Indicates operation has
been halted due to motor
or battery overheating.
The overheating protection feature halts
driver operation to protect the motor and

• If the overheating protection feature acti-
vates, allow the driver to cool thoroughly
(at least 30 minutes). The driver is ready
for use when the overheat warning lamp
goes out.
• Avoid using the driver in a way that
causes the overheating protection fea-
ture to activate repeatedly.
