•
Unit vibrations can cause an improperly tightened fuel cap to l oosen or come off and spill fuel.
− In order to reduce the risk of fuel spillage and fire, tighten the fuel cap.
− On units with a screw c ap: t ighten the cap firmly by hand.
− On units with a hinged handle on the fuel cap: tighten as described in the “Fuelling” section.
•
Check for any fuel leakage while refuell ing and dur ing operation. If fuel leakage is found, do not start
or run the engine until the leakage has been fixed.
•
Store fuel and oil in prop erly labelled, approved safety-type cans.
•
Always stop the engine when you are transporting the blower.
•
When transferring the blower in a vehicle, protect it properly to prevent turnovers, fuel spillages and
potential damages. When the unit is not in use, put it down so that it does not endanger others.
•
Before starting, check the following:
− Throttle trigger must move freely and spring back to idle position when released.
− Stop switch must move easily to "OFF".
− Tighten the spark plug cap if it is loose. Sparks may occur and ignite the escaping fuel vapours.
•
Starting
− Start the engine at leas t 3m from the fuelling spot , outdoor s only.
− To reduce the risk of breathing toxic fumes, never start or run your unit in confined spaces.
− Place the unit on firm ground in an open area.
− Make sure you have good balance and secure footing.
− Hold the unit securely.
− Do not allow other persons to be near the running unit, even when starting.
•
During operation
− Warning! Your blower produces toxic exhaust fumes when the engine is running. These gases (e.g.
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 v entilation when working in trenches, hollows or other confi ned areas.
− To reduce the risk of igniting the combustible fuel vapour and causing a fire, never smoke while working
with or standing next t o the blower.
− Always hold your unit firml y – make sure you always have a firm and secure footing.
− Examine the work area: Do not direct the air blast towards bystanders since the air flow can blow small
objects at great speed.
•
Be cautious in slippery conditions.
− On ice, snow or wet/damp environments.
− On slopes or uneven ground.
•
Watch out for obstacles.
− Roots, ditches, holes or rubbish, which could cause you to trip or stumble.

Breaking-In
A new machine should not be immediately ru n at high engine speeds, as the internal components need to “bedin”. It is recommended to allow the e ng ine to fully warm up before beginning to increase engine speed. For the
first hour of engine use, avoid rapid changes in engi ne speed. The engine develops 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 while at idle speed so that the heat can
be dissipated by a flow of c ooling air. This protects the engine-mounted com ponents (ignition, carburettor, etc.)
from thermal overload.
After Finishing Work
Release the throttle and place the engine ON/OFF switch in the “OFF” position, then wait for the engine to cool
down. Leave some fuel in the tank and store t he u ni t upright in a dry place out of the reac h of children or
unauthorised persons. For storing for lo ng periods of time, see the "Storing t he Mac hine” section.
Maintenance and Stor age
•
Do not attempt any maintenance or repair work not described i n this user’s manual. Have such work
performed at your service shop only.
•
Never modify your power t ool i n any wa y as this could result in serious i njury.
•
Always stop the engine and disconnect the spark plug cap before doing any maintenance/repair work or
cleaning the mac hine (exception: carburettor and idle adjustments).
•
Always clean dust and dirt off the machine after finis hing work.
•
Do not store or service your unit near any fire or flame.
•
Check the fuel cap regularly for any signs of leakages.
•
Use only the approved spark plug and make sure it is in good condition.
•
Inspect the ignition wires (insulatio n in good condition, secure connection).
•
To reduce the risk of fire due to ignition outside of t he cyli nder, move the stop switch to “OFF” before turning
the engine over on the starter with the spark plug c ap removed or the spark plug unscrewed.
•
Check the condition of the exhaust periodically.
•
To avoid the risk of f ire or hearing loss, do not operate your unit if the muffler is damaged or missing.
•
Never touch a hot muffler or serious burns will result.
Cleaning the Air Filter
Dirty air filters reduce engine power, incr ease fuel
consumption and make starting more difficult.
If there is a noticeable los s of engine power:
•
Close the choke.
•
Pull A and remove the air filter cover.
•
Remove the filter fr om the cover and inspect it. If it is dirty
8
Page 11

or damaged, clean the filter with warm water and mild det ergent and allow to dry, or fit a new one. Place a
few drops of oil on the air filter element and squeeze it a few times to distribute the oil.
•
Install the filter element and re-install the air filte r cover.
Carburettor
Your carburettor comes factory set for optimum fuel-air mixture under most operating conditio ns.
The high speed scr ew alters the engine power output and the maximum unloaded engine speed. If the setting is
too lean, there is a risk of engine damage due to insuffic ient lubrication and overheating.
Checking the Spark Plug
If engine is down on power, dif ficult to start or runs poorly at idle
speed, first check the spark plug.
•
Remove the spark plug using the supplied spanner and
clean off any carbon build-up with a wire brush.
•
Check the electrode gap (A) (0.6 – 0.7mm) and adjust if
necessary.
•
Rectify any problems which may be affecting the spark plug:
− Too much oil in fuel mixture (oi ly electrodes).
− Dirty air filter.
Fit a new spark plug after about 100
operating hours, or sooner if the electrodes
are badly eroded.
•
If the spark plug comes with a
detachable connector, firmly tighten it.
•
Press the cap firmly onto t he spark plug.
Engine Running Behavi our
If engine running behaviour is unsatisfactory even though the air filter is clean and the carburett or properly
adjusted, the cause may be in the muffler. Have the muffler checked for carbon build-up by the manufacturer or
an authorised service centre.
Storing the Machine
For periods of 3 months or longer:
•
Drain t he fuel tank.
•
Run the engine until carburettor is dry. This helps pr event the carburettor diaphragms from stick ing together.
•
Thoroughly cle an the machine. Pay special attention to the cylinder and air filter.
•
Remove the spark plug and pour appr oximately 20ml of engine oil into the cylinder. Slowl y pull the start cord
several times, then re-inst all the spark plug.
•
Store the machine in a dry, secure location out of the reach of children and unauthorised per sons.
