NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardised
test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary asses-
sment of exposure. The declared vibration emission level represents the main applications of the tool. However if
the tool is used for different applications, with different accessories or poorly maintained, the vibration emission
may differ. This may significantly increase the exposure level over the total working period. An estimation of the
level of exposure to vibration should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working peri-
od. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the
tool and the accessories, keep the hands warm, organisation of work patterns.
●
The tool must not be changed, modified or manipu-
lated in any way other than as described in the operat-
ing instructions.
●
To avoid the risk of injury, always use only original
Hilti accessories.
●
Do not operate the tool without a suitable dust extrac-
tion system. The safety and disposal regulations must
be observed particularly when sanding materials which
present a health hazard (e.g. oak or beech wood, paint
containing lead or other harmful substances).
Observe the information given in the operating instruc-
tions concerning operation, care and maintenance.
