Trimming operation
Kickback
Precautions to observe when working
Kickback.
If you hit a hard object with the front-right of the trimmer blade,
such as when trimming in both directions, the blade will kick
sharply back to the right. This is a phenomenon known as "kick
back", and can cause a serious accident due to the operator los-
ing control over the product. Take particular care to ensure that
you do not strike any hard object with the front-right of the trimmer
blade.
The area within a radius of 15m of the product is a danger
zone. Make sure that there are no children, onlookers, or pets
in this zone. If anyone comes within 15m, turn off the engine
immediately to stop the blade from rotating.
If someone is helping you with the work or you are working to-
gether, identify the way in which you will signal to each other
and work at least 15m apart. You are advised to carry a whistle
in case you need to communicate.
Turn off the engine immediately if the product suddenly starts
to vibrate abnormally. Sudden vibration may be caused by a
problem with a component such as the flywheel, clutch, or
trimmer blade, or by a loose screw or other such factor. Do not
use the product until you have identified the cause of the prob-
lem and the repair has been completed.
The trimmer blade could fly off unless tightened securely. En-
sure that it is fitted securely in place.
Replace the shield if it is damaged or cracked.
If you work with the angle transmission in contact with the sur-
face of the ground, the trimmer blade nut and cup can easily
become worn. Replace them with new parts if this happens.
When you turn off the engine, check to ensure that the trimmer
blade has stopped rotating before you lower the product to the
ground. Even if the engine has been turned off, the blade can
still cause an injury while free-wheeling.
The silencer will remain hot for some time after the engine has
been turned off. Carry the product with the silencer away from
you to avoid touching it with your body.
When carrying the product, always turn the engine off and fit
the trimmer blade cover over the trimmer blade.
