Replacing Keys - Kurzweil sp5-8 Service Manual

6. Remove the key.
Caution: Each key has a key spring (silver springs for natural keys and black springs for
sharp keys). The key spring slips over a post on the keyboard chassis and is held in place
when the key is installed. When you remove a key, the key spring is free. Leave the spring in
its position on the keyboard chassis or set it safely aside.

Replacing Keys

1. Verify the placement of the key spring on the keyboard chassis.
2. If you are replacing a natural key, hook the front end of the key under the keyboard
chassis. For a sharp key, hook the front end through the keyboard chassis.
3. Lower the key into position. Make certain the key post is correctly positioned in the key
spring.
4. Align the pivot with the hole at the rear of the key. Apply pressure to the back of the key.
The key clips separate and clip on the pivot.
