Use hydraulic jack oil, available pretty much anywhere - I used Johnson's, 1qt bottles are $7.99 at my local O'Reilly.
To fill, or replace, the fluid you'll first remove the seat cushion. It should just lift off. Under that there will be a hole in the center of the base, it may or may not be covered by a plastic cap or a screw on older models.
Remove the cap to access the fluid reservoir. I would suggest removing as much existing fluid as you can before adding more, to avoid overfilling the pump. You can find a suction gun at harbor freight for about $15 which you can use to remove as much of the fluid in the chair as possible, without having to disassemble the pump mechanism. Place your control lever in the full down position, this will allow clear access to feed in the suction tube, as well as assure the chair is fully "down" and thus the reservoir as full as possible.
Once empty, refill with hydraulic jack oil. Add one quart to start, and pump the chair up. If it gurgles while raising and before topping out, or when lowering, lower and add another 2-4oz and repeat the process until it makes no liquid noises when being raised, and doesn't gurgle or gush when being lowered.
If you add too much fluid, the seals may be damaged and/or the chair will be very difficult to lower after being raised. Also do not EVER use any oil/fluid which mentions "stop leak".
To add hydraulic fluid to a Koken barber chair, locate the hydraulic pump, usually found under the seat or beneath the chair base. There should be a fill port or plug that can be removed; use a suitable hydraulic fluid to fill it to the recommended level. Always refer to the manufacturer's manual for specific instructions and fluid type to ensure proper maintenance and functionality.
Hydraulic oil.
Belmont barber chairs typically use a hydraulic fluid that is specifically designed for hydraulic systems, often a type of mineral oil or a biodegradable hydraulic fluid. It's important to refer to the manufacturer's specifications for the exact type of fluid recommended for optimal performance and to ensure compatibility with the chair's hydraulic mechanisms. Regular maintenance and fluid checks are essential to keep the chair functioning smoothly.
Paidar barber chairs typically use a hydraulic fluid that is non-toxic and compatible with the hydraulic systems employed in their construction. Commonly, a mineral oil-based hydraulic fluid or a specific hydraulic oil recommended by the manufacturer is used. It's essential to refer to the chair's manual or manufacturer's specifications for the exact type and viscosity of hydraulic fluid required for optimal performance.
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.

Barber chairs are often raised and lowered using gas or hydraulic struts. These struts work by using strong springs or pressurized gas. Some of these devices can be recharged, or have replaceable seals, but others are disposable items that are replaced as a unit.
There are two chambers an upper and a lower. If the chair is all the way down the fluid is in the upper chamber. When the barber selects the chair to go up the fluid from the top is forced through a metering valve to the lower chamber. As the lower chamber fills the chair moves up into the space that is vacated in the upper chamber.
The amount of oil required for a Hercules barber chair hydraulic pump typically varies by model, but it generally ranges from 1 to 3 quarts. It's important to consult the specific chair's manual for detailed specifications and recommendations. Always ensure to use the appropriate hydraulic fluid for optimal performance.
Check the hydraulic fluid. Hydraulic cylinder piston rubber washers to replace.
A light push on the lever of a hydraulic barbershop chair transfers force to a small piston, creating pressure in the hydraulic fluid. This pressure is transmitted to a larger piston connected to the chair, amplifying the force and allowing it to lift a person in the chair with minimal effort.
