A key’s deep cuts and sharp angles
make it easy to crack if forced or twist-
ed before it’s fully inserted into the
cylinder. If the key doesn’t go in or turn
easily, clean and lube the lock as above.
Use the control key only to service or
replace a cylinder.
Check the keys every time you use
them. When you see cracks in a key,
stop using it and start using your spare
operator key until you can get a new one
made.
Call the Defense Locking Sys-
tems, at DSN 482-1354/(812) 854-1354,
for assistance on ordering new keys.

Lube the shackle, steel ball and cam
with a
small amount
of molybdenum
disulfide grease. Using too much grease
or lubricant can gum up the works.
If you use the molybdenum disulfide
powder (graphite) to lubricate the key-
way and cylinder, lube it this way:
1.
Dip the key in the can of lubricant.
Remove excess lube by lightly tapping
the key against the interior rim of the
can.
If you use a corrosion preventive
compound lubricant on the cylinder,
don’t use
graphite at the same time.
This, too, can really gum up the lock
cylinder’s internal components.
2.
Insert and remove the key several
times, turning the key from LOCK to
UNLOCK each time.
Avoid using petroleum-based prod-
ucts like Lock-Eze or WD-40 on the
lock. They are big collectors of dust,
sand and other elements that get into the
lock cylinder.
1.
Place the key cap over the end of
the cylinder.
3.
Insert the control key and rotate it
1/4
turn counterclockwise.
Don’t
re-
move the key from the lock.
4.
Place the cam on top of the cylinder.
5.
Slide the upper case assembly back
into the lower case.
6.
Rotate the shackle back and insert
it into the shackle hole.
7.
Turn the key 1/4 turn clockwise.
8.
Remove the key.
Put the Lock Back Together
If you’ve disassembled, cleaned and reassembled the HSP, and the cylinder
doesn’t work, order a new cylinder with NSN 5340-01-323-1087. Order it on a DD
1348-6 from SOS S9I and note “NSN not on AMDF” in the REMARKS block.
Won’t Work?
A good way to remember which keys
match which cylinder is to mark the seri-
al number of the keys on the matching
cylinder. Use a fine-point permanent
marker.
Never etch
the
number
on the
cylinder, or you’ll damage its Teflon
coating.
Mark key number on
cylinder - don’t etch
Don’t
use
keys with
cracks
in ‘em
Insert cap and cylinder into
lower case and press down
on the cylinder
2.
Sargent and Greenleaf (S&G) Model 833C, NSN 5340-01-217-5068, has
replaced High Shear Model LK-1200 and S&G Model 831B. When the older mod-
els become unserviceable, replace them with 833Cs.
Each padlock has its own matched set of serial-numbered keys–-a control key
(with a square bow) for servicing or replacing a cylinder and two operator keys
(with a round bow) for day-to-day operation.
