Cooper tools Airetool cc-325-hp Training manual

For your safety and the safety of others, read and understand

the safety recommendations and operating instructions before

operating an Airetrol.

Safety Recommendations

Hearing protectors are required in high noise areas, 85 dBA or

greater. The operation of other tools and equipment in the area,

reflective surfaces, process noises and resonant structures can

substantially contribute to, and increase the noise level in an

area. For additional information on hearing protection, refer to

Federal OSHA Regulations, 29 Code of Federal Regulations,

Section 1910.95, Occupational Noise Exposure, and American

National Standards Institute, ANSI S12.6 Hearing Protectors.

Airetool Airetrols are designed to operate on 90 psig (6.2 bar)

maximum air pressure. If the tool is properly sized and applied,

higher air pressure is unnecessary. Excessive air pressure in-

creases the load and stresses on the tool parts, which may

result in cage, mandrel or roll breakage. Installation of a filter-

regulator-lubricator in the air supply line ahead of the tool is rec-

ommended.

Before the tool is connected to the air supply, check the throttle

for proper operation (i.e., throttle moves freely and returns to the

closed position). Clear the air hose of accumulated dust and

moisture. Be careful not to endanger adjacent personnel. Be-

fore removing a tool from service or changing sockets, make

sure the air line is shut off and drained of air. This will prevent

the tool from operating if the throttle is accidently engaged.

It is essential for the safe operation that the operator of an Airet-

rol use good balance, sure footing, and proper posture in antici-

pation of the torque reaction. Insure that the operator’s hand will

not be wedged or pinched between the work and the tool when

operating.

Tools with clutches can stall rather than shut-off if adjusted

over the maximum power output of the tool, or if there is a drop

in air pressure. Operator must then resist the stall torque until

the throttle is released.

Higher torque right angle Airetrols can be equipped with spline

torque reaction mounting plates which accept torque reaction

bars. These bars can be braced against the work or other suit-

able points to absorb and relieve the operator of the torque reac-

tion transmitted by the tool. Tool balance arms are also avail-

able to absorb the torque reaction of the tool while balancing the

weight of the tool for improved ergonomic applications.

Some individuals are susceptible to disorders of the hands and

arms when exposed to tasks which involve highly repetitive mo-

tions and/or vibration. Those individuals predisposed to

vasculatory or circulatory problems may be particularly suscep-

tible. Cumulative trauma disorders such as carpal tunnel syn-

When using right angle Airetrols, be sure the throttle is posi-

tioned relative to the angle head so that the throttle will not be-

come wedged against an adjacent object in the “ON” position

due to torque reaction. The angle head may be repositioned with

respect to the lever to accomodate proper location for the task. If

tool is to be reversed, locate throttle lever in a neutral position

that will prevent entrapment. Refer to operating instructions for

additional information.

For additional information on eye and face protection, refer to

Federal OSHA Regulations, 29 Code of Federal Regulations,

Section 1910.133., Eye and Face Protection, and the American

National Standards Institute, ANSI A87.1, Occupational and

Educational Eye and Face Protection. Z87.1 is available from

the American National Standards Institute, Inc., 1430 Broadway,

New York, NY 10018.

drome and tendonitis can be caused or aggravated by repeti-

tious, forceful exertions of the hands and arms. These disorders

develop gradually over periods of weeks, months and years.

Safety Recommendations

* Tasks should be performed in such manner that the wrists

are maintained in a neutral position, which is not flexed,

hyperextended, or turned side to side.

*Stressfulposturesshouldbeavoidedandcanbecontrolled

through tool selection and work location.

Any user suffering from prolonged symptoms of tingling, numb-

ness, blanching of fingers, clumsiness or weakened grip, noc-

turnal pain in the hand, or any other disorder of the shoulders,

arms, wrists, or fingers is advised to consult with a physician. If

it is determined that the symptoms are job related or aggravated

by movements and postures indicated by the job design it may

be necessary for the employer to take steps to prevent further

occurrences. These steps might included, but are not limited to,

repositioning the work piece or redesigning the workstation, re-

assigning workers to the jobs, rotating jobs, altering work pace,

and/or changing the type of tool used so as to minimize stress

on the operator. Some tasks may require more than one type of

tool to obtain the optimum operator/tool/task relationship.

