2-5 Installation
・
Please watch for overloading situation.
・
Please make sure the rotation speed is within the specification.
・
Please make sure the surface of the reducer is below 60
℃
.
・
Stop the operation immediately and inspect the device if following conditions are observed.
• Abnormal temperature rise
• Abnormal noise or vibration
• Unstable rotational speed
• Please check for the following list of possible root causes for the abnormalities.
• Overloading.
