- While supporting the bottom of the chassis using a jack, be sure to support the chassis using the blocks.
- When the boom or bucket is raised or when a unit is lifted by a crane, be sure to place a stand or adequate cribbing under the unit to prevent unexpected dropping.
- Do not start to work in an enclosed area if adequate ventilation is not provided.
- To remove a heavy unit (20kgf (40 lbs) or more), be sure to use a crane or other lifting tool.
