MONTHLY MAINTENANCE
Spray Pipes
Remove the pipe plug from the ends of the water
spray pipes and clean using a Somaca circular wire
brush. This brush is specific to the Washer size. For
more information, contact Sommer and Maca
Industries, Inc. for the brush part number for the
Washer size.
Washer Surfaces and Pans
Clean the entire Washer from excessive grease and
accumulated dirt. Remove broken glass and cullet
from the pans.
Clean the dividers and covers. Scrape off built-up
calcium and soap deposits. Flush the interior of the
Washer with clean water using a garden hose nozzle.
BRUSH ADJUSTMENT
Brush Adjustment for Wear
Remove the brush drive belts and raise the upper
frame.
Measure and record the smallest diameters of the
upper and lower brushes (using a caliper or
circumference (
pi
) tape).

Lower Brush Adjustment
Cover the brush and the two adjacent rollers with
a piece of glass that is the full width of the
conveyor. Using bar soap, rub the bottom side of
the glass for the entire length of the brush and
approximately 6 inches wide before placing it
over the brush. (When using this technique, the
brushes
must be dry
.)
Loosen the lower locking nuts on the brush
supports.
Turn the upper nuts to adjust the brush position on
the glass. A clockwise turn will raise the brush
into the glass; i.e., a counterclockwise turn will
lower the brush away from the glass. Each end of
the brush will be adjusted to achieve a uniform
area of contact (flat stripe) as seen on the glass
when the brush is rotated by hand.
The following is a list of desired flat stripe widths,
made into the soap film, for the specific brush
diameters:
21
/
32
inch width for 3½ inch diameter brush
25
/
32
inch width for 5 inch diameter brush
7
/
8
inch width for 6 inch diameter brush
Measure the distance between the brush shaft and
the lower frame rail. Adjust the brush shaft
equally on both ends and tighten the lower locking
nuts.
Adjust the glass thickness indicators to the lowest
setting, “
0 –
¼ ”.
Upper Brush Adjustment
Method 1
Calculate the correct distance between the brush
centers and the exact worn brush diameters
measured previously using this formula:
DISTANCE BETWEEN BRUSH CENTERS
(
D
1
+ D
2
)
/

+

/

Adjust both ends of the upper brush until this
distance from the shaft centers is obtained from
the lower brush.
Method 2
Loosen the lower locking nuts on the upper brush
supports. Use the upper locking nuts to raise or
lower the brush.
Adjust the brush until it touches the lower brush.
Rotate the upper brush by hand. Either resistance
will be felt through the brush or the rotation of the
lower brush will be observed to verify contact
with the brushes. Measure the distance between
the brush centers. Adjust the opposite end of the
brush to the same distance. Spin the upper brush
by hand again and feel the resistance. If there is
too much resistance, repeat the adjustment
procedure until acceptable.
Tighten the lower locking nuts.
