2. Istruzioni di sicurezza
Osservare sempre le precauzioni di sicurezza di base per ridurre il rischio di incendi, scosse elettriche e lesioni personali durante l'utilizzo di utensili elettrici.
2.1 Avvertenze generali sulla sicurezza degli utensili elettrici
- Sicurezza dell'area di lavoro: Mantenere l'area di lavoro pulita, ben illuminata e libera da ingombri. Non utilizzare utensili elettrici in atmosfere esplosive, ad esempio in presenza di liquidi, gas o polveri infiammabili.
- Sicurezza elettrica: Power tool plugs must match the outlet. Never modify the plug. Avoid body contact with earthed or grounded surfaces (e.g., pipes, radiators, ranges, refrigerators) to reduce the risk of electric shock.
- Sicurezza personale: Always wear appropriate personal protective equipment, including eye protection, hearing protection, and a dust mask. Dress properly; avoid loose clothing or jewelry. Do not overreach and maintain proper footing and balance at all times. Stay alert and use common sense when operating a power tool.
- Uso e cura dell'utensile elettrico: Do not force the power tool; use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Store idle power tools out of the reach of children.
- Servizio: Have your power tool serviced by a qualified repair person using only identical replacement parts to ensure the safety of the power tool.
2.2 Specific Safety Rules for Rotary Hammers
- Indossare protezioni auricolari. L'esposizione al rumore può causare la perdita dell'udito.
- Utilizzare le maniglie ausiliarie fornite con l'utensile. La perdita di controllo può causare lesioni personali.
- Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.
- Assicurarsi sempre che il pezzo in lavorazione sia ben chiusoampo tenuti fermi per impedire il movimento durante il funzionamento.

4.1 Fissaggio della maniglia ausiliaria
The auxiliary handle provides improved control and safety during operation. To attach, loosen the handle clamp, slide the handle onto the tool's barrel, and then tighten the clamp securely in a position that is comfortable and provides optimal leverage for your task.
4.2 Installing and Removing SDS-Plus Drill Bits and Chisels
- Clean the shank of the SDS-Plus drill bit or chisel and apply a thin layer of grease to reduce friction and wear.
- Insert the bit into the SDS-Plus chuck until it clicks and locks into place. Pull on the bit to ensure it is securely seated and cannot be easily removed.
- To remove the bit, pull back the chuck sleeve firmly and then pull out the drill bit or chisel.

4.3 Impostazione del misuratore di profondità
Insert the depth gauge into the designated hole on the auxiliary handle. Adjust the gauge to the desired drilling depth by sliding it in or out, then secure the auxiliary handle to fix the depth gauge in position. This helps achieve consistent drilling depths.
5. Istruzioni per l'uso
5.1 Selezione della modalità
The CT18114 offers three distinct operating modes, selected via the mode selector switch:
- Modalità di perforazione (solo rotazione): Ideal for drilling in materials such as wood, metal, and plastic where no hammering action is required.
- Modalità di perforazione a percussione (rotazione con percussione): This mode combines rotation and hammering, making it suitable for drilling in hard materials like concrete, brick, and masonry.
- Modalità scalpellatura (solo martellatura): Designed for light chiseling, chipping, and demolition work, such as removing tiles or breaking small sections of concrete.
Rotate the mode selector switch to the desired setting. Ensure the switch clicks firmly into place to prevent accidental mode changes during operation.
5.2 Avvio e arresto
- To start the tool, press the trigger switch. The speed can be varied by the amount of pressure applied to the trigger.
- Per un funzionamento continuo, premere il pulsante di blocco mentre si tiene premuto il grilletto.
- To stop the tool, release the trigger switch. If the tool is locked on, press the trigger again to release the lock-on button.
5.3 Working Tips
- Apply moderate, steady pressure; do not force the tool. Excessive pressure will not speed up the drilling process and can damage the tool or bit.
- For hammer drilling, allow the tool's hammering action to do the work. Guide the tool rather than pushing it aggressively.
- Regularly check the drill bit or chisel for wear and replace it if it becomes dull or damaged to maintain optimal performance and safety.
6. Manutenzione
Proper maintenance ensures the longevity and optimal performance of your Crown CT18114 SDS-Plus Hammer.
6.1 Pulizia
Keep the ventilation openings on the tool clean and free from dust and debris to prevent overheating. Regularly clean the SDS-Plus chuck and the tool body with a soft, damp cloth. Do not use solvents, as they can damage plastic parts.
6.2 Lubrificazione
The SDS-Plus chuck mechanism benefits from occasional lubrication. Apply a small amount of specialized grease to the shank of the drill bit or chisel before insertion. This ensures smooth operation, reduces wear, and prolongs the life of the chuck.
6.3 Sostituzione delle spazzole di carbone
When the carbon brushes are worn, the motor may exhibit excessive sparking, reduced power, or stop working entirely. Carbon brushes are wear parts and should be inspected periodically. Replacement of carbon brushes should only be performed by a qualified service technician to ensure proper function and safety of the tool.
