• Contacts are dirty or the pack was not actually fully charged
• Internal motor or bearing drag is drawing excessive current

1. Under the same controlled cutting setup, the proven pack delivers repeatable useful runtime without abnormal heat or rapid loss of speed.

1. - Remove any pack that is hot, swollen, cracked, wet, leaking, or scorched - otherwise let it reach normal room temperature and charge it fully.
2. Clean the pack and saw interfaces dry, fit a sharp correct blade, and repeat a documented light-cut comparison in similar dry wood.
3. Repeat the same cut count and setup with a known-good fully charged compatible pack.
4. - Replace or service the pack that consistently delivers much less work - if both proven packs drain abnormally fast, keep the saw closed and request authoriz
