4. If the mounting screw on the right side is loosened (turned counterclockwise), the roller will move to the left. If the mounting screw on the left side is loosened (turned counterclockwise), the roller will move to the right. NEVER
LOOSEN OR TIGHTEN BOTH MOUNTING SCREWS AT
THE SAME TIME ON THE SAME UPPER ROLLER
SUPPORT.
5. If you have loosened one of the mounting screws and the roller has moved, and you need to move the roller in the opposite direction, you must tighten that mounting screw BEFORE loosening the other screw to move the roller in the opposite direction. When tightening the first screw, turn it clockwise with the torque screwdriver until the maximum torque is reached. Then loosen the other screw. AGAIN, NEVER
LOOSEN OR TIGHTEN BOTH MOUNTING SCREWS AT
THE SAME TIME ON THE SAME UPPER ROLLER
SUPPORT.

6. It is extremely important that you maintain downward pressure (towards the floor) on the head of each screw at the same time as you tighten or loosen the screws. Each screw must be completely at the bottom edge of its hole in the back of the Y-Bracket. If this is not done, the Upper Roller
Support will not be perfectly level and will not perform its function properly.
7. Following all of the information in this section precisely will ensure that the Pinch Roller Support springs are deflected and the lower tail of the springs will always be pressed against the
Pinch Roller Spacer (without a gap) as shown in Figure 3-19.
