4. Check and replace any damaged
o-rings and seals. O-rings and seals
can be wiped clean but not soaked
in solvent.
5. Unscrew packing nuts and replace
the packing ONLY if a leak will not
stop when the nut is tightened (See
Figure 5). Do not over-tighten a
packing nut because this will restrict
movement of the needle.
6. Re-assemble in reverse order of
above and use a non-silicone oil on
moving parts. Apply Vaseline® or
light grease on threaded joints and
hose connections.
