key ring. (See Figure 10B on Page 49.) Ensure that the ground control chain is freely looped
through the roof eave bracket and chain holder. After removing the slack in the chain while the lid
is fully closed and in latched position, re-position the key ring 2" below the roof eave bracket.
(See Figure 10F.) Re-adjust the existing handle and key ring so the handle is positioned for easy
access from ground. (See Figure 10G.) Check to make sure that the key rings allow the cap to fully
close, but will not allow the chain enough slack on top of the cap to become wrapped around the lever
arm in a high wind condition.
