the screw on the right side of the lock bar tube (see Figure 4).
With the Allen wrench, push into the tube to engage the screw head (the lock bar
is spring-loaded on the opposite end).
NOTE: If the entire lock bar tube rotates while you are trying to remove the
screw, wrap some fabric or paper over the lock bar. Then grasp the wrapped sec-
tion of the lock bar with a pair of pliers to hold the tube and prevent it from
rotating while you remove the screw.
