There are two port locks on
the front of the housing.
(See housing front) Each
p
ort lock has a Release
Button, lift the release
button and slide each Port
Lock away from the port
opening. In the unlocked
position the Release Button
will remain in the up
position as shown.
T
o prepare the port for installation, remove the port o’ring and
lightly lubricate it. The port seal is a side-to-side seal and
requires the o’ring to be lightly lubricated for easy installation.
Put a small amount of lubricant on your fingers and draw the
o
’ring through your fingers to lightly lubricate it. Do not stretch
the o’ring. Check that the lip of the port where the o’ring fits
and the sealing surface on the housing are clean. Place the port,
with o’ring into the housing’s port opening. Press down on the
port firmly and evenly until you feel the port slide into place.
Continue to push down on the port and push each port lock
forward until it clicks into place. It may help to slightly rotate
the port as you push in on the port lock. When the port lock
clicks into place the Release Button will drop down against the
port lock.
Check around the perimeter of the port seal to see that the
o’ring is properly sealed and not extruded.

After installing the port, turn the Zoom Control knob on the
housing. If the Zoom Control is difficult to turn, the gear sleeve
may be warped. If so reduce or omit any rubber installed on the
Zoom Clamp. (Fig.H on pg.11).
If the Zoom Clamp is still warped,
use of the #5509.28 package may be required. (See page 8)
