Warning
In the event of a power failure, be sure to turn off the power.
The pump may be suddenly started at the recovery from a power failure,
which leads to a danger.
(2) If you do not use the pump for a long time, observe the following points.
Caution
If you do not use the pump for a long time, turn off the power for safety.
Otherwise, accumulated dust may cause heating or ignition.
If the pump could be exposed to the freezing temperature in winter, be sure to apply antifreeze
measures such as heat insulation and heater installation to the pump or drain the pump.
If you have a backup pump, run it from time to time to make it available for operation at any
time.
5.2 Daily check
Check for any abnormal discharge pressure, current, vibration, noise, and other conditions at the
time of startup and during operation.
5.3 Periodic inspection
Caution
If you need to change any parts or overhaul or repair the pump, ask the
vendor, the service center specified by the manufacturer, or Teral Inc.
Improper work may lead to malfunctions or accidents.
(1) Clean the dirt and oil deposited on the outside surface of the coolant pump.
(2) Accumulated cutting powder in the tank (oil tank) may cause a pump failure. Clean the tank (oil
tank) at regular intervals.
(3) Check that the strainer of the pump is not clogged. If clogged, clean the strainer.
Caution
Clean the strainer on the pump suction side at regular intervals.
A clogged strainer may cause pressure fluctuations, decrease in delivery
volume, unusual noise, etc., which may lead to a pump failure.
