WARNING
If the compressed air, high-pressure water, or steam hits your body directly or dirt is scattered by use of
it, there is a danger of personal injury. Wear the protective equipment such as the protective eyeglasses
and dust mask.
NOTICE
When using the compressed air, blow it from some distance to avoid damaging the fins. Damage on the
fins can cause water leakage and overheating. Especially when blowing the compressed air against the
