FEED RATE CONTROL VALVES

REMOTE OPERATION

Turn valve (23), marked "R" on top of housing, approximately 1-1/2

turns counterclockwise (open).

Turn the other valve (23), marked "F" on top of housing, clock-

wise until closed (do not tighten too snugly).

Start unit and slowly turn valve (23) marked "F" counterclockwise

(open) until the desired forward rote of feed

reached.

A final adjustment of the rate of return (retract) con be made with

the valve (23) marked "R" on housing.

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 housing

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) con 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

port 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 a re-

mote operated valve which, when actuacted, feeds oil 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 part 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 an emergency retract in case of a part misalign-

ment or such only OS the unit, when properly set-up and applied,

will automatically retract and return to the start position. See set-

up procedure.

Refer to page 9 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 OS 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

the power air inlet system is correctly sized to permit the proper rate of air flow. Shown is a system for a single tool that will supply correct delivery. IMPORTANT

rated when 90 P.S.I. is present AT THE TOOL DURING OPERATION.

Shown below is the same system in schematic form.
