Installation
Installation Requirements
Air Quality
■For optimum performance and maximum product life we recommend the use of compressed air with
a maximum dew point of +10°C (50°F). We also recommend to install an Atlas Copco refrigeration
type air dryer.
■Use a separate air filter which removes solid particles larger than 30 microns and more than 90% of
liquid water. Install the filter as close as possible to the product and prior to any other air preparation
units to avoid pressure drop.
For impulse/impact tools make sure to use lubricators adjusted for these tools. Regular lubricators will
add too much oil and therefore decrease the tool performance due to too much oil in the motor.
Make sure that the hose and couplings are clean and free from dust before connecting to the tool.
Both lubricated and lubrication free products will benefit from a small quantity of oil supplied from a lu-
bricator.

Operation
Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic guidelines and see if you can
identify areas for improvement in posture, component placement, or work environment.
■Take frequent breaks and change work positions frequently.
■Adapt the work area to your needs and the work task.
■Adjust for convenient reach range by determining where parts or tools should be located to avoid
static load.
■Use workstation equipment such as tables and chairs appropriate for the work task.
■Avoid work positions above shoulder level or with static holding during assembly operations.
■When working above shoulder level, reduce the load on the static muscles by reducing the weight
of the load. You can also reduce the load on the static muscles by holding the load close to the
body.
■Make sure to take frequent breaks.
■Avoid extreme arm or wrist postures, particularly for operations requiring a degree of force.
■Adjust for convenient field of vision by minimizing movement of the eyes and head during the work
task.
■Use the appropriate lighting for the work task.
■Use ear protection equipment in noisy environments.
■Use dust extraction system or mouth protection mask in dusty environments.
Operating Instructions
Changing the Rotational Direction
Air Pressure Monitoring, RE-signal
It is possible to connect the tool to a pressure monitoring equipment to monitor the tightening. The pres-
sure signal from the tool (differential pressure over the motor) can be used to detect:
■Missed fasteners
■Trigger release before set torque is reached

EP8PTI70 HR10-MT EN Operation

■Stripped threads
■Cross-threading
■Re-hits
■Drop in air supply
To connect the tool to a pressure monitoring equipment we recommend using a Reporting Connection Kit,
see Accessories https://servaid.atlascopco.com.
The pressure monitoring equipment does not measure torque.

Air Pressure Signal Diagram
Optimizing Performance of the Tool
Recommended number of pulses
A Pulse tool well suited for your application should reach the target torque (with shut off) within 5-20
pulses. The number of pulses it takes for the tool to reach target torque can be measured with an ana-
lyzer. The tightening time can also be used as a guide, to know if the tool is appropriate for your applica-
tion:
■≤1 second for tools up to 30Nm
■≈1 second for tools up to 80Nm
■≈2 seconds for tools up to 150Nm

Operation EN EP8PTI70 HR10-MT
10 © Atlas Copco Industrial Technique AB - 9839 0664 01
■≈5 seconds for tools up to 450Nm
■≤10 seconds for tools up to 850Nm
If the target torque is achieved with less than 5 pulses (= short tightening time), the torque scatter will in-
crease and it can be difficult to adjust to the right level, especially on hard joints.
If the target torque is achieved with more than 20 pulses (= too long tightening time) the wear will in-
crease and more frequent oil filling and service will be required. Too long tightening time, in combination
with high production rate, may also result in excessive heating of the oil. In that case the power will de-
crease with longer tightening time and sometimes no shut off.
If the target torque is achieved with less than 5 pulses this can be fixed by:
■Decreasing the air pressure.
■Reducing the speed by means of the AutoTrim or Trim valve.
■If the above is not possible or does not give wanted results, a smaller tool may be a better choice.
If the target torque is achieved with more than 20 pulses this can be fixed by:
■Increasing the dynamic air pressure to 6-7 bar for standard EP tools, or up to 5 bar for low pressure
EP L-tools.
■Adjust the AutoTrim or Trim valve to give maximum power/speed.
■If the above is not possible or does not give wanted results, a bigger tool may be a better choice.
When changing the air pressure, the target torque must be measured again and adjusted if needed.
MultiTrim Function
The design of PTI-MT tools combines the advantage of both AutoTrim and Trim function - MultiTrim - in
the same tool. The tools are factory set at AutoTrim function and can easily be change to Trim function
when suitable for the application.
When to Use AutoTrim Valve or Trim Valve
AutoTrim Valve
■For applications where the tool is used to tighten both hard and soft joints.
Trim Valve
■For applications where the tool is used for tightening joints with similar characteristics.

