TO SERVICE PRE-CLEANER
2. Remove foam pre-cleaner from cover.
3. Wash it in liquid detergent and water.
4. Squeeze it dry in a clean cloth. Allow it
to dry.
5. Saturate it in engine oil. Wrap it in
clean, absorbent cloth and squeeze to
remove excess oil.
TO SERVICE PAPER CARTRIDGE
° Replace a dirty, bent, or damaged car-
tridge. Handle new cartridge carefully;
do not use if the rubber seal is dam-
aged.
NOTE: Do not wash the paper cartridge
or use pressurized air, as this will damage
the cartridge.
1. Carefully remove cartridge and grid to
prevent debris from entering carbu-
retor. Clean base carefully to prevent
debris from entering carburetor.
2. Separate the grid from paper cartridge
and gently tap pleated side of cartridge
to dislodge dirt. Never try to brush off
dirt; brushing will force dirt into the
fibers of the paper element.
3. Install the grid over the paper cartridge,
then install the assembly into the air
cleaner base. The grid must be placed
between the foam pre-cleaner and
the paper cartridge to prevent oil from
transferring to the paper element.
4. Reinstall the pre-cleaner (cleaned and
oiled) into the cover.
5. Reinstall air cleaner cover and secure
by tightening knobs.
