7. Referring to Figure 2-17 , carefully
align the receiver within the traced
outline and mark the two screw
holes for drilling. Repeat for the
other side.
8. Referring to Figure 2-18 ,
detach the earcups from the pile
fasteners, and peel back the pile
fasteners.
NOTES:
• If necessary, peel the edgeroll away
in the earcup area to protect it from
the drill bit.
• It is advisable to drill pilot holes,
using a #52 (1/16") drill bit, before
drilling full-size holes.
9. Ensuring that the pile fastener
inside the helmet is not in the
drilling area, drill both the right
and the left marked hole locations
with a #25 drill bit ( Figure 2-19 .)
10. Carefully remove any frayed fibers
resulting from drilling.
(Continued on next page)
When drilling (Step 9), keep your
hands away from the drill bit to
avoid injury.
When drilling (Step 9), hold the
drill perpendicular to the helmet to
prevent damage.
