You can expect optimum performance and extended
track life from your commercial cleaner if the
cleaner’s Drive Tracks remain tight. Bushing # 3627
is used to keep the Drive Tracks at its proper
tension. The Bushing has a eccentric hole.
Depending on what direction the bushing is installed
into the side plate, the Drive Tracks can be made to
fit looser or tighter (fig 2.).
Locate the small arrow molded into the Bushing (fig
1.) When installing the Bushing, if the arrow is
pointed towards the center of the machine the Drive
Track will be made tighter. If the arrow is pointed
away from the machines center the Drive Tracks will
be looser.
