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 maintenance, time and
repair.
Breakaway Protection
The marker arm is attached to the marker body with a
5/16" 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.
Marker Transporting
Always transport the marker with it folded in the flat fold
position.
Lubrication
NOTE: The breakaway bolt is a 5/16"-18 x 1 1/2"
long grade 5 (G.P. # 802-012C). It is identified as a
grade 5 by having three marks on the head. If it
breaks, it must be replaced by an equivalent grade
5 bolt to prevent marker damage.
