engages the brake system, but not yet.

e. Remove the outer foam from filter and make it moist evenly with a few drops of fuel. If the vehicle
will be operated in an area with fine dust, use filter oil or caster oil instead of fuel and make both the
inner and outer foam moist. It is important that the foam is only moist to trap dirt and allow air passage.
With the foam too wet, limited air can pass through; therefore, limiting engine performance.
f. Install the filter boot onto the engine carburetor and make sure the air cleaner boot is securely
fastened with a zip-tie.
