13 Repairs
Repairs to electrical tools must be carried out by
qualified electricians ONLY!
Any Metabo power tool in need of repair can be
sent to one of the addresses listed in the spare
parts list.
Please attach a description of the fault to the
power tool.
14 Environmetal Protection
Metabo's packaging can be 100% recycled.
Worn out power tools and accessories contain
considerable amounts of valuable raw and plastic
materials, which can be recycled.
These instructions are printed on chlorine-free
bleached paper.
Only for EU countries: Never dispose of
power tools in your household waste! In
accordance with European Guideline
2002/96/EC on used electronic and electric
equipment and its implementation in national
legal systems, used power tools must be collected
separately and handed in for environmentally
compatible recycling.

EN 60745:
a = Vibration emission value

(chiselling)
K = Unsafe (vibration)
h,HD/Cheq
The vibration emission level given in this informa-
tion 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 assessment 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
period.
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.
