(12) Do not allow a large amount of cutting powder from entering the pump. Otherwise, it may clog the
pump strainer, damage the pump, or significantly deteriorate the performance. If you use the
pump in processes such as grinding, milling, or end milling in which a large amount of cutting
powder is discharged, select the pump carefully.
(13) Stop the pump.
Caution
Keep the cocks of the pressure gauges, compound pressure gauges, and
other parts closed all the time except when they are used for
measurement. Otherwise, they are more prone to fail.
Caution
Do not operate the pump beyond the rated current value as this may cause
the motor to burn out. Check the pump nameplate for the rated current of
the pump.
Warning
Do not put your fingers or other objects into the opening of the motor.
Otherwise, it may lead to an electrical shock or injury.
