Problem Cause
Excessive wear of the piston tip
Spline breakage Lack of lubrication
Dirt intrusion (specially when drilling
upwards)
Piston breakage Lack of lubrication
Uneven tension in the side bolts
Worn intermediate part/piston guide (can
be confirmed by the cushion test)
Side bolt breakage Uneven tension on the bolts

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.
