These are general diagnostic paths for this product category. Error-code numbers differ between brands, markets and revisions, so EgoFile shows a code only after it is confirmed in the exact official manual.

Source policySafe checks are maintained by EgoFile and linked to the official source record. No third-party manual text is copied.
01POWER

Tool does not start

Medium priority

What it means: The supply, battery, lock-off or electronic protection may be preventing operation.

First safe check: Remove the accessory load, verify the power source and follow the documented reset.

Stop condition: Stop for damaged insulation, a swollen battery or repeated breaker trips.

02STALL

Accessory stalls or binds

High priority

What it means: The accessory, feed rate, material or selected mode may be unsuitable.

First safe check: Disconnect power, free the accessory and confirm its rating and installation.

Stop condition: Do not restart until the cause of binding and kickback has been removed.

03VIBRATION

Abnormal vibration or run-out

High priority

What it means: An accessory may be damaged, loose, unbalanced or incorrectly mounted.

First safe check: Stop immediately and inspect the accessory, flange, chuck and guard.

Stop condition: Replace damaged parts; never test a cracked abrasive wheel.

What it means: Blocked cooling, excessive load or duty-cycle limits may have activated protection.

First safe check: Switch off, clear external vents and let the tool cool naturally.

Stop condition: Request service for smoke, melting, smell or repeated shutdown.
