16 Use a 5mm Allen key to remove the four (4)
cap screws holding the rear Gauge Base to
the top of the Manifold Block. Then, lift the
Gauge Base and its o-ring (PN 3130) from
the Manifold Block and separate the Gauge
Adapter and its o-ring (PN 2018) from the
Gauge Base (gure 12). Remove the forward
Gauge Base by following the same procedure.
If the comparator is tted with an optional
Fine Adjust Kit, continue to step 18. If not,
you may skip ahead to step 24.
Note: A comparator without the Fine Adjust
option is instead tted with an Accessory
Cap, plus an o-ring that should be replaced.
The screws for the plate will require a 4mm
Allen key to remove. Screws included with
older Fine Adjust Kits will require a 5mm key,
while those included with recent, redesigned
kits will require a 4mm key.
18 Use either a 4- or 5mm Allen key to remove
the four (4) cap screws holding the Fine Ad-
just to the side of the Manifold Block, then
pull the Fine Adjust and its o-ring (PN 2018
or PN 3130) away from the Manifold Block
(gure 13).
19 Use a 3mm Allen key to loosen the set screw
inside the Fine Adjust knob, then slide the
knob o of the piston (gure 14).
20 Use a 15mm box wrench to remove the Fine
Adjust bushing from the body, then slide the
bushing and its o-ring (PN 2018) o of the
piston (gure 15).
21 With the front of the Fine Adjust body facing
toward you, turn the piston clockwise until
the piston threads are clear of the hole in the
back of the Fine Adjust body (gure 16).
22 From the back of the Fine Adjust body, slide
out the piston (gure 17).
