A laser level includes a housing, a pendulum pivotably mounted to the housing, and a laser diode assembly disposed on the pendulum. A gimbal assembly is employed for pivotably mounting the pendulum to the housing. The gimbal assembly includes a frame connected to the housing, a first pair of bearings disposed on the frame, an axle extending through the first pair of bearings, a body disposed on the axle and pivotably supporting the pendulum, and a second pair of bearings disposed between the body and the pendulum. The first pair of bearings is disposed on one side of the second pair of bearings.

A generator incorporating a double sided fan operable to generate dual, spaced apart, simultaneous cooling airflows within the generator to more efficiently cool internal components located on opposite sides of the fan. The double sided fan generates a first cooling airflow into a permanent magnet generator (PMG) assembly and a second cooling airflow through an electronics assembly. The first cooling airflow cools a stator disposed within the PMG assembly, while the second cooling airflow cools a plurality of circuit boards disposed within the electronics assembly. The fan exhausts both cooling airflows radially outwardly.
