Section VIII: Keyboard Maintenance

Occasionally it will become necessary to clean and adjust the keyboard. The contacts, although

gold plated, may become dirty, contaminated, or corroded. When contacts become poor, noises

and erratic sounds may be generated while playing the instrument.

To service the keyboard, the bottom cover must be removed. This cover is held on with 8 wood

screws. If the keyboard compartment is found to be excessively dirty, it should be blown out

with air first.

Avoid touching the buss bars or the spring contacts with the fingers since hand oils and

perspiration will cause corrosion. Under normal conditions, any dirt can be removed by spraying

the assembly with a light coating of a high grade contact cleaner. At the factory, we use and

recommend Cramolin®. If this is not available, TV tuner spray may be used. Do not under any

circumstances use abrasives or abrasive tools, since this will destroy the gold plating. If spraying

does not cure the problem, try wiping the buss bar with a cotton swab in the area of the problem

key or keys.

Sometimes it is necessary to adjust the spring contacts for more tension. This is done by bending

the spring so that it is closer to the buss bar. It is easiest to bend at the end nearest the mounting

board. In all cases, the "pitch" contact must occur before the "trigger" contact. The pitch buss

bar is nearest the front of the instrument. The trigger buss bar is in the center, and the third buss

bar nearest the rear of the instrument is not used and therefore need not be cleaned or adjusted.

To clean the keys, use a soft cloth moistened with a mild soap solution. Never allow solutions or

spray cleaners to run down between the keys. Avoid harsh solvents, since the keys are made of

plastic and may be dissolved. Scratches may be removed with a plastic or automotive polishing

compound. Waxing the keys is not recommended.
