Rapid-Air AIR FEED / RAPID MASTER WITH KEYPAD - Manual (Page 4)

The feed guide rollers are adjustable
by loosening the machine screws and
moving the rollers to the desired posi-
tion. For best result, the stock should
be centrally located in the feed.
The notches in the guide rails provide
for coarse feed adjustment of the stop
block. The final feed adjustment for
stroke length is made by the screw
in the center of the stop block. The
final feed adjustment is aided by the
use of accurately dimensioned spac-
ers or gauge blocks placed between
the adjusting screw and the main
cushion bolt, and with the air
pressure turned on to keep the slide
block tight against the main body.
With the air pressure off, the material
is then inserted between the guide
rollers and passed under the feed
clamp. Lift the stock clamp and push
the material through to the starting
position. Turn on the air (75-120 P.S.l.)
and the feed is ready to operate.
The last adjustment, if necessary,
would be the speed adjusting valve.
set-up and maintenance
The valve adjustment is located on
top of the main body on the opposite
side of the actuating valve. Adjust
the screw for minimum impact by
turning clockwise and for faster
speed by turning counterclockwise.
When the impact is high, slippage
is possible resulting in poor
repeatability and also part fatigue.
Refer to the diagram below.
The ram head assembly requires very
little maintenance. There are four
dynamic “0” rings that would need to
be replaced on the rare occasion of
an air leak. These are as follows per

To absorb mechanical shock, reduce
noise and prolong machine life, a
rubber bumper is incorporated into the
assembly. Some stroke accuracy could
be affected by rubber deterioration.
Stroke adjustment will compensate
for any small overall stroke increase.
The rubber bumper (item 52, part no.
35900037), should be examined during
any “O” ring maintenance procedure.
