4. Apply enough clean oil to lightly coat the lter (Fig.
25).
5. Squeeze the lter to spread and remove excess oil
(Fig. 26).
6. Replace the air lter in the air lter/mufer cover
(Fig. 23).
NOTE: Operating the unit without the air lter and
air lter/mufer cover assembly, will VOID the war-
ranty.
Installing the Air Filter/Mufer Cover
1. Place the air lter/mufer cover over the back of the
carburettor and mufer.
NOTE: The choke lever must be in position B (Fig.
22) to install the air lter/mufer cover.
2. Insert the four (4) screws into the holes in the air
lter/mufer cover (Fig. 22) and tighten them. Use a
at blade or T-20 Torx bit screwdriver. Do not over-
tighten. Do not use excessive force.
REPLACING THE SPARK PLUG
Use a type RDJ8J spark plug (or equivalent ). The cor-
rect air gap is 0.5 mm (0.020 in). Remove the plug after
every 50 hours of operation and check its condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire rmly and pull the cap from the spark plug.
2. Remove any dirt from around the thread. Remove
the spark plug from the cylinder using a 5/8 in. spark
plug wrench and turning it counterclockwise.
3. Replace cracked, fouled or dirty spark plugs. Set the
air gap at 0.5 mm (0.020 in) using a feeler gauge
(Fig. 27).
4. Install a correctly gapped spark plug in the cylinder
head . Tighten the spark plug using a 5/8 in. spark
plug wrench and turning it clockwise until snug. Do
not over-tighten.
If using a torque wrench, torque to 12.3-13.5 Nm
(110-120 in.lb).
