What Is Poured Into The Gear Of The Lawn Mower

The correct first start-up and running-in of the lawn mowers are very important steps in the start of operation of a new tool. On the one hand, they make it possible to preserve the motor resource of the gasoline engine laid down by the manufacturer, since at this stage grinding of moving units and parts takes place. On the other hand, the first necessary skills for working with a trimmer are acquired, if we are talking about the first tool in my life.

What Is Poured Into The Gear Of The Lawn Mower

  • Preparing for the first launch of the lawn mowers
  • Inspection and lubrication of the lawn mowing gear
  • Preparing the right fuel mixture
  • First Trimmer Trigger
  • Getting Started Running Lawn Mowers

Preparing for the first launch of the lawn mowers

Before you make the first start of the lawn mowing, you need to perform a series of sequential actions:

  • Inspect the gearbox and grease it;
  • Prepare the correct fuel mixture.

Inspection and lubrication of the lawn mowing gear

Checking the gearbox before starting the gas trimmer must be done on a regular basis. The absence of lubricant or its small amount increases the friction of the gear transmission of the gearbox operating at rather high speeds. As a result, overheating and gears occur. The lawnmow reducer fails. Prevent the occurrence of such damage during operation and helps regular inspection.

If, before starting the gas spit, an insufficient amount of grease in the gearbox or its absence is detected, “LITOL” is put into the housing. To do this, it is necessary to unscrew the screw on the bend of the gear housing and syringe “LITOL” in the amount of 1-2 ml.

Preparing the right fuel mixture

Before you start running in a new lawn mowing engine, you must also properly prepare the fuel mixture. As you know for two-stroke engines, it is prepared from special two-stroke oil and gasoline, taken in certain proportions. You can find out the proportions from the instructions that came with the tool or on the lubricant label. From the instructions you will also find out the recommended type of fuel, as well as the recommended type of engine oil.

Going to run in a new lawn mowers, many are faced with the problem of preparing the fuel mixture. And the reason for this disagreement in the instructions of the manufacturer of the tool and in the instructions of the manufacturer of motor oils. The former recommend a proportion of 1:25. The second recommend 1:50. Who to believe? How to proceed?

According to experts, if in the instructions for the lawn mowers the manufacturers write the proportion 1:25 or 1:30, then most likely this is either a cheap tool with poor cooling, or the manufacturer does not know which oil the consumer will add. But here it must be understood that an excess of lubricant does not affect the performance of the trimmer in the best way. Excess oil does not completely fade during engine operation. It cokes, clogs the cylinder and piston.

What to do in this situation when running a new tool? An ideal option would be to buy exactly the oil recommended by the manufacturer of the lawn mowers. In the case of run-in motors, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two-stroke oil for the gasoline tool of the same name. It is not cheap, but it lasts for a long time. It must be disturbed as described in the instructions on the bank.

First Trimmer Trigger

When everything is checked and the prepared fuel mixture is poured into the tank, the time comes for the first start of the trimmer before it is run-in. To do this, perform the following manipulations:

  1. Place the lawn mow on a flat horizontal surface;
  2. Move the choke control lever to the closed position;
  3. We pump up a few strokes of the primer fuel into the carburetor;
  4. Turn on the ignition toggle switch;
  5. Gently pull the starter cord until you feel resistance;
  6. After that, make a cord 3 4 sharp jerks until the lawn mowing starts;
  7. After starting, open the air damper.

Getting Started Running Lawn Mowers

After starting, do not rush to run the trimmer immediately. Allow the engine to idle for about 5 minutes. While warming up, adjust the choke lever with the choke lever so that the spool with fishing line or knife does not rotate. As soon as the tool warms up, we completely open the air supply by transferring the corresponding lever to the “ON” position and squeeze the gas trigger by 1/2 and hold for 20 30 seconds. Then we dump the gas, let the trimmer work for XX for 30.40 seconds. In this mode, we continue for 10 15 minutes. Then we muffle and let rest 15 20 minutes.

Having cooled the lawn mowing, we continue to run the engine according to the previous scheme. Start on a hot, trimmer must already have an open air damper. Try not to hold gas for a long time, as the moving parts of the tool only rub against each other. And do not let the engine idle for a long time as it can overheat.

