Do not allow the release assembly to become wet in cold weather. It may freeze, stiffen the webbing, and fail in use causing death or serious injury. 

## WARNING 

j. Inspect each release housing and assembly. Check release assembly for rust. Any rust is cause for immediate grounding of the system until the hardware is replaced. 

k. Inspect all grommets. Grommets must not be bent, dented, loose or burred. Replace the riser if frayed webbing begins to show around the large No. 2 grommet. 

l. Properly reassemble the system ensuring it is done IAW this technical manual. To ensure the risers are not reversed, double-check them. 

## SLACK CHECKER INSPECTION (AR2 Reserve Mounted ONLY) 

After every jump and repack of the reserve parachute, the parachute rigger is to inspect cable extension length with the slack checker as follows: 

1. The MC-4 must have an AR2 and power cable assembly correctly installed and routed to the reserve parachute. Ensure that the position of the AR2 in the pocket is the same as when worn by a jumper. 

2. Open top flap of parachute to expose the reserve ripcord pins. 

3. Slide the metal head of the slack checker under the power cable from the right side so the cable slips into the curved groove between the metal head and plastic handle. Engage the two contact points on the hooked end of the slack checker with the mouth of the end fitting of the power cable housing. The slack checker should be held flat against the parachute pack. The two contact points must be engaged at all times to ensure proper inspection. (Refer to the illustration below).
