2. Make a cut and hold the buttons in. While reading the main system gauge, adjust the valve
until you have the correct pressure. Clockwise to increase, counterclockwise to decrease.
NOTE: The knife should not move until the clamp contacts the stock. If it does, you must increase
the pressure.
3. Tighten the lock nut while holding the hex wrench in place.
4. Proceed to readjust the other valves.

8.8.3 Clamp Up Sequence Valve

(See Figure 33 on page 46)
This valve maintains clamp pressure so the clamp remains down until the knife has stopped in the up
position. Factory setting: 800-1100 PSI.
Check Procedure:
1. Open the left access door of the cutter.
2. Press the cut buttons, and while reading the pressure on the main gauge (front gauge),
release them. The gauge should read between 800-1100 PSI as the clamp is going up.
There should be no clamp movement until the knife is stopped in the up position.
3. If correct, proceed to check the remaining valves.
To Adjust:
1. Remove the protective cap and loosen the lock nut on the clamp up sequence valve.
2. Make a cut and release the buttons. Read the main gauge as the clamp is returning. Adjust
the valve for a reading of 800-1100 PSI.
3. Tighten the lock nut while holding the hex wrench in place and replace the protective cap.
4. Proceed to check the other valves.
