Abstract: A hand held power tool, for example a chain saw is provided with a transversely extending front handle and with a second handle which extends over the top of the power unit of the tool in a fore-and-aft direction. The fore-and-aft handle is provided with a forward hand grip portion located approximately above the center of gravity of the power tool and a rearward hand grip portion located at the rear of the power unit. An independently operable trigger member controlling the engine throttle is provided for each hand grip portion so that the engine can be controlled by an operator gripping either hand grip portion of the fore-and-aft handle. Moreover, a choke valve operating member is provided adjacent the forward hand grip portion while an onoff switch is located below a median portion of the fore-and-aft handle in position to be operated by an operator holding the tool by either hand grip portion.
