7.4 Replacing oil filter
1. Remove the M8 screws on the exhaust port cover
。
2. First remove the three filter element springs and W-type filter element holder from
the fuel tank, and then pull the three filter elements out of the fuel tank.
3. Make sure that the new oil mist filter is fitted with an O-ring (opposite the
overvoltage protection switch) and lubricated with vacuum grease.
4. Check the O-ring of the exhaust port cover for deformation and damage. If so,
replace it with a new one.
5. Insert the new oil mist filter element into the correct position in the fuel tank. The
long strip on the cylinder surface of the filter element should be installed directly below the
filter element to ensure that the filter element spring is behind the W-shaped filter element
bracket.
6. Slowly insert the two positioning pins on the exhaust port cover into the
corresponding holes in the W-shaped filter element bracket, and then screw in the M8
screws.
7.5 Cleaning the Dirt Trap
A dirt trap for coarse particles is located in the intake flange of the pump. It should be
kept clean to avoid reduction of the pumping speed.
Remove the air inlet flange, remove the retaining spring and Y-piece from the inside,
take out the wire screen, and clean it.
Then, reinstall in the reverse order, and if necessary (deformed or damaged O-ring),
replace the O-ring.
Install the air inlet flange.
Important information
Depending on the process involved, dangerous substances may escape from the pump
and oil. Take the appropriate precautions.
When disposing of used oil, please observe the relevant environmental regulations!
