Figure 4: Compatible (green check) and Incompatible (red cross) battery types. - Installazione della presa: Select the appropriate 1/2" square drive impact socket for your application. Push the socket firmly onto the square drive anvil until it locks into place. To remove, pull the socket off while pressing the release button (if present on your socket type).
4. Istruzioni per l'uso
Follow these steps for safe and effective operation of your impact wrench.
- Accensione/spegnimento: The tool is activated by pressing the trigger switch. Release the trigger to turn off the tool.
- Direction of Rotation (Forward/Reverse): Use the forward/reverse selector switch, typically located above the trigger, to choose the desired direction. Push the switch to the left for forward (tightening) and to the right for reverse (loosening).
-
Torque/Speed Adjustment: The WU279 features an adjustment button to switch between high and low torque/speed settings. This allows you to match the power output to the task at hand.

5. Manutenzione
Regular maintenance ensures the longevity and optimal performance of your WORX WU279 Impact Wrench.
- Pulizia: Mantenere le aperture di ventilazione dell'utensile pulite e libere da detriti per evitare il surriscaldamento. Utilizzare un panno morbido eamp panno per pulire l'esterno. Non utilizzare prodotti chimici aggressivi o detergenti abrasivi.
- Motore Brushless: The brushless motor design reduces wear and tear, requiring less maintenance compared to brushed motors. No carbon brush replacement is needed.
- Magazzinaggio: Store the tool in a dry, secure place, out of reach of children. If storing for extended periods, remove the battery pack.
- Cura della batteria: Even though batteries are not included, if you own WORX 20V batteries, ensure they are stored in a cool, dry place and charged periodically if not in use for long durations to maintain their health.
6. Risoluzione Dei Problemi
Se riscontri problemi con la tua chiave a impulsi, fai riferimento ai seguenti problemi comuni e alle relative soluzioni:
-
Lo strumento non si avvia:
- Ensure the battery pack is fully charged and correctly inserted.
- Controllare che il selettore avanti/indietro sia in posizione neutra (bloccato).
-
Potenza o prestazioni ridotte:
- La carica della batteria potrebbe essere bassa. Ricaricare la batteria.
- Ensure you are using a compatible WORX 20V KROSS PACK battery. Incompatible batteries may lead to suboptimal performance or damage.
- The selected torque setting might be too low for the task. Adjust to a higher torque setting if needed.
-
Surriscaldamento:
- Lasciar raffreddare lo strumento.
- Assicurarsi che le fessure di ventilazione siano libere da ostruzioni.
- Evitare un uso continuo e gravoso senza pause.
7. Suggerimenti per l'utente
- Selezione della presa: Always use impact-rated sockets with your impact wrench. Standard sockets are not designed to withstand the high impact forces and may shatter.
- Compatibilità della batteria: Double-check that any battery and charger you intend to use are explicitly compatible with the WORX 20V KROSS PACK system to avoid damage to the tool or battery.
- La sicurezza prima di tutto: Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when operating the impact wrench.
- Coppia ottimale: Start with a lower torque setting for sensitive applications and increase as needed to prevent overtightening or damaging fasteners.
