16 AIR FILTER MAINTAINENCE
16.1 MOTOR SUCTION FILTER
With model VPM 3400, the intake air is cleaned by an air filter with 2 inserts before it enters
the motor. In order to ensure the required filtration, it is necessary to keep both filters clean.
- As the dust filter is a type of dry filter, oil must never be added to the filter.
- If the inner portion of the air filter housing is dirty or wet, clean it with a clean
piece of cloth.
- Try not to touch it, only during cleaning.
- If dust has settled on the part, blow it out with compressed air from the inside.
Use a min. air pressure of 7 bar or 99 psi.
- If the part is brought into contact with carbon or oil, immediately replace the
filter.
- The filters are replaced after 150 operating hours.
IMPORTANT: Make sure the brackets for tightening various parts of the filter are tightened
properly. If they loosen up, dust and dirt can be sucked in and damage the cylinder liner and
piston rings.
