Air Filter Element Maintenance

y fet Sa

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.

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 spark plug boot protector to the end of the spark plug and reattach the wire securely.
