Insert key into one of the holes on the circumference of the drill chuck (1).
Open jaws to desired dimension.
Insert cylindrical drill shank into the drill chuck (1), push it to the limit.
Tighten jaws on drill shank with the key (insert it into three holes on the drill chuck circumference).

Remember to always remove the key from the chuck, after you finish drill installation or removal.

OPERATION / SETTINGS

SWITCHING ON / SWITCHING OFF
The mains voltage must match the voltage on the label of the drill.
Switching on – press the switch button (6) and hold in this position.
Switching off – release pressure on the switch (6).
Locking the switch (continuous operation)

Switching on:

Press the switch button (6) and hold in this position.
Press the switch lock button (3) (fig. A).
Release pressure on the switch button (6).

Switching off:

Press and release the switch button (6)

Range of rotational speed of the spindle is controlled with pressure on the switch button.

WHEEL FOR SPINDLE SPEED ADJUSTMENT
The drill allows for operation with different spindle speeds. It can be controlled with the wheel (5) (fig. A). For each setting of the wheel for speed control, the speed can be adjusted continuously by increasing or decreasing pressure on the switch button (6).

Increase the speed by turning the wheel (5) clockwise.
Reduce the speed by turning the wheel (5) counter clockwise.
Refer to graphic symbols on the wheel for rotational speed control or the switch.

Choose proper rotational speed when the drill operates with no load, with pressed switch lock button. Defined speed may decrease under load.

LEFT – RIGHT DIRECTION OF ROTATION
Choose direction of spindle rotation with the selector switch (4) (fig. A).
Clockwise rotation – set the switch (4) to the extreme left position.
Counter clockwise rotation – set the switch (4) to the extreme right position.

In certain cases position of the direction selector switch relating to rotation direction may be different than specified. Please refer to graphic signs placed on the switch or tool body.

Do not change direction of rotation when the spindle of the drill is rotating. Ensure the position of the direction selector switch is correct before starting the tool.

OPERATION MODE SWITCH
Operation mode switch (2) allows for choosing suitable work mode: drilling with or without impact (fig. B). Set the operation mode switch in the position for drilling without impact (drill symbol), when processing materials like metal, wood, ceramics, plastics and alike. Set the operation mode switch in the position for drilling with impact (hammer symbol), when processing materials like stone, concrete, brick and alike. Holes in wood, wood based materials and metals can be made with drills of high speed steel or carbon steel (the latter for wood and wood based materials only). For impact drilling special drills with sintered carbide inserts should be used.

You should not use counter clockwise rotation when impact function is on.

Long lasting drilling at low rotational speed of the spindle may cause motor overheating. Provide regular breaks during operation or let the tool operate at maximum speed with no load for approximately 1–2 minutes. Do not cover holes for motor ventilation in the tool body.

NOISE LEVEL AND VIBRATION PARAMETERS

Noise and vibration information.
Parameters of produced noise level, such as sound pressure level LpA and sound power level LwA with measurement uncertainty K are specified below in this manual, in accordance with EN 60745. Vibration values ah and measurement uncertainty K are determined in accordance with EN 60745-2-1 and specified below. Vibration level specified below in this manual was measured in accordance with measurement procedure defined in EN 60745-2-1 and can be used to compare power tools. It can also be used for initial assessment of exposure to vibrations. Specified vibration level is representative for main applications of the power tool. Vibration level may change if the power tool is used for other purposes, with different working tools or will not be maintained properly. The abovementioned factors may lead to higher exposure to vibrations during whole working time. To precisely define exposure to vibrations, include periods when the power tool is switched off and when it is switched on but not used for working. This way total exposure to vibrations may be significantly lower. Use additional safety measures to protect the user against results of vibration exposure, such as: power tool and working tool maintenance, proper hand temperature conditions, good work organisation.
Sound pressure level: LpA = 93 dB(A) K=3dB(A)
Sound power level: LwA = 104 dB(A) K=3dB(A)

Vibration acceleration, impact drilling in concrete:
ah,ID = 8,41 m/s2 K=1,5 m/s2
Vibration acceleration, drilling in metal:
ah,D = 2,73 m/s2 K=1,5 m/s2
