the drain port.
b. If the oil is contaminated, drain the oil by placing the pump on a level surface and opening the
oil drain valve. Catch the waste oil in a container and properly dispose of it.
c. If the pump has been sitting for more than one month, the oil is considered contaminated
regardless of appearance and should be changed as outlined above.
d. To add oil, close drain, remove the oil fill cap and fill to the Oil Level Line with fresh oil.
5. INTAKE CONNECTIONS
Replace all caps and finger-tighten. Do not use caps with damaged or missing O-rings and
always store vacuum pump with capped ports to prevent dirt and moisture contamination.
6. PUMP MOTOR
The PUMP and OIL must be above 30˚F (1˚C). The line voltage must be equal to the rating on the
motor nameplate ±10%. Normal operating temperature is approximately 160˚F (71˚C), which is
HOT to the touch! Line voltage and ambient temperature will affect the normal operating
temperature. Your vacuum pump is designed for continuous duty and will run for extended
periods without overheating. The motor has an automatic resetting overload protection feature. If
the motor will not restart the pump after shut-off, it may have opened the thermal protection.
Disconnect the pump from the system, wait about 15 minutes for the motor to cool down and
then try again.
WARNING:
1) Do not evacuate combustible, explosive or poisonous gases.
2) Do not evacuate gases that corrode metal or react chemically with pump oil.
3) The temperature of evacuated gas shall not exceed 176˚F (80˚C) and ambient temperature
shall be 41˚F ~ 140˚F (5˚C ~ 60˚C).
4) Do not operate without oil.
5) Do not touch the machine's hot surface during operation.
6) Do not block air outlet.
CAUTION:
To reduce the danger of electric shock, keep the pump indoors and do not expose to rain.
DANGER:
1) With a grounding socket the operating voltage is rated ±10%; Receptacle shall be well
grounded, or else electric shock may be caused. Should power cord or plug require
repair or replacement, do not connect grounded wire to any flat adapter connector. If its
surface is green, with or without yellow stripe, the insulation wire is grounding wire. If you
cannot fully understand grounding instructions and have doubt whether correct grounding is
made, check with a professional electrician or service man. Do not change the structure of
attached adapter connector.
2) When pulling out power plug, make sure to pull the plug rather than the wire.
3) Do not place heavy matter on power wire or let power wire be squeezed.
4) Do not use broken plug or socket.
5) Do not pull out power plug with wet hand.
6) Do not pull out, insert power plug or turn on power switch where flammable gases may be
present.
