Check all screws and fasteners for proper tightening torque
BEFORE operating the unit. (See Table 5). Overtighten-
ing tightening can cause the screws and fasteners to fail.
Under-tightening can reduce the performance of the Tension
Control Clutch.
For optimum clutch action, connect the controls as close to
the unit as possible. Nexen recommends the installation of
an air line filter in the air line ahead of the controls.
For automatic tension control, use Nexen’s Electronic
Tension Control System. Contact your local Nexen Web
Handling distributor or representative for information con-
cerning this product.
Inspect all cap screws and set screws on a regular basis and make sure they are tightened to the recommended torque.
Inspect the friction facings regularly and replace them when worn to approximately 5/32" [4 mm] thick.
