Suction Nozzle Rubbers
Removal
This can be effected without removing the nozzle assembly from the machine but if personnel are
inexperienced it will probably be easier to remove nozzle assembly and turn upside down. Release
two screws retaining bump bar at kerb end of nozzle. Release securing nuts retaining the rubbers. Pull
away the two short end rubbers, then remove the front and rear side rubbers.
Refitting
Reverse of removal procedure remembering to fit the radius rubber to the nozzle rear. Do not over
tighten the nuts as this will cause distortion of the rubber. Refit bump bar.
