Operating Instructions
Power Connection
Connect the drill to a standard 220V AC power outlet. Ensure the power switch is in the "OFF" position before plugging in the tool.
Selecting Operating Mode (Drill/Hammer Drill)
The drill features a mode selector switch, typically located on the top or side of the drill housing. Slide the switch to select between standard drilling (for wood, metal, plastic) and hammer drilling (for masonry, concrete, brick).
- Drill Mode: For drilling holes without impact.
- Hammer Drill Mode: For drilling into hard materials like concrete and brick, combining rotation with a hammering action.
Speed Control and Reversible Function
The drill is equipped with a speed variator and two mechanical speed settings (1,100 / 2,800 RPM) for optimal control across different materials and tasks. The electronic rotation control allows for precise speed adjustment via the trigger.
A reversible switch, usually located near the trigger, allows for changing the direction of rotation. This is useful for removing screws or freeing a jammed drill bit.
Drilling Procedure
- Mark the drilling spot accurately.
- Select the appropriate drill bit and operating mode.
- Hold the drill firmly with both hands, ensuring a stable stance.
- Place the tip of the drill bit on the marked spot.
- Start the drill at a low speed by gently pressing the trigger. Gradually increase speed as the bit penetrates the material.
- Apply steady, even pressure. Do not force the drill.
- Periodically withdraw the drill bit slightly to clear debris, especially when drilling deep holes.
- Once the desired depth is reached, release the trigger and wait for the drill bit to stop rotating before withdrawing the drill from the hole.
