Air Filter Element Maintenance
1. Remove the air filter cover and the
air filter elements and check for dirt.
Clean or replace as described below.
2.
Cleaning:
• For “paper” filter elements:
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 air filter. If this
does not get the filter clean, replace it.
• For foam filter elements:
Wash the element 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 new filter or the cleaned filter.
Secure the Air Cleaner Cover before use.
Spark Plug Maintenance
1.
Spark
Plug
Cap
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.
Use only NHSP®/Torch® F6TC spark plug.
NOTICE:
Using an incorrect spark
plug may damage the engine.
4. When installing a new spark plug, adjust the
plug’s gap to the specification on the Technical
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 tighten about
1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until the plug
contacts the head, then tighten 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.
