Air Filter - Volvo EC35 Operator's Manual

Air filter

If control light (7) in the instrument panel lights up the filter
must be immediately cleaned or, if necessary, replaced.
Check the air lines (filter - engine) for leaks during every main-

tenance. Replace defective parts and tighten loose hose
clamps.
IMPORTANT! The air filter maintenance intervals depend on
the amount of dust in the air and can therefore not be deter-
mined precisely. Under extremely dusty conditions daily
cleaning may be required.
Cleaning the dust valve
Clean the dust valve every 10 operating hours.
1 Empty the dust valve (9.1) by squeezing the slot together.
2 Remove possible dust deposits by squeezing the upper part of
the valve.

cally against the palm of your hand or against a flat and soft sur-
face.
