CORDLESS HEDGE TRIMMER
SAFETY WARNINGS
1. Keep all parts of the body away from the
cutter blade. Do not remove cut material or
hold material to be cut when blades are
moving. Make sure the switch is off when
clearing jammed material. A moment of
inattention while operating the hedge trimmer
may result in serious personal injury.
2. Carry the hedge trimmer by the handle with
the cutter blade stopped. When transporting
or storing the hedge trimmer always fit the
cutting device cover. Proper handling of the
hedge trimmer will reduce possible personal
injury from the cutter blades.
3. Hold the power tool by insulated gripping
surfaces only, because the cutter blade may
contact hidden wiring. Cutter blades contacting
a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
4. Do not use the hedge trimmer in the rain or in wet
or very damp conditions. The electric motor is not
waterproof.
5. First-time users should have an experienced
hedge trimmer user show them how to use the
trimmer.
6. The hedge trimmer must not be used by children
or young persons under 18 years of age. Young
persons over 16 years of age may be exempted
from this restriction if they are undergoing training
under the supervision of an expert.

7. Use the hedge trimmer only if you are in good
physical condition. If you are tired, your attention
will be reduced. Be especially careful at the end
of a working day. Perform all work calmly and
carefully. The user is responsible for all damages
to third parties.
8. Never use the trimmer when under the influence
of alcohol, drugs or medication.
9. Work gloves of stout leather are part of the basic
equipment of the hedge trimmer and must always
be worn when working with it. Also wear sturdy
shoes with anti-skid soles.
10. Before starting work check to make sure that the
trimmer is in good and safe working order. Ensure
guards are fitted properly. The hedge trimmer
must not be used unless fully assembled.
11. Make sure you have a secure footing before
starting operation.
12. Hold the tool firmly when using the tool.
13. Do not operate the tool at no-load unnecessarily.
14. Immediately switch off the motor and remove the
battery cartridge if the cutter should come into
contact with a fence or other hard object. Check
the cutter for damage, and if damaged repair
immediately.
15. Before checking the cutter, taking care of faults,
or removing material caught in the cutter, always
switch off the trimmer and remove the battery
cartridge.
16. Switch off the trimmer and remove the battery
cartridge before doing any maintenance work.
17. When moving the hedge trimmer to another
location, including during work, always remove
the battery cartridge and put the blade cover on
the cutter blades. Never carry or transport the
trimmer with the cutter running. Never grasp the
cutter with your hands.
18. Clean the hedge trimmer and especially the cutter
after use, and before putting the trimmer into
storage for extended periods. Lightly oil the cutter
and put on the cover. The cover supplied with the
unit can be hung on the wall, providing a safe and
practical way to store the hedge trimmer.
19. Store the hedge trimmer with the cover on, in a
dry room. Keep it out of reach of children. Never
store the trimmer outdoors.
