4. At the off-load end of the oven, thread the XCS chain through the sprockets. Reconnect the master link.
Make sure the closed end of the keeper clip is facing the direction of conveyor travel.
5. Check that the XCS chain is properly engaged with all of the sprockets and is not hung up or twisted
anywhere on top or underneath the oven.
SET XCS TENSION
Caution: Excessive tension in the XCS system will accelerate wear of the XCS chain.
1. Run the conveyor through several revolutions to ensure the XCS chain is properly settled.
2. The XCS tension is adjusted at the onload end of the machine by moving the XCS drop arm. The arm is
fixed by a slotted link. Use a 5/32 hex key and loosen the clamp screw to reposition the arm.

3. Adjust the XCS onload drop arm so that the lowest point of the XCS return loop is 2 to 3 inches (50 to
75mm) from touching at its lowest point.
SET XCS TIMING
Note: After extended service the XCS and edge rail chains may wear at different rates and this can affect their
pitch match. It may not be possible to park the XCS between the edge rail pins if excessive mismatch develops.
It is always better to set the XCS park position outside the edge rail pins if possible.
1. Position the XCS rail just outside of the fixed edge rail chain pins.
2. Examine the position of the XCS plates relative to the edge rail pins. Adjust the XCS timing to equalize
the available clearance between the tip of the XCS plates and edge rail pins as the XCS plates sweep in
and out of position at either end of the machine.

3. Make coarse (3/8 ) timing adjustments by moving the XCS chain ahead or back one tooth at a time on the
drive sprocket at the offload end of the machine.
4. Fine adjust the timing (within the last 3/8 ) by indexing the slotted drive sprocket on its hub.
5. Operate the conveyor and watch the interaction of the XCS plates and fixed rail pins through several
revolutions of the chain loops before moving the XCS into park position.
