：
1) Value of the input source current has to be the same as the one on the plague.
2) The wiring has to follow the instructions on the plaque to avoid damaging the oil pump.
3) Ground the ground wire.
4) A filter is installed on the inlet of the oil tank. Do not contaminate the manifold block
components.
5) Wash the filter whenever it is contaminated to maintain its function.
6) Do not drop oil, water or other onto the control circuit, or the control circuit may be

4-2 Spindle Bearing Lubrication
High quality lube oil is used for the spindle bearing, and it is good for high temperature and high
speed conditions. Its lubricating effect on the bearing is long-lasting without being too oily, and
therefore there is no need to add or to change the lube oil for a while. It is therefore cost-saving.
4-3 Guide way and Ball Screw Lubrication
The linear guide way of X, Y and Z axes and the ball screws are lubricated by a centralized
lubrication system which lubricates according to the set schedule. Machine operators must ensure
that the oiling machine has enough oil, as well as whether there is any abnormality.
1) Lead Screw Lubrication
The bearing of the lead screw can be divided into the motor end and the housing end. Lube oil is
applied onto both ends for oil sealing. If the oil goes bad, dissemble these parts to wash the
bearing and reassembling them. Please contact the Company to have professionals checkup and
modification for you.
2) Guide way Lubrication
Guide ways of the workbench (X-axis), the saddle (Y-axis), the head (Z-axis), ball screws of the three
axes (X, Y and Z axes) and the nuts are lubricated by the automatic centralized lubrication system
in which an oil pump is located at the back of the machine.
