Installation
Installation of vibrating tools
It is recommended that a minimum length of 300 mm of flexible hose for compressed air is inserted between a vibrating tool and the quick-action coupling.
Air quality
For optimum performance and maximum machine life we recommend the use of compressed air with a maximum dew point of +10°C. We also recommend the installation of an Atlas Copco refrigeration-type air dryer.
Use a separate air filter of type Atlas Copco FIL. This filter removes solid particles larger than 15 microns and also removes more than 90 % of liquid water. The filter must be installed as close as possible to the machine/equipment and prior to any other air preparation unit such as REG or DIM (please see Air Line Accessories in our main catalogue). Blow out the hose before connecting.
Models which need air lubrication:
The compressed air must contain a small quantity of oil.
We strongly recommend that you install an Atlas Copco oil lubricator (DIM). This should be set according to air consumption by the air line tool according to the following formula:L = Air consumption (litre/s)
D = Number of drops per min (1 drop = 15 mm3)
L* 0.2 = D
this applies to the use of long work cycle air line tools. A single point lubricator type Atlas Copco Dosol can also be used for tools with short running cycles.
Information about Dosol settings may be found under Air Line Accessories in our main catalogue.
Lubrication-free models:
In the case of lubrication-free tools it is up to the customer to decide on the peripheral equipment to be used. However, it is no disadvantage if the compressed air contains a small quantity of oil e.g. supplied from a fog lubricator (DIM) or Dosol system.
Note – This does not apply to turbine tools, which should be kept oil free.
Compressed air connection
The machine is designed for a working pressure of 6–7 bar = 600–700 kPa = 87–102 psi.
Blow out the hose before connecting.
Installation proposal
Choosing the correct couplings, hose and clamps can be a troublesome digging into details. To save your time and to ensure correct capacity of the airline installation, from the tapping point to the tool, we offer you an installation proposal.
For more information please read, Atlas Copco Industrial Power Tools catalogue Ordering No. 9837 3000 01.
Handling
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.
Use of a machine over recommended maximum torque might result in improper function and faster wear.
Always check the setting and make reference setup on your actual joint.
see Service Instructions.
Test method - Static or Dynamic
A static torque measurement is recommended for the ErgoPulse machines.
If dynamic torque measurement with an electronic inline torque transducer is used, always verify your measurement result by a static check with a torque wrench (electronic).
For more information, read Atlas Copco "Pocket Guide to Pulse Tools". Ordering No. 9833 1225 01.
Maintenance
For maximum performance
At tough working conditions – soft joints and max. setting – lubrication of the air is recommended.
With extreme dry air the service life of vanes and machine performance might be reduced. A daily supply of 0.1 – 0.2 ml oil into the machine inlet will improve the machine performance. Alternatively consider an automatic lubricator device, Atlas Copco oil fog lubricator DIM, or single point lubricator DOS, which will improve the machine performance.
Refill the pulse-unit with oil
For further information pls see - Service Instructions.
For optimum machine performance the pulse unit must be correctly filled with oil. Due to a possible microleakage of oil from the pulse unit, it could be necessary to refill the unit between the regular overhaul intervals. The frequency of this procedure depends on the type of application, number of cycles, tightening time etc. An accurate refill of the pulse unit gives long service intervals.
Too much oil in the pulse unit implies a low pulse frequency and slow tightening.
Too little oil in the pulse unit implies a high pulse frequency and there will be a risk of a decreasing tightening torque. In particular at the first tightening after a break the machine might race.
Use Hydraulic Oil : 22 cST / 40 °C (ISO VG22).
Running the machine with too little oil may damage the pulse unit.
After the refill – Check the tightening torque, see Service instructions.
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles cause rust and sticking of vanes, valves etc. An air filter should be installed close to the machine (se 'Air quality'). Before longer standstills, flush with oil (some drops) into the air inlet, run the machine for 5-10 seconds when absorbing the oil in a cloth.
Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once per year or after maximum 250.000 tightening depending on which occurs sooner. More frequent overhaul may be needed, specially replacing of oil in the pulse unit, if used at high torque and long tightening times. If the machine is not working properly, it should immediately be taken away for inspection.
The strainer at the air inlet and the exhaust silencer should be cleaned frequently or replaced in order to prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accurately and defective or worn parts should be replaced.
All o-rings should be greased before assembling; especially important are the o-rings in the pulse unit.
Disassembling /assembling
It is important that the machines threaded connections are tightened properly; i.e. in accordance with the specifications on the exploded views.
Cleaning
Clean all parts, not electrical, thoroughly in white spirit or similar cleaning agent. To prevent clogging and decreased power, it could be necessary to clean the strainer (if used) and the exhaust filter between the overhauls.
Inspection
After the cleaning, inspect all parts. Damaged and worn parts should be replaced.
