GRAPHITE 58G712 Übersetzung Der Originalanleitung Seite 8

The drill has a gear change switch (9) that allows you to increase the
speed range (Fig. C). Gear I: lower speed range – for drilling larger
diameter holes or working in hard material. Gear II: higher speed
range – for drilling smaller diameter holes or working in soft material.
Set the gear change switch (9) to the correct position for drilling,
depending on the material. If the switch cannot be moved, turn the
spindle slightly.
Never change the gear selector switch while the drill is running.
This could damage the power tool.
RIGHT-HAND/LEFT-HAND ROTATION
Use the rotation switch (4) to select the direction of rotation of the
drill spindle (Fig. A).
Right rotation – set the switch (4) to the extreme left position.
Counterclockwise rotation – set the switch (4) to the extreme right
position.
• Please note that in some cases the position of the switch in
relation to the rotation may be different than described. Please
refer to the symbols on the switch or on the device housing.
Do not change the direction of rotation while the drill spindle is
rotating. Before starting, check that the rotation direction switch
is in the correct position.
OPERATING MODE SWITCH
The operating mode switch (2) allows you to select the appropriate
operating mode: drilling without hammering or with hammering (Fig.
B). For drilling in materials such as metal, wood, ceramics, plastics
or similar, set the switch to the non-hammering position (drill
symbol). For drilling in materials such as stone, concrete, brick or
similar, set the switch to the impact mode (hammer symbol). Holes
in wood, wood-like materials and metals are made with high-speed
steel or carbon steel drill bits (only in wood and wood-like materials).
Special drill bits with carbide tips (widia) are used for hammer drilling.
Do not use the left-hand rotation direction when the hammer
function is activated.
DRILLING HOLES
• When starting work with the intention of drilling a large diameter
hole, it is recommended to start by drilling a smaller hole and then
reaming it to the desired size. This will prevent the drill from
overloading.
• When drilling deep holes, drill gradually, at smaller depths,
withdrawing the drill bit from the hole to allow chips or dust to be
removed from the hole.
• If the drill bit jams during drilling, switch off the drill immediately
to prevent damage. Use the change of rotation direction to
remove the drill bit from the hole.
• Keep the drill in line with the hole being drilled. Ideally, the drill bit
should be positioned at a right angle to the surface of the material
being worked on. If the drill bit is not perpendicular to the surface,
it may jam or break in the hole during operation, causing injury to
the user.
Prolonged drilling at low spindle speeds may cause the motor to
overheat. Take periodic breaks or allow the device to run at
maximum speed without load for approximately 3 minutes. Be
careful not to cover the holes in the housing used for ventilation
of the drill motor.
OPERATION AND MAINTENANCE
Before performing any installation, adjustment, repair or
maintenance work, remove the power cord plug from the mains
socket.
The hammer drill does not require any additional lubrication or
special maintenance. It does not contain any parts that require
maintenance by the user. Never use water or any chemical liquids
to clean the drill. Only wipe the device with a dry cloth. Always store
the drill in a dry place. Always ensure that the ventilation slots in the
drill housing are unobstructed. If the power cord is damaged, replace
it with a cord of the same specifications. This should be done by a
qualified specialist or by taking the drill to a service centre.
REPLACING THE DRILL CHUCK
• Open the jaws of the chuck (1).
• Remove the chuck fixing screw using a Phillips screwdriver,
turning the screwdriver clockwise (left-hand thread).
• Insert a hex key into the chuck (Fig. D).
• Tap the end of the hex key lightly.
• Unscrew the chuck.
Refit the holder in the reverse order to removal.
REPLACING CARBON BRUSHES
Worn (shorter than 5 mm), burnt or broken motor carbon brushes
must be replaced immediately. Always replace both brushes at
the same time.
The replacement of carbon brushes should only be carried out by
a qualified person using original parts.
Any faults should be repaired by an authorised manufacturer's
service centre.

Information on noise and vibration
The noise emitted by the device is described by: the emitted sound
pressure level Lp and the sound power level Lw
A
measurement uncertainty). The vibrations emitted by the device are
described by the vibration acceleration value a
measurement uncertainty).
The following values given in this manual: sound pressure level Lp
, sound power level Lw
A
measured in accordance with EN 62841-1. The specified vibration
level a( can be used to compare devices and for a preliminary
h)
assessment of vibration exposure.
The vibration level given is representative only for the basic
applications of the device. If the device is used for other applications
or with other working tools, the vibration level may change.
Insufficient or infrequent maintenance of the device will result in a
higher vibration level. The reasons given above may increase
exposure to vibration during the entire working period.
To accurately estimate vibration exposure, periods when the
device is switched off or when it is switched on but not used for
work must be taken into account. After careful estimation of all
factors, the total vibration exposure may be significantly lower.
In order to protect the user from the effects of vibration, additional
safety measures should be implemented, such as: regular
maintenance of the device and work tools, ensuring adequate hand
temperature and proper work organisation.
ENVIRONMENTAL PROTECTION
Electrically powered products should not be disposed of with
household waste, but should be taken to appropriate facilities for
disposal. Information on disposal can be obtained from the product
retailer or local authorities. Used electrical and electronic equipment
contains substances that are not environmentally neutral. Equipment
that is not recycled poses a potential threat to the environment and
human health.
