摘要:
A metal cutting circular saw is provided with an upper blade guard which includes a first sight window disposed in a first side surface and disposed in a plane angularly offset from a plane of the blade. The upper blade guard also includes a second sight window disposed in the second side surface of the upper blade guard. A light window is disposed in a front portion of the perimeter outer surface of the upper blade guard. The upper blade guard is made from metal and the first and second sight windows and the light window are integrally formed as a one-piece member. The saw shoe and lower blade guard are configured to minimize chip spray from contacting a user.

A Very Local Area Network (VLAN) comprises a power strip device having an electrical connector for connection to an AC power supply line and one or more surge protectors and line filters. Multiple electrical power outlet sockets receive plugs from electrical appliances. A communications pathway interconnects the multiple electrical power outlet sockets to enable communication between appliances connected to the sockets. Electronics configure appliances as they are connected to the sockets to enable them to communicate over the communications pathway.

A battery powered circular saw includes a rechargeable battery removably attached to the housing and an adjustable shoe pivotally attached to a guard assembly for controlling a depth of cut. A locking mechanism for preventing relative movement between the adjustable shoe and the housing includes a depth of cut strap disposed adjacent a first sidewall of the housing. A lever is disposed adjacent a second sidewall of the housing. A tightening element interconnects the depth of cut strap and the lever. The battery powered circular saw additionally includes a handle extending from the housing. The handle is disposed substantially parallel to a direction of cut and oriented horizontally above the housing. The rechargeable battery pack includes a pair of laterally spaced apart guide rails which cooperate with the pair of longitudinally extending grooves to permit sliding movement of the rechargeable battery pack in a direction parallel to the direction of cut.
