What Oil Is Pouring Champion Lawn Mower Engine

What you need to know about the running-in and operation of four-stroke air-cooled gasoline engines installed on garden, construction and road motorcycle equipment.

Gasoline four-stroke air-cooled engines are widely used in landscape gardening equipment. Tilleries, motor cultivators, lawn mowers, snow blowers, motor pumps, mini tractors, on construction and road-building equipment. Gas generators, vibrating plates, rammers.

Before starting engine operation LEARN INSTRUCTIONS FOR USE. Many buyers, unfortunately, do not. Therefore, the most basic questions on the use of the motor arise.

Tip: READ ENGINE OPERATION MANUAL.

First: which gasoline to use.

We recommend the use of clean, fresh, unleaded gasoline with an octane rating of AI92. Air-cooled engines are not designed for use with AI95 and AI98 fuels. The 95th and 98th gasoline contains additives that have a detrimental effect on the piston system of the engine, leading to overheating and breakdown.

Do not mix oil with gasoline. This may result in engine malfunctions that are not covered by the warranty.

Use FRESH AI-92 GASOLINE WITH A PERIOD OF STORAGE FOR NO MORE THAN 30 DAYS.

Secondly: what kind of oil is poured into the crankcase.

Many people consider automobile oil of well-known brands to be the best for use in tiller engines (motor cultivator, snowmobile, electric generator, motor pump, etc.). This is completely wrong. Automotive oils are designed to work in water-cooled engines, not air. The boiling point of automobile oils is lower than that of oils that contain special additives for air-cooled engines.

Use oil with a quality class of SF, SG, SH, SJ, CD or higher. Do not apply oil additives. Select oil viscosity based on ambient temperature.

Sae 30 (5 ° C and above) is recommended for temperatures above 5 ° C. When used below 5 ° C, it can cause a difficult start.

10w-30 (-18 to 38 ° C) is recommended for variable temperatures. This oil provides a cold start to the engine, but can lead to increased oil consumption at temperatures above 27 ° C.

Check the oil level more often at elevated air temperatures.

Synthetic 5W-30 (-30 to 40 ° C). Synthetic oil provides engine operation over the entire temperature range, as well as easy starting and reduced oil consumption.

5w-30 (5 ° C and below) is recommended for use in winter conditions.

Fill OILS ONLY SPECIFIED IN THE ENGINE INSTRUCTIONS.

Always check the oil level. The level should be at the last thread of the filler neck in the horizontal position of the engine (as shown in the figure). Fill and drain holes are located on the front and rear of the engine.

Engine Oil Fill Level

On lawn mowers, pay attention to the dipstick. On the engine probe with a vertical shaft, marks are indicated.

Different engines have different crankcase volumes. If you have an engine of 4, 5.5, 6.5 or 7 hp then pour 600 ml. Oils. In engines of 7.5 hp poured 900 ml. In engines with a capacity of 8, 9, 11, 13 and 15 hp respectively 1.1 liters.

Third: starting the engine.

At the first or cold start of the engine, an increased load on the piston system occurs. High revs can damage the motor. Therefore, it is necessary to start the engine at 1/3 of the gas position. And you need to run in at medium speeds.

Fourth: how the engine breaks in.

Air cooled engines “do not like” idle move. Start the engine, warm up for 1-2 minutes. And run in work. During break-in, try to adhere to 50-75% of the load and take mandatory breaks in work after 20-25 minutes. After a break, when the engine has cooled down (15-20 minutes), you can continue to work again. In this mode, the engine should run for the first 4-5 hours, after which the oil must be replaced. Break-in is over.

The main causes of engine failures

Remember. Engine failures occur mainly from improper operation.

The first reason for the breakdown is an unopened fuel cock.

When the engine is not running and the fuel valve is open, carburetor overfill and “flooding” candles. Also gasoline enters the crankcase. And this will lead to excessive pressure during engine operation and squeezing out the seals. Then this mixture of gasoline and oil will enter the combustion chamber and through the exhaust valve into the muffler. Gradually, the muffler will become clogged with oil residues and the engine will lose traction.

Close THE FUEL CRANE AFTER WORK MANDATORY.

The second reason for failure: during transportation or storage, the engine was turned over.

Since the engine is 4-stroke. Gasoline is poured into the tank, oil in the crankcase. And they should not mix. After a coup, these components are usually mixed in a carburetor. After that, the engine will need to be disassembled and cleaned.

Do NOT OVERLOAD THE FUELED ENGINE.

And the third reason for the failure: improper starting of the motor with a manual starter.

Many users of four-stroke engines think that the more you pull the starter handle, the better the engine will start. This is not true. The starter handle must be pulled until the cams engage, and then gently, but with a large amplitude, pull up. And the engine (if it is working of course) will certainly start.
