DESCRIPTION
Impact drills are hand operated power tools with insulation class
II. Tools are driven by single-phase commutator motors with
rotational speed reduced with gear transmission. This type of power
tools is widely used for making holes in wood, wood-based
materials, metals, ceramics and plastics (no impact, rotation only
mode), and concrete, bricks and alike (with impact action). Range of
use covers repair and building works, woodworking and any work
from the scope of individual, amateur activities (tinkering).
Use the power tool in accordance with the manufacturer's
instructions only.

OPERATING
INSTALLATION OF ADDITIONAL HANDLE
Due to personal safety issues it is recommended to always use the
additional handle (7). Possibility to rotate the additional handle
before it is clamped on the drill body allows to choose the most
comfortable position for specific working conditions.
• Loosen the wheel lock that locks collar of the additional handle (7)
by turning it counter clockwise.
• Slide the additional handle (7) collar over cylindrical section of the
drill body.
• Turn for the most comfortable position.
• Turn the wheel lock of the additional handle (7) clockwise to clamp
the handle.
DEPTH GAUGE INSTALLATION
Depth gauge rod (8) is used to limit the depth of drill penetration in material.
• Loosen the wheel lock, which blocks collar of the additional handle
(7).
• Slide depth gauge rod (8) into the hole in the additional handle collar.
• Set desired drilling depth.
• Fix by tightening the wheel lock of the additional handle (7) collar.
INSTALLATION OF WORKING TOOLS
Disconnect the power tool from power supply.
• 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.
CHANGE OF GEAR
Drill is equipped with gear switch (9), which broadens the range of
rotational speed (fig. E).
Gear I: lower range of rotational speed – for large diameter holes or for
processing hard material.
Gear II: higher range of rotational speed – for small diameter holes or for
processing soft material.
Set the gear switch (9) in appropriate position depending on the processed
material. When the switch is blocked and cannot be moved, turn the
spindle slightly.
Never change position of the gear switch while the drill is operating.
It may damage the power tool.
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
