Cleaning Polyurethane Band
1. Remove air cleaner element and remove polyure­
thane band from paper element.
2. Inspect the polyurethane band for tears and replace if
necessary. If not torn, wash polyurethane band in
kerosene or mineral spirits; then squeeze out excess
solvent (fig. 7A).
NOTE: Never use a hot degreaser or any sol­
vent containing acetone or sim ilar solvent.
3. Dip element into light engine oil and squeeze out ex­
cess oil.
NOTE:
Never shake, swing or wring the ele­
ment to remove excess oil or solvent as this
may tear the polyurethane material. Instead,
"squeeze" the excess oil from the element.
4. Check the paper element as previously outlined
(without the polyurethane band).
Install the polyurethane band around the paper ele­
ment and install the air cleaner element.
