Osaki Master — Side Panel Removal Guide

Before You Move Your Chair

Removing the side panels makes your Osaki Master significantly easier and safer to transport. This guide walks you through each step with photos. The entire process takes about 15–20 minutes and requires only a Phillips screwdriver.

⚠️

Before you start: Power off the chair and unplug it from the wall. Allow the chair to return to the upright/home position before powering down.

What You'll Need

Phillips Screwdriver (#2)

Zip-lock bag for screws

Phone camera (for reference)

Tip: Take a photo of each step before disassembly so you have a reference during reassembly.

Overview

There are 2 phases to side panel removal. The hood must come off first to expose the side panel fasteners.

1Remove the Hood — top headpiece cover

2Remove the Side Panels — left side, then right side

Step-by-Step Procedure

Remove the Hood

Headpiece cover — 5 sub-steps

▼

ℹ️

The hood is the rounded cover on top of the headrest area. It houses the lampshade decorations and is secured by 4 screws plus a push-fit connection.

Remove the lampshade covers. On each side of the hood, locate the round lampshade. Rotate it counterclockwise and gently pat/pull to separate it from the hood.

Lampshade in place

Lampshade loosened after rotation

Disconnect the lampshade wiring. Once each lampshade is free, you'll see a small wiring connector behind it. Gently unplug the connector, then set the lampshade aside.

Connector unplugged

Remove the 4 mounting screws. With both lampshades off, you'll see 4 screws (2 on each side) securing the hood to the frame. Remove all 4 with a Phillips screwdriver.

Keep the screws in a labeled bag for reassembly.

Slide the hood off. With all 4 screws removed, push the hood outward to the left and right to release it from the frame. A slight rocking motion may help.

Push the hood outward to each side to release

Set the hood aside. Place it on a soft surface where it won't get scratched.

Remove the Side Panels

Left side first, then right side — 11 sub-steps

▼

Prerequisite: The hood must be removed first (Phase 1).

Steps A–E: Unfasten Both Side Panels

ℹ️

Steps A through E remove the fasteners that secure both side panels. Complete all five before lifting either panel off.

Open the decorative cover flap. On top of each side panel where the hood attached, there is a soft cover flap. Gently peel it back to reveal the mounting area underneath.

Peel back the decorative cover flap

Set the cover flap aside. The cover lifts off completely. Keep it with your other removed parts.

Disconnect the wiring connector and remove 10 screws from the back. From the rear of the chair, you'll see the side panel attached to the backrest frame. Unplug the wiring connector, then remove all 10 screws securing the panel.

Take a photo before you start so you can reference screw positions during reassembly.

Rear view — disconnect connector and remove all 10 screws

Remove 2 screws from the outer side. On the outer edge of each side panel, near the bottom where it meets the seat area, locate and remove 2 screws.

Remove 2 screws from under the seat. Looking at the front of the chair where the side panel meets the seat frame, locate and remove the final 2 screws — one on each side.

Steps F–H: Remove the Left Side Panel

Lift the left side panel straight upward. With all screws removed, grip the left side panel firmly and pull it straight up to slide it off the mounting brackets.

The panel may feel snug — a firm, even upward pull will release it.

Pull the left panel straight upward

Disconnect the wiring and air hose. With the left panel lifted, you'll see wiring connectors and a small air hose still attached underneath. Carefully unplug each connector and gently pull the air hose off its barb fitting.

Take a photo of the connector arrangement before unplugging — this helps during reassembly.

Unplug the terminal and air hose

Set the left side panel aside. Place it face-down on a soft surface to prevent scratches.

Left side panel fully removed

Steps I–K: Remove the Right Side Panel

ℹ️

The right side follows the same extract → disconnect → set aside sequence as the left.

Lift the right side panel straight upward. Grip the right side panel firmly and pull it straight up to slide it off the mounting brackets.

Pull the right panel straight upward

Disconnect the wiring and air hose. Same as the left side — unplug each connector and gently pull the air hose off its barb fitting.

Unplug the terminal and air hose

Set the right side panel aside. Place it face-down on a soft surface alongside the left panel.

Right side panel fully removed

✅

Side panel removal complete! Both panels are off. Bag and label all hardware separately from the hood screws.

Reassembly & Moving Tips

Putting it back together after your move

▼

ℹ️

Reassembly is the reverse of removal. Work backwards: side panels first, then hood.

Side Panels: Reconnect each panel's air hose and wiring connectors first, then slide each panel down onto its brackets. Reinstall all screws (10 in back, 2 on outer side, 2 at seat frame). Reattach the decorative cover flaps.

Hood: Align the hood and push it inward from both sides until it seats. Install the 4 mounting screws. Reconnect each lampshade's wiring, then twist each lampshade clockwise to lock it in.

💡

Moving Tips:
• Wrap side panels and hood in moving blankets or bubble wrap
• Transport the chair upright if possible
• Keep labeled screw bags taped to the back of the chair
• After reassembly, power on and run a quick test cycle to confirm everything works
