Installing a blade
Do not attempt to fit the trimmer blade with one hand or without using the socket spanner. Fit the trimmer blade ac-
curately using the supplied socket spanner and tighten firmly in position.
The trimmer must not be used if the blade vibrates or is loose.
Wear heavy duty gloves when working with the trimmer blade. When replacing the trimmer blade during a trimming
task, ensure that the engine is switched off and that the blades have stopped.
Do not use any tools other than the proved socket spanner to tighten the blade, a pneumatic or electric tool may
tighten the blade more than necessary and cause the nut or the output shaft to break.
When turning the product over to replace the trimmer blade, ensure that the fuel tank cap is securely in place.
Failure to do so could lead to an injury or serious accident, or cause a fire.
