An electric power cutter comprising: - a rotatable saw structure - a rear handle with a speed control trigger - a front handle - a drive unit for rotating the saw structure, the drive unit itself comprising: - a saw structure drive arrangement to which the saw structure is attachable - a transmission for driving the saw drive arrangement - an electric motor for driving an input shaft of the transmission - a support structure for holding and carrying the saw structure drive arrangement, the transmission and the electric motor, wherein the front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit, characterised in that the power cutter includes a cooling fluid system comprising: - at least one cooling path (55;1055) in the motor, having an inlet for connecting to a fluid source and an outlet, said cooling path running within the side wall of the motor housing (52a, 52b;1052a, 52b) that is parallel to the rotor axis, and a fluid control unit arranged to control the fluid flow through the cooling path (55; 1055),where the fluid control unit connects to the outlet and includes at least one fluid valve which can direct fluid from the motor to a tool conduit leading to at least one nozzle at the rotatable saw structure and/or to a return conduit to discard or return the remaining flow to the fluid source, where the rear handle further includes a trigger lock opposite to the speed control trigger, the trigger lock having to be actuated in order to enable the speed control trigger to be actuated, said trigger lock further opening an inlet valve of the fluid control unit when being actuated, which inlet valve returns to a closed position when the trigger lock is not actuated. - a rotatable saw structure - a rear handle with a speed control trigger - a front handle - a drive unit for rotating the saw structure, the drive unit itself comprising: - a saw structure drive arrangement to which the saw structure is attachable - a transmission for driving the saw drive arrangement - an electric motor for driving an input shaft of the transmission - a support structure for holding and carrying the saw structure drive arrangement, the transmission and the electric motor, wherein the front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit, characterised in that the power cutter includes a cooling fluid system comprising: - at least one cooling path (55;1055) in the motor, having an inlet for connecting to a fluid source and an outlet, said cooling path running within the side wall of the motor housing (52a, 52b;1052a, 52b) that is parallel to the rotor axis, and a fluid control unit arranged to control the fluid flow through the cooling path (55; 1055),where the fluid control unit connects to the outlet and includes at least one fluid valve which can direct fluid from the motor to a tool conduit leading to at least one nozzle at the rotatable saw structure and/or to a return conduit to discard or return the remaining flow to the fluid source, where the rear handle further includes a trigger lock opposite to the speed control trigger, the trigger lock having to be actuated in order to enable the speed control trigger to be actuated, said trigger lock further opening an inlet valve of the fluid control unit when being actuated, which inlet valve returns to a closed position when the trigger lock is not actuated. - a saw structure drive arrangement to which the saw structure is attachable - a transmission for driving the saw drive arrangement - an electric motor for driving an input shaft of the transmission - a support structure for holding and carrying the saw structure drive arrangement, the transmission and the electric motor, - at least one cooling path (55;1055) in the motor, having an inlet for connecting to a fluid source and an outlet, said cooling path running within the side wall of the motor housing (52a, 52b;1052a, 52b) that is parallel to the rotor axis, and
