DUST FILTER MAINTENANCE (PANEL FILTER)

The hopper dust filter must be cleaned regularly to maintain the efficiency of the vacuum system. Follow the recommended filter
service intervals for the longest filter life.
WARNING!
– Wear safety glasses when cleaning the filter.
– Do not puncture the filter.
– Clean the filter in a well-ventilated area.
– Wear appropriate dust mask to avoid breathing in dust.
1. Drive the machine on a level floor, engage the parking brake and turn the ignition key (66) to "0".
2. Open the latches (6), lift the hopper hood (16) and ensure that the support rod (17) is in place.
3. Inspect the dust filter upper part (12) for damage. A large amount of dust on top of the filter is usually caused by a hole in the
filter or a damaged filter gasket.
4. Unscrew the filter shaker assembly mounting knobs (13). Lift the filter shaker assembly (11) to access the filter panel.
5. Lift the dust filter (12) and remove it from the machine.
6. Clean the filter using one of the methods below:
Method "A"
Vacuum loose dust from the filter. Then gently tap the filter against a flat 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 filter. Then blow compressed air (maximum pressure 6 Bar) into the clean side of the filter (in the
opposite direction of the airflow).
Method "C"
Vacuum loose dust from the filter. Then soak the filter in warm water for 15 minutes, then rinse it under a gentle stream of water
(maximum pressure 2.5 Bar). Let the filter dry completely before installing it back into the machine.
NOTE
For proper drying, lay the filter horizontally on two spacers to allow the air to flow under the filter.
NOTE
For a better cleaning, it is allowed to wash the filter with water and non-lathering detergents.
This provides better quality cleaning but reduces the life of the filter, which will have to be replaced more frequently. The
use of inadequate detergents can damage the filter.
7. Install the filter in the reverse order of removal and note the following:
• Install the filter with the wire gauze up.
• If the filter gasket is damaged or missing, it must be replaced.
NOTE
Before replacing filter clear debris from dust plate located under filter.
Check that the debris skirt at the rear of the dust plate swings freely.
