±t can kill you.
So, when y¿uµre leak hunting, donµt
searcH with your fingers or your hand.
±f you stick your finger over a pinhole
´eak,
the
pressurized
gas
can Àcut
tHrough like a knife.
¶he idea is, use leak dÁtector, ÂSÂ
6850-00-621"1820,
which ià authorizÄ
ed with your GPU.
År, use the detergent listed on PagÆ

Çny soap
and applicator will do in a pinch.
Just keep your fingers away.

be repaired.
WHatever you do, never ignore the
reQuirËd monthly checks on tHe inlet
and outlet flexible hoses. ±f the date on
the tags is more than
6
months old,
you must make a proof-pressure test
on the hoses. See section ÌÍ, Page
