728 SerieAIR MOTORS

IMPORTANT SAFETY INFORMATION ENCLOSED.READ THIS MANUAL BEFORE OPERATING.

FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULDRESULT IN INJURY.

SAFETY RECOMMENDATION:

? Always bleed of the air supply anddisconnect the air supply hose beforeinstalling, removing or adjusting anyaccessory on this tool, or beforeperforming any maintenance on thistool.

For top performance and maximumdurability of parts, operate this tool at 90psig (6,2 bar/620kPa) maxi AIRPRESSURE WITH ¼” (6mm) AIRSUPPLY HOSE.

LUBRICATION:Oil: Ingersoll-Rand N°10 LubricantGrease: Ingersoll-Rand N°28Lubricant.We recommend the use of an air linelubricator in the air supply line. Attachthe unit as close to the tool as practical.Where the lubricator cannot bepermanently mounted, we recommendusing an Ingersoll-Rand N° NL-4Lubricator. For permanent installations,we recommend using an Ingersoll-RandC08-C2-FKG0, Filter-Lubricator-Regulator unit.

These units have ¼” pipe tap inlet andoutlet and 148ml oil capacity. Largercapacity may be used, but do not use aunit having less than a ¼” pipe tap inletand outlet. Adjust the lubricator so thereis a slight oil mist in the exhaust.Whenever the gear end of the motor isdisassembled, lubricate the gear train asfollows:For single reduction Motors, workapproximately 15cc of the recommendedgrease into the gearing and around thebearings on the spindle.For double reduction Motors, workapproximately 19cc of the recommendedgrease into the gear train and around thebearings on the spindle.For triple reduction Motors, worksapproximately 22cc of the recommendedgrease into the gear train and around thebearings on the spindle.

The use of other than genuine Ingersoll-Rand replacement parts may result in decreasedMotor performance and increased maintenance, and may invalidate all warranties.

Repairs should be made only by authorised, trained personnel. Consult your nearestIngersoll-Rand Authorised Service center.

It is the responsibility of the employer to place the information in this manual into thehands of the operator.

OPERATIONAL DATA

1- Operating temperature

The 728 motor serie has been design for theoperating ranges from –30 to +100°C.However for any application where thetemperature will be below +5°C may causefreeze-up if moisture is in the line. For suchapplication, we will recommend to use an airDryer

2- Operating Feed Pressure

The 728 serie motor may be operated from 2bars up to 7 bars, in order to get consistentperformances.

3- Attitude

The 728 motor serie can be operated in allpositions providing adequat airline lubrication.

4- Feeder media

The 728 motor serie is design in order to useair compressed or nitrogen. Never Use naturalgas without getting approval fromINGERSOLL-RAND .

5- Filtration

Always use clean, dry air. A 60 micron filtrationor better is recommended.

6- Lubrication

Before starting the air motor ,detach the airhose and inject about 2.5 cc of IRAX N°50P oilor SAE 10.Choose the lubricator suitable for the flowrequired.The lubrication rate is as follow : 3 drops perminute per H.P for continuous operation.

6 drops perminute per H.P for intermittent operation.

7- Environment

The 728 motor serie can be used without anyrestriction ,just make sure the filtration andlubrication are goodThe material used for manufacturing the motorgive the possibility to use the 728 SERIE evenin underground application. For applicationunder water, it is recommended to requestengineering recommendation before to selectand use the air motor. In any case under waterit is necessary to pipe away the exhaust.

8- Expected life

The life of the motor will depend of the qualityof the air compressed, the lubrication,application.For more information we will recommend tocontact our service department or the nearestIngersoll-Rand Authorized Distributor.

LUBRICATION

Before starting the air motor, detach the air hose and inject about 2.5 cc of IRAX N°50P oil or SAE 10oil. Choose the lubricator suitable for the flow required, make sure the lubricator is not install to farfrom the Air Motor, the maximum distance will be 5 meters.The lubrication rate is as follow : 3 drops per minute per H.P for continuous operation.

6 drops per minute per H.P for intermittent operation.In case you want use another oil than IRAX N°50P Use the following table for your selection.

TYPICAL INSTALLATION

A four-way Throttle Valve (whether manually, remotely, or automatically controlled)must be usedin the air supply line to serie 728 Reversible Motors, as one motor inlet is expelling secondary exhaustair, and therefore must be open to atmosphere whenever the opposite inlet is admitting live air to themotor. The use of any throttle valve that close or restricts the secondary exhaust line will result insufficient back pressure to drastically reduce the speed and power of the motor.

When the application requires Throttle Valve in each air line, the two three-way valves must beused.
