2.1.1 Precautions for Maintenance
• Perform disassembly and assembly according to the procedures described in the manual.
• The parts for the Reduction Gear Unit are managed with serial numbers. Before installing parts, make sure the serial numbers of each match.
Combining parts with different serial numbers may result in vibrations, abnormal noise, or other issues that may affect the accuracy of the
robot.
• Remove connectors by releasing the latch. When connecting connector, make sure the latch is closed.
• Do not pull the connector or cable with force. Doing so may cause damage.
• When fixing the covers and plates, be careful not to pinch the cables.
• When cutting a wire tie, be careful not to damage the cables.
• Installation of a Silicone Sheet or securing with a wire tie are measures to prevent pulling or grazing of the cable when the robot moves, and
also to prevent friction between connectors. Use the Silicone Sheet and wire tie according to the instructions in the manual to fix the cables.
• Make sure that the wire tie is not over-tightened with force.
• When tightening screws, use the correct tightening torque. For details, refer to 1.2.6 Tightening Bolts/Screws.
• Fasten the bolts aligned on a circumference in a crisscross pattern. For details, refer to 1.2.6 Tightening Bolts/Screws.
• When loosening Motor Plate securing screws, or attaching or removing parts that affect belt tension, make sure to adjust the timing belt
tension.
For details, refer to 3.1 Adjusting the Timing Belt Tension.
• Before applying grease, wipe off the old grease and anti-rust oil. If any old grease is left behind, the lubrication may deteriorate, the anti-rust oil
may harden, and the robot accuracy may be affected.
• Apply the specified amount of grease to the parts specified in the manual.
• When applying grease, take care that the grease does not adhere on to the surrounding parts. Oil separation of the surrounding grease may
result in oil leakage. Therefore, be sure to wipe off any adhering grease.
