8.7. Protect the lithium-ion battery from frost. Rechargeable batteries that are stored below 0 ֯ C for
more than 60 minutes should be discarded.
8.8. When handling batteries, be aware of the electrostatic charge. Electrostatic discharges cause
damage to the electronic protection system and battery cells. Beware of the electrostatic charge and
never touch the battery poles.
9. Operation and settings. Switching on. Switching off.
9.1. Switching on - press the switch button (1).
9.2. Switching off - release the switch button (1).
9.3. Spindle brake.
Drill is equipped with electronic brake, which stops the spindle immediately after the switch is
released. The brake ensures precision when screwing or drilling and prevents free spindle rotation after
it is switched off.
9.4. Rotational speed control.
Screwing or drilling speed can be controlled during operation by increasing or decreasing pressure
on the switch button. 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.
9.5. Overload clutch. Torque control.
Setting the ring 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 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.
9.6. 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.
9.7. 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.
9.8. Left - right direction of rotation.
Choose direction of spindle rotation with the selector switch
Right rotation - move the switch) to the extreme left position.
Left rotation - move the switch to the extreme right position.
Do not change direction of spindle when the spindle is rotating.
9.9. Drilling.
When you need to vent large diameter, is recommended first to break a small opening, which will
then be drilling to the desired size. This will prevent overloading the drill. Drilling deep holes should be
