Performer Tubing

Identifying A-dec Tubing

Using Suggested Fittings

Identifying Detail

This section identifies the tubing type used when servicing A-dec products. Allow adequate length when installing to avoid crimping or bending of tubing. The use of the appropriate tools can improve the ease of tubing installation or replacement.

Unit-clamps or tubing sleeves must be used to ensure a good seal and to prevent tubing from coming off barbs.

For 1/4" polyurethane tubing, use 1/4" barbs with sleeves and 1/4" Poly-Flo fittings.

For 3/8" Polyurethane tubing, use 3/8" Poly-Flo fittings.

When identifying tubing, the body color of the tubing is the “tubing color”. The line and/or the A-dec name printed on the tubing are the “tracer markings”. These two details will identify the type of tubing you will need and its use.

Removing a Solenoid

Installing a Solenoid

To remove a solenoid:

1 Lower the chair base and back to the full down position to depressurize the

hydraulic system. Remove the motor pump cover, then unplug the chair.

2 If necessary, remove the two mounting screws that secure the manifold

to the hydraulic tray. Rotate that manifold so the solenoids are accessible.

3Using a flat blade screwdriver and a 9/16" wrench, remove

the defective solenoid.

4 Cut the defective solenoid wires 3" (74mm) from the coil

and discard.

5Remove the old o-ring from the solenoid cavity and clean

out any excess oil. Replace the o-ring with the correct o-ring provided in the kit.

WARNING

The solenoid coils are powered by line voltage (100, 120, or 240V AC). Failure to unplug the chair may result in serious injury from electrical shock.

The following steps will guide you through the procedure for installing a solenoid.

85.0812.00, 2003 PR-27

Performer Hydraulic Manifold

Replacing a Solenoid

To replace a solenoid:

1 Install the new solenoid stem and poppet into the manifold and tighten to 35-40 in lb

(.11985–.2284 Nm). Position the remaining solenoid parts on the stem and secure by tightening the retaining nut to 25-30 in lb (.14275–.1713 Nm).

2 Cut the solenoid wires 3" (75 mm) from the coil. Install the stripped wires from the

solenoid and the connector housing into a wire nut. Repeat for the remaining wire.

3Using the mounting screws, secure the manifold to the hydraulic tray.

4. Plug in the chair. Test the chair functions to ensure proper operation and that no fluid leakage occurs. Reinstall the motor pump cover.

85.0812.00, 2003 PR-28

Performer Troubleshooting

Task Description

1 Remove the motor/pump cover from the chair.

2 Fit a 5/8" wrench to the high pressure outlet port

(either lift or tilt, whichever is in hydrostatic lock) of the hydraulic manifold. Hold the port still and use a 9/16" wrench to loosen the hose fitting.

3 Place a shop rag around the fitting to absorb

the fluid.

4 Carefully loosen the fitting counterclockwise until

oil begins to leak from the fitting. Retighten the fitting. Operate the down function. A second release of hydraulic fluid may be required.

5 Adjust the limit switch that caused the hydrostatic

lock (refer to Adjusting the Base Up Limit Switch). In some cases it may be necessary to remove and replace the limit switch. Adjust the new limit switch as needed. Also ensure that the large gear/actuator is securely installed and not slipping.

6Cycle the chair a couple of times to verify it is no

longer in hydrostatic lock.

Tilt cylinder high pressure fitting

Lift cylinder high pressure fitting

Correcting Hydrostatic Lock

Hydraulic lock occurs based on the following conditions:

•chair base or back is stuck in full up position

• limit switch not activated, or

• down solenoid poppet is unable to open based on excess hydraulic pressure.

Loosen the knob on the back of the headrest. Move the headrest into the desired position. Tighten the headrest knob.

The headrest should move freely while positioning yet maintain its position when set. Turn the tension adjustment screw clockwise to increase friction and hold the headrest more securely. Turn the tension adjustment screw counterclockwise to decrease friction and allow the headrest to move up and down more freely.

Audible leakage when foot control is not being used

Do these steps in the order listed, until the leakage has stopped.

Task Descriptions

1 Check mounting screws in the bottom of the baseplate to make sure they are tight.

• If leakage has stopped, test unit.

• If there is still audible leakage, continue with step 2.

2Remove the cover and check the internal tubings for secure connections.

3 Check for leakage from the exhaust holes on the signal relay valve. If there is leakage, do

the following

•move the master On/Off toggle to the OFF position and bleed the system of air pressure

• inspect the stem and o-rings for debris or defects, and

•inspect the seat for debris or defects.

4Replace any defective parts. Lubricate the o-rings, reassemble and test the foot control.

5 Check for leakage around the diaphragm. If there is leakage, do the following:

•Tighten the two screws securing the signal relay valve to the foot control valve. If there’s still leakage, replace the diaphragm.

Troubleshooting Foot Controls

Tips and troubleshooting information are listed in the following charts to assist in diagnosing foot control problems. These charts do not cover every situation, but do try to include the most common problems you may encounter. In most cases, it is recommended rebuilding the whole foot control using the appropriate service kit. This normally solves the problem and saves time.
