4. Tegniese spesifikasies

Note: The "Power Source: AC" specification appears to be a data entry anomaly for a pneumatic tool. This tool operates on compressed air.

5. Opstelling en verbinding

1. Lug toevoer: 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.
2. Lugslangverbinding: Connect a 3/8-inch high-flow air hose to the tool's air inlet. Ensure all connections are secure to prevent air leaks.
3. Smering: Before first use, and regularly thereafter, add a few drops of pneumatic tool oil into the air inlet. This lubricates internal components.
4. Sok Aanhegting: 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.
5. Drukregulering: Set your air compressor regulator to the recommended operating pressure for the tool. Do not exceed the maximum pressure.

6. Bedryfsinstruksies

1. Rigtingbeheer: The forward and reverse valve is located near the trigger.
   • Om te kies Vorentoe (tightening), move the valve to one of the three forward positions. These positions typically offer varying power levels.
   • Om te kies Omgekeerde (loosening), move the valve to the single reverse position.
2. Kragverstelling: 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.
3. Applying the Tool:
   • Ensure the socket is securely attached to the fastener.
   • Hold the tool firmly with both hands, maintaining a balanced stance.
   • Press the trigger to activate the impact mechanism. Apply steady pressure to the tool.
   • Laat die sneller los om die werking te stop.
4. Bevestigingsmiddels: For critical applications requiring specific torque, use a calibrated torque wrench for final tightening after using the impact wrench for initial fastening.
5. Loosening Fasteners: The reverse setting provides maximum power for breaking loose stubborn fasteners.

7. Onderhoud

Gereelde onderhoud verseker die lang lewensduur en optimale werkverrigting van jou impaksleutel.

• Daaglikse smering: 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.
• Skoonmaak: 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.
• Aambeeld Inspeksie: Regularly check the anvil and socket retainer for wear or damage. Replace if necessary to ensure secure socket attachment.
• Air Supply Quality: Ensure your air compressor system includes an air filter and water trap to provide clean, dry air to the tool.
• Berging: 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.
