Spark Plug
§ Recommended spark plug: F7RTC.
§ Stop the engine and allow it to cool
Warning! Do not use an
incorrectly rated plug. It
is essential to keep the
spark plug in good
condition – clean and
properly adjusted.
Warning! To keep
engine at top
performance spark plug
gap should be
within specified and
carbon built up free.
§ Removing spark plug with a spark plug
wrench.
§ Inspect the spark plug visually. If spark plug
is worn, dirty or has cracks, replace with the
recommended type and heat range.
§ The correct air gap is 0.70 to 0.80 mm
§ Tighten the spark plug
§ After spark plug is tight; torque to 25-30N m.
Warning! An incorrectly
tightened spark plug
may result in poor
engine performance and
permanent engine
damage.
Combustion deposits
We recommend that you should remove
combustion deposits from the cylinder, cylinder
head, top of piston, and around valves after
100-300 hours usage.
Muffler
Warning! If engine just
running down, do not
touch muffler. Allow it to
cool before operation.
Transporting and storage
When storing engine for more than 30 days:
§ Store in a dry and clean area
§ Run engine until fuel tank is empty and
engine stops or add gasoline preservative and
running engine after adding for several minutes
to circulate preservative.
Warning! Gasoline is
flammable. Fuel or fuel
vapors may explode.
Keep sparks and open
flames from the working
area.
§ Change engine lubrication oil.
§ Clean the exterior surfaces of the engine.
§ Remove spark plug, pour one teaspoon of
fresh engine oil into cylinder. Re-install spark
plug without the spark plug wire attached. Pull
starter rope slowly several times to distribute
the oil in the engine.
§ Slowly pull start handle until the resistance
is reached, then stop pulling. At that point,
valves are closed, that will prevent dust and
rust from entering cylinder.
§ Cover engine well to prevent dust.
Warning! When you
service the engine,
inspect the blade, or
clean the underside of
the housing: make sure
to tip the engine with the
spark plug up.
Transporting or tipping
the engine with the spark
plug down will cause:
