ADJUSTMENT & OPERATION PROCEDURE
1. To insert the correct shell holder head in the Cam-Lock

Trimmer, turn shell lock
counterclockwise until the spindle is clear of shell holder head slot and insert correct
shell holder head. Return shell lock to its original position.
2. To insert pilot, loosen set screw in cutter and insert the correct size of pilot for your
case neck. Retighten the set screw.
3. To adjust the trimmer to the desired length, pull the handle out until stopped by the
cutter. Loosen the spindle lock knob about 1 turn. You may need to push in on the
spindle lock knob to release the spindle. Slide the spindle back to make room for the
case. Turn the shell lock counterclockwise until a case will fit in the shell holder. Move
the cutter to the full in position. Move the spindle inward to start the pilot in the case
mouth. Lock the case in place by turning the shell lock clockwise. Move the spindle
in until the case is touching the cutter with the cutter in the full in position. Rotate the
spindle until the shell lock handle is in vertical or another convenient position, and
tighten the spindle lock. This is an appropriate setting.
The Hornady Cam-Lock
™
Trimmer has a fine adjustment feature on the cutter spindle.
The cutter spindle adjustment nut, o-ring, and lock nut may be tightened to provide
enough tension on the threads to allow changing the setting, while not allowing
unintentional movement in operation. It should be locked in place by further tightening
when adjustment has been achieved. To center the fine adjustment, turn the lock nut
against the adjustment nut. Turn the lock nut and adjustment nut as a unit until the lock
nut touches the handle. Back the lock and adjustment nut away from the handle about
3 turns. This should be about the center of the adjustment range.
4. Rotate the cutter handle with slight inward pressure. Pull back on the handle removing
the pilot from the case mouth. Loosen the shell lock remove the case and measure.
Make length adjustments by turning the adjustment nut relative to the cutter spindle.
One full turn of the adjustment nut will make a .050 change in the trim length. Reinsert
the case and trim again. When desired length has been achieved, make sure spindle
lock and cutter adjustment nut are tight and proceed to trim cases as follows: Insert
case in shell holder, start pilot in case mouth, lock case in place with shell lock, and
rotate handle with slight inward pressure.
NOTE: ALWAYS START PILOT IN MOUTH OF CASE BEFORE LOCKING CASE IN
SHELL HOLDER.
