• ● Add and Change lubricating oil

All oil and fuel drained at factory prior to shipping. Before starting the engine, must follow the below instructions to proceed.

• ▲ Place engine on a balanced surface when adding the oil and doing inspection.

• ▲ To check the oil level, insert the oil gauge without tighten stick to get correct engine oil measurement level.

• ▲ Add the oil up to the marked level shows on oil gauge for correct operation.

• ▲ Before starting, oil gauge must be tighten.

• ● Recommended engine oil: API grade, or equivalent to or higher than SE grade

• Recommended lubricating oil type:

• Use 10W-30 or 10W-40 in the summer or winter condition

• Use 5W-20 in the very cool area

Based actual temperature condition, please use the correct lubricating engine oil for best performance of the engine.

●Precautions

▲ Oil level check (loosen oil gauge for correct oil level)

▲ Drain oil (Follow the manual to change oil) ▲ Change the engine oil when the engine is warm    To add new oil Caution of burning

▲ Always top of the engine oil

Model Level of oil GT241 0.4L GT400 0.6L GT600 0.6L GT1000 1.0L GT1300 1.0L

• ●Before starting

• ▲ Check the level of oil and gasoline.
• ▲ Check the air filter condition is clean or clogged.
• ▲ After shut down, gently pull the recoil starter two to three times to return to neutral position for easy start on next use.
• ▲ When starting, ensure all the switchers are on, choke is off, slight opening on the throttle

• ●Precaution in using

• ▲Inclination is allowed with 20 degree (PTO, Carburetor, Air filter and etc)

• → Avoid the fuel leakage from the tank
• → Avoid uneven surface to effect standard operating RPM.
• → Avoid carburetor leakage from the oil pipe
• → Avoid touching the oil alert and cause the shutdown of the engine.
• ▲ Oil Alert
• → When the oil reach below allowed level, it will cause shutdown of the engine.
• → For engine equipment with oil alert light, light will blink when the oil reach below allowed level, and cause shutdown of the engine at the same time.
• → Circuit diagram:

Addition to scheduled maintenance, periodically check up is also needed to keep the engine performance and duration. If you need more information, please refer to your manual.

	No kindling Daily checking ● Semi-soak type If element is heavily clogged or over dry, wash the element with kerosene, air dry the filter, soak in engine oil and squeezing well before install.
	Oil bath type: If the oil level is low, it is added to the normal oil surface. If dirty, cleaning oil and components, components will be immersed in oil, fling off excess oil or squeeze gently after installation.
	Paper type: Foam element: If element is heavily clogged or over dry, wash the element with kerosene, air dry the filter, soak in engine oil and squeezing well before install. Paper element: If element is clogged with dust, tap lightly or blow air to remove the dust. If the element is excessively clogged, please replace it.

	● Cleaning of spark plug Every 50 hours of operation remove carbon build up on the electrode, clean with sandpaper if necessary. Be careful not to touch the end of center electrode all time.
	● Adjustment of electrode gap Standard value 0.6～0.7mm The electrode burning situation differs according to operation condition (load condition), so when abnormal blackening or excessive burning happen, must replace with hot-type of cold-type spark plug base on the situation.
	● Spark check Inspect and adjust the spark plug after confirming the stopping switch is at “ON” position. Precaution • Be careful not to contact the high tension cable while pulling the recoiler. • Ensure no gasoline is around the spark plug (Or will cause fire) •Do not ground near spark plug hole (Fire danger may occur on all type of gas/fuel with gasoline mixture ).

	● Cleaning carbon buildup on cylinder head Every 100 hours of operation
	● Cleaning carbon buildup on piston surface Remove cylinder head, clean around the valve and piston surface

● Remove all kind of buildup such as soil, leaves, oil sludge from the heat sink plate to restore standard performance

▼Cylinder box radiator	▼Cylinder head heat sink	▼Start the tuyere

● Every 50 hours usage take out the strainer cup and remove deposit as well as dust on filer net of strainer cup.

●Drain fuel in the fuel tank and the carburetor. (Loosen the screw of the carburetor and drain the fuel) ●Remove the spark plug, add a small amout (about 2-3 cc) of engine oil into the cylinder, pull the recoil rope slowly for several times, reinstall the spark plug and release recoil rope when feel having pressure. (neutral point of decompression) ●Clean the surface with oil soaked cloth, store in cool and dry place.

It’s the best to use systemize to identify the correct source/reason of engine failure. We listed the general problems and possible cause at below. First of all, find out the problem of the engine. Then, identify the possible cause. Before starting the engine, please follow the safety precaution notice.