Lubrication
Lubricate specially gears, valve and clutch with grease containing molybdenum disulphide (e.g. Molykote BR2 Plus). Lubricate o-rings and threaded connections with grease before assembling.

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 workstation 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 tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool 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.
Select the appropriate tool for the work task.
Use ear protection equipment in noisy environments.
Use high-quality inserted tools or consumables to minimize exposure to excessive levels of vibration.
Minimize exposure to reaction forces.
When cutting:
A cut-off wheel can get stuck if the wheel is either bent or if it is not guided properly. Make sure to use the correct flanges for cut-off wheels and avoid bending the wheel during cut-off operation.
When drilling:
The drill might stall when the drill bit breaks through. Makes sure you use support handles if the stall torque is too high. The safety standard ISO11148 part 3 recommends using something to absorb the reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
When using direct-driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The ability to bear reaction forces depends on the operator’s strength and posture. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.
Use dust extraction system or mouth protection mask in dusty environments.

How to optimize the performance of your EP/EPP tool
How to optimize the performance of your EP/EPP 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 can be measured with a IRTT and ACTA analyser.
The tightening time can also be used as a guide
to know if the tool is appropriate or not for your application:
≤ 1 sec. for tools up to 30Nm
≈1 sec. for tools up to 80Nm
≈2 sec. for tools up to 150Nm
≈5 sec. for tools up to 450Nm
≤ 10 sec. for tools up to 850Nm
If the target torque is achieved with less than 5 pulses (=short tightening time), the torque scatter will increase and it can be difficult to adjust to the right level, especially on hard joints.
If the target torque is achived with more than 20 pulses (=too long tightening time) the wear will increase 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 condition the power will decrease with even longer tightening time and perhaps no shut off.
If the target torque is achieved with less than 5 pulses adress this issue by:
Decreasing the air pressure.
Reducing the speed by means of the AT or Trim valve.
If these measures are not possible or does not give acceptable results, a smaller tool can be a better choice.
If the target torque is achieved with more than 20 pulses adress this issue by:
Increasing the dynamic air pressure to 6-7 bar for standard EP tools or 5-6 bar for low pressure EP PTX-L tools.
Adjust the AT or Trim valve to give maximum power/speed.
If these measures are not possible or does not give acceptable results, a bigger tool can be a better choice.
If the air pressure has been changed the target torque must be measured again and adjusted if needed.
Air preparation
Air pressure
Adjusting the air pressure will have the following consequences:
Decreasing the air pressure will result in a slower but more accurate tool.
Increasing the air pressure will result in a faster but less accurate tool.
If the pressure from the airline is below 4.5 bar we recommend a tool from the EP PTX-L series, designed for low pressure installations.
Pressure regulators
We recommend using one pressure regulator for each tool. Make sure
to adjust the regulator to the lowest expected pressure on the line.
A pressure regulator will give the following advantages:
A stable air pressure which results in better accuracy.
Provides an easy way to adjust the power of the tool.
Air filters and air lubricators
We recommend using air filters and air lubricators, which will give
the following advantages:
Clean air without water and particles resulting in reduced tool wear and reduced risk of tool failure.
Will help to maintain the power and speed of the air motor over time.
Trim-RE or AutoTrim valve?
Use Trim-RE valve:
For applications where the tool is used to tighten screws with similar joint rate.
Use AutoTrim valve:
For applications where the tool is used to tighten both hard and soft joints.
Adjusting the AutoTrim valve
When using a tool with a AutoTrim valve make sure it is correctly adjusted, so the switching to full power is produced after the rundown and when the pulsing is starting.
For detailed instructions on how to adjust the AutoTrim valve see section Settings
Incorrect adjustment of the AutoTrim valve will result in:
Increased scatter.
Longer tightening time.
No shut off.
Service tools
Service tools are designed to make assembly and disassembly fast and easy with less risk of damaging parts in the process.
Correct tightening of parts is important to:
Optimize performance of the tool.
Minimize the risk of parts coming loose during operation.
You can find information about service tools and tightening data in the Spare part list section of the Product instruction.
Preventive maintenance
Preventive maintenance is recommended once per year or after a maximum of 250.000 tightening. A complete overhaul include:
Clean the pulse unit and change worn or damaged parts.
Clean the air motor and change worn or damaged parts.
Clean the silencer and the strainer of the inlet adapter, change the filter and change worn or damaged parts.
Clean the trigger and reversing valve and change worn or damaged parts.
General
Tightening of threaded connections
The tightening torques indicated in the exploded views list are established to achieve the correct clamping force and preventing the parts from coming loose. At service these parts must be able to open up without being destroyed. In special circumstances (depending on application and usage) the parts may however come loose after some time of operation. In such cases the torque could be increased 10-20% and if necessary some type of low or medium threadlocking fluid could also be applied.
