such as mechanical protection.
.Check the product regularly to ensure proper operation.
Otherwise malfunction can cause an accident.
These instructions must be followed when performing
maintenance work:
.Turn off the power supply
.Stop the air supply, exhaust the residual pressure and
verify that the air is released before performing
maintenance work.

Safety Instructions (continued)
CAUTION
Perform a proper functional check after completing
maintenance work.
Stop operation when an abnormality is observed or the product is
not working properly.
Safety cannot be assured due to unexpected malfunctions.
NOTE
The direct-current power supply should be a UL authorized power
supply.
