CAUTION:
Some of the following procedures require power to the machine. Take the
necessary precautions to assure that no one operates the machine controls while personnel
are adjusting the push-down components.
42" Divided Cylinder Machines

The push-down stops on these machines consist of brackets attached to the shell and rubber rest
pads, mounted atop the base pads (see
Figure 49: Push-down Travel Adjustment: 42" Div-cyls
(42" Staph Guard
®
), page 97 ) which make contact when the shell pushes down. The rubber rest
pads sit in metal pans and are raised or lowered by adding metal shims to or removing the shims
from inside the pans. Extra shims and adhesive for securing the shims were supplied with your
machine.
There is no specific push-down travel dimension for these machines; however, length of travel
must be adjusted as follows:
1. With the Master switch set to off , and the shell hanging free, measure the gap between each
bracket and base pad.
2. Add or remove shims from the appropriate pads as required to make all four gaps equal and
to insure that no rest pad protrudes completely from its metal pan.
Test for equal length of travel at all four locations as follows:
3. With four sheet metal shims of equal thickness, set one shim on top of each rubber rest pad,
such that at least a one inch length of the shim overhangs the outside edge of the pad.
4. Set the
Master switch
to
manual
, causing the shell to push-down.
