3.3 CORRECTIVE MAINTENANCE
The CNVD-T2 has no internal parts or assemblies
replaceable by the user or organizational level personnel.
Refer to section 3.4 regarding maintenance and/or repair
actions beyond those described in this manual.
Throw-Lever Tension Adjustment
The throw-lever mounting bracket has a locknut that adjusts
the tension required to clamp it to the weapon rail. It is
preset at the factory but may need adjustment when initially
mounted to the rail of the host weapon. If adjustment is
required, the following procedures apply and are performed
with the CNVD-T2 removed from the host weapon:
CAUTION
Creating too much tension with the locknut may
result in damage to the mounting bracket when the
throw-lever is forced against the weapon rail.
Creating too little tension with the locknut may
allow for movement of the CNVD-T2 on the rail.
Never completely remove the locknut from the
mounting bracket.
1. Swing the throw-lever closed (against the body of the
CNVD-T2), then push in the lever lock to engage the
locking mechanism.
2. Using the provided 3/8” box wrench, adjust the locknut
using slight movements (2 or 3 degrees). Turning the
locknut counterclockwise will decrease tension on the
throw-lever. Turning it clockwise will increase tension on
the throw-lever.
