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 rate of feed IS reached.

lA final adjustmentof the rate of return (retract) can 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).

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

lA manual emergency retract button bleed valve (25) 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.

REMOTEOPERATION

Install a pressurebleed valve - AROpart 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 positionthus startingthe forward stroke of the unit.

Install apressurebleed valve -AROpart number 9600- in valve port marked “R”at the top of the valve housing and connect - using 1/8” i.d.tubing- to 0 remoteMANUALLYoperatedvalve.This valve is used as an emergencyretract in case of o part misalign- ment or such only as the unit, when properly set-up and applied, will automatically retract and return to the start position. Seeset- up procedure.

SPECIALNOTE:The air inlet and remote ports of valve housing have taperedpipethreadsand should not requirethe useof threadsealants, such as sealanttape or pipe joint compounds.Threadsealants,when used improperly, can contaminate air passagesand cause valve or unit to malfunction.

RECOMMENDEDPOWER AIR INLET SYSTEM

Your AROSelf-feed tool is designed todeliver specific horsepower and thrust to achieve high rates at work. To assure the unit will develop this power, core must be token that - the tool Is power

the power air inlet system is correctly sized to permit the proper rate of air flow. Shown is o systemfor a single tool Mot will supply correct delivery. IMPORTANT rated when 90 P.S.I.is present ATTHETOOLDURINGOPERATION.

Shown below is the some system In schematic form.

If two or three units are to be installed, 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
