DUST FILTER CLEANING AND INTEGRITY CHECK

1. With the machine on level ground, activate the brake pedal (26, Fig. C) (if present), or block the wheels.

2. Turn the ignition key (2, Fig. B) to the “0” position.

3. Disengage the hopper latch (18, Fig. C).

4. Using the handle (19, Fig. C) remove the hopper (17, Fig. C) from the machine.

5. Rotate the filter clamp (1, Fig. L) upward (approximately 90°) and let the top of the filter frame (2) rotate outward.

6. Pull the dust filter (3, Fig. L) upward to remove it.

7. In a well-ventilated, outdoor area, clean the filter by gently tapping the side of the filter (1, Fig. M), opposite to the wire screen (2) on the ground.

8. Finish cleaning the filter by using compressed air (3, Fig. M) of max. 6 bars ( 87 psi), blowing only from the side protected by the wire screen (2, Fig. M). According to the type of filter, take care of the following cautions: – Paper filter (standard): do not use water or

detergents to clean it; the filter can be damaged.

– Polyester filter (optional): to clean it, follow

the instructions mentioned in number 7 above. For better cleaning, wash the filter with water and non-foaming detergents. This type of washing will clean the filter better, but it reduces the life of the filter. The use of inadequate detergents can damage the filter. Check the filtering medium body for cuts or holes.

9. If necessary clean the filter compartment rubber seal (4, Fig. L) along its perimeter and check its integrity. If necessary replace it.

10. Install in the reverse order of removal.

NOTE:

Besides the standard paper filter, optional polyester filters are available. The following procedure is applicable to each type of filter.

NOTE:

Reinstall the filter with the wire screen (2, Fig. M) facing the front part of the machine.
