10. User Tips

• This impact wrench is very torquey and effective for pulling bolts off trucks (e.g., F-250, F-150) and smaller farm equipment.
• For extremely heavy-duty farm equipment or excavators, consider models with 1000 ft-lbs (1600 N.m) or higher torque.
• The included 14mm socket is a useful addition not always found in similar kits.
• For maximum torque output, especially when dealing with very stubborn fasteners, ensure you are using fully charged batteries, preferably 4.0Ah or higher.
