ASSEMBLY
Balancing the strimmer
1. Put the harness on and attach your strimmer to it.
2. Slide clamp up and down, till you feel comfortable with how
the strimmer balances, and how you can manoeuvre it whilst
working.
Make sure the strimmer unit is off, whilst doing
this procedure, to ensure accurate balancing.
• Always use a fuel container with an anti-spill valve.
• Never refuel the machine while the engine is running.
• Always stop the engine and let it cool for a few minutes be-
fore refilling with mixed fuel.
• Make sure there is plenty of ventilation when refilling or mix-
ing fuel (petrol and 2--stroke oil).
• Move the machine at least 10 feet (3 meters) from the refu-
eling point before starting it.
Never start the machine:
• If you have spilt fuel on it. Wipe off the spillage and allow
remaining fuel to evaporate.
• If you have spilt fuel on yourself or your clothes, change your
clothes. Wash any part of your body that has come in contact
with fuel. Use soap and water.
• If the machine is leaking fuel. Check regularly for leaks from
the fuel cap and fuel lines.
• Avoid all skin contact with fuel. Fuel is a skin irritant.

FILLING WITH OIL AND FUEL
FILLING THE UNIT
Untwist and remove the fuel cap. Rest the cap on a dust-
less place. Put mixed fuel into the fuel tank to 80% of the full
capacity. Fasten the fuel cap securely and wipe up any fuel
spillage around the unit.
1. Select bare ground for filling with fuel.
2. Move at least 10 feet (3 metres) away from the fuel
filling point before starting the engine.
3. Stop the engine before refilling the unit with fuel. At that time,
be sure to sufficiently agitate the mixed fuel in the
container.
MIXING THE OIL AND FUEL
HOW TO MIX FUEL
Petrol is flammable. Avoid smoking or bringing
any flame or sparks near fuel. Make sure to stop the engine and
allow it cool before refilling the unit. Select outdoor bare ground
for filling with fuel and move at least 3 m (10 ft) away from the
fuel filling point before starting the engine.
Your strimmer runs off a mix of semi-synthetic 2-stroke oil and
unleaded petrol (40:1). Our petrol tools come with a measuring
jug with guide lines.
Find the side marked 40:1, add your petrol to the first line and
your 2-stroke oil to the second. Replace the jugs lid and shake
the mixture for around a minute.

FILLING WITH OIL AND FUEL
FOR YOUR ENGINE LIFE, AVOID:
1. FUEL WITH NO OIL (RAW PETROL) – It will cause severe
damage to the internal engine parts very quickly.
2. ‘GASOHOL’ – It can cause deterioration of rubber and/orplas-
tic parts and disruption of engine lubrication.
3. OIL FOR 4-STROKE ENGINE USE – It can cause spark plug
fouling, exhaust port blocking, or piston ring sticking.
4. Mixed fuels which have been left unused for a period of one
month or more may clog the carburetor and result in the en-
gine failing to operate properly.
5. In the case of storing the product for a long period of time,
clean the fuel tank after rendering it empty. Next, start the
engine and empty the carburettor of the composite fuel.
6. In the case of scrapping the used mixed oil container, scrap it
only at an authorized repository site.
PRIME THE STRIMMER
Press the priming bulb 5 to 8 times. This will help the strimmer
start with less pulls of the starter cord. If you can’t see fuel enter-
ing the priming bulb please contact SGS.
Move the strimmers switch to the On (I) position.

SET THE CHOKE
For a cold engine, move the choke to the “Start” posi-
tion (closed). Squeeze the throttle lever once.
When re-starting the strimmer (warm engine) you can
move the choke straight into the “Run” position (open).
START THE STRIMMER
Place the strimmer on the ground so the pull start is facing
up towards you. Make sure the cutting attachment is not
touching the ground or might catch on any other object.
Firmly hold the neck of the strimmer with your left hand
and the pull start assembly with your right. The strimmer
should start within 3-5 pulls on a new or cold engine. Slowly
pull the starting rope with your right hand until you feel the
resistance of the rope. Now, pull the pull start hard several
times until the engine fires and starts.
Pull the rope up as vertically as you can. Don’t let the rope
drag on the casing of the strimmer.

OPEN THE CHOKE
Once the machine is running, move the choke to the “Run”
position (open)/ Squeeze the throttle to rev the strimmer
and then let your machine idle for a 30- 40 seconds. Your
strimmer should now be ready to use.
TROUBLESHOOTING
If your strimmer hasn't started using the standard start-
ing procedure, there's a a couple of things you can quickly
check and try.
Checking the Fuel Mix
The most common problem with a strimmer not starting is
that there's a problem with the fuel mix. Double check that
you've used 40 parts fresh unleaded petrol to 1 part 2-stroke
oil (40:1). Check the petrol you've used isn't stale.
Adjusting the Carburetor
Your strimmer needs a balanced combination of air and fuel
reaching the carburetor. This balance needs to be consistent
at all times otherwise your chainsaw will bog down when try-
ing to start, and then die. If you hear the engine bog when
you pull the trigger, the carburetor needs adjusting via the
carb adjustment screw.
