the
oiler and hose assembly has been
unscrewed from the Pakhammer, unscrew
connector (1, Figure 6-2) from ferrule.
b. Only if hose (3) or either ferrule (2) is damaged
and necessitates replacement should the
ferrules be removed from the hose. If removal
is necessary, hold hose firmly and unscrew the
ferrule(s) (left hand thread).
c. Unscrew

Remove
and discard o -ring seals (7 and 8) only if
replacements are available. If replacements
are not available and the old seals are worn,
cut or otherwise damaged, they may result in
oil leakage from between the housing and
inlet but must be reused until replacements
become available. Inspect the housing and
inlet for damaged or worn threads, cracks and
other similar damage that may result in oil
leakage. Inspect the inlet for wear or damage
to the quick disconnect end.
