-To service the pre-cleaner, carefully remove and wash in a solution of liquid detergent and water. Allow to air dry thoroughly before replacing.

-Clean the cartridge by tapping gently on a flat sur- face. If very dirty, replace or wash in a solution of non-foaming detergent and warm water. Rinse thor- oughly with running water from the mesh side until the water is clear. Allow the cartridge to stand and air dry thoroughly before replacing. Do not use petrole- um solvents during cleaning as this will cause the car- tridge to deteriorate. Do not use pressurised air as this may damage the cartridge. Do not oil the cartridge.

-After servicing, install the pre-cleaner and cartridge in the cover. Insert the tabs on the bottom of the cover into the slots in the bottom of the base (5). Tilt the cover upwards and securely tighten the screw to the base.
