FUEL
Petrol is very ammable. Avoid smoking or fuelling the hedge
trimmer anywhere near a ame or sparks. Allow the engine to cool be-
fore re-fuelling. Fuel the engine at least 3m away from your work area.
• Use a mixture of 25 parts unleaded petrol to 1 part 2-stroke engine oil (25:1)
and mix in the mixing bottle provided. Agitate well.
• Unscrew the fuel cap, and fuel the machine to 80% capacity. Fasten the fuel
cap tightly and wipe up any spillage.
• Ensure that any stored petrol/oil mixture ( 2-stroke) is clearly marked in sepa-
rate can and only stored for 4-6 weeks. If the hedge trimmer is not going to
be used for a long period, drain the mixture from the fuel tank, start the engine
and drain the carburettor of any remaining fuel.
• Dispose of any unwanted 2-stroke mixture at an authorised recycling point.

OPERATION
Before use, check that the cutter blade is not damaged, the handles controls
are easy to use and that the STOP On/Off switch operates correctly.
The idling speed should be set so that the blades do not move whilst the en-
gine is idling.
1. Pull the STOP switch backwards.
2. Squeeze lock lever A and then the throttle lever B.
3. Keeping throttle lever B depressed, press throttle lock C inward.
4. Keeping throttle lock C depressed, release throttle lever B - this will lock
throttle lever B in position.
5. Gently depress the primer pump 7-10 times until fuel comes into the primer
pump.
6. Move the choke lever to ‘open’.
7. Holding the unit down rmly, slowly pull the starter cord until resistance is
felt and continue with a sharp pull until the engine res.
8. Move the choke lever to ‘closed’ and pull the starter cord again until the
engine res.
9. As soon as the engine starts, squeeze and release the throttle, thus releas-
ing the throttle lever B so that the engine can idle.
10. Run the engine for approximately one minute at moderate speed before
applying full speed.
• If starting a warm engine, try procedures 1, 7 and 8. If the engine does not
start repeat the whole procedure from step 1.
To Stop the Machine:-
• Release the throttle lever completely and push the STOP switch forward.

Always hold the hedge trimmer rmly with both hands when using.
Before cutting ensure that the blades are running at full speed and be aware that
the blades may keep moving after you have released the throttle.
This hedge trimmer has a twist handle which rotates through 180 degrees and is
ideal for cutting shaped hedges.
It is advisable to cut a hedge from the bottom up sweeping the cutter bar in an arc
as you move along the hedge. The double edged cutter blades allows use by left or
right handed operators.
To cut the top of the hedge, hold the cutter bar at an angle of 0-10 degrees as you
swing the hedge trimmer horizontally. Sweep the cutter bar in an arc towards the
outside of the hedge so that the cuttings are swept onto the ground.
Pay special attention when cutting hedges which are laid out along a wire fence. If
the blades makes contact with the wire damage may occur.
Do not use the hedge trimmer for long periods at a time - take a break of 10-15
mins after 50 mins use or after using one tank of fuel.
If the blades hit a stone, wire or other foreign object, turn off the engine and check
for any damage immediately. Replace any damaged blades before continuing.
Do not attempt to remove any twigs or branches jammed in the cutter blades with-
out rst turning the machine off.
