Noise and vibration
The measured values were defined according to
EN60 745.
Typical A-weighted noise level of the power tool:
Sound pressure level L
p
A=88,7 dB(A)
Noise level LwA=99,7 dB(A)
Measurement uncertainty K=3 dB (A)
Wear personal hearing protection!
Vibration total values (vector sum of three directions)
calculated according to EN 60745:
Surface grinding (rough grinding):
Vibration emission level ah,AG=8,81

Vibration values stated in these instructions were
measured in accordance with the standardized method
of measurement according to EN 607 45 and they can be
used for the comparison of power tools. The method is
also suitable for a provisional assessment of vibration
load.
The indicated vibration level presents the main intended
use of the power tool. However, if the power tool is used
with a different accessory for other purposes, for ex.
cutting, brushing etc., or if it is insufficiently maintained,
the vibration level can deviate. This can increase
vibration load significantly during certain periods of use.
For an accurate assessment of vibration load during a
defined time period, we should also consider periods
when the power tool was switched off or it was
functioning, but not used. This could significantly reduce
data on vibration load during the entire time of work.
Define additional safety precautions to protect the tool
user from vibration impact, for ex. maintenance of the
power tool and its accessories, warming of hands,
organization of progress of work.
Description of electronic versions of diamond
grinder HJ2304
Soft start
allows the working speed to be reached
without provoking a reacting torque on starting the
machine, and the maximum speed is achieved after two
seconds. You can start working after that time.
Constant electronic speed adjustment,
holds the
speed between no-load and working load nearly
constant.
At short high overloading or long low overloading of the
tool, the built in overload protection electronics limits the
@
tool's operation, which turns very slowly when the load is
removed or it stops, if it is loaded again.
By switching it off and repeating the starting
procedure the tool will work normally.
Frequent operation of overload protection signifies that
the tool is excessively overloaded and the motor can be
damaged or its service life will be shortened. Besides,
excessive overloading will not improve either the speed
or the quality of the work.
We recommend you not to overload the tool in order the
overload protection will not switch off the tool; this way
you will protect the tool and the tool's performance will be
higher as grinding discs will be less worn out. We advise
you to cool down the tool under no load for at least
one minute in case of several successive limiting
functions.

PREPARING THE TOOL F0R WORK
&
Always disconnect the plug from power
source before making any adjustments or
changing any accessory!
Mounting the auxiliary handle to the tool - Figure 1
Place the front handle
@
to the desired position
(depending on work) and tighten the screws G). The
handle can be staged at 30 °, adjust work.
