IX. Maintenance and Service
If overload stop is stalled in this product, the whole product system will be
shut off by it. When overload stop is under work, first turn off the machine and
let in atmosphere from air inlet. Restart the machine after five minutes. (If ma-
nual reset overload stop is installed in this product, first press RESET but-
ton.) Should overload stop continuous work for many times, turn off the ma-
chine and shoot the trouble according to "8. Trouble shooting -- Difficult
starting". Restart the machine only after eliminating the trouble.
Keep pump clean and avoid foreign matter from falling in the pump.
Keep oil level and do not run the pump without oil.
Observe oil cleanness. If oil turns dirty and turbid or has some water or other
volatile matter so that ultimate vacuum is affected, replace pump oil in time.
When replacing oil, first run the pump for 30 minutes to thin down the oil, stop
the pump and discharge oil, then run 1-2 minutes with air inlet open and add a
little clean pump oil from air inlet to replace the residual oil in pump cavity. Re-
peat the steps for several times until the pump is clean. Replace oil dischar-
ging screw plug and refill clean pump oil to oil base line.
If the pump is not to use for a long time, mount the air outlet cap and place the
pump in dry place, keeping the pump dampproof and antirust.
If disassembly is needed for repair, only qualified and experienced persons
can do the repairing.
