Swath length could be longer than necessary Decrease the length of the swath to the recommended mark and ensure that it is not longer than necessary.

Starting, stopping and adjusting throttle
The unit’s throttle lock can be used for preventing the accidental operation or manipulation of the main throttle control setting. By engaging the main lock switch A, you will enable the release of the throttle control handle and this allows you to switch the main throttle speed and change its position. After you have set the desired position, you can set the handle (B) back to the locked position by pulling back the lock switch to effectively freeze the throttle setting.

Similarly, you can utilize the stop switch to turn the engine completely off – to start the engine, set the appropriate throttle setting and then pull the throttle handle sharply. Ensure that you release the handle gradually after you have brought the unit to a start. Aim to always start the weed eater from an almost horizontal position in order to enable quicker starting. Before you start the unit, ensure that the primary supporting flange has not been compromised due to repeated use. Also make sure that the machine is on the ground in a clear patch, away from obstacles such as stones, twigs and other artifacts. If you’re having difficulty starting the unit, use the air purge to keep pumping the unit with fresh air in order to optimize air fuel mixture. Practice extreme caution when starting in order to prevent any injury, ensure that no part of your body is near the spinning line.

Operational guide and trimming techniques
Hold the unit with both hands with a firm grip and begin to trim by gradually working your way across the lawn area in slow deliberate steps. Do not move too fast in order to get a well-defined and efficient cutting experience. Ensure that you hold the main unit below the waist height level. It’s crucial that you do not allow the trimmer unit’s head to touch the ground as this can hamper the main motor and degrade its performance. It’s also extremely hazardous to try to remove any cut material from the machine when the unit is powered on. Allow the engine to always slow down to a basic idle speed after each trimming session.

Ensure that you hold the trimmer head at an angle while using the unit to cut through the lawn. Ensure that the angle is not too steep as this can hinder optimal performance of the weed eater and compromise your gardening efficiency. Pressing the cord into the garden lawn can not only degrade performance and slow down the motor, it can severely damage the unit and require expensive repairs to rectify. Grass, weeds and other vegetation can easily be sliced off by the weed eater without much effort however blunt objects and stumps can damage the line – hence, a prior inspection is important.

However, the nylon line is significantly strong enough to cause considerable damage to property and even sensitive tree barks or even fencing – hence be careful and mindful of your surroundings when operating the unit. It’s recommended that you maintain a cord length of anywhere between 10-12 cm in order to get the most from your trimmer. You can also employ the clearing technique in order to get a good well-rounded cut in places with a higher density of unwanted vegetation, such as closer to the barks of trees. While holding the trimming head well above the ground and gradually tilt it until the cord begins to slash at the ground just beneath and around the bark, where the vegetation is thicker.

The most popular employed method is the regular cutting streak, where the trimming head is held parallel to the ground with the string trimming equal vegetation on both sides. This method is ideal for cutting lawns that cannot be easily trimmed with a conventional mower.
Remember however, that constantly allowing the cord to come in contact with the ground can result in increased wear and tear to the unit.
