with both hands using the handles provided,
stand in a safe position and concentrate.
7.6 Metabo VibraTech (MVT)
For reduced vibrations and less stress on the
hands.
Always apply a moderate amount of pressure to the
handle when pushing down the machine and do not
force. Vibrations are reduced most effectively at the
central position (7).
8. Cleaning, Maintenance
Motor cleaning: blow out the machine thoroughly at
regular intervals through the air slots with
compressed air.
9. Tips and Tricks
Only moderate pressure is required when working
with the machine. Applying excessive pressure
does not increase your working performance and
may decrease the service life of your machine.
In the case of deep bores, pull the drill bit out of the
bore from time to time in order to remove the stone
dust.
10. Troubleshooting
Carbon brush service indicator (10) 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 disturbance:
In individual cases, the speed may fluctuate
temporarily if the machine is exposed to extreme
external electromagnetic disturbances.
11. Accessories
Use only genuine Metabo accessories.
Use only accessories which fulfil the requirements
and specifications listed in these operating
instructions.
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 catalogue.
12. Repairs
Repairs to electrical tools must be carried out by
qualified electricians ONLY!
Contact your local Metabo representative if you
have Metabo power tools requiring repairs. For
addresses see www.metabo.com.
You can download a list of spare parts from
www.metabo.com.
13. Environmental Protection
Observe national regulations on environmentally
compatible disposal and on the recycling of disused
machines, packaging and accessories.
Only for EU countries: Never dispose of
power tools in your household waste! In
accordance with European Directive 2002/
96/EC on waste electrical and electronic equipment
and its implementation in national legal systems,
used power tools must be collected separately and
handed in for environmentally compatible recycling.

The technical specifications quoted are subject to
tolerances (in compliance with the relevant valid
standards).
Emission values
These values make it possible to assess the
emissions from the power tool and to compare
different power tools. Depending on the operating
conditions, the condition of the power tool or the
accessories, the actual load may be higher or lower.
For assessment purposes, please allow for breaks
and periods when the load is lower. Based on the
adjusted estimates, arrange protective measures
for the user e.g. organisational measures.
