problems
21
Disconnect the machine from power before any check. Fixes marked Qualified person involve electrical, pressure or engine work: have them done by a qualified technician and follow the safety instructions in your IMER manual.
  1. Machine does not start
    Possible causeWhat to do
    Air The air pressure, with jet valve completely open, does not fall below the minimum pressure value on the machine pressure switch (table 1)Check that the air hose is not bent or obstructed Check that the jet nozzle is perfectly clean

    Qualified person: this fix involves electrical, pressure or engine work.
