While pressing the FHL firmly onto the airframe so that it does not move,
insert the E-Drill completely into the FHL. Concentricity and
perpendicularityis critical to eliminating airframe damage; if in doubt
remove the E-Drill, check and adjust the FHL and re-insert the E-Drill.
Adaptor into FHL Concentric E-Drill Alignment
CAUTION
When using the CG Hand Tool, failure to establish electrical ground with the E-
Drill Ground Pin and the fastener head will result in a failed cut cycle. Re-clean the
fastener head and attempt to reestablish a proper system ground between the E-
Drill Grounding Pin and the fastener head. Avoid, striking, grinding, or scraping
the E-Drill Ground Pin on the fastener head. Abuse will result in damage and
misalignment of the E-Drill Ground Pin and system failure.
D)
Squeeze the trigger until cutting sequence is completed, as with the button-
head fastener removal.
E)
Upon completion of the cut remove the FHL, select a proper size hand punch
and center the punch in the cut. Sever the fastener head with a sharp blow on
the punch with a hammer. It may be necessary to strike the punch more than
once. If the fastener head does not separate, the fastener is most likely an
oversize stem. Select an oversize cutting electrode and setting. Reapply the
FHL and re-cut the fastener. Attempt to sever the fastener head again with a
punch and hammer.
