Safety signs (decals)
For the safety of the operator and the personnel working around the site, safety signs (decals)
are placed at certain locations on the machine as shown below. Walk around the machine with
this manual, and check the content and location of these safety signs. Review these signs and
the operating instructions in this manual with your machine operators.
• Keep the signs clean and legible. If any of the safety labels is peeling or damaged and
becomes difficult to read, replenish it with a new one. Please include your product serial
number when ordering a new sign from the Takeuchi service agent.
• When a part/unit to which a safety sign is attached is replenished, a new sign must be
attached to the new part/unit.
