1. Inspect the M-2 parachute release in accordance with WP 0005 00, using the procedures in Table 1.
2. Inspect timing as follows:
A delay release timer will be tested prior to every use. Testing of a timer
will only be conducted with the timer installed and armed within an
assembled serviceable parachute release.
Cut a suitable length of type I, ¼-inch wide cotton webbing for use in fabricating an improvised sling.
Using a length of suitable wire as an aid, pass one end of the webbing length up between the M-2
release side plates, over and around the center of the timer, and back down between the side plates
to a point below the release body.
Attach and suspend a 10-ounce weight to the sling webbing at a point below the release body. This
adds resistance to the timer mechanism keys.
Suspend the release in a vertical position and activate the timer mechanism by pulling the arming
wire from the guide block located on the release face side plate.
Check the time it takes for the release assembly to drop.
When using a 15-second timer, the timer should drop inside the release within a minimum of 12-
seconds and a maximum of 16-seconds. If the timer fails to meet the requirements, it is considered
defective and should be replaced with a serviceable timer and stem assembly from stock.
