FEED RATE CONTROL VALVES

Turn valve (25), marked "R" an tap of housing, approximately 1-1/2

turns counterclockwise (open).

Turn the other valve (25), marked "F" on top of housing, clock-

wise until closed (do not tighten to snugly).

Start unit and slowly turn valve (25) marked "F" counterclockwise

(open) until the desired forward rote of feed is reached.

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

the valve (25) marked "R" on housing.

MANUAL OPERATION

Install button bleed valve (27) 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 (26).

Depress button bleed valve (27) 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 (27) marked "R" to retract the unit. See set-up procedure.

A manual emergency retract button bleed valve (27) can be in-

stalled in "R" port at top of valve housing if desired. This valve

can be used to immediately retract the unit in case of misaligned

part or other emergency. Valve not furnished.

REMOTE OPERATION

Install a pressure bleed valve -ARO part 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 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 part number 9600 - in valve

port marked "R" at the top of the valve housing and connect -

using 1/8" i.d. tubing - to a remote MANUALLY operated valve.

This valve is used as on emergency retract in case of a part 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 9 for plumbing and schematic diagrams.

SPECIAL NOTE: The air inlet and remote ports of valve housing have

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

MODEL 23903-200 CONNECTOR

1/4- FEMALE N.P.1.F

MODEL 23103300 COUPLER

3/8 FEMALE N.PT.F.

Your ARO self-feed tool is designed to deliver specific horsepower and thrust to achieve high rates of work. To assure the unit wilt develope this power, care must be token that

the power air inlet system Is correctly sized to permit the proper rate of air flow. Shown is o system for 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 some system in schematic form.
