decrease valve has a short piece of hose on the barb that serves as an exhaust
muffler.
-NOTICE
DO NOT CUT ACROSS THE RIDGES ON THE BARBS. DAMAGED BARBS ARE
AREAS FOR POSSIBLE LEAKS.
4. Replace the valve, pushing the high pressure hose onto the barb on the side with
the two pressed in balls. On the increase (+) valve the second hose connects to
the machine system. On the decrease (-) valve the short notched hose or muffler
connects to the other barb.
Those machines equipped with the digital display also require plugging in the
electrical connector. On these machines it is essential that the electrical wires
have enough slack so the connector is not pulled off if the hoses must be pulled in
during installation of the valve.
-NOTICE-
USE CARE DURING INSTALLATION. DO NOT PULL THE CAP OUT ON A NEW
VALVE AS THIS WILL REMOVE THE CAP-SPOOL ASSEMBLY AND MAY DAMAGE
ONE OF THE "O" RINGS ON THE SPOOL. IF THIS OCCURS THE VALVE MAY NOT
SEAL PROPERLY.
5. Replace each increase (+) and decrease (-) cap with the (+) or (-) symbol toward
the user when in the exercise position. When in the exercise position, the increase
(+) cap should be on the right side handle.
6. Reconnect the quick disconnect to the compressed air system.
-NOTICE-
BOTH INCREASE AND DECREASE CAPS MUST BE SECURED IN PLACE. IF THE
AIR SUPPLY IS CONNECTED WITH THE CAPS REMOVED AND THE THUMB
BUTTON IS PULLED SLIGHTLY, IT IS POSSIBLE TO BLOW THE SEAL OUT OF
THE VALVE
