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.

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.

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

8345-B, 8245-B specifications

Ingersoll-Rand is a renowned name in the field of air compressors, and their series of portable air compressors, specifically the models 8245-B and 8345-B, stand out for their performance and reliability. These models are often utilized in construction, automotive, and industrial applications, delivering consistent airflow and power.

The Ingersoll-Rand 8245-B is designed for efficiency and ease of use. With a robust 8-gallon tank, it provides a steady supply of compressed air for various tools and equipment. This model boasts a powerful 3.5 HP engine, which allows it to achieve a maximum pressure of up to 135 PSI. The lightweight and compact design make it easy to transport, while the integrated control panel offers user-friendly operation, allowing for quick adjustments to pressure settings.

Similarly, the Ingersoll-Rand 8345-B elevates the standards with its enhanced features. This model increases the tank capacity to 10 gallons and is equipped with a more powerful 5 HP engine. This upgrade enables it to flow a greater volume of air – up to 24 CFM at 90 PSI. This higher airflow rate makes it ideal for heavy-duty applications that demand sustained usage over extended periods. It maintains a maximum pressure of 145 PSI, ensuring that tools always have sufficient air supply.

Both models incorporate advanced technologies to enhance performance. The inclusion of an oil-lubricated pump contributes to improved efficiency and lower operating temperatures, prolonging the life of the compressor. The design minimizes vibration and noise, making them suitable for use in environments where quieter operation is required. These air compressors feature a durable construction, with corrosion-resistant materials ensuring their longevity even in challenging working conditions.

Safety is also a priority in both models, as they come equipped with protective features like thermal overload protection, which prevents overheating and potential damage to the unit. Additionally, the easy-to-read pressure gauges ensure that users can monitor and adjust pressure levels effectively.

The versatility and reliability of the Ingersoll-Rand 8245-B and 8345-B make them suitable options for both professional and DIY users. Their robust construction, powerful engines, and innovative technologies set them apart as dependable choices in any job requiring a reliable source of compressed air.
