Rapid-Air MULTI-STROKE CONTROL - Manual (Page 5)


The air feed needs very little
maintenance. The most important
part to watch is the air. Too much
oil or water in the air can cause
the air feed to start running erratic.
Screws should be checked
periodically to be sure they are tight.
This includes the switch mounting
brackets, if present, as they can
loosen up over time due to the
vibration and high impact movement
of the air feed. A visual check of the
mAintenAnce
air feed every morning before
running it will help assure many
hours of running time. If small
problems are left unchecked,
they can turn into large problems
and down time.
As a general guide for the air feed,
the lubricator oil release adjustment
should be set to one drop of oil for
each 50-80 strokes. (See insert on
lubrication of “O” rings.)
LUBRICATION.OF.“O”.RINGS
The “O” rings furnished with
Rapid-Air feeds are made of a
Buna N Compound designed to
give long life on service with air,
oil and water. This rubber compound
features high abrasion resistance
and good dimensional stability if
the recommendations listed below
are followed.
A filter and lubricator should be used;
the filter to remove grit that would
otherwise act as an abrasive, and
the lubricator to provide an adequate
quantity of oil. for best results, avoid
excess oil.
Paraffin base oils in general will give
the best service. The viscosity should
be 140-170 S.S.u., the API gravity
29.5 minimum, and the aniline point
between 150f and 210f. Variation of
the aniline point from the limits given
is likely to cause either shrinkage or
stretching of the “O” rings.

The group of oils listed below are
generally recommended for Buna
N compound 366y “O” rings. This
grouping is given in good faith, but
because of the constant changes made
in oils by the manufacturers, we cannot
guarantee any consistency of chemi-
cal makeup. All of these oils have an
aniline point of 210, and API gravity of
29.5 minimum, and a viscosity of 140-
170 S.S.u. The base stock is paraffin.
