CAUTION
Possible Equipment Damage!
Avoid scratching or damaging the grooved or gland
surfaces or the ring and seals.
20. Lubricate the outer cylinder rod assembly with clean
hydraulic oil and install the rod assembly into the
cylinder barrel with a slight twisting motion.
21. Using a spanner wrench, secure the outer cylinder head
to the cylinder barrel.
Flying Parts Hazard!
Use only a source of controlled hydraulic oil pressure to
cycle or pressurize the cylinder.
Parts can fly from the cylinder at dangerous speeds when
using air pressure.
22. Pressurize and cycle the cylinder with hydraulic oil
pressure. Test pressure should be 5250 psi (36197.4
kPa) (rod side pressure) and 3500 psi (24131.6 kPa)
extended (piston side pressure). Check for proper
operation and any leakage.
