9. If necessary, remove the three male elbows and the straight fittings
from the air cylinders.
10. Inspect all parts for wear or damage and replace as necessary.
11. Install the male elbow and straight fitting to the left air cylinder, as
shown, and label them 107 and 106 respectively. Install the two male
elbow fittings to the right air cylinder, as shown, and label them 107
and 106 respectively.

10 - 32 x 5/8 cap screws. Perform the same for the right air cylinder
assembly. Loosely install the strap to the air cylinder pistons using the
two 6 - 32 x 3/4 cap screws as shown and move the strap up and down
to self align the air cylinders. Tighten the two 6 - 32 x 3/4 cap screws
securing the strap to the air cylinder pistons and the four 10 - 32 x 5/8
cap screws securing the air cylinder assemblies to the plate.
15. Manually move the air cylinders through the entire stroke to ensure
there is no binding. If any binding is present, loosen the screws
securing the cylinder bracket to the plate and the air cylinder to the
cylinder bracket and retighten.
16. Install the strap and sensor switch to the left switch bracket using the
two 8 - 32 x 7/8 cap screws. Perform the same for the strap and sensor
switch on the right switch bracket.
