the bushing onto the auger support and install the
auger support into the front of the auger. Rotate
the auger support so that one leg of the support
points straight up.
I.
Assemble the air bleed valve o-ring onto the air
bleed valve. Position the o-ring into the groove
close to the wide part. Apply a thin fi lm of sanitary

3.7 ASSEMBLING THE MACHINE
To assemble the machine parts, refer to the following steps:
NOTICE
Petrol-Gel sanitary lubricant or equivalent must be
used when lubrication of machine parts is specifi ed.
NOTICE
The United States Department of Agriculture and
the Food and Drug Administration require that lubri-
cants used on food processing equipment be certi-
fi ed for this use. Use lubricants only in accordance
with the manufacturer’s instructions.
A.
Assemble all o-rings onto parts dry, without
lubrication. Then apply a thin fi lm of sanitary
lubricant to exposed surfaces of the o-rings.
B.
Install the rear seal o-ring. Lubricate the outside
of the rear seal o-ring with sanitary lubricant.
C.
Install the stainless steel rear seal adapter into
the rear seal dry (without lubricant). Lubricate the
inside surface of the rear seal adapter, including
the adapter o-ring, and install it onto the auger
shaft. DO NOT lubricate the outside of the rear
auger seal (Fig. 3-6).
D.
Lubricate the hex drive end of the auger with a
small amount of spline lubricant. A small container
of lubricant is shipped with the machine.
E.
Screw the springs onto the studs in the plastic
fl ights. The springs must be screwed into the
fl ights completely to provide proper compression.
F.
Install the two plastic fl ights onto the rear of the
auger and insert it part way into the freezing
cylinder.
