John,
I attended my Rotax maintenance course at Lockwood Aviation in Sebring Florida.
They are the largest Rotax maintenance shop in North America. My course was
given by Mr. Dean Vogel who has been doing this course for Lockwood for a long
time. He specifically instructed the attendees that the Rotax 9xx engine should
be properly checked for oil level prior to the first flight of the day and
subsequently any time that day that the aircraft had been parked for a while.
He said that the engine oil should be check according to Rotax Service
Instruction
SI-27-1997. You can go to Rotax-Owner.com (The Factory Authorized Website
for Information, Education & Support), go to "Information" tab and select
"All Videos" to get a list of all their instructional and educational video.
They have an excellent video on performing a proper oil level check, complete
with 'burp' in accordance with SI-27-1997. Also under the "Instructions" tab
is a section "Service Bulletins" where you can gain access to all SBs, SIs and
SL.
Excuse me while I get out my Soap Box:
If any Europaphiles out there are flying behind a Rotax 9xx engine and you are
not signed up at Rotax.com, shame on you. It is the PRIMO location for current
information on the Rotax engine. They also provide e-mail updates and
notifications
on new and updated procedures and videos. Ya, it's gonna cost you a
couple bucks (or pounds or euros) but it's worth it.
OK, down off my Soap Box...

advice is - do not hand crank unless there is a good reason to do so.
