FUELLING AND LUBRICATION
Fuel
Use regular grade unleaded gasoline mixed with 40:1 custom 2-cycle engine
oil for best results. Use mixing ratios in the fuel mixing table below.
WARNING: Never use straight gasoline in your unit. This will cause permanent
engine damage and void the manufacturer’s warranty for the product. Never
use a fuel mixture that has been stored for over 90 days.
WARNING: If 2-cycle lubricant other than Talon Custom Lubricant is to be
used, it must be premium grade oil for 2-cycle air cooled engines mixed at a
30:1 ratio. Do not use any 2-cycle oil product with a recommended mixing ratio
of 100:1. If insufficient lubrication is the cause of engine damage, it voids the
manufacturer’s engine warranty.
Mixing fuel
Pour the oil and fuel in a container. Mix them thoroughly during 1 min.
Add fuel in the machine
Open the fuel tank by removing the cap. Pour the mixing fuel correctly in the
fuel tank. Wipe any spillage. Close the fuel tank.
Recommended fuels
Some conventional gasolines are being blended with oxygenates such as
alcohol or an ether compound to meet clean air standards. The engine is
designed to operate satisfactorily on any gasoline for automotive use including
oxygenated gasoline.
Precautions for fueling
Always use extreme care when handling fuel! Fuel is highly flammable.
Never attempt to fuel the blower if the fuel system components are
damaged or are leaking.
Never attempt to refuel the engine while it is running or still warm, allow
it to cool before fueling.
Never smoke or light any fires near the blower or fuels.
Always transport and store fuels in an approved container.
Never place flammable material close to the engine muffler.
Never operate the blower without a properly functioning muffler and
spark arrestor installed.
Never operate the blower unless it is properly assembled and in good
working condition.

Do not use petrol which contains ethanol or methanol as it may damage
the fuel lines and other engine parts.
Mix only enough fuel for your immediate needs. If fuel must be stored
longer than 30 days, it should first be treated with a stabilizer or similar
product.

Blower operations
1. Use the blower for trees, shrubs, flower beds, and hard-to-clean areas.
2. Use the unit around buildings and for other normal cleaning procedures.
3. Use the blower around walls, overhangs, fences, and screens.
4. We recommend that a face mask be worn when operating the blower in dusty areas.
5. Stand away from the debris, at a distance that will easily allow you to control the direction
of blown debris. Never blow debris in direction of bystanders.
6. To control velocity of air stream, blower can be operated at any speed between idle and
full throttle.
Experience with the unit will help you determine the amount of airflow necessary for each
application.
7. To reduce sound levels, limit the number of pieces of equipment used at any one time.
8. Check your equipment before operation, especially the muffler, air intakes and air filters.
9. Use rakes and brooms to loosen debris before blowing. In dusty conditions, slightly
dampen surfaces when water is available.
10. Conserve water by using power blowers instead of hoses for many lawn and garden
applications, including areas such as gutters, screens, patios, grills, porches and
gardens.
11. Use intermediate tube plus nozzle of your choice so the air stream can work close to the
ground.
12. After using blowers and other equipment, CLEAN UP! Dispose of debris in trash
receptacles.
Operating instructions
1. Follow the instructions “STARTING A COLD ENGINE”.
2. Once unit is running, place unit on your back by slipping arms through the shoulder straps
as if you were putting on a backpack.
3. When preparing to clear an area of debris, always position yourself so that you can control
the direction debris will be blown.
4. The control handle and the flexibility of the blower tube assembly will allow you to clear the
most hard-to-reach areas.
5. The hand grip, throttle trigger, lock-out button and on/off ignition switch are all mounted on
a swivel handle that offers a wide range of operating positions and comfort.

MAINTENANCE
Cleaning the Air Filter
Dirty air filers reduce engine power increase fuel consumption and make starting more
difficult.
Turn choke knob to
Release the two screws (1) and pull off the filter cover (2)
Remove the filter from the cover and inspect it - if it is dirty or damaged, clean the filter
or fit a new one.
Install the main filter and prefilter elements in the filter cover.
Fit the cover on the filter base and tighten it down firmly.
Carburetor
Your carburetor shall be only be checked by professional repairman,
never try to do it by yourself.
Checking the Spark Plug
If engine is down on power, difficult to start or runs poorly at idle speed
first check the spark plug.
Remove the spark plug - see "Starting / Stopping the Engine"
Check electrode gap (A) and readjust if necessary – see "Specifications".

Storing the Machine
For periods of about 3 months or longer
Drain and clean the fuel tank in a well-ventilated area.
Run engine until carburetor is dry - this helps prevent carburetor diaphragms sticking
together.
Thoroughly clean the machine- pay special attention to the cylinder fins and air filter.
Store the machine in a dry, high or locked location - out of the reach of children and
other unauthorized 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 leaks or breakage.
