ENGLISH
With an impact duration of approx. 5 seconds, the
maximum tightening torque has been reached.
The torque curve depends on the type of applica-
tion:
With a hard screwdriving application (screw-
couplings in hard material such as metal), maximum
tightening torque is already reached after a short
impact duration (a).
With a soft screwdriving application (screw-
couplings in soft material such as wood), a longer
impact duration (b) is required.
Recommendation: determine the correct impact
duration by carrying out trial screwdriving.
Caution! With small screws, maximum torque can
be reached even below an impact duration of 0.5
seconds.
- This is why the duration of the screwdriving
process must be monitored exactly.
- Adjust the tightening torque by pressing firmly or
lightly on the trigger (3), ensuring that the screw is
not damaged or that the screw head does not tear
off.
8. Accessories
Use only genuine fischer accessories.
Use only accessories that fulfil the requirements
and specifications listed in these operating instruc-
tions.
See page 4.

9. Repairs
Repairs to electrical tools must be carried out
by qualified electricians ONLY!
If you have fischer electrical tools that require
repairs, please contact your fischer service centre.

10. Environmental Protection
Observe national regulations on environmentally
compatible disposal and on the recycling of disused
machines, packaging and accessories.
Battery packs must not be disposed of with regular
waste. Return faulty or used battery packs to your
fischer dealer!
Do not allow battery packs to come into contact with
water!
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.
Before disposal, discharge the battery pack in the
power tool. Prevent the contacts from short-circu-
iting (e. g. by protecting them with adhesive tape).

Measured values determined in conformity with
EN 60745.
Direct current
The technical specifications quoted are subject to
tolerances (in compliance with the relevant valid
standards).
Emission values
Using these values, you can estimate the
emissions from this power tool and compare these
with the values emitted by other power tools. The
actual values may be higher or lower, depending on
the particular application and the condition of the
tool or power tool. In estimating the values, you
should also include work breaks and periods of low
use. Based on the estimated emission values,
specify protective measures for the user - for
example, any organisational steps that must be put
in place.
