General Maintenance
1.
After using your Stand Up Markers for several
hours, check all bolts to be sure they are tight.
2.
Replace any worn, damaged or illegible safety de-
cals by obtaining new decals from your Great
Plains Dealer.
Breakaway Protection
The marker arm is attached to the marker body with a
3/8" shear bolt. If excessive force is put on the marker
during operation, the shear 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 1 3/4" long -
grade 2 (G.P. # 802-253C). It is identified as a grade 2 by
having no marks on the head. If it breaks, it must be re-
placed by an equivalent grade 2 bolt to prevent marker
damage.

structions.

Hinges
The marker body hinge pivots require greasing every 20-
25 hours of operation. Each marker has two grease fit-
tings located at the center of each end of the first sec-
tion.

2-3 Years
Disk Bearings
The tapered roller bearings in the disk hub are lubricated
at the factory. Under normal conditions, the bearings
need to be repacked every 2 to 3 years. If the grease
seal or grease cap becomes damaged or is missing, the
hub should be disassembled, cleaned and bearings re-
packed. A new seal or grease cap should be installed.
