Damaged power cables increase the risk of
electric shock.
Failure of the considered instructions may
lead to electric shock, fire and / or severe injuries.
6. Functional description and purpose of the
electric drill.
Power hand drills are in class II insulation. They
are powered by a collector single-phase motor,
the speed of revolutions is reduced by means
of gear. This kind of power is widely used for
boring holes in wood, dendroid materials, metal,
ceramics and synthetic materials in the working
mode without impact, as well as concrete, brick
and similar materials in the operating mode of
attack. Power electronic controls for right and
left direction of rotation can be used to develop
cornering or screw joints. The areas of use are
carrying out repair and construction, carpentry
and other work-related self-amateur activity.. Not
permitted the use of power tools for activities
other than its intended purpose.
7. Information on noise and vibration emitted
The values are measured according to EN
60745. A level of noise generated is generally:
the sound pressure level 81 dB (A); sound power
92 dB (A). Uncertainty K = 3 dB. Work with a
silencer! The resultant value of vibration (the
vector sum of the three directions) is determined
according to EN 60745: Drilling in metal: the
value of the emitted vibrations a
uncertainty K = 1,5 m/s
manual for the vibration value is measured by the
method specified in EN 60745 and can be used
to compare different power. The level of vibration
varies depending on the specific activity carried
out and in some cases may exceed that amount
in that direction. If power is used for a long
time in this mode, the load caused by vibration,
could be underestimated. Directions: For an
exact estimate of the burden of vibrations in
a working cycle should be recorded and the
intervals in which the power is off or idling. This
can significantly reduce the reporting burden of
vibrations throughout the business cycle.
8. Preparing for the job. Installation of
accessories and auxiliary tools.
8.1. Setting the depth of drilling. With deep
baffle can be pre-set depth of drilling. Pull the
baffle so deep that the distance along the axis
between the tip of the drill and deep baffle is
equal to the desired depth of the hole.
8.2. Placing the drill in the chuck. Turn off the
power of power. Put the key in one of the open side
= 5,83 m/s
h
. That in this operating
2
of the chuck. Dissolving the jaws to the desired
size and place in the drill chuck. With key-locking
in three successive drill a hole in the chuck. We
must always remember that the key should be
removed from the drill after the completion of
operations related to installation and dismantling
of the drill. When mounting a new drill should be
checked by the inclusion of a short drill, drill that
rotates in an axis without "flicker". This will help
us make sure that it is not distorted.
8.3. Inclusion and exclusion. Beware of the
voltage of supply network! Supply voltage of the
network must conform to the details shown on
the plate of power. Appliances marked with 230 V,
can be supplied with a voltage of 220 V.
8.4. To turn the drill press and hold the trigger
switch (1). For locking of the starting switch
pressed (1) press (2). Exclusion relax power
trigger switch (1), respectively, if anchored to
the button (2), first press the short term and then
release the trigger switch (1).
8.5. Adjust the speed of rotation. Drill allows to
work with different speed of spindle. Alignment
is done using the position. In the range of each
setting a speed can be adjusted smoothly by
increasing speed and reducing pressure on
the trigger button (1). Zavarteneto right speed
regulator leads to increase their rotation and left
to decrease.
8.6. Correct choice of the rate of speed shall
,
be held where drill is included without load. So

speed-minded when working with a load may be
lower.
8.7. Tools to develop or cornering.
Turntable working instrument can be bent.
After continuous operation with low-speed power
to cool as to leave it idling for approximately 3
minutes with a maximum speed of rotation.
When working with terminals must always use a
universal extension. Use only the cores that are
suitable for heads of screws. Turning to always
place the switch "drilling / hammer drilling» (6) in
position «Drilling».
8.8. Select the direction of rotation. With the
switch (4) you can change the direction of rotation
of power. Rotate right: For drilling and turning the
screw press to switch the direction of rotation (4)
at point blank range left. Rotate left: To develop
the screws and nuts, press switch direction of
rotation (4) right to the point blank range.
8.9. When you need to vent large diameter,
is recommended first to break a small opening,
which will then be drilling to the desired size. This
will prevent overloading the drill. Drilling deep
