FUEL FOR 2-STROKE ENGINES
When starting the engine for the first time, a mixture of gasoline and oil for a 2-stroke engine is used in a ratio of 1/25 (per 1 liter of gasoline 40 ml of oil) after a run-in, a mixture of 1/40 (per 1 liter of gasoline 25 ml of oil) is used!
Use unleaded gasoline with an octane rating of 92.
Use the special two-stroke engine oil recommended by the manufacturer.
Do not use oil designed for four-stroke engines.
A different fuel mixture may cause engine damage. Make sure the ratio is correct.
It is important to use only high quality fresh gasoline and oil. The mixture should be used within three weeks from the date of preparation.
Gasoline and oil must be mixed until the tank is full. To prepare a gasoline mixture, use a special measuring container. This operation can be performed in a well-ventilated area away from open flame, sparks or lighting when the engine is off. Never smoke or use your mobile phone during this operation. Shake the mixture well in the gas tank before use.
In order to fill the gas tank, unscrew the tank cap and, using a funnel, fill the gasoline-oil mixture into the tank. If you spill the mixture, immediately wipe it off. If you spilled fuel, to avoid the risk of fire, start the engine at least three meters from the place where the tank was filled.
Never fill the tank while the engine is hot.
To start the engine:
- Press the accelerator lever and the red button on the right handle for the “START” position on models with a ‘U’-shaped handle.
- Pour gas into the carburetor by slowly pressing the swap button several times until gas enters the carburetor.
- Move the carburetor choke lever to the closed position.
- With your left hand, grasp the scythe and hold the transmission stem firmly on the ground. With your right hand, slowly pull on the unwinder handle until you feel traction with the flywheel.
- Pull the starter handle 4 or 5 times until the engine starts. The red button will return to its original position when the accelerator lever is engaged.
- After starting, release the choke lever to the open position:
- To avoid damage to the unwinder, never yank the cord all the way.
If the engine starts to choke, turn off the ignition, unscrew the candle, wipe it dry or replace it, pull the unwinder several times without a candle in its place and turn off the engine in the open position. This will help to clean and vent the combustion chamber.
Attention! When the engine is at operating temperature, these operations are not necessary. Pull the unwinder until the engine starts.
When the engine is idling, the cutting nozzle must not rotate. In the event that it rotates, contact the service center for repair work for help.
During the first ten hours of operation, maintain moderate engine operation. Do not run the engine at maximum speed for an extended period of time until all components are fixed. After the engine has been run-in, it can be started at full power.
After the first two hours of operation, check that all nuts and screws are tightened securely and tighten them if necessary. Use the saturated fuel mixture in a ratio of 1/25 to break in the engine of the lawn mowers. Enough 1 tank to break in the engine.
Terms of Use
The protective cover consists of two parts. The main fixed part and the plastic part holding the blade.
- When using a nylon nozzle (fishing line):
The protective cover must be used with both parts in place; (the main part is the plastic part holding the blade).
- During use of 3 blade disc.
Remove the plastic part holding the blade (using a screwdriver) and use only the main protective cover.
Use only the cutting tools supplied by the manufacturer. All other blades, especially CUTTING DISCS, DO NOT USE!
This scythe is intended only for mowing grass and small shrubs.
Make sure that the device is perfectly balanced between the engine and the cutting attachment. The cutting nozzle should be parallel to the ground and should not require effort to hold in a working position.
after starting the engine, slightly press the gas button a couple of times to make sure that the lawn mowing is assembled correctly and that all parts are firmly fixed.
Before starting work, check that the cutting head is well fixed. Always carry the device with the cutting attachment below the height of the waist and as far away from the body as possible. Make sure there are no people, animals or other objects within a radius of 15 meters
Mow grass in strips of 1.5 meters wide, maintaining the balance of the device. When using a 3-blade blade for mowing grass or shrubs, always mow from right to left in order to leave mowed grass on the left for harvesting.
Try to avoid stones, earthen mounds, wooden knots or anything hiding or poorly visible in the grass.
If, when mowing, you accidentally hit a large object with a three-blade disc or a fishing line gets tangled and the rotation speed becomes lower. Stop the engine, lay the scythe on the ground, and check that the cutting device has not been damaged (for example, the blades on the blade break or a crack appears on the body). Replace the cutting tip if necessary. If grass has wound around the nozzle, remove it by hand and clean the cutting nozzle.
Always wear protective gloves for such an operation when turning off the engine and rotating the nozzle.
When the two nylon cords become too short, add gas at engine speed and lower the nylon nozzle to the ground. Automatically two nylon cords are aligned to the desired length. Repeat the operation if necessary.
Proper use of a 3-blade blade
During operation of the braid, all protective systems and parts of the tool must be in good condition.
When using a 3-blade blade, avoid the risk of serious injury, observing all safety rules. Pay attention to the picture below.
When mowing hard fibrous materials, always use the 3-blade blade in the circular “A” direction below.
The circular direction “B” is applicable only if the braid is in a very strong grip. It is not recommended to use it.
The circular “NO” direction is prohibited because it can endanger people and animals. Never use this direction.
All protective equipment and protective equipment must be constantly maintained in good working condition.
The engine and cutting attachment must be completely shut off during assembly, repair and cleaning.
Set the ignition switch to the “STOP” position.
During use, the braids vibrate. Although equipped with an anti-vibration device, vibration can cause increased fatigue. To do this, it is recommended to make regular pauses during operation.
It is also recommended that after several hours of operation, the device is allowed to idle for several minutes in order for the engine to cool.
Carburetor
- Idle adjustment.
- Adjust the idle speed with the idle thumb screw until the engine starts to run at about 2500 rpm.
Annual maintenance
- Clean the air filter in warm, soapy water. Dry and lightly lubricate before assembly or replace if necessary.
- Remove and replace the fuel filter.
- Remove and check the spark plug.
- Replace if worn or if there is a large layer of soot.
After 25 hours of using the braid, lubricate the gearbox. Loosen the side screw of the gearbox and put the grease inside. Use special gear lubricant designed for high temperature operation. Screw the cover into place and tighten.
Maintenance and storage after use
Clean the scythe thoroughly after use. Remove all residual grass and dirt; Check to see if anything extra is wrapped around the cutting tip. If possible, return the device for safe storage or transport to its original packaging.
