>From the manual:

"Special Tuning Note:
If two different capacitance settings for C4E (Osc) can be
found at which the ouput is at maximum, be sure to use only
the setting corresponding to the higher capacitance.
The maximum capacitance position of the rotors of all air 
trimming
 capacitors (except the auxiliary trimmers C4F and C4G under
 the gang capacitor shield) is obtained when the top of the 
"cross"
or "arrow" on the rotor shaft is lined-up with the fixed fiducial 
mark
on the dust shield, IF can or chassis.  Turning the rotor 180 
degrees
in either direction reduces the capacitance to a minimum.
When trimming a circuit always tune in a counter-clockwise motion
from the maximum setting.  This will always result in a setting 
such
 that a clockwise motion increases capacitance...."
