OVERLOAD PROTECTIVE DEVICE FOR POLY-V-BELT

The power of the motor is transmitted to the saw blade by a Poly-V-Belt. When the Poly-V-Belt becomes overloaded, the overload protective device cuts off the current to stop the motor.

In this case turn the switch off immediately and raise the handle to its initial position. Then turn the switch on and after running the tool for 20 seconds without a load for cooling of the motor. Then start the cutting operation. The Poly-V-Belt or the motor will be damaged if the overload protective device turns off frequently.

CAUTION: When the overload protective device stops the motor, the motor will start by turning the switch on after turning it off. When turning the switch on, make sure that the saw blade is not halfway in the material.
