・Operating the pump at high-pressure region must be generated oil mist
from exhaust port. Attach the oil mist trap or connect the duct to
exhaust oil mist
If the pump rotation is not so smooth, take action needed as described
below.
・ Check oil quantity, and charge proper quantitative oil.
・ When stopping the pump for long term (3days or more) at low temperature,
pump oil will come into the pump cylinder. (At end of former operation,
vented air into the pump may also cause same situation) If restarting
the pump at this condition, over load protector may be operated. Then,
carry out several start-stop operations in a short time cycle.
After operating the pump for several hours, oil temperature inside the
pump may be risen up to 70 ～80℃. If the temperature is over this, the
pump may have troubles. Maintain the pump, or contact ULVAC KIKO,Inc.
