Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank´s for your help, I already recived these manual from you

CARING FOR YOUR DRYER
CLEANING THE DRYER INTERIOR
Garments which contain unstable dyes, such as denim blue jeans or brightly colored cotton items, may discolor the dryer interior. These stains are not harmful to your dryer and will not stain future loads of clothes. It is helpful to dry unstable dye items inside out to prevent dye transfer. To clean dryer drum: 1. Make a paste with powdered laundry detergent and very warm water. 2. Apply paste to a soft cloth. OR Apply a liquid, non-flammable household cleaner to the stained area and rub with a soft cloth until all excess dye is removed.
wWARNING
Explosion Hazard Use nonflammable cleaner. Failure to do so can result in death, explosion, or fire.
3. Wipe drum thoroughly with a damp cloth. 4. Tumble a load of clean cloths or towels to
dry drum.
REMOVING ACCUMULATED LINT FROM INSIDE THE DRYER CABINET
Lint can gather inside the dryer and be a fuel for fire. Lint should be removed every 2 years, or more often, depending on dryer usage. Cleaning should be done by a qualified person.
