VACUUM SYSTEM TESTING
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of
this document including all text under subheadings therein before set up or use of
this product.
1. Open the Cup (3).
2. Seat the O-ring (11) completely into the groove in the top of the Cup (3).
3. Remove the shipping spacer that prevents the Vacuum Pump (1) handle from moving through
its full range.
4. Cover the inlet of the Vacuum Pump with something such as the plastic bag. To prevent injury,
DO NOT USE YOUR SKIN TO PLUG THE INLET. Operate the pump several times to create
the vacuum. The vacuum should not decrease quickly. If air is entering through the vacuum
release valve, tighten it. After the pump properly holds a vacuum, press in the Pump’s vacuum
release valve to release the vacuum.
Set the plastic bag aside.
5. The vacuum pump should now be ready for use.
1. Position the vehicle in a flat, level outdoor area. Set the parking brake and chock the tires.
2. Attach a 23" Hose (4) to the Vacuum Pump (1).
3. Attach the other end of the Hose to the vacuum system. Keep clear of parts that will move
or get hot while an assistant starts the engine. Wait until the vacuum reading stabilizes and
compare it to the manufacturer’s specification.
4. After obtaining a measurement, shut off the engine.
5. A low or unstable vacuum reading may mean a vacuum leak, vacuum line blockage, cylinder
sealing problems, incorrect valve/ignition timing, or other issues.
Note: Vehicle vacuum systems will differ. Consult the vehicle’s service manual for proper
testing procedures.
6. After testing is complete, disconnect the Vacuum Pump and Hose, remove any plugs or
clamps and secure all vacuum lines.
