How do you put hydraulic fluid in a barber chair?

To add hydraulic fluid to a barber chair, first, locate the hydraulic pump beneath the chair. Remove the cap or plug from the fill port, typically found on the top or side of the pump. Using a funnel, carefully pour the appropriate hydraulic fluid into the fill port until it reaches the recommended level, then replace the cap securely. Always consult the chair's manual for specific instructions and the correct type of fluid.
