A simple procedure with the 2 stroke engine. Move the choke lever to the full on
position. Next hold down the throttle switch in the full on position. If your petrol
strimmer has an on and off switch then set the switch to on. Depress the primer bulb
a couple of times to get fresh fuel in to the carburetor. Place the unit on the ground
and make sharp brisk pulls on the starter cord. When you hear that the engine is
trying to run then reset the choke to half level and pull again on the starter cord.
The engine should begin running. You need to keep the throttle at full power and
allow the engine to warm up for about 10 seconds or so. Turn the choke off and allow
the engine to tick over for about 30 seconds. It should now be fully warmed up and
if you need to start it again, it should start without the need for the choke.
Why does my petrol strimmer not start?
There are several causes that result in the engine not starting. You need to check
if the fuel mixture you are using is fresh. Is the on switch on? Is the spark plug
functioning properly? Is the air filter dirty? Is the fuel filter clogged? Is the
Checking these common symptoms will usually rectify any starting problems.
Why does trimmer line always break?
You will soon discover that trimmer line will break due to line crowding. This happens
when you hold the trimmer head too close to any hard objects such as rocks, bricks
and fencing. By keeping the line at full extension and not crowding it will reduce
line breakage problems.
Why won’t the trimmer head turn when the throttle is engaged?
This happens when the drive shaft is not fully engaged. It also happens if the flexible
cable is broken.
What type of spark plug do I use with a petrol strimmer?
Each petrol strimmer will vary. Usually the spark plug required is that of RCJ-8Y
or RCJ-6Y. But do check your handbook.
What is the correct spark plug gap?
How do I lubricate the driveshaft?
With a curved shaft petrol strimmer you need to remove the driveshaft housing to
obtain access to the flex shaft. Simply pull the shaft out and clean it up. Then
apply the shaft lubricant and replace the driveshaft housing.
With a straight shaft petrol strimmer you have to remove the gearbox. You do this
by unscrewing it. Then pull the shaft out of the bottom and clean and lubricate
it. Always remember to reassemble your petrol strimmer in the correct manner.
Is the fuel filter easy to locate?
Yes. You will find the fuel filter at the end of the fuel line in the fuel tank.
The fuel filter needs to be changed annually at the least. To take the fuel filter
out simply drain any fuel from the fuel pipes and pull the filter out of the tank
and remove it from the fuel line. Place a new fuel filter on the fuel line and drop
it back in to the tank.
How often should I clean the air filter?
Approximately after every 4 or 5 hours of use. You can clean the air filter using
warm soapy water and then allow it to dry before replacing.
What is the oil and fuel mix ratio with a petrol strimmer?
Most petrol strimmers are powered by a 2 stroke engine. These engines require lubricating
but do not have a regular oil sump. So to lubricate them, oil has to mixed with the
fuel. New models today are made so that the mix ratio is 50/1. Older versions of
the petrol strimmer have mix ratios of 40/1 or even 32/1. Check your handbook or
on the engine housing of your version to see which ratio your model requires. Remember
that oil and fuel will separate over time. So if you store you mix in a canister
you need to swirl it around before refilling. Never shake it.
Why do I have to use a oil and fuel mix?
A 2 stroke engine does not have a regular oil reservoir. So to keep the engine lubricated
at all times, oil has to be added to the fuel. Failing to add oil to your fuel will
mean that the engine will have no lubrication at all. Within a couple of minutes
the engine will overheat and seize, rendering it useless.
Which fuel do I use with a petrol strimmer?
Regular unleaded gasoline is the fuel of choice. You can use fuel that has a maximum
of 10% alcohol in it. Never use diesel fuels with a petrol strimmer.
Is it ok to leave fuel in the petrol strimmer?
You shouldn’t do this. Particularly over a long period of time. If you do then deposits
will form in the fuel system and cause you all sorts of working problems. So if you
will not be using the petrol strimmer for an extended period of time, always drain
the fuel tank and run the machine dry.

In an ideal world one would be able to pop down to the local store, purchase the
required piece of gardening equipment, return home and just complete any gardening
job without any problems or hindrance. Sounds good doesn’t it. Bong, reality emerges.
Now the petrol strimmer is not the most complicated of man made inventions. In fact
it is quite the opposite. You have an engine at the top of a shaft which powers the
cutting head at the bottom of the shaft. Just power up the machine and away you go.
Not rocket science is it? Bong, reality emerges.
Now manufacturers spend a lot of money with research and development in order to
manufacture a high quality model that outperforms their rivals. And many strimmers
are actually very good. To be honest over the last 10 years or so, new models of
the petrol strimmer are just getting better and better. However what these manufacturers
fail to do is supply their new excellent machines with adequate handbooks giving
you all the information you require about your particular machine. This is why there
are so many similar questions asked by fellow petrol users on a regular basis. The
questions vary from the simple to the complicated, yet time after time, the same
questions just keep emerging. Lets hope one day that one of the major manufacturers
compliments their great machines with a suitable handbook we can all appreciate and
