Does anyone know where I could find a user manual for this dinosaur? This house was built in 1968 and I'm pretty sure it's original to the house. There's a plate that says I should oil every 6 months, if oilers are provided. Where do I look for "oilers?"

There would be two white or yellow caps on motor if it were the original motor. After that much time they may be missing or a different color altogether. It would be on the end of the motor. Also if it’s belt drive there might be bearings on each end of the shaft that need oiling. I’m not familiar with the furnace. Not too many that are before my time but the principal is the same. If you’ve never had the furnace looked at it would be worth a service call to have someone check the furnace out. There may be nothing wrong, but those old furnaces can have some serious issues and they are lacking safety devices to protect you like the current furnaces would
