DLE 120 - Engine Mounting; Mounting and Vibration Damping; Propeller Safety Guidelines

ENGINE MOUNTING
During the break-in process the engine must be installed in an environment where vibraon can be ab-
sorbed i.e. in the model or with so mount if bench running. Hard mounng to a bench without adequate
vibraon damping may cause vibraon damage to internal parts and shorten the life of the engine. The
best way for break-in process is mount the engine in the model.
Always stand clear of and behind the propeller; never allow anyone including yourself, to be in front of or
to the sides of the propeller when starng or running the engine. Anyone near the engine should wear
protecve eyewear. NEVER WEAR LOOSE CLOTHING near the engine or propeller.
