4.2.5 Installation of belt pulley and V-belt
When leaving the factory, the belt pulley and V-belt of extruder have been installed and
adjusted in their desired position. However, the fixing bolts may be loosened during
transportation and installation, which will cause the offset of the belt pulley. Therefore, it is
necessary to re-install or re-adjust the belt pulley, and the V-belt after the extruder is well
installed on the desired position.
