The product is state of the art and complies with the associated technical safety requirements. Never-
theless, a low level of residual risks cannot be ruled out. Please observe the safety instructions to this
end.
All serious incidents occurring in relation to the device must be reported to the manufacturer and to the
competent authority of the Member State where the user and/or occupant is established.
WARNING
Failure to observe this user manual, in particular the safety instructions can lead to defects in the

It is not made exclusively of ame retardant materials. Keep the V-MAX2away from sources of igni-
tion.
The V-MAX2 may interfere with highly sensitive electromagnetic elds of other electronic devices
(e.g. anti-theft devices).
Stability tests were performed under laboratory conditions. The V-MAX2 may behave di󰀨erently under
real conditions compared to laboratory tests.
Training may only be carried out by the manufacturer, the AAT eld sta󰀨 or the qualied specialist shop.
Do not operate the V-MAX2with the drive shafts retracted as this may damage the device.
CAUTION
External heat sources may cause the surface temperature to rise (e.g. sunlight)!
