does not increase your working performance and
may decrease the service life of your machine.
KHE 56: in the case of deep bores, pull the drill bit
out of the bore from time to time in order to remove
dust.

11 Troubleshooting

Carbon brush service indicator (13) lights up:
the carbon brushes are almost completely worn
(remaining operating time approx. 30 hours). If the
brushes are completely worn, the machine
switches off automatically. Have an authorised
service centre replace the brushes.
Electromagnetic disturbances:
In individual cases, the speed may fluctuate
temporarily if the machine is exposed to extreme
external electromagnetic disturbances.
12 Accessories
Use only genuine Metabo accessories.
If you need any accessories, check with your
dealer.
For dealers to select the correct accessory, they
need to know the exact model designation of your
power tool.
See page 4.
A Extensive drill bit and chisel assortment for a
wide range of applications.
B Special grease (for lubricating the tool shanks)
For a complete range of accessories, see
www.metabo.com or the main catalogue.
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 enclose a description of the fault with the
power tool.

14 Environmental Protection

Metabo's packaging can be 100% recycled.
Scrap power tools and accessories contain large
amounts of valuable resources and plastics that

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.

WARNING
The vibration emission level given in this informa-
tion sheet has been measured in accordance with
a standardized test given in EN 60745 and may
be used to compare one tool with another.
The vibration emission level will vary because
of the ways in which a power tool can be used
and may increase above the level given in this
information sheet. This could lead to a significant
underestimate of exposure when the tool is used
regularly in such a way.
Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given
period of work should also take into account the
times when the tool is switched off and when it is
running but not actually doing the job. This may
significantly reduce the exposure level over the
total working period.
