Safety Precautions
Special safety precautions must be observed when working with this tool.
It is important that you read and fully understand, then observe all of the
following safety precautions and warnings.
•Careless of improper use of the blower may case serious or fatal injuries.
•Observe all applicable local safety regulations, standards and ordinances.
•Minors should never be allowed to use the blower.
•Bystanders, especially children and animals, should not be allowed in the
area where a blower is being used.
•The operator of the blower has the responsibility to avoid injury to third
parties and to avoid damage to all property.
•Don't lend or rent the blower to someone else without supplying them with
a copy of this manual for their reference. Ensure that anyone using the
blower is aware of the instructions in this manual and understand them.
Fitness
•To use the blower, you must be fit to use it, such as:
•Be rested, with good health and good mental conditions.
•If you get tired, take a break.
2

•Do not operate the blower if you are under the influence of any drugs or
alcohol that may impair your vision, dexterity or judgement.
Safety clothing and equipment
•Clothing must be sturdy and snug-fitting, but allowing for complete
freedom of movement – industrial safety clothing is recommended.
•Avoid loose-fitting jackets, scarves, neck-ties, jewellery, flared trousers,
cuffed trousers, unconfined long hair or anything else that could get
caught in the air intake.
•Wear sturdy boots with non-slip soles. Steel-toed safety boots are
recommended.
•Wear safety googles, glasses or a face shield.
•Wear sound barriers (ear plugs or mufflers) to protect your hearing.
•Wear heavy-duty, non-slip gloves, preferably made of chrome leather.
•Never touch a hot cylinder or muffler, as burns may result.
Refuelling
•Always stop the engine before refuelling.
•Petrol is an extremely flammable fuel. Do not smoke or have any other
flames near petrol. Do not put fuel into a hot engine – fuel may spill and
cause a fire.
•Remove the fuel filler cap on the unit carefully to ensure that any pressure
build-up inside the tank may release slowly.
•Add petrol to the blower in a well-ventilated location outdoors. Wipe up
any spilled fuel before starting the blower.
•Take care not to get petrol on your clothing. If you get petrol on your
clothes, change them immediately.
•Unit vibrations can cause an improperly tightened fuel cap to loosen, or
even come off completely, spilling quantities of fuel. To avoid this hazard,
check the fuel cap occasionally to ensure that it is still tightly sealed.
•On units with a screw cap, tighten the cap by hand with as much force as
comfortably possible. On units with a hinged handle on the fuel cap,
tighten as described in the chapter 'Fuelling'.
•Check for fuel leakage while refuelling and during operation. If a fuel leak is
found, do not start or run the engine until the leak is fixed.
•Store petrol and oil in properly labelled, approved safety cans or tanks.
Transporting unit
•Always stop the engine before transporting.
•Protect the unit in a vehicle to prevent it tipping over, spilling fuel or being
damaged.
Pre use checklist
•Throttle trigger must move freely and spring back to the idle position when
released.
•The stop switch must move easily to 'Off'.
•Tightness of the spark plug cap – if the cap is loose, sparks may occur and
ignite escaping fuel vapour.

Starting
•Start the engine at least metres away from the location where you
refuelled the blower, outdoors only.
•To reduce the risk or breathing toxic fumes, never start or run the unit in a
confined location.
•Place the unit on the ground in an open area.
•Make sure you have good balance and secure footing.
•Hold the unit securely.
The unit is a one-person unit. Do not allow other persons to be near while
running the unit – even when starting.
During operation
WARNING: your blower produces toxic exhaust fumes when the engine is
running. These gases (such as carbon monoxide) may be colourless and
odourless. To reduce the risk of serious or fatal injury from breathing toxic fumes,
never run the blower indoors or in poorly ventilated locations.
Ensure proper ventilation when working in trenches, hollows or other confined
areas.
To reduce the risk of igniting the combustible fuel vapours and causing a fire,
never smoke while working with, or standing next to the blower.
Always hold the unit firmly – always make sure you have firm and sturdy footing.
Examine the working area – do not direct air blasts towards bystanders or
animals, as the air flow can blow small objects at great speed.
Take care in slippery conditions, such as on ice, in the wet or snow, or while on
slopes or uneven ground.
Watch out for obstacles, such as roots, ditches, holes or rubbish that could cause
you to trip or stumble.
Vibrations
Prolonged use of the unit may result in vibration-induced circulation problems in
the hands. No general recommendation can be given for the length of usage as
it depends on several factors.
The recommended period of usage can be prolonged by:
•Hand protection (wearing warm gloves.)
•Taking breaks.
The recommended period of usage is shortened by:
•Any personal tendency to suffer from poor circulation (with symptoms
such as frequently cold fingers, itching etc..)
•Low ambient temperatures.
•Gripping force (A tight grip hinders circulation.)
Continual and regular users should monitor the conditions of their hands and
fingers closely.

