mm line must be used.

provided or cut two pieces of trimmer line 28 cm each.

of the line head.

of the line head, gently pull back slightly to ensure the

Installing the blade
WARNING
Be certain all knobs and fasteners are fully tightened
before operating the product. Periodically check
for tightness during use to avoid serious injury.
WARNING
Please note that the blade nut is a Nylon locking nut,
to be used for one time assembly only. After the Nylon
locking nut has been assembled once, it must not be
re-used. When installing/re-installing the blade onto the
gearbox assembly, use a new Nylon locking nut. Failure
to follow this procedure can result in serious injury.
To reduce the risk of injury, keep the blade protector on the
blade at all times. Remove the blade protector only during
cutting operations.
Ŷ Centre the blade on the upper flange washer and make
sure the blade sits flat. Install the cupped washer and
make sure it sits well into the gear shaft. Install the
blade washer with the raised centre away from the
blade.
Ŷ Install the blade nut.
Ŷ Place the Allen wrench through the hole in the upper
flange washer and the hole in the gear head. Using the
wrench, turn the blade nut at least 4 turns after finger
