    1.3) Safety General note Although the reading of such information does not eliminate the hazard, understanding the information will promote its correct use. Always use common workshop safety practice. The information and components-/system descriptions contained in this Manual are correct at the time of publication. BRP-Powertrain, however, maintains a policy of continuous im- provement of its products without imposing upon itself any obliga- tion to install them on its products previously manufactured.
  • Page 14: Safety Notice

    WARNING or death! Unless correctly equipped to provide enough electrical power for night VFR (according la- test requirement as ASTM), the ROTAX 912 UL/ULS/ULSFR is restricted to DAY VFR only. Certain areas, altitudes and conditions present greater risk than others. The engine may require humidity or dust/sand preventative equipment, or additional maintenance may be re- quired.
  • Page 15 Instrumentation Select and use proper aircraft instrumentation. This instru- mentation is not included with the ROTAX engine package. Only approved instrumentation may be installed. Engine log book Keep an engine log book and respect engine and aircraft maintenance schedules.
  • Page 16 Engine run Never operate the engine without sufficient quantities of oper- ating fluids (oil, coolant, fuel). Never exceed the maximum permitted operational limits. In the interest of safety, the aircraft must not be left unattended while the engine is running. To eliminate possible injury or damage, ensure any loose equipment or tools are properly secured before starting the en- gine.

  • Page 72 Backlash On the gearbox version with overload clutch the design incorpo- rates a friction damped free play at the dogs to warrant proper en- gine idling. Due to this backlash at the dogs a distinct torsional impact arises at start, stop and at sudden load changes, but due to the built-in overload clutch it will remain harmless.
