5.4 AIR CLEANER

good clean air conditions. Service and replace element
more frequently under dusty or dirty conditions.
To clean the element remove and tap lightly on a flat
surface to remove loose surface dirt. Replace element
if dirt does not drop off easily. Do not wash or dry
elements in any liquid or attempt to blow dirt off with air
hose as this will puncture the filter element.
Carefully handle new element. Do not use if gasket
surfaces are bent or twisted. Check the following when
installing new element (Figure 9).
1. Back plate must be securely tightened to
carburetor. Replace back plate if bent or cracked.
2. Gasket surfaces of element must be flat against
back plate and cover to seal effectively.
3. Washer must be in place between cover and wing
nut to seal and prevent unfiltered air from entering
through hole in cover. If washer is not used, make
sure wing nut (special) properly seals area around
cover hole.
4. Wing nut must be finger tight.
WARNING: Do NOT touch parts which are
hot. Allow parts to cool before servicing.
