General behaviour when working with the hedge
trimmer
• Never work alone. Another person should stay close
enough to hear calls for help.
• Keep children, bystanders and animals at a distance
(15m min.) from your working area.
• Do not work on snow, ice or other slippery ground –
slip hazard.
• Do not work under insufficient light conditions (e.g.
fog, rain, snow flurry or twilight).
• Scare animals off the hedge before starting to cut in
order to prevent them from being injured.
• Provide for a safe and cleaned workplace. Remove
from the working area objects which might be thrown
off.
• Avoid abnormal posture. Keep at any time the ba-
lance. Do not work with the upper part of the body
leaned forward.
• Operate the hedge trimmer only with safe standing
position.