The following recommendations will help reduce or moderate

the effects of repetitive work motions and/or extended vibration

exposure:

* Use a minimum hand grip force consistent with proper control

and safe operation.

* Keep wrists as straight as possible.

* Keep body and hands warm and dry.

* Avoid anything that inhibits blood circulation.

- Smoking Tobacco

- Cold Temperatures

- Certain Drugs

* Avoid highly repetitive movements of hands and wrists, and

continuous vibration exposure.

ADDITIONAL SAFETY RECOMMENDATIONS FOR USE

OF RIGHT ANGLE AIRETROLS

Follow good machine shop practices. Rotating shafts and com-

ponents can entangle and enwrap, and can result in serious in-

jures. Never wear long hair, loose-fitting clothes, gloves, ties, or

jewelry when working with or near a drill or any machine with

exposed rotating shaft.

Drilling or other use of this tool may produce hazardous fumes,

particles, and/or dust. To avoid adverse health effects utilize

adequateventilation and/or a respirator.Read the material safety

data sheet of any cutting fluids or materials involved in the drill-

ing process.

* Drill bits are sharp, handle them carefully to avoid injury. The

cutting tool maximum speed rating must equal or exceed the

rated speed of the tool.

* Attach the mandrel and the chuck securely to the Airetrol to

prevent tool from jumping off work.

* Use precautions when drilling because of the possibility of the

cutting tool bending or breaking.

* High reaction torque may be experienced by the operator when

reversing tool to remove the expander.

* Drill bits or accessories not centered properly in the chuck can

cause excessive wobble or vibration.

OPERATING INSTRUCTIONS

AIR SUPPLY

To use the CC-325-HP cleaner, it is necessary to use a

compressor with a capacity to supply a sustained air pres-

sure of 90 psi at 200 cfm. It is therefore necessary to use a

air supply hose with a 1” I. D. in order to be sure in having

an adequate volume to the tool. It should also be noted

that long hose runs, air hose quick connects, fittings, etc.

can cause large pressure drops between the tool and the

compressorand that ismanycases,poor tool performance

can be improved by minimizing these conditions and/or in-

creasing the air line size (ID).

LUBRICATION

It is essential that an automatic (mist type) in-line filter/lu-

bricator be used and properly maintained to achieve maxi-

mum operating efficiency and motor life with these tools.

Lubricator should be set to deliver 15 to 20 drops of oil per

minute injected into the air line to assure that proper lubri-

cation is going to the motor. Application of the tool should

govern how frequently it is greased. It is recommended

that the drive shaft cavity be filled periodically through the

Zerk fitting (51) on the side of the tool and that the gear

cavitybekept about half filled throughtheZerkfitting in the

front cover. Use a good quality, extreme-pressure gear

grease. If the tool is to be run for extended periods without

using water or other scavenging agent, The packing gland

nut can be temporarily loosened or the packing removed

to avoid damage to the packing. The packing should be

kept well lubricated.

FLUSHING AGENT

The model CC-325-HP condenser cleaner motor coupling

as installed upon this machine is designed to operate with

(6000 psi) pressure water or scavenging agent to assist

themechanical cleaning action ofthedrill bits in condenser

tubingandsimilar applications. The watersupplyhoseand

couplings,NOT SUPPLIED WITH THE TOOL, shouldonly

beof arecommended typeto withstandthis amountofpres-

sure. Lower pressure may also be used with this supply

hose. The CC-325-HP uses standard Airetool condenser

cleaner shafting and couplings but requires the use of the

Airetool Model “ HP” condenser cleaner drills for best re-

sults. SEE PAGE 13 FOR SELECTION. If the tool is to be

runforextended periods without usingwateror other scav-

enging agent, The packing gland nut can be temporarily

loosened or the packing removed to avoid damage to the

packing. The packing should be kept well lubricated.