Storing fuel
Only mix sufficient fuel for a few months work. Store mixed fuel in an approved
safety-type fuel container, in a dry and safe location.
•Thoroughly shake the mixture in the container before fuelling the blower.
Beware that pressure may build up in the container, so open it slowly and
carefully.
•Clean the fuel tank and fuel container from time to time. Dispose of the
cleaning fluid at a properly authorized disposal station.
•Before refuelling, clean the filler cap and the area around it to ensure that
no dirt or other waste falls into the tank.
•Position the unit so that the filler cap is facing upwards. Take care not to
spill the fuel when refuelling, and do not overfill the tank.
•After refuelling, tighten the filler cap by hand as securely as possible.
Change the fuel filter once a year
•Drain the fuel tank.

Operation instructions
First time use (breaking in)
A new machine should not be run at high speed. This avoids unnecessarily high
loads during the break-in period. The frictional resistances in the engine are
greater during this period. The engine develops it's maximum power after about
5 to 15 tank fillings.
During operation
After a long period of full-throttle operation, allow the engine to run for a short
time at idle speed so that the heat of the engine can be dissipated by the flow of
cooling air. The protects the engine-mounted components (ignition, carburettor
etc...) from thermal overload.
After use
Wait for the engine to cool down. To avoid condensation, fill the fuel tank and
keep the unit in a dry place until you need it again. If you will be storing the unit
unused for a long period of time, see the chapter “storing the machine”.
Cleaning the air filter
Dirty air filters reduce engine power, increase fuel consumption and make starting
more difficult.
•Close the choke.
•Pull A and remove the air filter cover.
•Remove the filter from the cover and
inspect it. If it is dirty or damaged, either
clean the filter or fit a new one.
•Install the filter.
•Fit the cover and tighten the screws.
Carburettor
Your carburettor comes from the factory with a standard setting. This setting will
provide the optimum fuel-air mixture under most operating conditions.
The high speed screw alters the engine power output and the maximum engine
speed. If the setting is too lean, there is risk of engine damage due to
insufficient lubrication and overheating.
The Spark Plug
If the engine is down on power, difficult to start or is running poorly and idle
speed, check the spark plug.
•Remove the spark plug. (See
“starting/stopping the engine”)
•Check the electrode gap A
(0.6~0.7mm) and adjust as
necessary.

A
A

Rectify any problems that may have caused fouling of the spark plug:
•Too much oil in the fuel mixture
•Dirty air filter
•Unfavourable running conditions
Fit a new spark plug after every 100 operating hours or so, or sooner if the
electrodes are badly eroded.
•If the spark plug comes with a detachable adapter nut, screw it firmly.
•Press the cap firmly onto the spark plug.
Engine behaviour
If the engine behaviour and performance is unsatisfactory, even though the air
filter is clean and the carburettor is properly adjusted, they cause may be in the
muffler.
Have your muffler checked for contamination by a service center.
Storing the machine
If storing the unit for periods of months or longer:
•Clean the fuel tank.
•Run the engine until the carburettor is dry – this helps to prevent the
carburettor diaphragms from sticking together.
•Thoroughly clean the machine – pay special attention to the cylinder and
air filter.
•Store the machine in a dry, locked location out of reach of children or other
unauthorised persons.
•Do not expose the container to direct sunlight for unnecessarily long
periods. UV rays can make the container material brittle, which could result
in leakage or breakage.
Minimising wear and avoiding damage
Observing the instructions in this manual will reduce the risk of wear or damage
to the blower.
The blower must be operated, maintained and stored with the due care and
attention described in this manual.
The user is responsible for all damage caused by non-observance of the safety
precautions, operating and maintenance instructions in this manual. This includes,
in particular:
•Alterations or modifications to the product not approved by Kogan.com
•Using non-approved accessories, power tools or cutting tools
•Using the blower for purposes for which it was not designed
•Continuing to use the blower with defective components
10

Maintenance and repair
All maintenance work should be performed by the owner, or if not, they should
be performed by a commercial hardware workshop.
If these operations are not carried out as specified, the user assumes
responsibility for any damage that may occur. Among other things, this includes:
•Damage to the engine due to neglect or deficient maintenance, incorrect
carburettor adjustment or inadequate cleaning of the cooling air inlets.
•Corrosion and other consequential damage resulting from improper
storage.
