warning light on the instrument panel illuminates.
2-3-3-1
1 Park the machine on firm, level ground and stop the
engine. If the vehicle has a manually operated load
bay, remove the starter key.
2 Raise the load bay. If your vehicle has an electric
tipper, ensure that the starter key is removed.
3 Undo the two retaining clips 6-A holding the cover
and remove the element. Do not tap or knock the
element as you remove it.
4 Clean the inside of the canister 6-B and dust valve 6-
C .
5 Prior to fitting a new element, smear the seal on the
end of the element with grease. Temporarily insert the
filter element into the canister ensuring its correct
location. Withdraw the element and check that there
is a continuous grease witness mark around the base
of the canister. This shows that the canister has not
been distorted which would allow unfiltered air to
bypass the element. Refit the element and cover.
Check all air hoses for condition and security.
