Adjustment Adjustment Steps 141
CR STEEL BELT TENSION ADJUSTMENT
This adjustment is necessary for service operations that require you to remove/
loosen the CR Motor or CR Steel Belt. When replacing or re-installing the CR
Steel Belt, you need to confirm the tension of the CR Steel Belt. Tighten or
loosen the screws on the Driven Pulley to increase or decrease the tension.
Standard: 100g ± 10% (at the point where the CR Steel Belt
contacts the CR Rail)

PF BELT TENSION ADJUSTMENT

loosen the PF Motor or PF Belt. When replacing or re-installing the PF Belt,
you need to confirm the tension of the PF Belt.
Standard: 3500g ± 10%

CHECK
PO INT
After making sure the tension is 100g ± 10g, look at the
position of the Steel Belt on the Driven Pulley as you
move the carriage back and forth by hand. The Steel
Belt should be in the center of the pulley and must not
slide/drift to one side or the other. If the Belt drifts to
one side loosen the screw on that side a quarter turn
(or tighten the screw on the opposite side a quarter
turn). Test the drift again by manually moving the
carriage. When satisfied the drift is almost completely
gone, test the tension again.
