Servicing
• It is recommended once you first use your petrol blower
have it serviced after 15 hours of use.
• From thereafter, service the petrol blower every 2 years.
Storage and maintenance after use
• When you finish working, clean the petrol blower completely.
• Inspect the entire blower and tubes for damage,
including loose or missing components, and repair
anything necessary.
• Store the petrol blower away from direct sunlight.
• Do not store in a nylon bag as this can encourage the
formation of mould.
• Use a small brush to clean off the outside of the unit
and keep the air vents free from obstructions. Do not
use water or a hose to clean the unit.
Whenever the machine is not used for a long period of time,
proceed as follows:
• Give the petrol blower an overall cleaning and a
thorough check.
• Empty the fuel tank completely, then clean the
carburetor and lines by running the blower until it
stops from lack of fuel.
• Protect all metal engine parts from corrosion by coating
them with oil.
• Remove the spark plug, put several drops of oil into the
cylinder through the spark plug hole and then pull the
recoil starter 2 to 3 times in order to distribute the oil
evenly. Replace the spark plug and spark plug cover.
• Clean the air filter as described in the air filter section.
Problems
Power loss or sudden stopping of the engine
• Check whether the fuel tank is empty.
• There is water in the mixture. Drain and rinse the fuel
system with petrol.
• The air filter is dirty. Clean the air filter.
Starting a flooded engine
• Disconnect the spark plug lead, and use the plug wrench
to remove the spark plug in a counter clockwise direction.
• If the spark plug is fouled or is soaked with fuel, clean or
replace the plug as required.
• Clean excess fuel from the combustion chamber by
cranking the engine several times while the spark plug
is removed.
• Install the spark plug and firmly tighten it with the spark
plug wrench.
• Repeat the starting procedure as if the blower was
already warm.
Adjusting the engine idle speed
• If your blower is delivering poor performance or
running roughly then you may need to adjust the
engine idle speed.
• Start the blower engine.
• Run the engine at idle speed until operating temperature
is reached, approximately 2–3 minutes.
• Use a screwdriver to adjust
the engine idle speed to
(2800–3000) RPM.
• Turn the idle screw clockwise
to increase engine idle speed.
• Turn the idle screw counter
clockwise to decrease engine
idle speed.
