ure 21 or 22), and reconnect them in the opposite
hole.
5. Change the reversing block assembly (key 59):
a. Remove the sealing screw (key 56, figure 21 or
22). Inspect the O-ring (key 55, figure 21 or 22) lo-
cated in the recessed area under the sealing screw
head. Replace the O-ring if necessary.
b. Remove the reversing block screw (key 61, fig-
ure 21 or 22) and reversing block assembly (key 59).
Inspect the O-rings (key 55) located in the recessed
area under the reversing block screw head and be-
tween the reversing block assembly and the calibra-
tion adjuster (key 41, figure 21 or 22). Replace these
O-rings, if necessary.
c. Position the reversing block assembly, with O-
ring, on the calibration adjuster (key 41) so that the
nozzle is on the opposite side of the beam (key 44, fig-
ure 21 or 22) from which it was removed. Properly
position the reversing block assembly so that the
alignment pin engages the hole in the calibration ad-
juster. Install the reversing block screw (key 61) with
O-ring (key 55).
d. Install the sealing screw (key 56) with O-ring in
the hole previously covered by the reversing block as-
sembly.
6. Check all connections for leaks with a soap-and-
water solution. Perform the appropriate calibration pro-
cedures.
