FEED RATE CONTROL VALVES
l Turn valve (23), marked “R” an top of housing, approximately 1-1/2
turns counterclockwise (open).
l Turn the other valve (23), marked “F” on top of housing, clock-
wise until closed (do not tighten too snugly).
l Start unit and slowly turn valve (23) marked “F” counterclockwise
(open) until the desired forward rate of feed IS reached.
l A final adjustment of the rate of return (retract) can be made with
the valve (23) marked “R” on housing.
REMOTE OPERATION
MANUAL OPERATION
install button bleed valve (25) in either the “F” port located at top
of valve housing or the “F” port located at the rear of valve hous-
ing. NOTE: Unused port must be plugged with pipe plug (24).
Depress button bleed valve (25) marked “F” on valve housing.
The unit will start in the forward (advancing) mode and continue
to feed forward until the adjusting screw “B” has depressed bleed
valve (25) marked “R” to retract the unit. See set-up procedure.
A manual emergency retract button bleed valve (25) can be in-
stalled in “R” port at top of valve housing if desired. This valve
con be used to immediately retract the unit in case of misaligned
part or other emergency. Valve not furnished.
Install a pressure bleed valve-ARO port number 9600 - in valve
port marked “F” at either the top or rear of valve housing
Connect pressure bleed valve - using 1/8” i.d. tubing - to o
remote operated valve which, when actuated, feeds air pressure
to the pressure bleed valve. Pressure bleed valve will bleed the air
from “F” port of valve housing causing spool valve in housing to
shift to the forward feed position thus starting the forward stroke
of the unit.
Install a pressure bleed valve-ARO port number 9600 - in valve
port marked “R” at the TOP of the valve housing and connect -
using 1/8” i.d. tubing - to o remote MANUALLY operated valve.
This valve is used OS on emergency retract in case of a port mis-
alignment or such only as the unit, when properly set-up and ap-
plied, will automatically retract and return to the start position.
See set-up procedure.
Refer to page 11 for plumbing and schematic diagrams.
SPECIAL NOTE: The air inlet and remote ports of valve housing hove
tapered pipe threads and should not require the use of thread
sealants, such as sealant tape or pipe joint compounds. Thread
sealants when used improperly can contaminate air passages and
cause valve or unit to malfunction.
RECOMMENDED POWER AIR INLET SYSTEM
Your
ARO Self-Feed tool
is
designed to deliver specific horsepower and thrust to achieve high rates of work. To assure the unit will develop this power care must be taken that
the power air inlet system is correctly sized to permit the proper rote of air flow. Shown is a system tar o single tool that will supply correct delivery. IMPORTANT -the tool IS power
rated when 90 P.S.I. is present AT THE TOOL DURING OPERATION.
Shown below Is the same system In schematic form.
F = FILTER
R = REGULATOR
L = LUBRICATOR
F-R-L- MODEL C28221-810
If two or three units are to be installed, each unit should be supplied with o system like that shown below or use system like that above far each tool.
