Overview
To reduce the risk of serious injury or death to yourself or others, read the Safety instructions section found on the previous pages of this manual before operating the machine.
Design and function
RTEX is a range of hand-held, pneumatic breakers designed for medium to heavy demolition of materials such as concrete, asphalt and brickwork.
The pneumatic breakers are designed for vertical use. No other use is permitted.
Recommended working tools are listed in the spare parts list.
Choosing the correct breaker for a task
•
•
It is important to choose the correct size of breaker for the work to be performed.
A breaker that is too small means that the work will take longer.
A breaker that is too large means that there must be frequent repositioning, which is unnecessarily tiring for the operator.
A simple rule for choosing the correct size of breaker is that a normal sized piece of broken material should be removed from the workpiece within 10–20 seconds operation.
If it takes less than 10 seconds a smaller breaker should be selected.
If it takes more than 20 seconds a larger breaker should be selected.

◆ Check that you are using the correct recommended operating pressure, 6 bar (e) (87 psi).
◆ The maximum permissible air pressure, 7 bar
(e) (102 psi), must not be exceeded.
◆ Blow any impurities out of the compressed air hose before connecting it to the machine.
◆ Select the correct dimension and length for the compressed air hose. For hose lengths up to 30 m (100 ft), a hose with a minimum internal diameter of 19 mm (¾ in.) must be used. If the hose length is between 30 and 100 m (100 and
330 ft), a hose with a minimum internal diameter of 25 mm (1 in.) must be used.
Methods to prevent freezing
Ice formation in the silencer can occur when the ambient air temperature is 0-10°C (32-50°F) and the relative humidity is high.
The machine is designed to avoid the formation of ice in the silencer. Despite this, under extreme conditions ice can form in the silencer.
The following actions can be taken to further counteract the risk of ice formation:
◆ Use Atlas Copco Breaker and hammer AIR-OIL as a lubricant. Atlas Copco Breaker and hammer AIR-OIL counteracts freezing.
◆ Use a water separator.
Connecting a water separator
The length of the air hose between the compressor and the water separator must be such that the
© Construction Tools PC AB | 9800 1724 01 | 2017-05-31
Original instructions
RTEX water vapor is cooled and condenses in the hose before reaching the water separator.
If the ambient temperature is below 0°C (32°F) the hose must be short enough to prevent the water from freezing before reaching the water separator.
Lubrication
The lubricant is important for the machine’s function and has a great impact on the service life.
In order to supply the correct volume of oil, an lubricator should be connected to the air hose. The use of a Atlas Copco air line lubricator is recommended. To guarantee good lubrication, the length of the air hose between the oiler and the pneumatic tool should not exceed 3 m (10 feet).
Too much lubrication can cause starting problems, low power or uneven performance.
Use a synthetic lubricant such as Atlas Copco
Breaker and hammer AIR-OIL or mineral oil with the properties recommended in the table below.

◆ After each service, check that the machine's vibration level is normal. If not, contact the nearest authorised workshop.
Every day
Before undertaking any maintenance or changing the insertion tool on pneumatic machines, always switch off the air supply and bleed the machine by depressing the start and stop device. Then disconnect the air hose from the machine.
◆ Clean and inspect the machine and its functions each day before the work commences.
◆ Check the tool retainer for wear and function.

Conduct a general inspection for leaks and damage. Pay extra attention to leaks around the Top cover. Ensure there is no air leaks around the top cover, if so immediate action must be taken to rectify before use.
Check that the air inlet nipple is tightened and that the claw coupling is free from damage.
Check regularly that the oil plug is tightened.
Check that the O-ring on the oil plug is undamaged and that it closes tightly.
Check the threads in the machine lubricator and on the oil plug. Make sure they are not damaged or worn out.
Too big clearance between the insertion tool’s shank and the chisel bushing will generate increased vibrations. To avoid getting exposed to excessive vibrations, check the chisel bushing for wear using the gauge that corresponds to the insertion tool’s shank dimension. If it is possible to push the gauge
(point A) fully into the chisel bushing (to point B) then immediately replace the chisel bushing.
See also “Checking for wear on the tool shank” for checking the insertion tool’s shank.

Change damaged parts immediately.
Replace worn components in good time.
Make sure that all the attached and related equipment, such as hoses, water separators and lubricators are properly maintained.
Periodic maintenance
After each operating period of approximately 150 impact hours or twice a year the machine must be dismantled and all parts be cleaned and checked.
This work must be performed by authorised staff who are trained for this task.

Troubleshooting
If the pneumatic machine does not start, has low power or uneven performance, check the following points.
◆ Check that the working tool being used has the correct shank dimension.
◆ Check that the pneumatic machine is getting the correct amount of lubricant. Too much lubrication can cause starting problems, low power or uneven performance.
◆ Check that the compressed air system supplies the machine with sufficient air pressure to give full power.
◆ Check that the dimension and length of the air hose are according to the recommendations.
See “Installation”.
◆ If there is a risk of freezing, check that the machine's exhaust ports are not blocked.
◆ If the machine function is still not satisfactory after this procedure, contact an authorised service workshop.

Noise and vibration declaration statement
Guaranteed sound power level Lw according to EN ISO 3744 in accordance with directive 2000/14/EC.
Sound pressure level Lp according to EN ISO 11203.
Vibration value A and uncertainty B determined according to EN ISO 28927-10. See table ”Noise and vibration data” for the values of A, B, etc.
These declared values were obtained by laboratory type testing in accordance with the stated directive or standards and are suitable for comparison with the declared values of other tools tested in accordance with the same directive or standards. These declared values are not suitable for use in risk assessments and values measured in individual work places may be higher. The actual exposure values and risk of harm experienced by an individual user are unique and depend upon the way the user works, in what material the machine is used, as well as upon the exposure time and the physical condition of the user, and the condition of the machine.
We, Construction Tools PC AB, cannot be held liable for the consequences of using the declared values, instead of values reflecting the actual exposure, in an individual risk assessment in a work place situation over which we have no control.
This tool may cause hand-arm vibration syndrome if its use is not adequately managed. An EU guide to managing hand-arm vibration can be found at http://www.humanvibration.com/humanvibration/EU/
VIBGUIDE.html
We recommend a programme of health surveillance to detect early symptoms which may relate to vibration exposure, so that management procedures can be modified to help prevent future impairment.
