6. APU CHAINCASE OIL LEVEL CHECK.
WARNING
APU chaincase oil is hot after operation. Make sure chaincase oil is cool before
checking oil level.
Open side APU access door. Reach around to rear of APU compartment (to your right side) and remove filler plug (9).
With finger, check that oil level at fill hole reaches to bottom of threads. If necessary, add oil to chaincase through fill hole
until oil level reaches threads (see key for required oil type). Install filler plug (9).

wipe with clean rag. Reinsert dipstick, and remove it again. Observe oil level indicated on dipstick. If oil level reads
below full (F) mark, APU crankcase oil fill cap (7) and add oil until level rises to F mark (see key for required oil type).
Install dipstick and screw it down. Hand-tighten.
