Spark plug recommendation: TORCH CMR5H, NGK CMR5H, CHAMPIONS R27C
1 Unplug the spark plug pipette or cap by pulling outward (as shown with the arrow
in the figure below).
2 Using the spark plug spanner, extract the spark plug by unscrewing it from the
engine (turn counter clockwise)
3 Inspect the spark plug visually. Replace with a new one if the insulator is cracked
or chipped. Clean the electrode with a fine wire brush to clean the filth deposits.

5 Measure the electrode distance with a gauge. Normal value 0.6 - 0.7 mm. Adjust
the opening carefully if the value is not correct.
6 Carefully replace the spark plug, begin screwing it with your hand to avoid
damaging the threads. Once the spark plug is threaded to the end of the thread,
make the final tightening:
 New plugs 1/2 turn using the spark plug spanner.
 Used spark plugs 1/8 to 1/ 4 turn with the spark plug spanner.
7 Reinstall the spark plug pipette or cap and close the access cap by fastening with
its screw.
NOTE: The spark plug must be tightened firmly. A loose spark plug may
overheat and even damage the engine. Similarly, overtightening may damage the
spark plug and, worse, the engine cylinder head thread.
