Metabo PowerMaxx SSD Manual Original página 11

The screwdriving process has two elements:
inserting the screw and
tightening the screw with the percussion
mechanism.
The tightening torque depends on the impact
duration.
With an impact duration of approx. 5 seconds, the
maximum tightening torque has been reached.
The torque curve depends on the type of
application:
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 (5), ensuring that the screw is
not damaged or that the screw head does not tear
off.
8. Accessories
Use only genuine Metabo accessories.
For dealers to select the correct accessory, they
need to know the exact model designation of your
tool.

9. Repairs
Repairs to electrical tools must be carried out
by qualified electricians ONLY!
If you have Metabo electrical tools that require
repairs, please contact your Metabo service centre.
For addresses see www.metabo.com.
You can download spare parts lists from
www.metabo.com.
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
Metabo dealer!
Do not allow battery packs to come into contact with
water!
To protect the environment, do not dispose of
power tools or battery packs in household
waste. Observe national regulations on
separated collection and recycling of disused
machines, packaging and accessories.
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).

The vibration emission level given in this
information 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 is also suitable for a provisional estimate
of the vibratory load.
The specified vibration level applies to the main
applications of the power tool. However if the tool is
used for different applications, with different
accessories or poorly maintained, the vibration
emission may differ. This can considerably increase
the vibratory load over the entire 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.
