Stop vaping immediately and do not attempt to override or restart the device while the warning is showing. The shut-down is a safety protection and must be allowed to complete its job.
Move the device away from any heat source, direct sunlight or warm surface. Place it somewhere cool and well-ventilated.
Do not disassemble the device or remove any internal components while it is cooling. The manual states the device should not be disassembled without Lost Vape's recommendation.
Wait for the internal board temperature to drop back to 60°C or below. Only once it has cooled sufficiently will the device allow you to vape again. This may take several minutes depending on how warm the surroundings are.
Once the device has recovered and the warning has cleared, resume vaping with shorter, more spaced-out puffs to avoid the board overheating again.
If the 'Too Hot' warning appears repeatedly under normal vaping conditions or in a cool environment, stop using the device and contact Lost Vape support or the retailer, as this may indicate a fault requiring professional assessment.
