Air Filter Cleaning
A dirty air filter will restrict air flow to the carburetor, reducing engine
performance. If you operate the pump in very dusty areas, clean the
air filter more often than specified in the MAINTENANCE SCHEDULE
(page 8).
1. To clean the paper filter element, tap the element lightly several
times on a hard surface to remove excess dirt, or blow compressed
air (not exceeding 207 kPa) through the filter element from the
inside out.
Never try to brush the dirt off; brushing will force dirt into the paper
fibers. Replace the paper element if it is excessively dirty or
damaged.
2. To clean the foam filter
element, wash the
element in a solution of
household detergent and
warm water, then rinse
thoroughly, or wash in
nonflammable solvent.
3. Allow the foam filter
element to dry
thoroughly.
4. Soak the foam filter element in clean engine oil and squeeze out
the excess oil.
NOTICE
Excess oil will restrict air flow through the foam filter element and
may transfer to the paper filter element, soaking and clogging it.
5. Reassemble the air filter as shown.

Spark Plug Service
Recommended Spark Plug: NGK - BPR6ES
NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits.
Allow the engine to cool before servicing the spark plug.
1. Disconnect the spark
plug cap [1] and
remove any dirt from
around the spark plug
area.
2. Use a spark plug
wrench [2] to remove
the spark plug.
3. Visually inspect the
spark plug. Discard it if
the insulator is
cracked, chipped, or
fouled.
4. Measure the plug gap
with a suitable gauge.
Correct as necessary
by carefully bending
the side electrode.
Plug gap:
0.7 ~ 0.8 mm
5. Check that the spark
plug washer is in good
condition, and thread the
spark plug in by hand to
prevent cross-threading.
6. After the spark plug is
seated, tighten with a
spark plug wrench to
compress the washer.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer.
If reinstalling a used spark plug, tighten 1/8 - 1/4 turn after the
spark plug seats to compress the washer.
NOTICE
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
7. Reconnect the spark plug cap.
