b) Using the template (provided with lock), drill the six 8470
deadbolt base-attaching screw holes (0.149-inch (4-mm) diameter for self
tapping screws). Drill the hole for the spindle shaft (0.813-inch (21-mm)
diameter if lock has a tube, 0.625-inch (16-mm) diameter if lock does not).
c) Securely fasten the 8470 deadbolt base and drill resistant hard
plate to the door by tightening the screws.
If not, go to step i).
If the lock has a tube proceed with step d) below.
d) Remove the back cover of the lock.
e) Place the lock bolt in the locked or engaged position and the
accelerator spring in the loaded position. (Figure 11 - Note: Do not remove
the drive cam.)
f) Insert tube and hold lock against the 8470 deadbolt base.
dial ring on tube and lightly tighten tube nut.
g) Measure and mark tube excess from door. Remove the lock and add
3.0 millimeters or 1/8 inch (to insert the dial ring bushing) and cut off
h) Remove any burrs from the end of the tube.
i) Securely fasten the lock to deadbolt base with four attaching
screws and tighten.
j) Fasten dial ring to door using screws and tighten tube nut (if
present on lock) and align with hole through door.
k) To install dial, hold the drive cam in place with one hand and
thread the dial into the cam until the dial comes to a stop against the
surface of the dial ring.
When threading dial into cam, do not allow
cam to slide outward against the accelerator
spring. Accelerator spring can be easily
damaged in this manner.
1) The alignment of the dial and dial ring is critical to the
operation of the lock. Perfect alignment is necessary. The dial should be
flush and centered with the surface of the dial ring for true center.
Measure the excess spindle that projects beyond the drive cam,
Remove the dial, cut off excess spindle and remove burrs.
