5-2

Performing periodic inspection and maintenance of the I/P Converter will help reduce the

incidence of faults and extend the working life of the unit.

・A metal mesh is fitted inside the SUPPLY coupling. Use a pair of tweezers or similar to

remove any sealing tape or dirt particles caught in the mesh.

・The fixed orifice plays an important role in supplying the air to the nozzle. If no nozzle back

pressure is present, this may indicate a blocked orifice.

・Take off the exhaust cover, then remove the fixed orifice assembly from the pilot relay unit

and replace with a spare assembly. (See Figure 5-1)

・If you do not have a spare fixed orifice assembly, use [phi]0.3 piano wire or similar to clean

the blocked orifice. Then use clean air to blow off any remaining dirt.

・When finished cleaning, screw the assembly back into its original position. Take care to

ensure that the O-ring is positioned correctly in the body of the pilot relay unit.
