How To Add Hydraulic Fluid To Barber Chair

Understanding Why Hydraulic Fluid Matters

Hydraulic fluid is essential for the lifting mechanism of a Barber Chair. It allows smooth pumping, stable height adjustment, and controlled lowering. When the fluid level becomes low or contaminated, the chair may fail to rise, sink slowly, or feel unstable. High-quality hydraulic systems—like those used by Huiyi Furniture—are designed for long-term performance, but periodic maintenance such as fluid refilling keeps the mechanism working efficiently.

Signs Your barber chair Needs Hydraulic Fluid

1. Chair Slowly Sinks While in Use

Low or weakened fluid pressure cannot hold the weight.

2. Chair Fails to Lift When Pumped

Insufficient fluid prevents the piston from moving upward.

3. Pump Pedal Feels Soft or Weak

Indicates air inside the hydraulic system.

4. Visible Oil Leaks Around the Base

Fluid may be escaping from seals or gaskets.

5. Inconsistent Lifting Height

Loss of hydraulic integrity reduces performance.

Tools and Materials You Will Need

• Hydraulic fluid (ISO 32 or manufacturer-recommended grade)

• Screwdriver or Allen key

• Funnel with narrow spout

• Clean cloth

• Gloves

• Container for potential spills

Avoid using automotive brake fluid or non-hydraulic oils, as they damage seals inside the pump.

Step-by-Step Guide: How to Add Hydraulic Fluid to a barber chair

Step 1: Lower the Chair Completely

Pump the release pedal to bring the chair to its lowest position.
This reduces internal pressure and makes refilling safer.

Step 2: Access the Hydraulic Pump

Tilt the chair forward or backward depending on the model, exposing the hydraulic cylinder.

You should locate:

• The fill plug or screw (usually near the top of the cylinder)

• The pump unit housing

Huiyi Furniture designs their bases with accessible fill ports for easier maintenance.

Step 3: Remove the Fill Plug

Use a screwdriver or Allen key to unscrew the plug.

Precaution:

Wipe the area clean before opening to prevent contamination.

Step 4: Add Hydraulic Fluid

Insert a funnel and pour fluid slowly into the cylinder.

Guidelines:

• Fill only until the fluid reaches the opening

• Avoid overfilling, which may cause pressure issues

• Pour slowly to prevent air bubbles entering the system

Hydraulic systems require clean, bubble-free fluid for optimal lifting power.

Step 5: Replace the Fill Plug Securely

Once the fluid is added:

• Remove the funnel

• Clean any spilled fluid

• Tighten the fill plug firmly

A tight seal prevents leaks and keeps air from entering the system.

Step 6: Pump the Pedal to Circulate the Fluid

Raise and lower the chair several times.

Purpose:

• Expels trapped air inside the pump

• Distributes new fluid throughout the cylinder

• Restores smooth lifting action

If the chair still feels weak after several pumps, repeat the process.

Step 7: Inspect for Leaks

Check the base and pump area.

Look for:

• Drips on the floor

• Wet patches around seals

• Fluid escaping when raising the chair

If leaks persist, seals or the cylinder may require replacement.

Common Mistakes to Avoid

1. Using the Wrong Type of Fluid

Non-hydraulic oils damage internal seals.

2. Overfilling the Cylinder

Creates pressure imbalance and may cause leaks.

3. Ignoring Air Bubbles

Air inside the system reduces lifting power.

4. Not Cleaning the Fill Area

Dirt entering the pump can cause long-term damage.

5. Forgetting to Tighten the Fill Plug

Leads to immediate fluid loss during use.

How Huiyi Furniture Improves Hydraulic System Reliability

Huiyi Furniture enhances traditional hydraulic designs by incorporating:

• Reinforced high-grade cylinders

• Durable internal seals resistant to wear

• Stable, weight-balanced bases

• Smooth pump-action pedals

• User-friendly access ports for maintenance

These improvements help minimize fluid loss and ensure the chair remains reliable through daily heavy use.

Maintenance Tips for Long-Term Performance

Check Fluid Levels Twice a Year

Prevent performance issues before they occur.

Clean the Pump Area Regularly

Removes hair and debris that can interfere with movement.

Keep Weight Within Load Capacity

Protects hydraulic seals and internal pressure systems.

Lubricate External Mechanisms

Supports the recline and swivel systems even though they are separate from hydraulics.

Replace Worn Seals Immediately

Avoids gradual fluid loss and weak lifting.
