to last gate (19). Slightly open the gate ahead of the clearance (gate 2 if the clearance is between 1 and 20,
or gate 1 if the clearance is between 19 and 20) and move the heel of gate at the clearance to contact the toe
of the adjacent gate. Repeat step 6 until all clearances are acceptable.

of the adjacent gate. Repeat step 6 until all clearances are acceptable.
8. Verify that the servomotor is still in the zero gate position and move if necessary. Loop a wire rope
sling around the gates and draw tight with a ratcheting hoist to hold gates while wicket gate linkage is
attached. Extreme caution must be used to prevent overloading the sling or the hoist. The sling used
must have a rating higher than the hoist, and the hoist must have some type of overload indication.
Attach wicket gate linkage and adjust to hold gates in position. After all of the linkage has been connected,
remove the sling, repressurize the system, move the gates through their full travel several times, and check
clearances.
