Note: When all the fittings and hoses are routed and
hooked up the system will need purged of air. The
system will need purged before the rod end of cyl-
inders are hooked up as cylinders will not extend
fully if hooked up. Be sure rod end of cylinders
and
are un-pinned and wood blocks are put
under cylinder to allow rod ends of cylinders to
fully extend without hitting anything on machine.

dles) until cylinders are fully extended. Fully retract
and extend the cylinders several times to purge air of

essary.

hooked up with the 1 x 3 1/8 pins , 1.5 x 1.0 x
0.075 machine washer and 3/16 x 2 cotter pin. Bend
cotter pin to secure.
