Servicing
•It is recommended once you first use your petrol line trimmer to get it serviced after 15 hours of use.
•From thereafter, service the petrol line trimmer every 2 years.
Storage and maintenance after use
•When you finish working, clean the petrol line trimmer completely, making sure there is no grass or dirt wrapped in the cutting tools, and put it back into its package in order to avoid its hurting you or other people during transport.
•Be aware to not hit or cut the fuel tank (7) while you put it onto the ground. Do not let the petrol line trimmer fall down to the floor or it may damage the machine.
•Store the petrol line trimmer away from direct sunlight.
•Do not store in a nylon bag as this can encourage the formation of mould.
•At the end of the season, give the petrol line trimmer an overall cleaning and a thorough check.
•Do not leave the petrol line trimmer resting on the floor for extended periods as it could cause the shape of the guard to alter, posing a safety risk. Hang it off the floor by the top handgrip.
Whenever the machine is not used for a long period of time, proceed as follows:
•Empty the fuel tank completely.
•Protect all metal engine parts from corrosion by coating them with oil.
•Remove the spark plug, put a few drops of oil into the cylinder and then pull the recoil starter 2 to 3 times in order to distribute the oil evenly. Replace the spark plug.
