Trimming operation
Line pushed into wire fencing will snap off.
Avoid wire
Basic trimming operation with metal blade
Please observe the following instructions when trimming.
Ensure that the trimmer blade does not come into contact with hard obstructions such as stone, metal, or concrete.
If the blade hits an obstruction, turn off the engine immediately and ensure that the blade has
stopped before checking the blade and shield for damage.
Never use cracked blades, as they could fly off while you are working.
Check to ensure that the trimmer blade has been tightened securely in place.
Replace the shield if it is damaged or cracked.
Replace the trimmer blade nut when it becomes worn.
Failure to do so could lead to an accident or serious injury.
Engine operating speeds
Use correct blade
Inspect blades before use
Do not push the line into tough weeds, trees, or wire fences.
Pushing the line into chicken wire, chain link fencing or thick
brush can result in snapped-off line ends being hurled back at the
operator. The proper way is to cut right up to a barrier, such as
any of those mentioned, but never run the line into or through the
obstruction. Do not cut closely to obstruction or barrier.
Avoid nylon line contact with broken wire fencing. Pieces of wire
broken off by the trimmer can be hurled at high speeds.
WARNING
Operate the engine at full throttle while cutting. Best fuel efficien-
cy is obtained by releasing the throttle when swinging back after
a cut.
To prevent possible engine damage, do not allow the trimmer
or brushcutter to run at high speeds without a load.
Avoid operating the attachment at low speeds. Doing so can
lead to rapid clutch wear. In addition, slow-speed operation
tends to cause grass and debris to wrap around the cutting at-
tachment.
Always use the blade suited for the job.
Do not allow the trimmer blade to come into contact with hard
obstructions such as stone, concrete or metal.
Do not cut into the ground with the blade.
If the blade hits an obstruction, turn the engine off immediately
and ensure that the trimmer blade has stopped rotating before
checking the blade and shield for damage.
Do not operate with a dull, bent, fractured or discoloured blade
and worn or damaged nut.
Never use a cracked trimmer blade as it could shatter off while
you are working.
Do not run engine at full throttle without a load.
Remove all foreign objects from work area.
