MAINTENANCE

WARNING:

When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

WARNING:

Always wear eye protection marked to comply with ANSI Z87.1. Failure to do so could result in objects be- ing thrown into your eyes, resulting in possible serious injury.

Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at an authorized service center.

GENERAL MAINTENANCE

Keep the generator in a clean and dry environment where it is not exposed to dust, dirt, moisture, or corrosive vapors. Do not allow the cooling air slots in the generator to become clogged with foreign material such as leaves, etc.

Do not use a garden hose to clean the generator. Water en- tering the fuel system or other internal parts of the unit can cause problems that will decrease the life of the generator.

To clean the unit:

Use a soft bristle brush and/or vacuum cleaner to loosen and remove dirt and debris.

Clean air vents with low pressure air that does not exceed 25 psi.

Wipe the exterior surfaces of the generator with a damp cloth.

CHECKING/CLEANING AIR FILTER

See Figure 13.

For proper performance and long life, keep air filter clean.

Release latches on left side of air filter cover. Remove cover and set aside.

Remove the filter element.

If the filter element is dirty, clean with warm, soapy water. Rinse and let dry.

Apply a light coat of engine lubricant to the element, then squeeze it out.

Replace the element in the air filter unit.

Replace the air filter cover and latch to secure.

NOTE:  Do not run the generator without the air filter. Rapid engine wear will result.

CHANGING ENGINE LUBRICANT

See Figure 14.

Remove the oil cap/dipstick.

Place a container underneath the oil drainage bolt to collect used lubricant as it drains.

Unscrew the oil drainage bolt and remove.

Allow lubricant to drain completely.

Reinstall the oil drainage bolt and tighten securely.

Refill with lubricant following the instructions in the

Checking/Adding­Lubricant section.

Reinstall the oil cap/dipstick.

NOTE:  Used lubricant should be disposed of at an ap- proved disposal site. See your local oil retailer for more information.

SPARK PLUG MAINTENANCE

See Figure 15.

The spark plug must be properly gapped and free of deposits in order to ensure proper engine operation. To check:

Remove the spark plug cap.

Clean any dirt from around base of spark plug.

Remove spark plug using wrench (not included).

Inspect spark plug for damage, and clean with a wire brush before reinstalling. If insulator is cracked or chipped, spark plug should be replaced.

NOTE:  If replacing, use the following recommended spark plugs or equivalent:  NGK BR-6HS or Champion RL86C.

Measure plug gap. The correct gap is 0.028−0.031 in.

(0.7-0.8 mm). To widen gap, if necessary, carefully bend the ground (top) electrode. To lessen gap, gently tap ground electrode on a hard surface.

Seat spark plug in position; thread in by hand to prevent cross-threading.

Tighten with wrench to compress washer. If spark plug is new, use 1/2 turn to compress washer appropriate amount. If reusing old spark plug, use 1/8 to 1/4 turn for proper washer compression.

NOTE:  An improperly tightened spark plug will become very hot and could damage the engine.
