Changing the Air Filter
To change the Air Filter, remove the top GRP cover and Filter Clamp Disk (Fig 10).
The element can then be lifted out and replaced. Paper elements (Part No. 6289992000-2)
should be changed every 6 months.
Pleated aluminium elements (Part No 6289892000-2) should be inspected every 6 months
and any blockage can be blown out with a compressed air line.
IMPORTANT: When the element has been removed, ensure that nothing can fall into the
machine through the inlet port.
To grease the drive shaft bearing caps it will be necessary to remove the GRP cover
plate (Fig 11) by unscrewing the 10 socket head screws. Two ‘elbow’ type grease nipples
are located on extension shafts above the drive shafts / bearing caps. Drum recommends
they are greased (Aeroshell No.5) once a year or every 500 hours of operation, whichever
is the sooner. When applying grease it is important to note that old grease followed by the
new will be expelled past the shaft seals when bearing housings are full. Ensure that this
excess grease is cleaned off to avoid contamination of the drive belts.
