3. Funtzionamendu-argibideak
3.1 Piztea/Itzaltzea eta Abiadura Aldakorreko Abiarazlea
The drill is activated by pressing the trigger switch. The speed is variable, meaning the further the trigger is pressed, the faster the drill operates.
- Pizteko, sakatu abiarazle etengailua.
- Itzaltzeko, askatu abiarazlearen etengailua.
- For slower speeds, press the trigger lightly. For faster speeds, press the trigger fully.
3.2 Aurrerako/Atzerako Kontrola
A forward/reverse button is located above the trigger to control the direction of rotation.
- Push the button to the left for forward rotation (clockwise).
- Push the button to the right for reverse rotation (counter-clockwise).
- Center the button for the lock-off position, which prevents accidental starting.
3.3 Speed Selector
The drill features a two-speed gearbox for optimal performance in different applications.
- 1. abiadura (abiadura baxua, 0-600 RPM): Use for high-torque applications such as driving large fasteners or drilling large diameter holes.
- 2. abiadura (abiadura handia, 0-2,000 RPM): Use for fast drilling with smaller bits or light fastening tasks.
To change speeds, slide the speed selector switch located on top of the drill. Ensure the drill is stopped before changing speeds to prevent gear damage.
3.4 Enbragearen ezarpenak
The adjustable clutch ring allows you to select the appropriate torque setting for driving screws, preventing over-driving or stripping. The numbers on the clutch ring correspond to different torque levels, with higher numbers indicating greater torque.
- Rotate the clutch ring to select a setting. Start with a lower setting and increase as needed.
- For drilling, set the clutch ring to the drill symbol (usually indicated by a drill bit icon) for maximum torque without clutch slippage.
