5.4. 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 (5), 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 (5) position under operation of the drill. It may damage the power tool.
5.7. Working tool installation.
Set the direction selector switch (2) in middle position.
Turning the front ring (4) counter-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.
Turn the ring (7) 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.
Choose direction of spindle rotation with the selector switch (2).
Right rotation - move the switch (2) to the extreme left position.
Left rotation - move the switch (2) to the extreme right position.
Do not change direction of spindle when the spindle is rotating.
5.9. 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 done gradually, as periodically removed from the drill hole to remove chips or dust. If during drilling
to drill block up in holes, you should exclude drill. Use a change of direction of rotation to remove
the drill from the hole. Drill must be kept in alignment with the hole. Ideally, the drill should be placed
perpendicular to the surface of the material being processed. If the condition for perpendicularity is
not respected at work can lead to trapped or breakage in drill hole and injury to the user. Continued
drilling at low speed the engine from overheating threatens. Must make periodic breaks during work or
to allow the drill to work on no-load maximum speed for about 3 minutes. Do not obscure the openings
in the hull used for ventilation of the engine.
5.10. Make periodic breaks at work.
5.11. Keep and refer to the accessories carefully.
5.12. Do not throw the tool, do not overload, do not soak in water and other liquids do not use it
for mixing adhesives and concrete coatings.
6. Operation and maintenance.
Clean the body with dry cloth. Do not use any cleaning agents, as they may damage the casing.
