Manual Extract: Cab air filters – Cleaning

Before servicing the filters, switch off the blower, close the roof hatch, all windows and one door. Slam the final door and the resulting back pressure will dislodge most of the loose dirt from the underside of the filters.

1. CAUTION
Eye injury hazard!
Wear protective goggles when using compressed air.
Failure to comply could result in minor or moderate injury.

Remove the filter elements. The fresh air filters, Figure 1 (Deluxe cab), Figure 2 (low profile cab) have a prefilter element fitted that is designed to catch most of the dust/chaff. This prefilter is part of the filter and should be pulled out from the underside and cleaned first, then pushed back in.

The recirculation filter, Figure 3, is fitted with a pull tab. This should be used to remove the filter. The filter pleats should never be used to remove the filter as damage will result.
Blow the dust from the upper surface through the element to the underside. Clean by blowing with compressed air not exceeding 2 bar (29 psi). Hold the nozzle at least 30 cm (12 in) from the element to prevent damage to the pleats.
Care should be taken when using compressed air as this may damage to the filter.

2. Clean all filter chambers with a damp, lint free cloth.
Replace the filter elements with the rubber seal uppermost and install the covers again.
