Maintenance
Proper servicing and adjustment is the key to the
long life of any farm implement. With careful and
systematic inspection, you can avoid costly main-
tenance, time and repair.
Breakaway Protection
The marker arm is attached to the marker body
with a 3/8" breakaway bolt. If excessive force is
put on the marker during operation, the bolt will
break, allowing the marker arm to swing away
rather than cause damage to the marker.
NOTE: The breakaway bolt is a 3/8"-16 x 2" long
grade 2 (G.P. # 802-266C). It is identified as a
grade 2 by having no marks on the head. If it
breaks, it must be replaced by an equivalent
grade 2 bolt to prevent marker damage.
Marker Transporting
Always transport the marker with it folded in the
flat fold position.
