for drilling holes in these materials. Cordless, battery-powered power tools are especially useful for works
in interior furnishing, adaptation of premises etc.
Use the power tool according to the manufacturer's instructions only.
3. Noise level and vibration parameters.
Sound pressure: Lp
Sound power: Lw
Vibration acceleration: a
4. Battery and charger information.
The cordless drill is not supplied with battery and charger. Use only battery and charger from series
R20 System.
5. Operation and settings. Switching on. Switching off.
5.1. Switching on - press the switch button (1).
5.2. Switching off - release the switch button (1).
5.3. Spindle brake.
Drill is equipped with electronic brake, which stops the spindle immediately after the switch (6) is
released. The brake ensures precision when screwing or drilling and prevents free spindle rotation after
it is switched off.
5.4. Rotational speed control.
Screwing or drilling speed can be controlled during operation by increasing or decreasing pressure on
the switch button (1). Speed control enables soft start, which prevents drill slip when drilling in gypsum or
glaze and helps to control the operation when screwing and unscrewing.
5.5. Overload clutch. Torque control.
Setting the ring (3) in given position causes permanent setting of the clutch to specified torque. When
the set torque is reached, overload clutch releases automatically. It prevents screwing screws t deep or
damaging the drill.
Different screws and materials require different torque to be applied.
The bigger number corresponding to given position, the bigger the torque.
Set the ring (3) to specified torque.
Always start operation with low torque.
Increase the torque gradually until appropriate value is set.
Use higher settings to unscrew screws.
When drilling chooses settings marked with the drill symbol. When this setting is set, the torque is the
greatest.
Knowledge how to choose appropriate settings comes with practice.
Setting the ring in the drilling position deactivates the overload clutch.
5.6. Change of gear.
Drill features gear switch , which broadens the range of rotational speed.
Gear I: small speed range, big torque;
Gear II: big speed range, low torque.
Set the switch in appropriate position depending on the works performed. Turn the spindle slightly if
the switch cannot be moved.
Never change the switch position under operation of the drill. It may damage the power tool.
5.7. Working tool installation.
Set the direction selector switch in middle position.
By holding the rear ring of the chuck and turning the front ring clockwise, you can set required jaw
spread and insert appropriate drill or driver bit.
Drill or driver bit must be pushed to the chuck limit.
Hold the rear ring and turn the front ring counter-clockwise, tighten hardly.
Deinstallation of the tool is similar to installation, only the sequence of actions is reversed.
Check position of the tool when installing drill or driver bit in the chuck. Use additional magnetic
adaptor as an extension when using short driver bits.
5.8. Left - right direction of rotation.
