1. For angle nailing, you'll probably want to remove the rubber "boot"
from the saftey tip and set the drive depth to maximum.

2. I have the same compressor, and mine leaked badly where the pipe
nipple that supports the pressure switch is threaded into the tank.
This is a weak point in the design, since any tension on the air hose
stresses the threaded connection, and in my case, the joint was barely
finger tight. After disconnecting the electricals, I was easily able to
tighten it another full turn by hand. Chalk that up to shoddy assembly
(regarding the comment on Chiawanese tools, my compressor was labled as
assembled in the USA).

3. I leave my compressor filled. Now that I've fixed the leak, it holds
pressure indefinitely, so I can shoot off a few nails when I need them
without the unbearable racket of the compresor running. I do bleed off
the water occasionally, but a compressor tank is alwasy going to have
some mositure in it, whehter you keep it filled or empty
