Twist handle fully to extend release bar.

Figure 1. Twist handle fully
Check for release bar extension when handle twisted fully.

Figure 2. Check for release bar extension
Twist Handle fully to extend release ramp as shown in Figure 1 and Hold it at the extended position.
Push the “Release Ramp” using a socket extension, nut driver, or similar tool with approx. 10-20 lbs force as shown in Figure 3. Observe the movement of the release ramp. A properly adjusted release ramp will exhibit some spring and when release will return to its original position. If the “Release Ramp” fails to return to its original position and moves more than Approx. 1.5mm (.06 in.) then adjust the release mechanism tension per instructions in Cradle Emergency Release Adjustment.

Figure 3. Push the “Release Ramp”
Check for release bar retraction when handle released to its original position and Release bar should be flushed against the cradle front section as shown in Figure 4. If gap is observed between the cradle and release bar adjust the release mechanism tension as per instructions in Cradle Emergency Release Adjustment.
