To ensure a long operating life for a modern, turbo‐charged engine,<br />
maintaining the good condition of the air filter is essential.<br />
► Turn off the engine.<br />
Varoitus! Varning! Warning!<br />

► Remove the filter cover fasteners and the cover.<br />
► Remove the filter element (3) by rotating and pulling it out from the case.<br />

Huomaa! Notera! Note!<br />
Do not remove the safety element (2) from its place.<br />
► Clean the inside of the cover (4) and the filter element case (1) by wiping.<br />
► Check the filter element (3) and seals. If the element looks tidy and is in good<br />
condition, you can clean off the loose dust and dirt by lightly knocking on it.<br />
If the element is dirty or damaged, it must definitely be replaced.<br />
► Clean and check the dust pocket (5). If the dust pocket is damaged or does<br />
not close properly, replace it with a new one.<br />
Info!<br />
If the filter element is damaged, the safety element must also be<br />
replaced.<br />
Otherwise, check the condition of the safety element, but do not remove<br />
it if it is in working order.<br />
Filter manufacturers do not recommend cleaning the filter element with<br />
compressed air, since compressed air can easily tear the fibres of the filter<br />
paper and ruin a good filter element without leaving a visual indication of<br />
this.<br />
► If you must use compressed air, use very low pressure and direct the air from<br />
the inside of the filter outwards. Limit air pressure to 2–3 bar, and do not<br />
press the air nozzle against the filter paper or too close to it.<br />
► Inspect the condition of the filter element’s rubber seals.<br />
► Install the filter element and protective cover in the reverse order.<br />
Info!<br />
The safety element must be replaced no later than when the main<br />
element has been cleaned five times.<br />
Replace the safety element (2) when necessary:<br />
► By rotating and pulling it out.<br />
► Clean the case.<br />
► Press a new element in by rotating it.<br />
