FEEDRATECONTROLVALVES

lTurnvalve (23), marked“R”on top of housing,approximately1-1/2 turns counterclockwise (open).

lTurn the other valve (23), marked “F”on top of housing, clock-

wise until closed (do not tighten too snugly).

lStartunit and slowly turn valve (23) marked“F”counterclockwise

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

lA final adjustmentof the rate of return (retract) con be made with the valve (23) marked “R”on housing.

MANUALOPERATION

lInstall button bleed valve (25) in either the “F”port located at top of valve housingor the “F”port locatedat the rearof valve housing NOTE:Unused port must be plugged with pipe plug (24).

lDepressbutton 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 depressedbleed valve (25) marked “R”to retract the unit See set-up procedure.

lA 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.

REMOTEOPERATION

Install a pressurebleed valve - AROport 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 are- mote operated valve which, when actuacted, feeds oil pressure to the pressure bleed valve. Pressurebleed valve will bleed the air from “F”port of valve housing causing spool valve in housing to shift to the forward feed positionthus startingthe forward stroke of the unit

Install a pressurebleed 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 remoteMANUALLYoperatedvalve.This valve is used OSan emergency retract in case of a part misalign- ment or such only OSthe unit, when properly set-up and applied, will automatically retract and return to the start position. Seeset- up procedure.

Referto page 9 for plumbing and schematic diagrams.

SPECIALNOTE:The air inlet and remote ports of valve housing hove taperedpipethreadsand should not requirethe useof threadsealants, such OSsealant tape or pipejoint compounds.Threadsealants,when used improperly, can contaminate air passagesand cause valve or unit to malfunction.

RECOMMENDEDPOWER AIR INLET SYSTEM

Your AROSelf-Feedtool 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 token that the power air inlet system is correctly sized to permit the proper rate of air flow. Shown is a systemfor a single tool that will supply correct delivery. IMPORTANT- the tool is power

rated when 90 P.S.I.is present ATTHETOOLDURINGOPERATION.

Shown below is the same system in schematic form.

F = FILTER

R = REGULATOR

L = LUBRICATOR

It two or three units ore to be instolled, each unit should be supplied with a system like that shown below or use system like that above for each tool

FILTER MODEL F25231-110

REGULATOR MODEL R27231-100

LUBRICATOR MODEL L26221-110
