CHANGING THE FUEL FILTER AND FILTER ELEMENT
• Danger of fire! Fuel may ignite on hot surfaces!
Only change the filter elements if the engine has suffi-
ciently cooled down. Stay away with open fire or sparks
while handling with fuel. Do not smoke.
1. For maintenance operations, park and secure machine as
described in chapter "Preparing the Machine for Mainte-
nance".
2. Clean the area around the fuel filter (1).
3. Unscrew the filter element counterclockwise with the filter
screwdriver.
4. Clean the filter head.
5. Fill up the new filter element with clean fuel.
6. Lubricate the sealing faces of the filter element lightly with
engine oil.
7. During reassembly, re-tighten the filter element manually,
until the seal is fitting. Then re-tighten the filter element.
(Consider the specifications of the filter manufacturer on the
filter).
8. Then purge the fuel system.
(see section "Bleeding the Fuel System").
