• Do not place a hot hedge trimmer in dry grass or onto
inflammable objects.
• Before starting your work make sure that:

brushwood and branches,

If persons who have blood circulation problems are too
often exposed to vibrations damages to the nervous
system or to blood vessels may occur.
You can reduce vibrations
- by thick and warm working gloves,
- shorter working time (have longer breaks).
See a doctor if your fingers swell, you don't feel well or
your fingers become numb.
Working with the hedge trimmer
Hold the hedge trimmer with both hands on a safe
distance from the body.
• The maximal diameter to cut depends on the wood's
type, age, moisture and hardness.
• Therefore cut very thick branches using branch
shears to your desired length before trimming the
hedge.
• Due to its double sided knives the hedge trimmer can
be guided forward and backward or by oscillating
movements from one to another side.
