Simple Fix for Makita Cordless Grinder: How a Loose Nut Halts Cutting Power

Dublin, Ireland – Dean Doherty, a local content creator known for his tool teardowns and repair videos, recently shared a practical solution for a common issue affecting Makita cordless grinders. In his latest video, Doherty addresses the problem of a grinder that appears to function normally but fails to cut under load. The issue, as demonstrated by Doherty, stems from a loose nut on the armature shaft within the grinder's mechanism. This allows the gear to slip, preventing the cutting disc from engaging effectively. Doherty meticulously guides viewers through the repair process, which involves disassembling the grinder, securing the loose nut with a spanner and a vice, and then reassembling the tool. Following the repair, Doherty showcases the grinder operating at full capacity, successfully cutting material without any slippage. The straightforward fix highlights that not all tool malfunctions require professional repair or replacement, offering a valuable insight for tool owners and DIY enthusiasts.
