How to Install a Fishing Line on a Huter Trimmer Coil
At first glance, a simple device for mowing grass using a two-stroke engine, has a fine tuning. Lawn mowing repair must be entrusted to a specialist or to study the technique yourself, using the instruction manual. Maintenance of the spit is necessary. Gearbox lubrication, fishing line replacement, tooth grinding can be carried out on their own.
Faults of lawn mowers and methods for their elimination
Any type of lawn mower has a hollow rod, in which a connecting cable is placed between the motor shaft and the lower gear, which transfers rotation to the working body with a cutting tool. In the upper part there is a carburetor and a motor, at the bottom. A gearbox and a working tool, closed by a casing. In the middle part there is a transverse handle in which the control buttons are located. For unloading hands, there is an unloading belt holding the bar with the torso of the operator.
When choosing lawn mowers, a device with a two-stroke engine is preferable to a four-stroke one. The two-stroke motor is more maneuverable and easier to repair. With a four-stroke assembly, lower vibration levels.
They follow this, lawn mowing repair consists in troubleshooting;
- The engine does not start;
- The cutting mechanism is not gaining momentum;
- Engine stalls;
- Gearbox warms up;
- An extraneous knock is heard, strong boom vibration.
Before fixing the malfunction, it is necessary to carry out diagnostics, to determine a non-working unit.
It is important to know the lubrication points of the tool. Constant care, cleaning the device after work will extend its life. Before work, it is necessary to tighten the mounting bolts, prepare fuel and refuel the tank.
Chainsaw Engine Does Not Start
If the mechanism does not start, it immediately dies, and consistently check:
- Is there fuel in the tank?
- Good condition of the spark plug;
- Clean air and fuel filters;
- Clean breather and exhaust channel.
It is necessary to refuel with a freshly prepared mixture based on AI-92, the oil is injected for accurate dosage with a medical syringe. This will help avoid expensive chainsaw repairs.
It is necessary to make sure that the candle is working, it gives a spark in contact with the body. In this case, it is necessary to dry the candle channel, clean and dry the part itself. You can change the candle, but the channel still needs to be dried for 40 minutes. Check the serviceability of the high-voltage wire; there may not always be a contact. Malfunction in the ignition unit when repairing lawn mowers, do not fix it yourself.
If the engine filter does not stall when the air filter is removed, the reason is that it requires replacement or cleaning. Replace the filter on the fuel with great care. After checking the cleanliness of the breather, remove the silencer mesh and clean the exhaust channel.
The next step is to repair the carburetor, where you have to find the fault and fix it, taking into account the tiny dimensions of the parts. If the simplest operations did not bring results, in order not to violate the fine-tuning of the system, it is better to entrust the repair to a specialist. How to start the diagnosis and how to properly repair the lawn mowings with your own hands, check out the:
Repair and lubrication of the lawn mowing gear
The role of the gearbox is to transmit torque from the motor shaft to the cutting tool through 2 gears with different numbers of teeth. The torque is transmitted at an angle of 30 0. The number of revolutions of the lower cutting disc is 1.4 times less than the engine speed. Gears must be clean and lubricated. To supply oil to the teeth, there is a hole under the screw on top.
The lawn mowing gearbox is lubricated at least once per season. If the work is intense or there is an extraneous noise in the lower node, lubricate more often.
First, clean the ground and grass where the plug closes the hole. Unscrew the cork with the appropriate tool, it is supplied with the saw. We use tube grease. Either native lubricant from the manufacturer or well-known high-quality compounds such as Oleo-Mas, Litol. 24, Azmol 158. Are selected. We open the protective layer of the tube and lay the tool on its side. Slowly rotating the knife, squeeze out the grease into the gear case. Gears, turning, spread the composition with teeth over the entire surface. You can also pour grease with a special syringe.
Lack of or a large amount of grease can cause the gearbox to heat up. An audible knock and play indicates the destruction of the bearing or the ingress of dirt due to damage to the anthers. Bearings must be replaced using a puller, without using the heating method.
If the gearbox staggers and moves along the boom, it is necessary to replace the housing, or temporarily tighten the assembly with a clamp to fix it to the pipe. If the knife does not rotate, then the gears do not mesh. The teeth are worn or crumbled. You will need to replace the pair with a full analysis of the node.
Dismantling the gearbox with the dismantling of the shaft and bearing units cannot be carried out by heating. When heated, the metal loses its strength properties and subsequently the assembly becomes unreliable. To remove the bearings use a puller.
When replacing the gearbox, it is necessary to choose a new unit, being guided by:
- Pipe diameter;
- Drive shaft diameter;
- Section of the drive shaft;
- Ways to attach protection
The saw headset dulls or wears out over time. Work with the tool becomes tense, the load increases, the quality of the swath is deteriorating. Metal saw blades sharpen, plastic change.
If the fishing line serves as the cutting tool, it gradually wears out, and new material is installed in the coil. The principle of operation of the cutter with fishing line is the gradual unwinding of the coil under the action of centrifugal force. Upon contact with the grass, the fishing line is abraded and fed gradually from the reel. A special winding is needed so that the two cutting elements come out simultaneously and do not get confused with each other.
The figure shows how to properly wind the line onto the lawn mowing coil. Before you rewind a new fishing line you need:
- Having unscrewed the nozzle, carefully remove the cover, holding the spring by hand;
- Remove scraps of old fishing line from the coil;
- Measure 5 meters of a new string and fold it in half;
- In the coil, guides for 2 ends, hook the middle part into the recess and wind in the direction of the arrows for each half of the string;
- Spend the remaining 20 cm through special recesses at opposite ends of the coil;
- Install the spring and washers, bring the ends of the fishing line out, close the drum with a lid.