USING THE CC-325-HP CONDENSER

CLEANER

TheCC-325-HP condenser cleanercanbe used withlower

pressure on the scavenging agent satisfactorily, however,

maximumcleaningisdonewithpressureat 5000psi.When

connecting the water connections and the shafting to the

cleaner, CAUTION should be taken to make sure that all

joints are tightened properly to prevent the possibility of

leakage of the high pressure. It is recommended that the

water be shut off when the drill bit is not inside the tube to

preventthepossibility of contacting someone with the high

pressure water spray. Therefore, it is recommended that

firstthebit be placed in atube,thewater flush be turnedon

and then the motor be started to drill each individual tube.

It should also be stated that the cleaner should not be run

for extended periods of time without the scavenging fluid

going through the coupling due to the close fit of the cou-

pling. It will overheat if no fluid is present to help cool the

parts. Periodically, the thrust bearing No. 16 as shown on

thepartslist page 7, should be checked to seethatthereis

proper lubrication on this bearing.

Operating & Service Instructions - continued

STORAGE

Beforestorageofthe tool, blow all water out ofthetooland

blow in a generous amount of 10W machine oil to deter

corrosion.

CAUTION: Before operating these tools, always make

sure that the handles (41) are threaded fully and se-

curely into the motor case and that the operator is fully

prepared to safely absorb the full stall torque of the

tool in the event that the drill hangs up during opera-

tion.

SERVICE INSTRUCTIONS

SERVICING THE HIGH PRESSURE COUPLING

If after some usage, it is found that the high pressure cou-

pling begins to leak excessively, it may be necessary to

replace the “O” rings and back-up rings on the seal sup-

port. By removing the coupling retainer No. 22, it will be

possible to grasp part No. 23 and by slightly twisting back

and forth, pull the seal support from the shaft. It is sug-

gested that anytime the support is removed for servicing,

thatnew“O” ring and back-upringsbeinstalled on the seal

support. The back-up ring is installed in the groove first

with the radius portion of the back-up ring facing the small

end of the support. Install in the same groove beside the

back-up ring, one of the “O” rings as furnished. These “O”

rings are of special durometer hardness to stand the 5000

psi pressure. Standard “O”rings and back-up rings should

never be used as they will as they will have a tendency to

extrude from the groove and deteriorate very rapidly. After

installation of the back-up ring and“O” ring in each groove,

three in number, liberally lubricate the seal support and

“O” rings with grease and placing in the shaft and rocking

the seal support back and forth, push the support into the

shaft.Pushonthe support until it touches the bronze bear-

ing. Reinstall the coupling retainer No. 22 and tighten se-

curely. This will normally repair the coupling and stop the

leakage.

REPLACING THE DRIVE SHAFT

Ifafter considerable usage, itisfound necessary to replace

the drive shaft because of wear to the seal area, remove

the socket head cap screws No. 8 that hold the case cover

in place. This will allow removal of the case cover at this

point. With the proper size Allen wrench, reach down

through the thrust nut No. 14, in one of the elongated slots

and loosen the two set screws that are in the thrust nut.

Rotate the shaft until the set screws appear. After loosen-

ing the set screws, use a wrench and rotate the spindle in

a counterclockwise rotation which will unthread the thrust

nutfromtheshaft.Once thethrustnuthasbeenunthreaded,

it will be possible then to remove the shaft from the ma-

chine. At this point it is advantageous to remove the thrust

nut No. 14, which will allow servicing of the thrust bearing

andallow inspection ofthispart tomakesure that thethrust

bearing is in good condition before replacement in the

machine.Also,atthis point, the bronze bearing No. 21 can

be inspected to make sure that it is not worn to allow ex-

cess wobble of the shaft in this area. To install the new

shaft, it will be necessary to press the old shaft from the

gearbyresting the gear on the innerdiameterandpushing

thelargethreaded endoftheshaft.This willallowthespindle

to be pressed from the gear in this direction. Install the

drive key in the new shaft and replace the large drive gear

on the new shaft by pressing it until the diameter of the

shaftisflushwiththe back of the large gear. At this point, it

would be advantageous to run the shaft between centers

to make sure that the gear has been pressed on square to

preventproblemsin operation of the machineafterassem-

bly. If it is found that the gear does not run true, the gear

should be realigned by pressing on the proper spot for

seating the gear squarely on the shaft. If other bearings or

sealsareexcessively worn, they should be replacedinthis

areabefore reinstallingtheshaft. To reinstallthe shaft, feed

the shaft down through the housing until the small diam-

eterof the shaftprotrudes from thefrontportion ofthecase.

