2-7. Procedure for M1010 Ambulance.
During vehicle operations the chain should be stored beneath the driver's seat, looping chain
upon itself, and securing it with a padlock to prevent entanglement with driver's feet. Do not allow
additional locks to remain on the security chain, as this may impair proper stowage.
a. Drill a 27/64 inch hole in the forward end of driver's "Right-Hand" seat riser bracket. Locate hole 9/16 inch from
the top of bracket and 5/8 inch from the edge of bracket. Insert screw in hole with threaded area facing outboard, attach
end of chain with washer and nut, then tighten. After tightening, the nut should be staked to prevent removal (Fig. 6).
b. Position chain around steering wheel spokes and secure with padlock.
c. Parts required are as follows:
