2.1. Ugradnja i punjenje baterije
The impact wrench operates on 21V Lithium-ion batteries. Ensure batteries are fully charged before first use.
- Punjenje: Connect the charger to a power outlet and insert the battery. The indicator light on the charger will show the charging status. A full charge typically takes several hours.
- Instalacija: Align the battery with the base of the impact wrench and slide it in until it clicks securely into place.
- Uklanjanje: Press the battery release button (see Figure 1) and slide the battery out.

2.2. Pričvršćivanje utičnica
The impact wrench uses a 1/2-inch square chuck. To attach a socket:
- Select the appropriate impact socket for your task (e.g., 17mm, 19mm, 21mm, 22mm, 24mm).
- Push the socket firmly onto the square chuck until it locks into place.
- To remove, pull the socket off the chuck.
3. Operacija
3.1. Prekidač za naprijed i nazad
The forward/reverse switch controls the direction of rotation and also acts as a lock when centered.
- Forward (Tighten): Push the switch to the right for clockwise rotation.
- Reverse (Loosen): Push the switch to the left for counter-clockwise rotation.
- zaključavanje: Center the switch to prevent accidental activation. The tool will not operate when the switch is in the center position.

Slika 3: Detaljno view of the forward and reverse switch mechanism. Pushing right engages forward rotation (tighten), pushing left engages reverse rotation (loosen), and centering the button locks the tool.
3.2. Variable Speed Control and Torque Adjustment
The tool features stepless speed control and three torque settings to match various applications.
- Beskonačna kontrola brzine: The speed of the tool is controlled by the pressure applied to the trigger. Pressing the trigger harder increases the RPM.
- Postavke obrtnog momenta: Three torque options are available: 700 Nm, 950 Nm, and 1200 Nm. These settings can be selected via a control at the bottom of the wrench (refer to Figure 3 for visual indication of torque adjustment on the smart control panel).
- Niska (L): 0-1520 RPM, suitable for home improvement tasks.
- srednji (M): 0-1990 RPM, ideal for tire disassembly.
- Visoko (V): 0-2370 RPM, for engineering industrial use requiring maximum power.

3.3. LED svjetlo
Integrisano LED svjetlo se automatski pali kada se pritisne okidač, pružajući vidljivost u slabo osvijetljenim radnim područjima.

4. Održavanje
4.1. Generalno čišćenje
Redovno čišćenje pomaže u održavanju performansi alata i produžava njegov vijek trajanja.
- Nakon svake upotrebe, obrišite alat čistom krpomamp tkanina. Nemojte koristiti jake hemikalije ili abrazivna sredstva za čišćenje.
- Održavajte ventilacijske otvore čistim od prašine i ostataka kako biste spriječili pregrijavanje.
- Inspect the square chuck for wear and tear.
4.2. Briga o bateriji i skladištenje
Pravilna njega baterije osigurava optimalne performanse i dugotrajnost.
- Čuvajte baterije na hladnom i suvom mestu dalje od direktne sunčeve svetlosti i ekstremnih temperatura.
- Ne skladištite potpuno prazne baterije duži period. Povremeno ih punite ako ih ne koristite.
