Troubleshooting and Maintenance Guide for the Hyundai HY2800L-2 Petrol Site Generator

Maintenance & Care

Follow the maintenance intervals shown below. More frequent service is required when operating in adverse conditions.

General recommendations:

• The warranty of the generator does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the generator as instructed in this manual. Some adjustments will need to be made periodically to properly maintain the generator.
• All adjustments in the Maintenance section of this manual should be made at least once each season. Follow the requirements in the “Maintenance Schedule.”

IMPORTANT: Once a year replace the spark plug and the air filter. A new spark plug and a clean air filter helps the engine run better and last longer.

Generator maintenance:

• Generator maintenance consists of keeping the unit clean and dry. Operate and store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air slots in the generator must not become clogged with snow, leaves, or any other foreign material. DO NOT use the machine where it can become exposed to rain, snow, sleet or any other type of moisture. 
• Check the cleanliness of the generator frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior surface.

CAUTION: Never insert a finger, object or tool through the air cooling slots, even if the engine is not running.

NOTE: DO NOT use a garden hose or pressure washer to clean the generator. Water can enter the engine fuel system and cause problems. In addition, if water enters the generator though the cooling air slots, some water will be retained in voids and crevices of the rotor and stator winding insulation which can cause electrical shorts circuits and damage the alternator. Water and dirt build up on the generator internal windings will eventually decrease the insulation resistance of these windings.

Cleaning the external of the generator:

• Use a damp cloth to wipe the exterior surfaces.
• A soft, bristle brush may be used to remove dirt, oil etc.
• A vacuum cleaner may be used to pick up loose dirt and debris.
• Low pressure air (not to exceed 25 psi) may be used to blow away dirt.
• Check cooling air slots and openings on the generator. These openings must be kept clean and unobstructed. 

Engine Maintenance:

WARNING: When working on the generator, you MUST always disconnect the spark plug HT cable from the spark plug and keep the cable away from the spark plug. The fuel tap should also be in the OFF position.

Oil change:

CAUTION: Hot oil may cause burns. Allow engine to cool before draining oil. Avoid prolonged or repeated skin exposure to used oil. Thoroughly wash exposed areas with soap.

• Before starting you MUST allow the engine to cool down slightly. While the engine is cooling down;
• Clean area around oil drain plug.
• Remove oil drain plug and dipstick from the engine to drain oil completely into a suitable container.
• When oil has completely drained, refit the oil drain plug and fully tighten.
• Fill the engine with recommended oil. SA15W40
• Wipe up any spilled oil.
• Dispose of used oil at a proper collection center.
• Refit the dipstick.

Spark plug replacement:

• Use spark plug F6TC, BPR4ES or Champion RN14YC. Replace the plug once each year. This will help the engine to start easier and run better.
• Stop the engine and remove the HT lead from the spark plug.
• Clean the area around the spark plug and remove it from the cylinder head.
• Set the spark plug’s gap to 0.70-0.80 mm (0.028-0.031 in.).Install the correctly gapped spark plug into the cylinder head and torque to 15 ft/lbs.

Spark arrestor service: (Spark arrester fitment may vary model to model.)

• Shut off generator and allow the engine and muffler to cool down completely before servicing spark arrestor (located on the back of the muffler).
• Remove the clamp and spark arrestor screen.
• Clean the spark arrestor screen with a small wire brush.
• Replace the spark arrestor if it is damaged.
• Refit the spark arrestor.

Air filter service:

• The engine will not run properly and may be damaged if using a dirty air filter. Replace the air filter once a year. Clean or replace more often if operating under dusty conditions.
• Undo air filter cover screw and remove air filter cover.
• Remove sponge filter element.
• Wash filter element in soapy water. Squeeze filter dry in clean cloth (DO NOT TWIST).
• Clean air filter cover before re-installing it.
• Put a drop of engine oil onto sponge filter element this will help avoid ice blocking it during winter season.

Valve clearances:

IMPORTANT: If you are not competent to carry out this procedure or the proper tools are not available. We advise that you take the generator to your dealer to have the valve clearance adjusted. This is a very important step to ensure longest life for the engine.

• After the first 50 hours of operation, check the valve clearance in the engine and adjust if necessary.

General:

• The generator should be started at least once every seven days and be allowed to run for at least 30 minutes. If this cannot be done and the unit must be stored for more than 30 days, use the following information as a guide to prepare it for storage. 

WARNING:

NEVER store engine with fuel in tank indoors or in enclosed, poorly ventilated areas where fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or other gas appliance.

WARNING:

Drain the fuel into an approved container outdoors, away from open flame. Make sure that the engine is cool. DO NOT smoke in the vicinity. NEVER cover the generator while the engine and exhaust areas are HOT. 

• DO NOT store petrol from one season to another.
• Replace the petrol container if it starts to rust. Rust and/or dirt in the petrol will cause problems with the carburetor and fuel system.
• If possible, store the unit indoors and cover it to give it protection from dust and dirt.
• Make sure that you empty the fuel tank.
• If it is not practical to empty the fuel tank and the unit is to be stored for some time, use a commercially available fuel stabilizer added to the petrol to increase the life of the petrol.
• Cover the unit with a suitable protective cover that does not retain moisture.

STORAGE & TRANSPORTATION:

Storage:

• It is important to avoid gum deposits from forming in essential fuel system parts such as the carburetor, fuel hose or tank during storage. Also, experience indicates that alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids storage. Acidic gas can damage the fuel system of an engine while in storage.
• To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer, empty fuel system as follows;
• Remove all petrol from the fuel tank.
• Start and run engine until engine stops from lack of fuel.
• While engine is still warm, drain oil from crankcase. Refill with recommended grade engine oil - SAE15W40.
• Remove the spark plug HT lead and spark plug and pour about 1/2 ounce (15 ml) of engine oil into the cylinder. Cover the spark plug hole with rag. Pull the recoil starter a couple times to lubricate the piston rings and cylinder bore.
• Install and tighten the spark plug. Do not re-connect spark plug HT lead.
• Clean the generator outer surfaces.
• Check that cooling air slots and openings on generator are clear of any obstructions.
• Store the unit in a clean dry, dust and dirt free place which is clear of any flammable and combustible materials.

Transportation:

• To avoid burn injuries you MUST allow the machine to cool fully when moving from one location to another. DO NOT move machine whilst it is still hot.
• You MUST drain the fuel tank before moving in a vehicle. Turn the fuel tap to the OFF position.
• To avoid injury or damage to the machine you MUST secure it whilst it is being transported in a vehicle.
• DO NOT use in an enclosed area or a moving vehicle.
