- Power Regulator Adjustment:
- The tool features an adjustable power regulator, typically a dial or lever, located on the side or rear of the tool.
- Adjust this regulator to select the desired power output for tightening or loosening fasteners. Lower settings are for delicate tasks, higher settings for stubborn bolts.
- Forward/Reverse Mechanism:
- A directional switch (often a push-button or lever) allows you to select between forward (tightening) and reverse (loosening) rotation.
- Ensure the switch is fully engaged in the desired direction before operating.
- Operation:
- With the appropriate socket attached and air supply connected, place the socket onto the fastener.
- Squeeze the trigger to activate the tool. The impact mechanism will engage to apply torque.
- For tightening, release the trigger once the fastener is snug. For critical applications, always finish tightening with a torque wrench to the manufacturer's specifications.
- For loosening, maintain pressure on the trigger until the fastener is free.
