Cooper Tools AireTool CC-325-HP Operating And Service Instructions

Safety Recommendations

For your safety and the safety of others, read and understand
the safety recommendations and operating instructions before
operating an Airetrol.

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.

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.

When using right angle Airetrols, be sure the throttle is posi­tioned relative to the angle head so that the throttle will not be­come 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.

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 suit­able points to absorb and relieve the operator of the torque reac­tion transmitted by the tool. Tool balance arms are also avail­able 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 mo­tions and/or vibration. Those individuals predisposed to
vasculatory or circulatory problems may be particularly suscep­tible. Cumulative trauma disorders such as carpal tunnel syn-

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 in­creases the load and stresses on the tool parts, which may
result in cage, mandrel or roll breakage. Installation of a filter­regulator-lubricator in the air supply line ahead of the tool is rec­ommended.

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. Be­fore 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 Airet­rol use good balance, sure footing, and proper posture in antici­pation of the torque reaction. Insure that the operator’s hand will
not be wedged or pinched between the work and the tool when
operating.

drome and tendonitis can be caused or aggravated by repeti­tious, forceful exertions of the hands and arms. These disorders
develop gradually over periods of weeks, months and years.

Safety Recommendations

* T asks 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.

* Stressful postures should be avoided and can be controlled
through tool selection and work location.

ADDITIONAL SAFETY RECOMMENDATIONS FOR USE
OF RIGHT ANGLE AIRETROLS

Any user suffering from prolonged symptoms of tingling, numb­ness, blanching of fingers, clumsiness or weakened grip, noc­turnal 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, re­assigning 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.

Follow good machine shop practices. Rotating shafts and com­ponents can entangle and enwrap, and can result in serious in­jures. Never wear long hair, loose-fitting clothes, gloves, ties, or

jewelry when work
exposed rotating shaft.

Drilling or other use of this tool may produce hazardous fumes,
particles, and/or dust. To avoid adverse health effects utilize
adequate ventilation and/or a respirator. Read the material safety
data sheet of any cutting fluids or materials involved in the drill­ing 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.

ing with or near a drill or any machine with

- Smoking Tobacco

- Cold Temperatures

- Certain Drugs

* Avoid highly repetitive movements of hands and wrists, and
continuous vibration exposure.

* 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 pres­sure 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
compressor and that is many cases, poor tool performance
can be improved by minimizing these conditions and/or in­creasing the air line size (ID).

LUBRICATION

It is essential that an automatic (mist type) in-line filter/lu­bricator be used and properly maintained to achieve maxi­mum 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 lubri­cation 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
cavity be kept about half filled through the Zerk fitting 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
the mechanical cleaning action of the drill bits in condenser
tubing and similar applications. The water supply hose and
couplings, NOT SUPPLIED WITH THE TOOL, should only
be of a recommended type to withstand this amount of pres­sure. 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 re­sults. SEE PAGE 13 FOR SELECTION. 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.

USING THE CC-325-HP CONDENSER
CLEANER

The CC-325-HP condenser cleaner can be used with lower
pressure on the scavenging agent satisfactorily, however,
maximum cleaning is done with pressure at 5000 psi. 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
prevent the possibility of contacting someone with the high
pressure water spray. Therefore, it is recommended that
first the bit be placed in a tube, the water flush be turned on
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 cou­pling. It will overheat if no fluid is present to help cool the
parts. Periodically, the thrust bearing No. 16 as shown on
the parts list page 7, should be checked to see that there is
proper lubrication on this bearing.

STORAGE

Before storage of the tool, blow all water out of the tool and
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 se­curely 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 opera­tion.

SERVICE INSTRUCTIONS

SERVICING THE HIGH PRESSURE COUPLING

If after some usage, it is found that the high pressure cou­pling begins to leak excessively, it may be necessary to
replace the “O” rings and back-up rings on the seal sup­port. 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 sug­gested that anytime the support is removed for servicing,
that new “O” ring and back-up rings be installed 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. Push on the support until it touches the bronze bear­ing. Reinstall the coupling retainer No. 22 and tighten se­curely. This will normally repair the coupling and stop the
leakage.

REPLACING THE DRIVE SHAFT

If after considerable usage, it is found 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 loosen­ing the set screws, use a wrench and rotate the spindle in
a counterclockwise rotation which will unthread the thrust
nut from the shaft. Once the thrust nut has been unthreaded,
it will be possible then to remove the shaft from the ma­chine. At this point it is advantageous to remove the thrust
nut No. 14, which will allow servicing of the thrust bearing
and allow inspection of this part to make sure that the thrust
bearing is in good condition before replacement in the
machine. Also, at this point, the bronze bearing No. 21 can
be inspected to make sure that it is not worn to allow ex­cess wobble of the shaft in this area. To install the new
shaft, it will be necessary to press the old shaft from the
gear by resting the gear on the inner diameter and pushing
the large threaded end of the shaft. This will allow the spindle
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
shaft is flush with the 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
prevent problems in operation of the machine after assem­bly. 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
seals are excessively worn, they should be replaced in this
area before reinstalling the shaft. To reinstall the shaft, feed
the shaft down through the housing until the small diam­eter of the shaft protrudes from the front portion of the case.
At this point, place on the shaft the thrust nut along with the
thrust bearing washers, thrust bearing and adjusting nut.
The shaft can then be pushed father into the motor 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 tight­ened into position and again placing an Allen wrench down
through one of the 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
this operation is being performed. As soon as possible, the
front gear cover should be reinstalled and the cap screws
tightened. By continuing rotating the shaft, 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
reaches the end. Then rotate the nut back the entire length
of the opening and at this point, tighten the set screw. Ro-

tate the 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
should not induce preloading on the bearing during assem­bly. 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 cou­pling No. 27. This will allow the entire motor to be removed
from the tool for servicing. Upon replacement of worn parts,
the motor can be reassembled and slid back into the motor
case. Rotor blades should always be replaced when
the motor is serviced. Reinstall the coupling and the large
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

bly. Gears, bearings and grease retainers should be packed
with grease. Essentially, reassembly of all the various sub­assemblies should 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 as­sembly 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
and care be taken to avoid damage to the key when press­ing 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).

All parts should be cleaned and lubricated before reassem-
