WARNING
The motor and speed reduction gear casing are extremely hot after auto- matic operation, so burns may occur if these are touched. Before han- dling these parts during inspection or servicing, turn OFF the controller, wait for a while and check that the part has cooled.
WARNING
Precautions for handling harmonic grease and washing oil
•Inflammation may occur if the grease gets into eyes.
Always wear protective goggles, etc., to protect eyes when handling the grease.
•Inflammation may occur if the grease gets on skin. Wear protective gloves, etc., to protect skin when handling the grease.
•Do not consume the grease. (Consumption of grease will cause diarrhea and vomiting.)
•Wear protective gloves when opening the can to prevent injury to hands.
•Store the grease out of the reach of children.
•Do not heat the grease or place it near fire. There is a risk of igniting or fires.
Remedial measures
•If the grease gets into eyes, flush eyes for 15 minutes with clean water, and then see doctor.
•If the grease gets on skin, wash off completely with water and soap.
•If the grease is consumed, do not induce vomiting, and instead con- sult with a doctor immediately.
WARNING
Disposal of harmonic grease, spent washing oil and waste containers
•Disposal methods are specified by law. Always follow local laws when disposing of these items.
•Do not apply pressure on an empty container. The container could rup- ture if pressurized.
•Do not weld, heat, open a hole or cut this container. Failure to observe this could lead to an explosion and igniting of the residual matter.
!CAUTION
Use of grease not recommended by YAMAHA could lead to a drop in the har- monic drive life.
