NOTE: If you have trouble gripping
the piston assembly, use the

to see if it is clogged with debris.
Insert a small wire to unclog hole if
needed.
8. Check the filter to see if it is
clogged with debris and gently
brush it clean.
9. Check the sealing area of the
piston and clean it if it is dirty.
10. Check the U-packing for cracks or
damage.
11. Reassemble in reverse order.
NOTE: Please be sure to push the piston all the way down. The top of the piston should sit
approximately 1-1/8" (28 mm) below the rim of the valve. Otherwise the valve cap
will not assemble properly and there is a risk of leakage.
