Use dust masks. The use of dust masks reduces the risk of serious injury.
Hold the power tool by the insulated handles to avoid the risk when the bit attached comes into contact with a live con-
cealed wire when working. When the bit is in contact with a live wire it may cause the metal parts of the tool to become live,
which may give the user an electric shock.
PRODUCT OPERATION
Charging the battery (II)
Caution! Disconnect the charger from the mains before charging the battery. Also, remove any dirt and dust from the battery and
battery clamps with a soft and dry cloth.
Disconnect the battery from the tool by pressing the battery latch and sliding it out of the tool socket.
Insert the plug of the charger cable into the socket in the battery base and then plug the charger into a mains socket.
The LED next to the socket in the battery base will be illuminated. Red indicates charging and green indicates fi nished charging.
It is recommended to fi nish the charging process as soon as the green LED lights up. To do this, fi rst, unplug the charger from the
mains socket and then disconnect the charger cable plug from the battery socket.
Caution! It is forbidden to charge the battery when it is connected to the tool. In this confi guration, the tool is rendered inoperable.
The product is equipped with a battery charge indicator (IV), which provides an approximate indication of the battery charge level.
The indicator consists of status lights that illuminate when the product is turned on. The more status lights are on, the higher the
battery charge level.
Assembly of the bit in the tool chuck and disassembly
The product is equipped with a SDS Plus tool chuck, which cannot be removed.
The installation of a bit fi tted with a SDS Plus holder should be carried out as follows.
Thoroughly clean the bit SDS Plus holder and then cover it with a thin layer of general-purpose grease.
Insert the bit holder into the tool chuck so that the latch mechanism engages (III). Check that the bit will not slip out of the chuck.
It should be possible to move the bit forward–backwards within a small range but it should not be possible to remove the bit from
the chuck completely.
Disassembly of the bit should be carried out as follows. Pull the back part of the rotary hammer chuck in the product's handle
direction and hold it in this position. Slide out the bit from the chuck (IV).
Setting the operating mode (V)
The product has two operating modes i.e. drilling and hammer drilling. Switching between modes is done by changing the position
of the operating mode switch lever. The lever set on the drill bit symbol indicates drilling without hammering. Use this operating
mode for drilling, e.g. in metal or wood and some ceramic materials.
The lever set on the drill bit and hammer symbol indicates hammer drilling. Use this operating mode for drilling in hard ceramic
materials e.g. concrete. In this mode, the drill bit performs a reciprocating motion in addition to rotary motion.
Setting the rotation direction (IV)
Set the rotation direction switch to the position marked by the arrows shown on the switch. The direction of the arrow indicated a drilling di-
rection using a right-hand drill bit – the most popular one. Caution! The direction of rotation can only be changed when the spindle is stopped.
Preparatory actions for operation
Before starting work:
Fasten the workpiece to the vice or using G clamps.
Use working tools appropriate for the work to be carried out. Make sure that they are sharpened and in good condition.
Wear work clothing and eye and hearing protection equipment.
Install the battery in the product.
Grasp the rotary hammer with both hands by the handle and the additional handle (VIII).
Adopt a fi rm and stable posture.
Turn on the rotary hammer by pressing the electric power switch with your fi nger. The harder the power switch is pressed, the
higher the rotational speed of the drill bit and the higher the impact speed.
Caution! If suspicious noises, cracks, suspicious smell etc. are observed, immediately turn off the tool and remove the battery
from the device.
The rotary hammer is turned off by completely releasing pressure on the power switch. The bit may be still spinning for some time
after turning off the product. The product can only be put away or other product-related activities can be carried out once the bit
has completely stopped.
