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.

CAUTION

Do not remove retaining screw from the manifold.
Do not completely close a speed control valve. The
motor/pump could overheat and become damaged
from pumping against a closed valve.

Retaining
screws

To adjust... Do this...

Base up speed Turn base up control valve:

clockwise to decrease speed, or
counterclockwise to increase speed.

Base down speed Turn base down control valve:

clockwise to decrease speed,
or counterclockwise to increase speed

Back up speed Turn back up control valve counterclockwise to decrease

speed, or clockwise to increase speed. Back down speed.
Turn the back down control valve, clockwise to decrease
speed, or counterclockwise to increase speed.

The hydraulic manifold incorporates four speed control valves which restrict or divert the flow of
hydraulic fluid to and from the lift and tilt cylinders.

NOTE: The speed control valves are hex drive.

NOTE: This is opposite of the other three control valves.

Turning the back up valve counterclockwise too
far may disable this function.

Performer Hydraulic Manifold

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.

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.
