Air Filter Element Maintenance
1. Remove the air filter cover and the air filter elements
and check for dirt. Clean as described below.
2.
Cleaning:
• For paper filters:
To prevent injury from dust and debris,
wear ANSI‑approved safety goggles,
NIOSH‑approved dust mask/respirator, and
heavy‑duty work gloves. In a well‑ventilated
area away from bystanders, use pressurized
air to blow dust out of the filter. If this does not
get the filter clean, replace it.
• For foam filters:
Wash the filter in warm water and mild
detergent several times. Rinse. Squeeze out
excess water and allow it to dry completely.
Soak the filter in lightweight oil briefly,
then squeeze out the excess oil.
3. Install the cleaned filter. Secure the
Air Cleaner Cover before use.
Spark Plug Maintenance
1. Disconnect spark plug cap from end of plug.
Clean out debris from around spark plug.
2. Using a spark plug
wrench, remove
the spark plug.
3. Inspect the spark
plug:
If the electrode is
oily, clean it using
a clean, dry rag.
If the electrode has
deposits on it, polish
it using emery paper. If the white insulator is cracked
or chipped, the spark plug needs to be replaced.
NOTICE:
Using an incorrect spark plug may
damage the engine. See the Specifications chart
for your Generator for the type and gap required.
4. When installing a new spark plug, adjust
the plug’s gap to the specification on the
Specifications chart. Do not pry against the
electrode, the spark plug can be damaged.
5. Install the new spark plug or the cleaned spark plug
into the engine. Gasket‑style: Finger‑tighten until the
gasket contacts the cylinder head, then about 1/2‑2/3
turn more.
Non‑gasket‑style: Finger‑tighten until the plug
contacts the head, then about 1/16 turn more.
NOTICE:
Tighten the spark plug properly.
If loose, the spark plug will cause the engine
to overheat. If overtightened, the threads
in the engine block will be damaged.
6. Apply dielectric spark plug boot protector
(not included) to the end of the spark
plug and reattach the wire securely.
