What safety precautions should I follow before performing maintenance on the RER 1000?

Before starting any maintenance, ensure the engine is shut off and cool, and disengage all controls. Allow the engine to cool for at least 30 minutes before cleaning or servicing, and be careful not to touch the muffler, as it can cause severe burns or death. Never attempt adjustments while the engine is running, except disengaging the PTO lever and moving the shift lever into neutral. (Page 2)
