Spark Plug
1)
Remove the spark plug and inspect it
each time you change the oil. The
electrodes should be kept clean and
free of carbon. The presence of
carbon or excess oil will greatly reduce
proper engine performance. If
possible, check the spark plug gap
(area between electrodes) using a wire
feeler gauge. This specification is 0.6
– 0.7 mm.
2)
Before installing spark plug, coat
threads lightly with graphite grease if
possible to ensure easy removal in the
next time spark plug needs inspection.
3)
It is recommended to replace the spark
plug at least once a year to ensure easy
starting and good engine performance.
Chain Lubrication and Adjustment
For optimum chain life, lubrication with a spray on chain lubricant should be performed
on a regular basis. Do not use other oils.
A new chain will stretch within the first few
hours of use and therefore will require
adjustment. The first chain adjustment
should be made after first 2 hours of use.
If the chain has more than 1/2” of slack or
“flex” then it will require to be adjusted.

Adjust Nut (2) until the proper chain
tension is achieved.
