4-6 Cylinder Lubrication
1. Normally, oil in the oil cup will be depleted eventually. The oil will be used up after about 500,000
times.
2. Normally, it is recommended to remove the remaining oil from the oil cup each year and add new
one when doing the machine maintenance (dot not disassemble the oil cup, or it may be
damaged).
3. The color of the oil will be darkened if it has not been replaced for a long time. It will affect the air
pressure and lifespan of the machine. Check it routinely or monthly.
4. It is abnormal is the oil is depleted within 2 to 3 days. Check whether there is leakage at the oil cup
or the cup is broken. If so, replace the oil cup. If the depletion is abnormal, the boosting cylinder
may need to be replaced immediately to protect the spindle.
