How do you Add hydraulic fluid to barber chair step by step?

To add hydraulic fluid to a barber chair, first, locate the hydraulic pump under the chair, typically accessible from the bottom. Next, remove the fill cap or rubber plug from the pump. Using a funnel, carefully pour the appropriate hydraulic fluid into the reservoir until it reaches the recommended level, then replace the fill cap securely. Finally, test the chair's height adjustment to ensure it operates smoothly.
