The vibration values quoted above have been
measured according to a standardized test pro‐
cedure and may be used to compare electric
power tools.
Depending on the type of usage, the vibrations
that actually occur may differ from the values
quoted.
The vibration values quoted may be used for an
initial assessment of the user's exposure to
vibrations.
The actual exposure to vibrations has to be eval‐
uated. This process may also take into account
times during which the electric power tool is
switched off and times during which it is switched
on but running without load.
Observe measures to reduce vibration exposure
to protect the user – see section on "Vibrations"
in chapter on "Safety Precautions and Working
Techniques".
The K‑factor in accordance with Directive
2006/42/EC is 2.0 dB(A) for the sound pressure
level and sound power level; the K‑factor in
accordance with Directive 2006/42/EC is
2.0 m/s
2
for the vibration level.
21.6
Transporting
STIHL rechargeable batteries comply with the
requirements stipulated in UN‑Manual Tests and
Criteria, Part III, Subsection 38.3.
