consequential damages such as loss of profit, or expense, whether based on tort or contract.
This warranty is void if the articles covered by the warranty have not been properly installed,
maintained and used.
NOTE
The Air Hydraulic Press has been carefully and accurately built to give long, trouble-free service if
properly installed and maintained. Follow carefully the instructions, making sure no dirt or foreign
materials are allowed to get into the cylinder or other working parts. If you have any unusual
problems regarding controls or tooling, notify AIR-HYDRAULICS, INC., JACKSON, MICHIGAN,
at 1-800-837-4355 and our Engineering Department will be glad to assist you.
PRESS INSTALLATION INSTRUCTIONS
Install incoming air supply (100 P.S.I.) through an approved safety lockout valve which is upstream of
FRL unit. The FRL unit consists of a filter, pressure regulating valve, and an air lubricator connected
in proper order with arrows indicating the direction of air flow. It should be installed in the air line in
a horizontal position as close to the press as possible with the pressure gauge visible from the
operating position in front of the press. Connect outlet lubricator to inlet on press (tagged “air inlet”).
Turn on air and make sure there are no air leaks. Operate press and verify lubricator is allowing an
occasional drop of oil to pass into the air line (Note: the lubricator adjusted at the factory & should not
require adjustment). If required, see Preventative Maintenance section for adjusting & adding oil to
lubricator.
Caution: Do not use over 100 P.S.I. air pressure.
C-Series Press & Booster System Explained
The C-Series Press & Booster System uses a closed hydraulic system. The important thing to
remember is there is air on the bottom (rod) side of the working ram cylinder & oil on the top
(opposite) side. Secondly, the booster unit is a stacked cylinder assembly. The top cylinder is
an intensifier or multiplier, having oil and the lower section of the booster assembly having
air on both sides of the piston. A series of seals between the upper and lower cylinder sections
separate and isolate the air from oil. An oil reservoir is used to assure the closed hydraulic
circuit is free of air and always full of oil. Lastly, the air that returns the ram cylinder also
returns or retracts the booster cylinder piston simultaneously to the home position allowing
the oil to return to the top side of the booster cylinder assembly.
