Glad to see it worked out. Note mine has a plastic cowl on it, to enhance cooling.
The head Rarely seems to go past pretty warm, (say on a Fill from empty two times in a row) definitely not hot, Although not run extensively.
HINT: My compressor handbook said to torque the head down before the first run, and then after a short time re-torque it before extensive use.
Note it also said failure to do this, invalidates the warranty!
puzzled by this, surely the Factory torgue them up?, and why a second time?
As it was, mine were all spot on; with only one needing a 3 degree extra turn to hit 27 Nm.
Expansion and contraction that's why.
