Folding Marker Breakaway
See Figure 9. The marker arm has a pivot at the
hinge which is connected rigid with a 5/16 inch
bolt (1). The shear bolt will break if excessive
force is put on marker during operation allowing
marker arm to swing away rather than cause
damage to the marker.
NOTE: The shear bolt is a 5/16 x 1 1/2 inch grade
5 bolt and is identified by three markings on the
head, see page 60. It must be replaced by an
equivalent grade 5 bolt to prevent marker dam-
age.

Store drill where children do not play. If possible,
store the drill inside for longer life.

et in its square bore.
