MAKE SURE THE IGNITION SWITCH IS SET TO OFF AND THAT ALL
POWER TO THE ENGINE IS DISCONNECTED. ENSURE ALL
OBJECTS/PERSONNEL ARE CLEAR OF THE PROPELLER'S
ROTATIONAL ARC. IF POWER IS ON, A LOOSE OR BROKEN WIRE
CAN CAUSE THE ENGINE TO START AND THE PROPELLER TO
TURN WHICH CAN LEAD TO A PROPELLER STRIKE, SERIOUS
INJURY, OR DEATH.
IF VOLCANIC ASH IS SUSPECTED ON THE ENGINE, DO NOT TOUCH
IT WITH BARE HANDS OR GET IT IN YOUR EYES. WEAR
PERSONAL PROTECTIVE EQUIPMENT. DO NOT USE WATER TO
RINSE IT OFF. VOLCANIC ASH CAN CONTAIN ACIDIC
COMPOUNDS WHICH MUST NOT BE INHALED OR TOUCHED SINCE
IT CAN CAUSE INJURY. REFER TO THE "VOLCANIC ASH