The next stage is the running-in of the gasoline braid gearbox. To do this, select a site with soft young grass. We mow 5 10 minutes with pre-gas for 1/2 2/3 of the full throttle. After we take a break for 20 25 minutes. The cycle is repeated 3 4 times.

In general, running the lawn mowers according to the described algorithm is performed until the fuel mixture is fully developed in the tank. After which the tool is ready for continuous operation. In the process, monitor the temperature conditions of the gearbox and motor. They should not overheat.

  1. Lower and upper gear lubrication
  2. Grease for gas trimmer
  3. Prevention and possible malfunctions of the gearbox

A responsible approach to maintenance is the key to a long tool life. One of the requirements of the lawn mowing operation is timely lubrication of the gearbox, as well as filter cleaning. What composition to lubricate the gearbox, every user of such a unit knows. First cleaned in several stages, then remove the element from the casing. It is cleaned with gasoline, dried. A place for the filter is prepared carefully, cleaning it from dust and old oil. The main signal for lubricating the lawn mowing gear is extraneous noise and fast heating of the equipment. This suggests that it is necessary to lubricate the spare part as quickly as possible. The lubrication intervals are indicated in the lawn mowing instructions. Experts say that gearboxes need to be serviced every 15 hours.

Lower and upper gear lubrication

There are tips that recommend lubrication at the end of the season. However, most people find it best to do this at the beginning of each season. When we repair the unit, as well as carry out any disassembly, it is necessary to use lubricants. The gearbox must be additionally lubricated when the old trimmer is inserted.

Modern trimmers are equipped with a gearbox that measures the angle of transmission of mechanical energy between two components: a shaft and a head. Bevel gears are considered common, they easily withstand high speed, are equipped with smooth gearing, as well as an increased level of bearing capacity. The body includes a shaft, a gear wheel, which is pressed onto the driven shaft. In order to reduce friction, bearings are mounted on the shaft support points.

Grease for gas trimmer

Properly selected lawn care gives a guarantee of durability and high-quality equipment. Manufacturers try to take into account all the nuances and prescribe what materials to use for maintenance. Usually, the specific type of lubricant is not indicated, just well-known standards are given that lubricants must meet.

The lubricant must be selected in such a way as to take into account the temperature regime, rotation speed, load dynamics and vibration. The main requirement is that this mixture remains in the zone of maximum friction.

Based on the above information, it should be noted that lawn mowers manufacturers are developing universal additional tools for their equipment. It can be served by general industrial compounds. The main condition is compliance with the operating conditions, namely, the presence of a substance against rust and lime, as well as a filler, which consists of a solid lubricant. Grease is poured into the gearbox in a special hole, the assembly is not dismantled.

Replacement is quick enough.

  1. First, turn off the device from the network. Petrol devices must be drained from gasoline.
  2. If the lubricant changes completely, then be sure to flush the gearbox. To do this, first fill in the cleaner, then rinse the gearbox well, then drain. It is important to clean the case completely.
  3. The special tool that comes with the trimmer must unscrew the gearbox plug.
  4. We apply a new lubricant: we insert a syringe with a tube into the hole and squeeze out the lubricant (2-5 ml).
  5. Manually rotate the shaft, turn on the braid at low speed without load. This is necessary so that the lubricant is qualitatively distributed in places subject to maximum friction.

Prevention and possible malfunctions of the gearbox

Lawn mowing requires the first preventive maintenance immediately after the acquisition, because the manufacturer puts a small amount of grease. If the trimmer performs a small amount of work, then grease the device at the beginning and at the end of the season. If the lawn mower works a lot, then lubricate after 30-55 hours of operation.

The main malfunctions include the most common options.

  • Strong heat. This indicates that the grease has run out. It is necessary to add lubricants and run them in a weak mode.
  • The gearbox vibrates or staggers. This situation indicates mechanical damage.
  • There is a knock. Then the bearing collapsed, the boot is damaged.
  • If the trimmer knife is stuck, then the mechanism should be changed completely.
