Introduction:

• This manual describes the procedures of proper operation, inspection and maintenance of the machine and the items you have to observe for safety.
• Many accidents are caused by operation, inspection or maintenance of the machine that does not observe basic precautions. Being aware of the dangers to be expected in advance can also prevent accidents.

Safety Signs:
The safety signs used on this machine are described below.
• Be sufficiently aware of the precise locations of the safety signs, the danger indicated on the signs and how to avoid the danger.
• Keep the safety signs clean so that the contents are visible and legible. Do not use organic solvent or gasoline when cleaning the safety signs, as they may peel.
• If a safety sign gets damaged, becomes illegible or is lost, replace the sign with a new one. Check the part number of the safety sign in this manual or with the actual sign and order new signs from our sales service agency.
• There are labels other than the safety signs on this machine. Handle these labels in the same way as the safety signs.
