13.5.4 Air Filter Cleaning Procedure:
1) Tap filter gently, and then brush outside of filter with a soft bristle brush, to remove
loose dirt.
2) Wash the outside of the filter with mild liquid soap and warm (maximum 40°C) water,
by agitating the filter in the solution.
3) Ensure that the contaminated solution does not come in contact with the inside
surfaced of the filter.
4) Rinse off the filter, from the inside, with clean low pressure water – from a tap or a
similar supply. Rinse thoroughly to ensure all soap is removed.
5) Examine filter and if necessary repeat stages 2 and 3.
6) Shake off all surplus water and allow filter to dry naturally.
7) Re–oil element: Aerosol – Spray one pass per pleat into each pleat, from the
outside
Liquid – One bead of oil every 6 mm down each pleat.
8) Check that no white patches remain after 10 minutes.
9) Re–oil where necessary. A red dye in the oil clearly shows those areas that have been
correctly oiled.
10) Reinstall air filter and tighten all clips and fittings.
NOTE !
Do not use harsh detergents, caustic solutions, solvents, fuel, steam, or
pressure washers!
CAUTION !
Excess heat (over 40°C), or compressed air will damage the filter:
Do not use without re – oiling!
Only use filter oil from Austro Engine GmbH or K & N!
CAUTION !
Once the filters have been removed, the associated duct and fan impeller
should be inspected for dust or debris of any type. If found, it indicates
inadequate filter care or a damaged filter and could have serious consequences.
Advice should be sought from Austro Engine GmbH on the significance of this
material and the effect it may have on the engine. Either or both filters should be
replaced if their condition is suspect.
