SPARK PLUG MAINTENANCE
This Water Pump will work more efficiently with a properly functioning spark plug. The spark plug should be
replaced every 100 hours of use.
To check or replace the spark plug:
1. Disconnect the spark plug wire from the spark plug.
2. Clean around the spark plug using a wire brush before removing
the plug using a spark plug wrench.
3. Check the spark plug for foreign substances. If moisture is present,
wipe it off using a clean shop towel. If there are deposits
present (A, Figure 6), use a fine grit sand paper to remove them.
If there is structural damage to the spark plug, replace it with a new
one (B, Figure 6).
4. When installing the new plug, replace it with a Type F6TC and
set the gap to 0.60 – 0.80mm.
