x Do not smoke when using the line trimmer and ensure caution
when handling fuel. We recommend you fuel the machine at least
3m away from where you wish to work in case any spilt fuel ignites
when starting the engine.
x Ensure that bystanders, children and pets keep well away when
starting or trimming - at least 15m.
x Inspect the line trimmer, and in particular the trimming head, before
use for any worn or damaged parts. Do not use until the parts are
repaired or replaced.
x Before starting the engine make sure the trimming head is not
in contact with anything and have a clear work area and secure
footing.
x The line trimmer should not be stored in direct sunlight, or
exposed to high temperatures or damp and wet conditions.
 Clean the trimmer after each use and, if storing for a prolonged
period, drain down the fuel in the tank. Remove the spark plug
and put a few drops of oil into the cylinder before pulling the
starter a couple of times to distribute the oil evenly. Replace the
spark plug.

trimmer is not going to be used for a long period, drain the mixture
from the fuel tank, start the engine and drain the carburettor of
any remaining fuel.
 Dispose of any unwanted 2-stroke mixture at an authorised recy-
cling point.
