Masport Utility 460 ST S18 - 625 Questions & Answers

The plastic filter cover is on the front left-hand-side and is a press-fit that unclips. You should check it each time before using the mower. You shouldn't need to change it. It is surrounded with a ring of sponge foam that is wet with some engine oil. That picks the dust as the air is sucked into the filter and engine. Tap the paper air filter against a hard surface [the mower] to knock any loose debris from the filter. Apply a smear of clean oil to the foam before reassembly and fitting.

Thank you for your response to my question about Masport mower air filter. I just had mower serviced and mowed my back “lawn”. A lot of the “lawn” is dusty patches so I may need to check air filter again and again. Good to now know how to do it. Thank you. Peter.
