Filters

Filters are extremely important safety components. They
prevent impurities in the fuel and air circuits from entering
important equipment and causing problems.

However, when working in rough conditions, replace the fil-
ters at shorter intervals according to the oil and fuel (sulphur
content) being used.

Never try to clean filters (cartridge type) and use them again.
Always replace with new filters.

When replacing oil filters, check if the old filter contains any
metal particles. If any metal particles are found, please con-
tact your Komatsu distributor.

Do not open packs of spare filters until just before they are to
be used.

Always use Komatsu genuine filters.
Biodegradable hydraulic oil and lubricants
The use of biodegradable hydraulic oils and lubricants based on
synthetic esters with Komatsu machines is permitted. For infor-
mation on products cleared for use and best suited for your
