9. 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.
10. 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!
11. MAINTENANCE INSTRUCTIONS
ATTENTION! The following instructions are valid for standard working conditions. In case of aggravated
conditions such as heavy dust contents, wood with a high content of resin or longer working periods the
interval must be shortened accordingly.
Before you start work check the following:
• Throttle
• Visually check the whole machine
• Position of the knife bar or the cutting knife
• Degree of sharpness
• Wear and tear or the guiding bar damage
After you fi nish working check the whole machine and clean it.
Regularly check and maintain the following:
• Air fi lter (clean if necessary)
• Spark plugs pict. a; item 6 (if replacement is needed)
• Cutting knife sharpness (clean well and lubricate)
When repairing or maintaining the hedge trimmer, have it always switched off.
12. FUEL DATA
Refuelling
Mix unleaded petrol with brand oil for two-stroke engines with air cooling in the 1:30 ratio. This means that
for example 5 l of petrol is mixed with 0,16 l of oil.
13. REPAIRS/ENGINE FAILURES
Repairs that require special professional knowledge should be carried out by authorised service centres.
Unprofessional interference can damage the machine or endanger your safety.
Engine failures
Failure
Cause
Remedy

1. Empty tank
1. Fill up
2. Flooded engine
2. Close the throttle, start for several times,
in case of need take out the spark plug
and dry it

the electrodes) electrodes too
far away
3. Clean the spark plug, check its
temperature, replace if needed.
Adjust at 0.6-0.7 mm
4. Fouled carburettor or its jets
4. Clean the carburettor with air
5. Damaged spark plug connection or
damaged spark plug

8. Adjust the ignition module louver
(0.3-0.4 mm)
Engine would not stop
1. Spark plug is light grey with signs of
heating (heating drops)
1. Install a spark plug with a higher thermal
value
2. Remains of carbon in the combustion
area
2. Clean cylinder head, piston bottom and
cylinder channels
