Maintenance
WARNING. Before performing any maintenance on this blower,
stop the engine and disconnect the spark plug wire.
Checking the spark plug
Check the spark plug (4) every 10 - 15 hours of use.
1. Remove the spark plug cover.
2. Use a spark plug wrench to remove the spark plug, by
turning it counter-clockwise.
3. Clean and adjust the spark plug gap to 0.6 - 0.7mm. Replace
any damaged or visibly worn plug with a CHAMPION CJ8,
NGK BM6A or equivalent spark plug.
4. Install the spark plug finger tight in the cylinder head, then
tighten it firmly with the spark plug wrench.
Air filter
The air filter should be checked approximately every 10 hours
of use, or more frequently in dusty areas.
1. Unclip the filter cover (2) on the side, hinge around and
remove the cover and filter element.
2. Inspect the element. If the element is distorted or damaged,
replace it with a new one.
3. Wash the filter in detergent and water. Rinse the filter
thoroughly. Squeeze out excess water. Allow it to dry
completely before reinstalling.
4. Install the element and cover and then replace the cover and
clip into place.
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:
- Turn the idle screw (9) clockwise to increase engine idle speed.
- Turn the idle screw counter clockwise to decrease engine idle
speed.
IMPORTANT. Blower tubes and intake cover must be installed while
adjusting engine idle speed. Engine idle speed will also be affected
if either the intake cover or blower tubes are blocked, damaged or
incorrectly installed.
Storage
• Be careful not to hit or cut the fuel tank, or fuel lines, when
the unit is placed on the ground.
• Do not let the tool fall, or it may be damaged and become
unsafe.
• When you finish working, clean the unit completely.
• Inspect the entire unit and tubes for damage, including loose
or missing components, and repair anything necessary.
• Store the unit 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.
• Ensure that fuel and oil is stored in a safe place, away from
heat, direct sunlight, any source of ignition, and out of reach
of children.
Storage for an extended period
Whenever the machine is not used for a long period of time,
proceed as follows:
• Give the leaf blower an overall cleaning and a thorough check.
• Empty the fuel tank completely, then clean the carburettor 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.
Troubleshooting
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.
