10.1
Notes when Disassembling and Reassembling the
Balancer Unit
Carefully read and observe the precautions below when disassembling
and reassembling the balancer unit.
Fig. 10-1: Notes when Disassembling and Reassembling the Balancer
Unit
NOTICE
•
Do not damage the rod part of the balancer unit.
•
Do not apply any horizontal forces to the rod part.
•
When lifting the balancer unit, do not attach lifting jigs to the rod part
and/or clevis.
•
Do not use the balancer unit with foreign substances at the rod part
or the entry of the rod to the cylinder.
Failure to observe this may damage the sealing inside the balancer
unit, and this may cause the grease leakage or abnormal noise.
DANGER
•
Be sure to mount the spring fixing bolts when removing the balancer
unit from the manipulator. If the balancer is removed without the
spring fixing bolts, the rod will rapidly shrink which may result in
injury or accident.
•
Before removing the balancer unit from the manipulator, confirm
that the L-axis motor brake is appropriately functioning and L-axis is
firmly secured with a chain block, etc., to prevent it from rotating.
Failure to observe this instruction may rotate the L-axis and cause a
hazardous condition.
•
Before unscrewing the spring fixing bolts, confirm that the L-axis
motor brake is appropriately functioning.
Failure to observe this instruction may rotate the L-axis and cause a
hazardous condition.
NOTE
Although the balancer unit position would not deviate when
disassembled and reassembled, refer to
before replacement just in case.
