WARNING!
Wear safety glasses when cleaning the
fi

Clean the
fi
lter in a well-ventilated area.

1.
Open the latches (6), lift the hopper hood (16) and ensure that the support rod (17) is in place.
2.
Inspect the dust
fi
lter upper part (12) for damage. A large amount of dust on top of the
fi
lter is usually caused by a hole in the
3.
fi
lter or a damaged
fi
lter gasket.

fi
lter shaker assembly mounting knobs (13). Lift the
fi
lter shaker assembly (11) to access the

Clean the
fi
lter using one of the methods below:
6.
Method “A”
Vacuum loose dust from the
fi
lter. Then gently tap the
fi
lter against a
fl
at surface (with the dirty side down) to remove loose dust and
dirt.
NOTE
Take care not to damage the metal lip which extends past the gasket.
Method “B”
Vacuum loose dust from the
fi
lter. Then blow compressed air [maximum pressure 87 psi (6 Bar)] into the clean side of the
fi
lter (in
the opposite direction of the air
fl
ow).
Method “C”
Vacuum loose dust from the
fi
lter. Then soak the
fi
lter in warm water for 15 minutes, then rinse it under a gentle stream of water
[maximum pressure 36 psi (2.5 Bar)]. Let the
fi
lter dry completely before installing it back into the machine.
NOTE
For proper drying, lay the
fi
lter horizontally on two spacer to allow the air to
fl
ow under the
fi
lter.
NOTE
For a better cleaning, it is allowed to wash the
fi
lter with water and non-lathering detergents.
This provides better quality cleaning but reduces the life of the
fi
lter, which will have to be replaced more frequently.
Using inadequate detergents can damage the
fi
lter.
Install the
fi
lter in the reverse order of removal and note the following:
7.
Install the
fi
lter with the wire gauze up.
•
If the
fi
lter gasket is damaged or missing, it must be replaced.
•
NOTE
Before replacing
fi
lter clear debris from dust plate located under
fi
lter.
Check that the debris skirt at the rear of the dust plate swings freely.
