4. Apply enough clean SAE 30 oil to lightly coat the
filter (Fig. 19).
5. Squeeze the filter to spread and remove excess oil
(Fig. 20).

(Fig. 17).
NOTE: Operating the unit without the air filter and air
filter/muffler cover assembly will VOID the
warranty.
Reinstalling the Air Filter/Muffler Cover
1. Place the air filter/muffler cover over the back of the
carburetor and muffler. Align the screw holes.
2. Insert the four (4) screws into the holes in the air
filter/muffler cover (Fig. 16) and tighten.
Do not over tighten.
NOTE: Make sure that the Red EZ-Fire™ lever is
positioned away from the primer bulb.
If the spark arrestor
hood and spark
arrestor screen are not tightened securely,
they could fall off causing damage to the unit
and possible serious personal injury.

SPARK ARRESTOR MAINTENANCE
1. Remove air filter/muffler cover. Refer to Removing
the Air Filter/Muffler Cover.
2. Locate the muffler, but do not remove it. Find the
screw on the bottom of the muffler (Fig. 21). Remove
the screw using either a torx #20 or flat blade
screwdriver.
3. Carefully pry up the left side spark arrestor hood.
Two tabs act as hinges on the right side of the hood.
Flip open the spark arrestor hood like a door and
then pull its tabs out of the muffler slots.
4. Using a small flat blade screwdriver, carefully pry the
spark arrestor screen out from the inside of the spark
arrestor hood.
5. Clean the spark arrestor screen with a wire brush.
Replace it if it is damaged, or if you are unable to
clean it thoroughly.
6. Reinstall the spark arrestor screen snugly back into
the spark arrestor hood.
7. Reinstall the two hood tabs into the two muffler slots
and flip the spark arrestor hood closed.
8. Replace the screw you removed in Step 2 and tighten
it securely.
9. Reinstall the air filter/muffler cover.
