I'm certainly no expert on sergers but have been told that they need a lot  
more oil than normal machines. If a thorough  cleaning and oiling doesn't  
bring any positive results - either ask/ping Ron in here or contact your  
local sewing machine specialist. OK, I'm a bit eager with my advice, hope  
you won't be offended.

It is impossible to diagnose a machine not in hand.  Some things to check.  
Is it threaded properly, yes I know but use the manual and do it again. Is  
the presser foot down? Look at the needle plate and see if the fingers are  
broken or bent, or any needle damage to the plate.
Oiling it or any machine for that matter will not solve any sewing related  
issues.
Beyond that it is advisable to have your local repair person look it over.

I'd start with a meticulous cleaning -- flossing the tension disks, evicting all the  
dust bunnies, double and triple checking the needles, etc. Check the blade, too, for
sharpness (lay a single piece of serger thread across the blade, use the handwheel  
to lower the upper blade.  If the thread scoots, the blade isn't as sharp as if it's  
cut cleanly, and might be part of your issue. Sometimes blades build up a coating
and can be "sharpened" by wiping them with a bit of cotton cloth saturated with
rubbing alcohol or unflavored vodka.  Sometimes you need a new blade or two.
Sometimes you just need to adjust the blade clearance.

  Then a meticulous re-threading, manual in hand, reading each step out loud before
you do it.  For some reason, reading out loud seems to slow down the brain enough
for the fingers to catch up.  

Then try a swatch of fabric you've serged successfully before, if the problem  
continues with the current fabric.

In my experience, timing problems result in skipped stitches or no stitches forming,
not the jams you're mentioning.