Atthispoint, place on theshaftthethrust nut along with the

thrust bearing washers, thrust bearing and adjusting nut.

Theshaftcan then be pushed fatherintothemotor to allow

the shaft to start entering into the rear bronze bearing. As

soon as this is done, the thrust nut No. 14 should be tight-

enedintoposition and again placinganAllenwrench down

throughoneofthe crescent shaped holes in the side of the

thrust nut, the adjusting nut can be screwed on the shaft.

Continue to thread the adjusting nut on the shaft while the

shaft is being rotated and also being pushed rearward as

thisoperationis being performed. As soon aspossible,the

front gear cover should be reinstalled and the cap screws

tightened.By continuing rotating theshaft,adjust the thrust

adjusting nut until a slight resistance is felt on the Allen

wrench when the shaft is rotated. At this point, turn the

shaft and wrench together until it touches the right-hand

side of the crescent shaped opening until the wrench

reachestheend. Then rotate the nut backtheentirelength

of the opening and at this point, tighten the set screw. Ro-

- c o n t i n u e d -

tatethe shaft 180 degrees and tighten the other set screw.

This adjustment should be adequate to allow the bearing

to absorb the hydraulic thrust from the high pressure but

shouldnot induce preloadingonthebearing during assem-

bly. With the seal support installed, the shaft should rotate

freely without binding.

SERVICING THE AIR MOTOR

To service the air motor assembly, remove the large cap

screws in back of the motor coupling and remove the cou-

plingNo.27.Thiswillallowtheentiremotortoberemoved

fromthe tool forservicing. Upon replacementofworn parts,

themotorcan be reassembled and slid backintothemotor

case. Rotor blades should always be replaced when

the motor is serviced. Reinstallthecoupling and thelarge

cap screws and the motor should be ready for operation. It

is important when servicing the motor and gear package,

that lubrication be used on all bearing surfaces and the

gear case should be packed with a semi-solid grease. The

unit should be ready for operation upon the completion of

the above mentioned service.

SERVICING THE THROTTLE VALVE

To service the throttle valve, unscrew the valve retainer

(320 and remove the valve (29), valve spring (42). washer

(30), gasket (31) and valve seat (28). Take care to avoid

damaging the valve seat. Clean and inspect all parts

and replace if worn or damaged.

REASSEMBLY

Allparts should becleanedand lubricated beforereassem-

bly.Gears,bearingsand greaseretainers shouldbe packed

withgrease.Essentially, reassembly of all the varioussub-

assembliesshould be in the reverse order of disassembly,

with particular attention paid to the following points.

1. When assembling the motor, the cylinder pins must go

into the proper holes in the thrust plates and the motor as-

sembly must be inserted into the case oriented such that

the front cylinder pin goes into the proper hole in the motor

case.

2. If replacing the drive shaft (3) or the drive gear (39) is

required, the gear should be supported on its inner flange

andcarebetaken to avoid damage to the key when press-

ing the drive shaft into the drive gear. It is recommended

that the assembly be checked between centers and trued

up if required before assembly into the tool.

3. Care should be taken when pushing the shaft through

the grease retainer (13) and while installing the front cap

(36) with grease retainer (34) over the drive shaft to avoid

damaging the seals.

4. The valve retainer (32) is dimpled for its retaining set

screw (48). The set screw should be secured in place with

Loctite 242 or equivalent.

5. The valve nut (49) should be adjusted so that there is

still a small amount of play in the valve lever (48) to insure

that the valve (29) seals off when the lever is released.

Secure the nut in position with a 1/16” x 1” cotter pin (50).
