1. Soak the filter
Put three liters of tap water, as hot as possible in the special purpose designed cleaning tub. Add 100ml of Bio Dirt Remover to the water (One filter needs 100ml of Bio Dirt Remover)
Fully immerse the dirty filter (wear
protective or disposable gloves and be careful not to burn your hands), and let it soak for ten to fifteen minutes.
2. Squeeze the filter
Squeeze the filter several times (do not wring!), repeat this procedure until all the dirt has disapeared.
3. Wash the filter
Wash the filter with clean, cold tap water
until all the soap residue has been removed. Leave the filter out to dry, under a piece of cloth. Once the filter is dry, it is ready to be pre-oiled again.
TIP: Oiling the filter without allowing it to dry sufficiently will trap some of the moisture.
4. Oil the filter
Soak filter in BIO Liquid Power Filter Oil, making sure to saturate the entire filter, coating the filter uniformly. Be sure to apply oil to the inside and outside of the filter.
TIP: Don't oil your air filter right before riding. Preoil the filter at least 24 hrs before riding to allow the oil to evenly penetrate the pores and allow the thinning agent to evaporate. A recently oiled filter will cause rich conditions.
5. Squeeze excess
Squeeze excess oil out of the filter so that a light coat of oil remains. Continue to massage until the filter is evenly coated.
7. Install the filter
Install the cage into the filter and install filter into airbox. Before installing check carburetor boot for dirt.
6. Dry the filter
Leave the filter out to dry in a well-ventilated area, preferably outside in the open air under a piece of cloth. After approximately 2 hours, the filter is ready to be used. Store pre-oiled filters in the resealable Twin Air bag (or an airtight plastic bag) and in a dark spot.
MORE FILTER CARE TIPS
Clean air filter cage and bolt
Using contact cleaner, spray the filter cage and bolt to remove old oil and dirt.
Clean sealing ring
Spray contact cleaner on a rag or towel and wipe the sealing ring of the airbox to remove dirt and oil residue. Look inside the airboot to make sure no dirt fell into the boot when you removed the filter.
Install your Twin Air Airbox Cover before you wash your bike or ATV. With the Airbox Cover installed, you can wash out your airbox without getting dirt or water into your airboot.