■If the valve is too closed, the AutoTrim will not shift to full speed and power when pulsing starts. Turn
the valve counter clockwise 90 degrees to find the correct switching point. Repeat until correct switch-
ing point is reached.
■If the valve is too open, the AutoTrim will shift to full speed and power too quickly (during rundown).
Turn the valve clockwise 90 degrees to find the correct switching point. Repeat until correct switching
point is reached.
Re-setting the Switching Point of the AutoTrim Valve
1. Close the switching valve completely, by turning it clockwise, until it stops.
2. Open the valve counter clockwise 6.5 turns with an Allen key.
3. If needed, turn the valve 90 degrees at a time to find the correct switching point, as described above.
4. If correct switching cannot be achieved with 5-8 turns, from fully closed, then service may be needed,
see Service section.

■Longer tightening time.
■No shut-off.
Relevant Information
2Switching to AutoTrim Function [11]
Setting of Tightening Torque
The adjusting screw (the slotted screw) is the only screw that initially should be adjusted. Start at a low
torque adjustment and gradually increase the setting until you reach the desired torque level. See detailed
illustrations for setting of the tightening torque when using AutoTrim function and Trim function respec-
tively.
Using the tool at a higher torque, than recommended maximum torque, might result in improper function
and faster wear.
Always check the setting on your actual joint.
Relevant Information
2Setting of Tightening Torque When Using AutoTrim Function [15]
2Setting of Tightening Torque When Using Trim Function [16]
Initial Setting of Torque
To minimize the risk of damage to the actual joint we recommend to set the torque slightly lower on the
test joint than the torque wanted for the application. Make sure to use the same equipment, such as for
example extensions, sockets and air pressure on the test joint as will be used on the actual joint.
A Torque transducer IRTT
B Test joint
C ST Analyzer
Make sure to always verify the torque settings on your actual joint.

Torque Check - Residual Torque Measurement on Actual Joint
1. Make sure to use the same equipment, such as extensions, sockets and air pressure during the tight-
ening, as will be used on the actual tightening application.
2. When performing a torque check on the actual joint we recommend using an ST Wrench with resid-
ual torque measurement* setting.

Service
General Service Information
If the tool is not working properly, take it out of operation for inspection. Preventive maintenance is recom-
mended at regular intervals. See detailed information on Preventive Maintenance.
■Make sure to use the service tools, service kits and spare parts recommended by Atlas Copco.
■Make sure to follow the Service instructions provided by Atlas Copco.
Make sure to work in a clean environment and that all parts are cleaned before re-assembling. For-
eign particles, even small fibers from paper tissue, may affect the service life of the Pulse unit.
Tightening of Threaded Connections
The tightening torque indicated in the exploded views will give the right clamping force and prevent parts
from loosening. It is important not to exceed the clamping force, these parts must be able to open up with-
out being damaged at service. After some time of operation and in special circumstances, depending on
application and usage, the parts may however loosen somewhat. The tightening torque can then be in-
creased by 10-20% and some type of low or medium thread locking fluid can be applied.
Maintenance Instructions
Daily Inspection
■Make sure that the tool is in good condition, no visual damage.
■Make sure that the air connection and air installation is done correctly. Listen for any air leakage.
■Make sure that sockets and extensions have no visual damage.
