I don't have that machine, but oiling for old machines is very similar.
There is a cover on the left hand side that can usually be flipped open. If it doesn't have a hinge, then there will be 2 or 3 screws that need to be undone so you can lift the cover off.
You also need to take the cover off the top of the machine. Usually there are 2 to 4 inset screws that you need to undo in order to lift the cover off.
Basically you put 1 drop of oil every place two pieces might rub together. Slowing moving the wheel on the right towards you helps you see where those places might be. There will also be a couple of holes for oil.
Take out the bobbin, and look for moving parts that need a drop of oil.
I always keep a couple of plastic lids nearby to hold screws so I don't lose them. When you open the top, do not oil the gears; they will usually have some white or brown grease on them. Just leave the grease (or you can get a tube of Singer lubricant for greasing the gears).
It's easy to over-oil. Keep a scrap of cotton batting underneath the presser foot to catch any oil leaking down. I thread the machine and run it after oiling, until the thread both top and bottom sews clean. Usually I let the machine sit overnight and do this again to make sure no more oil is going to get on the thread.
