MAINTENANCE OF VACUUM PUMP
Proper maintenance of the vacuum pump is essential to ensure its optimal
performance. Here are some maintenance guidelines:
Keep the pump clean and free from foreign matter.
Keep the oil filled to the oil level, and never let the pump run without
oil.
Keep the oil clean. If the oil becomes dirty, muddy, or water or other
volatile substances get in, it will affect the performance of the pump,
and the oil should be replaced. To replace the oil, start the pump and
run it for about 30 minutes to make the oil thin. Then stop the pump
and drain the oil from the oil drain plug. Open the gas inlet and run the
pump for 1-2 minutes while adding a small quantity of clean oil to the
gas inlet. This is to replace the residual oil from the inside of the pump.
After ensuring that the pump is clean, put the drain plug back in and fill
the clean pump oil from the gas inlet to the oil level.
To store the pump when not in use for long periods of time, cover the
oil cap and exhaust cap (if applicable) and store it in a dry place.
Repair of the pump should only be done by a qualified service
technician.
