Maintaining your engine
Engine Oil Replacement
Oil crankcase capacity: 0.6 litres.
Engine oil should be replaced after the first 20 hours of op-
eration or after the first month of use, it should be replaced
every 100 hours or 6 months after. To replace engine oil;
1) Loosen the oil gauge dipstick (B) Fig.29.
2) Place an oil pan underneath drain hex. bolt (A),
remove hex. bolt (A) and drain oil.
3) Once all the oil has completely drained, retighten the
hex. bolt (A).
Recommended Engine Oil
It is recommended to use SAE 10W30 4-stroke gasoline engine oil. For cold weather (below
-15ºC) use SAE 5W30.
4) Fill with clean engine oil through the oil gauge dipstick hole, fill then check oil level until
the oil level reaches 3/4 up the dipstick or until it reaches the bottom lip of the dipstick hole
as shown in illustration above.
Inspecting, Replacing or Cleaning Spark Plug (F6RTC or equivalent)
The spark plug should be checked every 100 hours of operation or every 6 months. To re-
place or clean spark plug;
1) Dismantle the spark plug cap (A) Fig.30 by pulling it off the spark plug (B). Using a spark
plug wrench, undo the spark plug by turning it counterclockwise.
2) Check to see if there is carbon sediment build-up, if so just remove it. If the carbon
sediment is excessive, replace the spark plug.
3) Measure the electrodes clearance. See Fig.31. The spark plug electrode clearance
should be between 0.7-0.8mm. If the clearance exceeds 0.8mm, replace the spark plug
with an CH F6RTC or equivalent (NGK BPR6ES, Champion RN9YC).
4) Reinstall spark plug in the reverse order.
Cleaning Deposit Cup
1) Push the fuel valve to the closed (left) position.
2) Remove centre deposit cup bolt (B) Fig.32 using a wrench. Place a pan under the
deposit cup to catch any gasoline inside the carburetor.
3) Remove deposit cup (A) Fig.32 and o-ring (C), wash both in solvent.
4) Reinstall parts in reverse order.
