Throat Packing Adjustment
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection, splashed fluid
and moving parts, follow the Pressure
Relief Procedure whenever sprayer is
stopped and before sprayer is cleaned or
checked, and before equipment is
serviced.
When pump packings begin to leak after
much use, perform
Procedure, page 5 and tighten packing nut
down until leakage stops or lessens. This
allows approximately
additional operation before a repacking is
required. Packing nut can be tightened
without o-ring removal.
