General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

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 or its own cord. 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. Keep cable away from cutting area. During operation the cable may be hidden in shrubs and can be accidentally cut by the blade.

5. Do not use the hedge trimmer in the rain or in wet or very damp conditions. The electric motor is not waterproof.

6. First-time users should have an experienced hedge trimmer user show them how to use the trimmer.

7. 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.

8. 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.

9. Never use the trimmer when under the influence of alcohol, drugs or medication.

10. Check to make sure that the voltage and frequency of the power supply correspond to the specifications given on the identification plate. We recommend the use of a residual-current-operated circuit breaker (ground-fault circuit interrupter) with a tripping current of 30 mA or less, or an earth leakage current protector.

11. 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.

12. Before starting work check to make sure that the trimmer is in good and safe working order. Ensure guards are fitted properly. Check cable for damage before starting work and replace if necessary.
    The hedge trimmer must not be used unless fully assembled.

13. Keep cable away from the cutting area. Always work in such a way that the extension power cord is behind you.

14. Remove plug from the mains immediately if cable is damaged or cut.

15. Make sure you have a secure footing before starting operation.

16. Hold the tool firmly when using the tool.

17. Do not operate the tool at no-load unnecessarily.

18. Immediately switch off the motor and unplug the mains plug if the cutter should come into contact with a fence or other hard object. Check the cutter for damage, and if damaged repair immediately.

19. Before checking the cutter, taking care of faults, or removing material caught in the cutter, always switch off the trimmer and unplug the mains plug.

20. Switch off the trimmer and disconnect and secure the mains plug before doing any maintenance work.

21. When moving the hedge trimmer to another location, including during work, always unplug the mains plug 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.

22. 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.

23. Store the hedge trimmer with the cover on, in a dry room. Keep it out of reach of children. Never store the trimmer outdoors.

24. Do not operate the tool at no-load unnecessarily.

SAVE THESE INSTRUCTIONS.

WARNING: DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.
