily and allow the customer to be comfortable during treatment. Among the necessary instruments: - 2 x 16" wrenches (possibly long) - Philips screwdriver - Spring clamp Instructions follow for carrying out this operation: 1. Raise the chair to its maximum height 2. Unscrew the chrome-plated crankcase and lock it on the stem using a spring clamp 3. Check the status of the pump components. If the components are intact, check the status of the regulating nuts 4. Try the brake application again 5. If the brake doesn’t work, you need to adjust the nuts 6. Using the wrenches, hold nut number 1 and unscrew lock nut number 2 7. Once the lock nut is free, tighten nut number 1 just enough to operate the brake 8. Once the right setting has been found, check that the brake is working properly 9. Tighten nut number 2 while holding nut number 1 10.
