JAVAC BULLDOG A2L Safety Instructions & Operation Manual page 9

7.3.1 Connect the electronic or mercury gauge to one of the pump's inlets. Make sure that all
connections are secured and vacuum tight.
7.3.2 Switch on the BULLDOG and allow it to warm up before taking a reading from the gauge.
Remember, contaminated or dirty oil will have an impact on the ultimate vacuum as will the type of
gauge used. With clean oil and a pump that is in 'new' condition, there would be a vacuum reading of
15-20 micron (on a digital gauge) and 5-10 micron (on a mercury gauge).
7.4 STORAGE
If storing for long periods:
• Run the pump until hot
• Drain the oil
• Add fresh oil
• Run for 5 minutes
• Switch off
• Seal inlet and exhaust
