1.1 Warnings and notes
Warning notes are identified by a signal word and a pictogram:
• The signal word describes the severity and the probability of the impending danger.
• The pictogram describes the type of danger.
WARNING!
Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION!
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury or property and environmental damage. If this warning is not observed, injuries, property
or environmental damage may occur.
NOTE General notes
include application tips and particularly useful information but no hazard warnings.

1.2 Basic requirements for safe working practices
You should read all instructions.
Failure to observe the instructions listed below can result in serious injuries.
1.3 Operator training
Operators must be trained in correct handling of the tool. The user must make the operating manual avail-
able to the machine operator and ensure that the operator has read and understood it. The tool may be con-
nected, used, serviced and repaired by qualified persons only. The tool may be repaired by authorized
technicians only.
CAUTION!
➔Before initial operation, check that the suspension bail is properly fastened to the bal-
ancer.
➔Work with a maximum working pressure of 101.5 psi (700 kPa) (measured as the air inlet
tube of the tool).
➔120PTHDA: When air inlet from top is used make sure, that plug is properly mounted
accordingly.
➔If you hear unusual noises or vibrations, switch off the tool immediately.
Shut off the air supply immediately.
➔Before carrying out repairs, adjusting the torque or replacing screw bits, disconnect the
tool from the compressed air line.
➔The compressed air line must be depressurized before disconnecting it.
➔Never use the air hose to hold, raise or lower the tool.
➔Air hoses, the suspension bail and fittings must be regularly checked for damage and
wear. Replace if necessary.
➔Always carry out assembly according to Chapter 8 Spare parts, page 25.
➔Use only accessory parts authorized by Cleco
(see product catalog).
➔Adjust the torque using the provided hex wrench only. Never use an angular wrench.
➔Only use screw inserts for machine-controlled fastening tools.
➔Make sure that the screw bits are securely inserted.
➔Inspect screw bits for visible damage and cracks.
Replace damaged screw bits immediately.
➔The operation, maintenance and repair conditions set forth in the operating instructions
must be observed.
➔Follow generally valid and local safety and accident prevention rules.

4. Pull out the hex wrench.
The hole closes automatically when the
tool starts.
5. Carry out the rundown.
6. Check the shut-off mechanism worked
properly, see 4.5.3 Measuring the torque,
page 12.
7. In case of deviations, correct the torque
setting
8. Repeat the rundown.
Requirement Measure
Better shut-off accuracy –
particularly for hard joints.
Increase the number of pulses per rundown.
Recommended number of pulses 6.
➔Reduce the speed
Reducing the noise pressure level ➔Reduce the speed
Reducing vibration ➔Reduce the speed
Shortening the rundown time, particularly for
soft joints.
➔Increase the speed
1. Unscrew the threaded pin using the size 2
hex wrench.
2. To reduce the speed, turn the exhaust air
throttle clockwise.
3. To increase the speed, turn the exhaust
air throttle counterclockwise.

6.1 Service schedule
Regular maintenance reduces operating faults, repair costs and downtime.
This maintenance schedule uses values that are valid for most applications. For a specific service interval,
see 6.1.1 Calculating a customer-specific maintenance plan, page 14.
Implement a safety-related maintenance program that takes the local regulations for repair and mainte-
nance for all operating phases of the tool into account.
CAUTION!
Danger of injury due to unintentional activation
– before service, disconnect the tool from the compressed air supply.

6.1.1 Calculating a customer-specific maintenance plan
A service interval W(1,2,3) depends on the following factors:
T2, Sand VS are variable factors and can differ depending on the specific application.
Example for service interval W2:
After 500,000 rundowns (V),
a specific rundown time of 1.8 seconds (T1)
with an actual fastening time of 3 seconds (soft joint) and
3 completed shifts per day and 750 rundowns per shift:
You have to carry out the maintenance measures marked W2 after an operating time of 133 days.
Factor Value assumed in
6.1, "Maintenance
plan"
Description
VV1 = 100,000
V2 = 500,000
V3 = 1,000,000
Number of rundowns after a maintenance measure is pre-
scribed by Cleco.
T1 1.8 seconds Specific rundown time, measured in life and endurance tests.
T2 2 seconds Actual rundown time, depending on the hardness of the joint.

6.2 Activating the reserve oil
If pulse build-up stops, some of the oil in the pulse unit has been used up. The reserve oil must be activated.
If the equalizing piston reaches the limit stop, oil must be refilled the next time (see 6.3 Refilling oil,
page 16).
1. 2. Align both ends as shown in the illustra-
tion.
3. 4. Turn <68> clockwise till the detent.
5. Turn <68> approx. 2,5 turns anticlock-
wise…
6. …until <70> can be reinserted again.
The reserve oil can be adjusted approx.
1 – 2 times until <71> is at the detent and
<70> can still be reinserted.
If necessary, turn back to the next groove.

Maintenance 6
1. Remove the threaded pin 15 and ball 14.
2. Remove the O-ring 12 and sleeve 13.
3. Align the output drive and claw as shown in the illustration, see 6.2 Activating the reserve oil, page 15.
4. Rotate the equalizing piston 11 clockwise as far as it will go until X= 0 (starting point).
5. Unscrew the equalizing piston 11 counterclockwise by 1,0 turns (reserve oil volume).
6. Connect the pulse unit 8 to the quick disconnect coupling 5using the adapter.
7. Close the shut-off valve 7.
8. Set the working pressure to approx. 73 psi (500 kPa).
9. Slowly open the shut-off valve 7 all the way until the
gauge shows a negative pressure of –13 psi (–90 kPa).
10. Wait approx. 2 minutes until the number of vacuum bubbles has reduced significantly.
11. Close the shut-off valve 7 slowly. The gauge shows atmospheric pressure again. Missing oil is pushed
into the pulse unit 8 .
12. Repeat steps 8 through 11 if necessary until the number of bubbles approaches zero.
13. Uncouple pulse unit 8, unscrew the adapter and add a couple of drops of oil using the injector.
14. Mount the ball 14 and screw the threaded pin 15 into place (0.75+0.25 ft lbf, or 1 +0.3 Nm).
15. Turn the equalizing piston 11 another 2,5 turns counterclockwise, or slightly more if necessary, until
the sleeve 13 can be inserted (oil compensation volume).
16. Install the sleeve 13 and O-ring 12.
NOTE
Small air bubbles that become visible due to the high pressure during filling do not mean that the
pulse unit is leaking.
The filling process is not impaired.

CAUTION!
Skin irritation in case of direct contact with oil.
Wear protective gloves.
CAUTION!
Hydraulic blade is under spring pressure!
Wear protective goggles.
NOTE
Permitted only if filling is guaranteed with oil filling
device, see 6.3 Refilling oil, page 16. The pulse unit
must have cooled to room temperature.
CAUTION!
• Always carry out assembly according to the exploded drawing, see 8 Spare parts, page 25.
Incorrect assembly causes uncontrollable reactions, such as unexpected startup or ejection of parts.
• Tighten all screwed joints of the tool carefully, according to the specifications.
NOTE
To prevent damage, lubricate the gaskets and O-rings using grease (order no. 914392) before
assembly.
