Cleaning The Machine; Assembling Machine - Stoelting F431 Service Manual

3.7 CLEANING THE MACHINE

The exterior should be kept clean at all times to preserve
the lustre of the stainless steel. A high grade of stainless
steel has been used on the machine to ease cleanup. To
remove spilled or dried mix, simply wash the exterior with
90° to 110°F (32°C to 43°C), soapy water and wipe dry.
Do not use highly abrasive materials as they will mar the
fi nish. A mild alkaline cleaner is recommended. Use a
soft cloth or sponge to apply the cleaner. For best results,
wipe in the direction of the grain of the steel.
A. Clean the rear seal surface from inside of the
machine barrel.
B. Using this sanitizing solution and the large barrel
brush provided, sanitize the barrel by dipping the

brush in the sanitizing solution and brushing the
inside of the barrel.
C. Remove the rear drip tray by pulling from side
panel. Clean and replace drip tray.

3.8 ASSEMBLING 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
lubricants used on food processing equipment be
certifi ed for this use. Use Lubricants only in accor-
dance with the manufacturer's instructions.
A. Assemble all o-rings onto parts dry, without
lubrication. Then apply a thin fi lm of sanitary
lubrication to exposed surfaces of the o-rings.
B. Lubricate rear seal area on auger shaft with a
thin layer of sanitary lubricant. Install the rear
seal o-ring. Lubricate outside of 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
seal adapter (see Figure 3-7).

D. Lubricate the hex drive end of auger with a small
amount of spline lubricant. A small container of
the lubricant is shipped with the machine.
E. Screw the springs onto the studs in plastic fl ights.
Spring must be screwed into the fl ights completely
to provide proper tension (see Figure 3-8).
F. Install the two plastic fl ights onto rear of the auger
and insert part way into machine barrel.
Figure 3-8 Spring Installation
G. Install the remaining plastic fl ights, push the auger
into the machine barrel and rotate slowly until the
auger engages the drive shaft.
H. Apply a thin fi lm of sanitary lubricant to the inside
and outside of the front auger support bearing,
then place on the front of the auger. Assemble
the front auger support onto the auger bearing.
Position the front support on auger so legs do not
interfere with the pin on the back of the front door
assembly. Front door must push auger in slightly
when it is being tightened to prevent the rear seal
from leaking.
