 1) Measure and cut off excess spindle from the wheel post, leaving
2 mm) above the wheel post. Remove burrs.
1/16 inch
m) Screw the drive cam onto spindle until snug, then back off until
the appropriate slot in the drive cam lines up with the keyway of the spindle.
Drive cam slots are labeled RH (right-hand), LH (left-hand), W (vertical-up),
and VD (vertical-down) for the four different mounting positions (reference
Figures 15 and 16).
n) Insert the spline key with the key handle pointing away from the
center of the cam. Drive the spline key in carefully. If the spline key
becomes loose, the lock will not function properly. Make certain that the
spline key is tight.
NOTE
Before screwing dial/spindle into the drive cam
for the final time, lubricate the dial, dial
ring, and drive cam bearing surfaces. Sargent
& Greenleaf recommends G-322L lubricant
manufactured by General Electric. NEVER use
oil- or petroleum-based lubricants.
The lock
o) Attach the back cover using the cover mounting screws.
is now ready to have the new combination set.
Torque Adjustment. To adjust torque, remove the back cover and
3.2.4.5
insert a 3/32-inch allen wrench into the adjusting screw (see Figure 16).
Turn clockwise to tighten or counterclockwise to loosen.
NOTE
Adjustment should not be less than 18 inch
ounces (0.13 NGm) nor more than 24 inch-ounces
(0.17 NGm) of dialing torque (a slight drag
on the dial). Whenever lock torque is changed,
the combination must be reset.
Maintenance Recommendations. Periodic servicing will extend the
3.2.4.6
life of the lock and is essential for maintaining proper security. Each time
the combination is changed, inspect the lock for wear, metal filings, drilled
holes, cracks, or any other visual signs of attempts to defeat the lock by
forced entry techniques. The inspection process should include removal of the
back cover of the lock, and visual examination of each wheel part, as well as
the cam and lever assembly, to make sure nothing is worn or damaged. If
lubrication is required, use molybdenum-disulfide (powder). NEVER use oil- or
petroleum-based lubricants on combination locks.
