Cab Air Filter
As a standard option dust filters are fitted. The filters are housed in the cab roof above the
doors. Regular servicing of these cab filters should be carried out, particularly when
working in dusty conditions. Remove grills and two filters to clean. Clean them with
compressed air directed from the clean side (this applies to the standard dust filter only). .
Replace cab air filters as necessary
Note: as an option carbon filters are available for when spraying hazardous chemicals, as
recommended to comply with the Health and Safety Executive. The carbon filters meet
the recommendations for standard pesticides as detailed in the HSE publication PM74
Sept. 1990
WARNING The cab cannot fully protect against inhaling vapour, aerosol
or dust, when operating in an environment where pesticides are present, wear
appropriate clothing and if pesticides instructions call for it, a respirator in
and outside the cab.
Installation (applies to both filter types)
1. Wear a dust mask and gloves when removing the old filter and cleaning the
housing.
2. Carefully remove the old filter.
3. Clean any dust and dirt from the filter housing.
4. Inspect the filter gasket ensure that it is undamaged.
5. Insert the filter carefully and ensure that it seats correctly.
6. Refit the grills and secure.
Changing the filter
1. The carbon in the filter will only remain effective for up to a maximum of 6 months,
whether the machine is being used or not, as the carbon degenerates when in
contact with the air. The carbon filters should be replaced after 250 – 300 hours of
use.
2. The filters are not cleanable DO NOT attempt to blow them out with compressed
air. DO NOT attempt to wash them. Both methods will destroy the integrity of the
filter.
3. When not in use, store the filters in a sealed plastic bag in a dry place.
4. Consult your waste authority for advice on the safe disposal of used filters.
Hydraulic Hoses
Inspect hoses and fittings for damage or leaks. Check the cover for signs of abrasion,
blisters, nicks, cracks, cuts, hardness or colour changes.
Avoid fluids under pressure coming into contact with the skin. Relieve system
pressures first before working on high pressure pipes, fittings, etc. be aware that
the machine has hydraulic accumulators for the braking circuit.
