1. Stop-Down at Vacuum System
If – vacuum pump will not run.
Always check that there is power on the machine, and that it has not been disconnected by switch or by
fuse in the control box. Relay for pump may also be defective.
If – vacuum pump runs constantly.
Check that the slide valve is closed (should be closed to generate vacuum). Read pressure gauge (should be
about 0.60).
If – the pressure gauge indication is constantly about 0.7 or more.
In that case, there will be a fault on the vacuum guard.
If – the pressure gauge is constantly appr. 0.55 or less, and the pump is running.
In that case there would be a fault on the vacuum pump, or a leak on the hose connection between check
valve and vacuum pump.
If – the pressure gauge indication drops after the main switch has been disconnected, and the slide
valve closed.
In that case, there will be a fault – a leak between slide valve and check valve. Pressure gauge, slide valve or
vacuum guard may be defective. If hoses are dismantled at couplings, and the pressure continues to drop,
the fault will be with the slide valve.
