Do not enter the area under the reduction gear when lifting the reduction gear. If the reduction gear
falls down, it could cause injury.
When lifting the
reduction gear
, be sure to use a lifter that can withstand the weight of the reduction
gear. Otherwise, the lifter will be damaged, and the reduction gear could fall down and topple over,
which may result in injury.
Be sure that no load is applied to the hollow section when lifting. The reduction gear could be
damaged and the components could fall down, which may cause injury to the workers. In addition, the
oil seals for the hollow section may be deformed, which could eventually cause leakage of the
lubricant.
