6.4 Side Broom(s)
The following sections deal with adjustments and
replacement of mechanical portions of the side broom.
Adjusting the Side Broom Extension Spring
The function of the side broom extension spring is to
counteract the GEO air cylinder. As the geo switch is
activated in the extend position, the air pressure is
increased and pulls the extension spring longer. Before
adjusting the tension spring be sure the pressure to the
GEO cylinder is raising and lowering correctly with the
GEO control. Proper spring tension allows full geo extend
and retract.
