NOTICE
To reduce the possibility of costly damage to
displacement rod (1) and lower cylinder (11), first
place lower cylinder on a soft block of wood. Always
use a rubber mallet or an arbor press to drive the
displacement rod out of the lower cylinder. Never use
a hammer to drive the rod out. Damage to the rod
end will shorten pump life.
