Air Filter Maintenance; Spark Plug Maintenance - Buffalo Sportsman Series Operating Instructions Manual

Wear ANSI-approved safety gear, including safety goggles and heavy-duty work gloves when
servicing this Water Pump.
This Water Pump will work more efficiently with a clean air filter. The air filter should be checked every 25
hours of use, regardless of workload, and replaced every 100 hours regardless of workload.
To clean or replace the air filter:
1. Remove the air filter cover, which is held in place by a nut and is located
on top of the Water Pump. (A, Figure 5)
2. Remove the air filter.
3. If the air filter is paper, use a vacuum to remove any trapped dirt. If this
doesn't work, replace with a new filter.
4. If the air filter is foam, wash the filter in warm water and a mild detergent
before rinsing thoroughly.
5. Squeeze out excess moisture and dry completely.
6. Briefly soak the filter in lightweight oil, squeezing out the excess, before
replacing it in the Water Pump.

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.
