Preflight preparation

Blades, housings, handles no cracks , breakage .
Cable cords and plugs intact , normal switching operation , protect access to zero connected correctly , solid and reliable.
The blade is securely installed , whether the bolts tightened, both inside and outside chuck if the blade firmly clamped. The horizontal axis of the blade is

flat and vertical electric circular saw .
Inspection activities guard rotation is flexible, there is no distortion, and the circular saw blade will phase friction connection is reliable , the

operation will not fall off.
Check the side of the handle is installed securely , will loose grip when operating .
Checking whether the workpiece to be cut firmly fixed.
