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.
– Clean the filter in a well-ventilated area.
– Wear appropriate dust mask to avoid breathing in dust.
– Do not puncture the filter.
1. Drive the machine on a level floor, engage the parking brake and turn the ignition key (57) to "O".
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"
Collect 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"
Collect 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"
Collect 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.

DUST FILTER MAINTENANCE (CLOSED POCKET FILTER)

The closed pocket filter is basically maintenance free. The only periodic maintenance required is to run the filter shaker on a daily
basis by pressing the lower part of the switch (59).
NOTE
The filter shaker should only be run when the hopper is lowered.
