Overload Protection
The power cutter is fitted with an overload/overheat protection device. When the tool is
forced to work at an excessive load, the protection device will be activated automatically
to disconnect the power supply. If this occurs, switch off the tool and switch on again to
resume the work, make sure to apply only suitable workload to the tool. When the tool
works under heavy load for a long period of time, the temperature of the tool or battery
pack will increase significantly. The protection device will be activated at a preset temperature
to protect both the tool and the battery. If this occurs, switch off the tool and wait until it
cools down to ambient temperature and resume work.
Note: when the voltage of battery pack is dropped to 7.5V, the protection device will also be
activated. In this case, remove the battery pack and fully charge it before reuse.
