Service Instructions for the Penny & Giles X3000 Series Crossfader
Introduction
This section describes how to service the Penny & Giles PGFX3000 Series crossfader. Servicing is limited to cleaning, re-lubrication
and replacement of some components, such as the slider and track assembly. Periodic maintenance of these parts provides a smooth
operating feel and extends the life of the unit. Cleaning of the unit is necessary if it is used in dirty or dusty environments or if con-
taminants have reached inside. The fader must be removed from the panel before servicing.

Instructions
1. Remove the two screws from the end of the fader where the
wires exit, and pull away the end block. Withdraw the dust
cover and damping washer. Taking great care remove the
slider assembly, ensuring the wiper contacts are not damaged
as this affects operation. Cleaning of the slider assembly is
possible by gently wiping the wiper contacts and slider bear-
ings using a tissue or cotton bud. If the slider bearings are
excessively worn, as seen by excessive slider rocking, a replace-
ment assembly should be fitted.
2. Clean the guide rod, using a tissue or cloth, removing all
traces of dirt or contamination.
3. Remove the track by carefully withdrawing from the unit and
placing face up on the desk. It may be cleaned with a lint free
cloth, rubbing firmly along the track so no debris remains.
If necessary, the track can be washed in warm water, wiped
gently and then dried thoroughly using a dry cloth. When
dry, wipe with a lint free cloth and check for marks along the
track. (Note: Lint-free clothes are recommended to avoid dust
or fibers from being deposited). If the track appears worn, or
if cleaning does not improve operation, replacement may be
necessary.
4. Examine the centre channel of the fader body and if dirty,
clean using cotton buds.
5. Re-assemble and lubricate the fader as follows:
a) Hold the fader body so the end block is to your right, as
shown below (the label may be on either side).
a) Insert the slider assembly onto the guide rod and into the
fader body, with the contacts facing away from you.
b) Insert the track into the back of the fader body with the
track contacts facing you (to meet the slider contacts).
c) Lubricate the guide rod by placing one small drop of silicon
oil, using a cocktail stick, either side of the slider assembly.
Move the slider from end to end in order to disperse the oil
evenly. Carefully wipe away any excess oil using a tissue or
cloth.
e) Insert the dust cover and damping washer. Hold in place
while securing the remaining end block. Be sure track wires
exit the bottom of the fader body and are not pinched.
6. Once assembled, move the slider from end to end and ensure
operation is smooth.
