571551 - Petrol Hedge Trimmer Owner’s Manual - May 2014
8 Hedge trimmer functioning
The Morrison hedge trimmer is equipped with quick stop
function which stops the knife immediately once the throttle is
released to prevent a possible accident.
If you want to switch off the machine, you must move the
switch
(pict. a; item 3
) into the “OFF”position.
• When cutting hedges comply with regulations valid in the
relevant country and local regulations.
• If the branches are bigger than the maximal cutting power,
they must be removed by other machinery.
• If heavy pruning is required, you should work in stages.
9 Work safely and
with prudence
1. Hold the hedge trimmer safely in both hands!
2. Trim and cut only wood and wooden objects!
3. Work with consideration and do not threaten anyone when
cutting. Work calmly with prudence!
4. Work when it is light and visible!
5. Constantly watch the cutting knife!
6. Never cut below shoulder height!
7. Work only with a sharpened and correctly installed
cutting knife!
8. Do not stand on a ladder when working!
9. Work only on sound and stable ground!
10 Maintenance Instructions
ATTENTION! The following instructions are
valid for standard working conditions. In case

When repairing or maintaining the hedge trimmer, have it
always switched off.
