Additional Safety warnings
Warning! Keep toddlers away when you assemble the unit. Small parts can be easily swallowed. There is also a risk that the polybag can suffocate toddlers.
Warning! When wearing hearing protection, and due to the noise produced by the unit, the operator may not notice persons approaching.
If the unit starts unintentionally when the mains plug is connected, disconnect the mains at once. Contact FLYMO Service to check the unit.
Warning! This unit makes an electromagnetic field while it operates. This field may under some con ditions interfere with active or passive medical implants. To decrease the risk of conditions that can possibly injure or kill, we recommend persons with medical implants to speak with their physician and the medical implant manufacturer before operating. If your trimmer is damaged in any way contact your local approved service centre.
→ Never use a damaged trimmer.
Inspect the area to be cut before each use. Remove all objects such as stones, broken glass, nails, wire, string etc, which can be thrown or become entangled in the trimmer head.

Warning: The cutting line continues to rotate after the machine has been switched off.

Warning: Beware of finger entrapment while putting the upper and the lower shaft together [Fig. A1].
Unplug the device immediately in case it doesn't stop anymore.
Do not lean over the trimmer guard – objects may be thrown by the cutting line.
Don't use the trimmer for pond, river, stream, or creek care. Water in the product could cause a malfunction, or an electrical shock.
Do not operate the trimmer in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Trimmers create sparks which may ignite the dust or fumes.
If the unit starts unintentionally when the mains plug is connected, disconnect the mains at once. Contact FLYMO to check the unit.

→ Do not bypass the safety devices or switches. For example do not attach the start lever ⑱ to the handle.
To start:
The product is fitted with a two-handed safety device (start lever ⑱ with safety interlock ⑰) to prevent the product from being turned on by accident.

To extend the cutting filament (double auto feed system) [Fig. O10]:
A clean cut is achieved only with the maximum filament ^19 length.
The cutting filament ⑲ is lengthened automatically when the filament cassette comes to a standstill after switch off.
As the filament can only be lengthened in small increments, it can be necessary in some cases to repeat the switch-off / switch-on action several times (up to 6 times). Important is that the filament cassette comes to a complete standstill each time.
The cutting filament has been sufficiently lengthened when, after switch-on, it audibly strikes the filament limiter ^20 .
The filament cassette has to be replaced when the cutting filament has been used up:
