1.
Check the packing nutlwet-cup daily. First follow
the Pressure Relief Procedure Warning on page
2.
Be
sure the wet-cup is
113
full
of TSL.at all
times to help prevent fluid buildup on the piston
rod and premature wear of packings. The packing
nut should be tight enough
to
stop leakage, but
no tighter. Over tightening may cause binding and
excessive packing wear.
Use
a round punch or
brass rod and light hammer to'adjust the nut.
