To repair the tip end of the piston,
refer to the instructions below.

Check the piston ring for excessive
wear, breakage or deformation that
would allow it to be less that a tight fit
in the barrel. If the piston assembly is
a loose fit in the barrel, replace it.

must not be less than 5 3/8”. When
less than this length, the piston must
be replaced to avoid tool damage.
