WARNING : INJURY
Do not open the check door when the starter switch is in the AUTO or START position.
It will cause injury by rotating parts such as cooling fans and fan belt.
Always turn the starter switch to the STOP position and stop the engine, then close
and lock OPERATION PANEL DOOR before checking or maintaining the engine or
any equipment.
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after stopping the
engine as they are still extremely hot.
Hot steam gushes out from the coolant sub-tank if the generator overheats. Do not
touch the coolant sub-tank.
This generator is equipped with functions to automatically stop operation when there is a
fault/malfunction during operation, and one to warn the operator of the fault location by use of
indicator lamps. Check the fault location when the engine is automatically stopped or an
indicator lamp illuminates to stop the engine.