Example
Operating Instructions
Inspection and lubrication of pulse unit
Fill the pulse unit with oil on a regular basis
It is necessary to fill the pulse unit with oil on a regular basis to compensate for micro leakage of oil between the outgoing shaft and the sealing o-ring. This is a normal occurence in hydraulic systems. Between overhauls regularly fill up the pulse unit with a small amount of oil without disassembling the pulse unit. The need for adding oil to the pulse unit will vary depending mainly on the number of tightening, torque level and number of pulses (tightening time). The need to add oil regularly to the pulse unit will normally decrease because the o-ring will seal better after a period of use. When the o-ring is changed the need to add oil regularly to the pulse unit may increase again.
Do not change the o-rings in the pulse unit except at the regular overhaul once per year or after a maximum of 250.000 tightening.
Negative effects of to little oil in the pulse unit:
Longer tightening time
No shut off
Decreasing torque
Increased scatter
Faster wear of the parts in the pulse unit
How to detect a low oil level in the pulse unit:
Increased pulse frequency
Low torque, no torque or abnormal torque changes
Very high pulsing speed, especially when the tool has not been used for a while.
Regular measurement of the pulse frequency is the best method to detect a low oil level in the pulse unit. If the pulse frequency has increased, preventive oil filling can be done before a low oil level in the pulse unit affects the function of the tool. The pulse frequency can be measured with a static torque transducer (SRTT) or an inline transducer (IRTT) connected to an ACTA 4000 instrument.
Recommended oil for the pulse unit
Recommended oil for the pulse unit:
SE2 Lubricant 45
Other hydraulic oils can also be used if they have the following characteristics: 22 cST/40ºC (ISO VG22). For example Mobil DTE-12M or Pennzoil Pennzbell AW22.
A bottle of SE2 Lubricant 45 oil and the required syringe or syringes are orderable as kits. Please see Service Kits for ordering numbers.
How to fill the pulse unit with oil
Method 1 (when using an ACTA and a Transducer):
This method is the fastest and will also give an optimized tool performance and result in the longest filling intervals. Fill the pulse unit with oil in accordance with the following instructions:
Position the pulse unit in a vice. Remove the oil plug positioned on either the front or the back of the pulse unit. Add a small amount of oil to the pulse unit.
Assemble the tool and measure the pulse frequency, for more details on measuring the pulse frequency see Static measurement with fixed transducer.
If the pulse unit frequency is in the specified range the amount of oil is correct.
If the pulse unit frequency is to low reduce some oil and measure the pulse frequency again.
If the pulse frequency is to high add some oil and measure the pulse frequency again.

Method 2 (whitout an ACTA and Transducer):
This method is not as fast and accurate as using method 1. Fill the pulse unit with oil in accordance with the following instructions:
Position the pulse unit in a vice. Remove the oil plug positioned on either the front or the back of the pulse unit. Fill the pulse unit to 100% full. Assemble the oil plug.
Assemble the tool and run in reverse for 3-5 seconds.
Position the pulse unit in a vice. Remove the oil plug. Wait for all air bubbles to dissapear (approximatley 15 minutes) and the temperature to drop down to 20 degrees.
Fill the pulse unit to 100% full.
Reduce the oil in the pulse unit with a specified volume according to table using a 1 ml syringe. Assemble the oil plug.

Position of stop pin
The “X” measurement is correctly set at our factory before delivery. Normaly the “X” measurement has to be adjusted only after that the parts concerned have been dismantled. If the accuracy is not as good as expected, check the position of the stop pin. The position of the stop pin is adjusted by turning the screw (see fig. below).
To ensure that the adjustment screw not will change position during operation, must the screw be sealed with "Loctite 290". Apply the "Loctite" before the adjustment is started.
The measurement “X” is hard to measure. It is possible to get the position by starting from “X” = zero. Hold the pulse unit vertically and check that the stop pin is covering a part of the centre hole (i.e. “X” is more than zero). Arrange the shut off valve in the centre hole (see fig. below). Adjust the screw until the valve drops down in the hole of the stop pin. In this position “X” is zero.
Place a gauge (i.e. a drill bit) with a diameter “D” according to table below in the hole. Then unscrew the screw untill the gauge is just tight in the hole. Note: the gauge must not be squeezed by the stop pin. Another way to get an appropriate “X” measurement is to unscrew the screw from the position “X” = zero. Unscrew the No. of turns given in the table below. The measurements given in the table will give a basic adjustment. Check the diameter “D” with a drill bit or similar. An increased “X” means a higher tightening torque and a decreased “X” means a lower tightening torque. It is possible to fine-adjust the tightening torque by turning the screw. Change with an 1/8 of a turn at a time.
