FEED RATE CONTROL VALVES

REMOTE OPERATION

lTurnvalve (23), marked“R”an 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.

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 depressedbleed 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 usedto immediately retract the unit in case of misaligned part or other emergency. Valve not furnished.

Install a pressurebleed 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 pressurebleed valve. Pressurebleed 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 pressurebleed valve-ARO port number 9600 - in valve port marked “R”at the TOPof the valve housing and connect - using 1/8” i.d. tubing - to o remote MANUALLYoperated valve. This valve is used OSon 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 11for plumbing and schematic diagrams.

SPECIALNOTE: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.

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 taken that the power air inlet system is correctly sized to permit the proper rote of air flow. Shown is a systemtar o single tool that will supply correct delivery. IMPORTANT-the tool ISpower rated when 90 P.S.I.is present AT THETOOLDURINGOPERATION.
