WARNING
COMPONENT RUPTURE HAZARD
Do not clean or wipe the piston valve threads. Cleaning the piston valve
threads could destroy the special sealing patch and cause the piston valve to come loose during operation, causing pump bursting and possible serious bodily injury.
Not used on 244197
Fig. 6. Unscrew piston valve from piston rod. Clean and inspect parts. The piston has a special thread locking/sealing patch. Do not remove the patch. The patch allows four disassembly/assembly procedures before it is necessary to apply Loctiter to the threads.
