4.1. Aansluiten op de luchttoevoer
- Ensure your air compressor is capable of providing the required air pressure and volume (refer to specifications).
- Connect a suitable air hose (minimum 3/8" I.D.) to the air inlet of the drill. It is recommended to use an in-line air filter/lubricator unit to ensure clean, lubricated air supply.
- Secure all connections to prevent air leaks.
- Set the air compressor regulator to the recommended operating pressure.
4.2. Installing Drill Bits (Keyless Chuck)
- Ensure the air supply is disconnected from the drill.
- Draai de kraag van de klauw tegen de klok in om de klauw te openen.
- Steek de boor volledig in de boorkop en zorg ervoor dat deze gecentreerd is.
- Rotate the chuck collar clockwise to tighten the jaws firmly around the drill bit. Hand-tighten only; do not use tools to overtighten.
- Verify the bit is securely held before reconnecting the air supply.

- Zorg er altijd voor dat de boormachine volledig tot stilstand is gekomen voordat u de draairichting verandert.
5.3. Boortechnieken
- Always apply steady, even pressure. Do not force the drill, allow the tool to do the work.
- For drilling into metal, use a center punch to mark the drilling point to prevent the bit from wandering.
- Use appropriate drill bits for the material being drilled.
- Clear chips regularly, especially when drilling deep holes, to prevent overheating and binding.
- When drilling through thin materials, place a scrap piece of wood underneath to prevent splintering or tearing.
