Where can i find a manual for a Perkin-Elmer 1310 Infrared Spectrophotometer?

I'm an Organic Chemistry student at Jefferson Davis Community College in Brewton, Alabama. We have a 15 year old IR Spectrophotometer, but the manuals have been lost due to possible cleaning. The machine looks in good condition and we are trying to find out if we can use it and what items we may need to get to operate it. any information would be greatly appreciated so we can use this machine for experiments needed in our cl.
