Troubleshooting Common Issues
Issue #1: No “Click” Sound at Preset Torque
Problem: You apply force to the wrench but don’t hear or feel the distinct “click” that signals the target torque has been reached.
Solution: First, verify you’re within the 10-150 ft/lb range. Ensure you’re applying force smoothly and continuously—jerky motions can affect the mechanism. Check that the locking collar is fully engaged at your desired setting on the high-contrast scale.
Prevention: Always store the wrench in its included case at the lowest setting (10 ft/lb) to maintain the ±4% calibration.
Issue #2: Inconsistent or “Mushy” Click
Problem: The click feels weak, inconsistent, or happens at different points when torquing identical fasteners.
Solution: This often indicates the internal mechanism needs lubrication or has been damaged by impact. Avoid using the wrench as a breaker bar or hammer. Ensure you’re using the correct 1/2″ drive sockets—using adapters can affect torque accuracy.
Tech Note: The dynamometric (click-type) mechanism relies on a calibrated spring; impacts can permanently affect its ±4% accuracy.
Issue #3: Difficulty Reading the Scale
Problem: The torque scale is hard to read, especially in low-light garage conditions.
Solution: The EPAuto features a high-contrast dual range scale specifically for this issue. Clean the scale with a dry cloth—dirt or grease can obscure the markings. Use a work light if necessary to illuminate the laser-etched numbers for precise setting.
Prevention: Wipe down the knurled handle and scale after use to prevent oil buildup.
Issue #4: Rust or Corrosion on the Shaft
Problem: You notice rust spots developing on the satin-finished steel.
Solution: While the satin finish is corrosion-retardant, it’s not rust-proof. Light surface rust can be removed with fine steel wool (0000 grade) and a protective oil like WD-40. Dry the wrench thoroughly after use in humid conditions.
Safety Feature: Always store the tool in its included sturdy plastic case to protect the Chrome Vanadium steel from moisture.
Issue #5: Extension Bar Doesn’t Fit or Feels Loose
Problem: The included 5-inch extension bar doesn’t seat properly in the 1/2″ drive head.
Solution: Clean both the square drive and the extension bar’s female end of any debris or manufacturing residue. The fit should be snug but not forced. Remember that using extensions can slightly increase the applied torque due to leverage—this is physics, not a tool defect.
