5. Configurazione e connessione
- Alimentazione d'aria: Ensure you have a clean, dry, regulated air supply capable of delivering sufficient CFM (Cubic Feet per Minute) at the recommended operating pressure for heavy-duty impact wrenches.
- Collegamento del tubo dell'aria: Connect a 3/8-inch high-flow air hose to the tool's air inlet. Ensure all connections are secure to prevent air leaks.
- Lubrificazione: Before first use, and regularly thereafter, add a few drops of pneumatic tool oil into the air inlet. This lubricates internal components.
- Attacco presa: Select the appropriate impact-rated socket for your application. Align the socket with the 3/4-inch square drive anvil and push it firmly until it locks into place with the snap ring and pin hole retainer.
- Regolazione della pressione: Set your air compressor regulator to the recommended operating pressure for the tool. Do not exceed the maximum pressure.
6. Istruzioni per l'uso
- Controllo della direzione: The forward and reverse valve is located near the trigger.
- Per selezionare Inoltrare (tightening), move the valve to one of the three forward positions. These positions typically offer varying power levels.
- Per selezionare Inversione (loosening), move the valve to the single reverse position.
- Regolazione della potenza: The three forward settings allow for adjustment of torque output. Start with a lower setting for initial tightening or when working with sensitive materials, and increase as needed. The reverse setting typically provides full power for loosening.
- Applicazione dello strumento:
- Ensure the socket is securely attached to the fastener.
- Tenere saldamente l'utensile con entrambe le mani, mantenendo una posizione equilibrata.
- Press the trigger to activate the impact mechanism. Apply steady pressure to the tool.
- Rilasciare il grilletto per interrompere l'operazione.
- Serraggio dei dispositivi di fissaggio: For critical applications requiring specific torque, use a calibrated torque wrench for final tightening after using the impact wrench for initial fastening.
- Allentamento dei dispositivi di fissaggio: The reverse setting provides maximum power for breaking loose stubborn fasteners.
7. Manutenzione
Una manutenzione regolare garantisce la longevità e le prestazioni ottimali della vostra chiave a percussione.
- Lubrificazione giornaliera: Add 5-10 drops of high-quality pneumatic tool oil into the air inlet before each use, or at least daily if used frequently. This is crucial for the twin hammer mechanism and motor.
- Air Inlet Screen: Periodically inspect and clean the air inlet screen to prevent debris from entering the motor, which can extend tool life.
- Pulizia: Keep the tool clean and free of dirt, grease, and debris. Use a clean cloth. Do not use harsh solvents that could damage rubber components.
- Ispezione dell'incudine: Regularly check the anvil and socket retainer for wear or damage. Replace if necessary to ensure secure socket attachment.
- Qualità dell'aria fornita: Ensure your air compressor system includes an air filter and water trap to provide clean, dry air to the tool.
- Magazzinaggio: When not in use, store the impact wrench in a clean, dry place, away from excessive heat or moisture. Disconnect from the air supply.
- Rubber Handle Cover: Inspect the insulating rubber handle cover for wear or damage. A replacement cover (part number 905125) is available if needed.
8. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
