SAFETY PRECAUTIONS

DANGER:

Improper use of grounding plug can result in a risk of electric
shock.

DANGER:

Unplug power cord before any cleaning operation is started.

WARNING:

Gas under pressure should not be used for supply as a haz-
ardous bursting condition could develop in the pump head.
Use only gases contained at atmospheric pressure.

CAUTION:

Do not operate pump when pressure ports of both heads are
in a blocked condition.

CAUTION:

Do not use metal fittings with any Air Cadet Pump.
