electronIcS
If the piano is not producing any sound check that it is properly plugged into an appropriate outlet, ensure
that the grounded cable is not defective, and with the piano unplugged from an outlet, check the piano’s
internal line fuse for a fault.
If the piano has power, but isn’t producing sound, plug a 1/4” cable from the oUT (Send) JACK to your
amplifier. If the piano can be heard through the amplifier, there may be an electronics issue or faulty con-
nection. Check that any 1/4” cables being plugged into the piano are functional and properly inserted.
Remove any effects pedals from the signal chain to ensure they are not at fault. Check that the RCA cable
connecting the harp to the jackboard (Active Model) or name rail (Passive Model) is firmly seated in the
RCA jack. Check that the harp is not at fault by plugging a 1/4” cable with RCA adapter between the harp
and an amplifier. If the piano can be heard through the amplifier, the harp is not the issue.
StIckIng keyS
If a key becomes sluggish or remains in a depressed position, one or more of the key bushings may have
swelled due to changing atmospheric conditions. First, check for left to right movement of the offending key.
A very slight amount of side-to-side movement should be present. If the front of the key feels tight, rock the
key back and forth over the key pin to free it.
If the key still sticks, the pin hole or balance rail bushings may be at fault, or the front key bushing may need
further spreading. Disconnect the piano from AC and all amplification. Remove the lid. On active models,
disconnect all jacks connecting the pre-amp to the jack plate. Remove two screws to unfasten the name rail
assembly and lift it out of the piano.
Lift the offending key out of the piano. Use a wedge such as a flat head screwdriver to spread the key bush-
ings located under the key front, and on top of the key at the balance point. Do not twist the wedge, as split-
ting of the key may result. Use an awl to slightly spread the balance rail pin hole on the underside of the key.
Lift the hammer assembly to replace the key in the piano.
A key is properly eased when it falls to the depressed position upon lifting the hammer upwards.

If some notes still sustain, it may be necessary to re-adjust the damper arm of the offending notes. First,
check that all action components (key, hammer, and damper arm) are returning to a proper “at rest” posi-
tion upon key release. Remove the three screws that fasten the harp to the support blocks and lift the harp
to the upright position. The damper arm is adjusted by slightly bending the arm just ahead of the bridle strap
(Fig. 4). If the damper displays insufficient tension to damp the note, or excess slack in the bridle strap,
remove the damper arm from the action rail and add a slight reverse bend to the arm (Fig. 5).
SuStaIn pedal MakeS “noISe”
It must first be understood that depressing the Sustain Pedal on an electro-mechanical instrument will
generate some amount of noise. In this case, a sympathetic vibration is produced as all of the dampers are
suddenly removed from the tines. If additional noises are encountered…
1. Check that both Sustain Bar Hinge Pins are correctly seated in their Plastic Bushings located in
the Harp Supports.
2. Check that all Hinge Pin Mounting Screws are properly tightened.
3. Check that all Bridle Straps appear straight and tight.
note : on Seventy-Three note models, it may be necessary to periodically check the relation of the Damper
Bar and the Center Pin. At rest, the Center Pin should make solid contact with the Damper Bar WITHoUT
pushing any of the damper arms down. To check Center Pin tension, unscrew the three Harp Mounting
Screws and raise the Harp.

See Sustain Pedal Installation. If problem persists with Sustain Pedal removed:
Remove piano lid. With Sustain Bar Arm raised by hand (thus disengaging dampers from tines), check that
Sustain Plunger moves freely through the Nylon Bushing. It may be necessary to loosen one of the two Strap
Screws slightly to ensure proper bind-free movement of the Plunger (Fig. 3)
