setting is at 2600 psi.

l Check that the hydraulic filter element is not

completely full of contaminants. If the red indicator

button on the hydraulic filter body pops up, change

the filter element. See Filter Maintenance, p. 35.

l Check that the needle valve SV2 on the Spinner

hydraulic manifold is properly adjusted. If the se-

quence valve SV2 is rotated clockwise to refusal, the

spinner will not operate. Rotate the needle valve

SV2 counter-clockwise until the spinner doors close

before the spinner begins to spin. See

Drawings. p. 126.

l Check that no hissing sound comes from the Spin

button. An air hose is broken or disconnected if

there is a hissing sound. Locate the leak, and

replace the hose. See Drawings, p. 112.

l Check that the air logic manifold works. Shut

down the hydraulic power unit. Pull out all Grip

buttons. Disconnect the clear air hose from

the Spin button air valve top left port. See Draw-

ings, p. 112, 118. To disconnect the clear air hose,

push the hose and collet ring into the valve port.

While holding down the collet ring, pull out the clear

air hose. Place your hand over the disconnected air

hose. Push in the bottom or middle Grip button. A

steady blast of air should come out of the hose. If

air comes out of the clear air hose when the Grip

button is pushed in, the air logic manifold works.

Connect the clear air hose to the Spin air button.

Proceed to the next step. If no air comes out of

the clear air hose when the Grip button is pushed in,

check that the air hoses are properly connected

within the Left and Right control panels. See

Drawings, p. 110, 112. If the air hoses are properly

connected within the Left and Right control panels,

replace the air logic manifold. See Drawings, p.

110, 116.
