Engine, Generator, And Controls Assembly; Basic Engine; Engine Manufacturer's Equipment - Hobart 90 C 20 Operation And Maintenance Manual

This generator set is equipped with a canopy having doors on both sides. Panel mounted instruments
may be observed through two Plexiglass windows in the left rear door which covers the control box
and engine control panel. The lower window is slanted outward at the bottom to provide access to en-
gine controls when the door is closed. A centrally-located lifting eye attached to a lifting yoke extends
through the canopy top to provide an attaching point for chains, cables, or hook used to lift and move
the generator set.
