FM-06: POWER CUTS OUT WHEN THE TOOL OR BATTERY IS MOVED

movement-dependent power cutout.

Diagnostic overview

movement-dependent power cutout.

Likely Root Causes

  • Dry contamination, wear, or damage at the battery contacts
  • Battery shell or latches allow electrical movement despite physical retention
  • Tool contact block or internal wiring is loose
  • Trigger, direction switch, brush, or motor connection is intermittent

Quick Checks

  1. Ordinary handling no longer interrupts power, or the internal intermittent path is conclusively routed to service.

Repair Preview

  1. Repeat with a known-good compatible battery to separate a pack-side intermittent condition from the tool-side path.
  2. With the chuck empty, make one brief no-load test while changing only normal hand orientation; do not flex, strike, shim, or hold the pack in place.
  3. If a proven battery still causes cutout with ordinary movement, remove it and route the contact block, wiring, switch, brush, or motor path to service.
  4. Release the trigger and remove the battery before inspecting the contacts, latches, stem, and tool rail path for heat, burning, looseness, or impact damage.
  5. Dry-clean the accessible contacts and latch surfaces, then install the original pack until the release latch pass an unpowered pull test.
