Signs of a fake

1. Label . Manufacturers of counterfeits forget to indicate all the necessary data on the label. Before purchasing car oil, find out what the original label looks like.
2. Color . Typically, counterfeit petroleum products are much darker than the real thing.
3. Structure . The original lubricant does not leave sediment and does not contain various foreign particles.
4. Price . It is suspicious if car oil from a well-known manufacturer costs mere pennies. If the price of a petroleum product is too low, know that it is most likely a fake.
5. Paper test . High-quality oil does not leave a visible trace, flowing down a simple piece of paper. A fake leaves a dark trail behind itself.

Attachments

To significantly expand the capabilities of the walk-behind tractor, various attachments are installed. The most widely used are:

• Plows.
• Seeders.
• Dumps.
• Mowers.

When choosing, you need to pay attention to what kind of towbar is required. In some cases, thrust from the engine is transmitted to attachments through an intermediate element.

How much to fill

Most walk-behind tractors presented on the Russian market are equipped with engines from the HondaGX family, their Chinese clones, or Subaru-Robin engines of a similar design.

For a one-time full filling of such an engine with oil, no more than 0.6 liters of oil will be required - which is why this packaging volume is popular among manufacturers. More powerful modifications of these engines can hold a liter or more of oil.

A number of engines, the design of which includes an additional reduction gearbox, have a separate space for its lubrication.

Operating and maintenance instructions

With proper operation and maintenance of the equipment, it can operate for a long period. The operating instructions are as follows:

• Equipment is assembled and installed, all elements are connected.
• Engines are supplied dry. This moment determines that you need to purchase a suitable lubricant and pour it into the structure. Some models work with a fuel mixture that includes oil.
• The first start must be done carefully. To do this, select idle mode, the engine warms up for several minutes.
• After working for the first 20 minutes, it is recommended to drain the old oil, after which new oil is added. This is due to the fact that at the time of grinding in the main elements, metal shavings may get into the lubricant.
• For the first few hours, it is recommended to use the cultivator at 2/3 power. This will eliminate the possibility of various malfunctions.
• At first, it is recommended to monitor the engine temperature, because... there is a possibility of it overheating.
• If the engine is unstable, you need to stop the walk-behind tractor and then find the cause of the problem.
• After operating the equipment, the surface should be cleaned of various contaminants. In addition, the condition of all main elements is checked, because further operation with malfunctions is not allowed.

Maintenance includes timely oil changes. In this case, you need to periodically add lubricant to the gearbox.

How to check the ignition coil in a small engine

Hazard warnings

: When attempting to start the engine or equipment, avoid any rotating, moving parts or other hazardous areas.

The coil is probably the easiest to test, so it's the first thing to check when troubleshooting your ignition system.

Checking the coil or armature

• Step 1
  : Attach one end of the spark plug indicator (P/N 19368) to the ignition cable and the other end to the cylinder head as shown below.

If a spark appears in the indicator gap, the ignition coil is working normally. If not, it needs to be replaced.

Does the engine stop while running? Install the indicator between the ignition cable and the spark plug and start the engine. When he stops, watch the window.

Common mistakes when checking coils

• Be sure to disconnect the coil from the equipment wiring harness as well as the engine wiring harness and use the spark plug indicator. Many technicians mistakenly replace a service coil because the coil's ground wire is shorted to a piece of sheet metal.
• DO NOT connect an indicator to the spark plug to check this. This may start the engine. You won't be able to turn it off without a ground wire installed.
