9. CARBURETOR ADJUSTMENT

WARNING! Incorrect adjustment may cause
damage to your unit. If the engine does not run
well after adjusting the carburetor, please contact the
Helpline for advice.
The idle adjustment screw (n) (See Fig. M) is used to
adjust the engine rotation speed. Whilst the throttle lever
is set to the lowest speed position, turn the idle screw
clockwise to increase idle speed; counterclockwise to
decrease idle speed.
If the blade or cutter continues to rotate, or the engine
stops with the throttle lever in the idle position make the
necessary adjustments to the 'idle adjustment' screw.
DANGER! When carburetor adjustment is
completed, the cutting attachment should not
turn at idle.
STORAGE
Proper storage preparation is essential to keep your
brushcutter trouble free and looking good. The following
steps will help to keep rust and corrosion from impairing
your brushcutter function and appearance and will make the
engine easier to start when you use the brushcutter again.
1. Cleaning
Wash the blade, including the area around the cutter head.
Wash the engine by hand and be careful to prevent water
from entering the air filter.
NOTE: A garden hose or pressure washing equipment
will force water into the air filter. Water in the air filter will
allow water to enter the carburetor or engine, causing
damage.
Water on a hot engine can cause damage. If the engine
has been running, allow it to cool for at least 1/2 hour
before washing.
After washing the cutter, wipe dry all accessible surfaces.
Start the engine outdoors, and let it run until it reaches
normal operating temperature to evaporate any water
remaining on the engine. Stop the engine and allow it to cool.
After the cutter is clean and dry, coat areas that may rust
with a light film of oil. Lubricate the control cable cores
with a silicone spray lubricant.
2. Fuel
Petrol will oxidise and deteriorate during storage. Old fuel
will cause hard starting and leave gum deposits that will
clog the fuel system.
The length of time that fuel can be left in the fuel tank/
carburetor will vary depending upon storage conditions
–approximately 60 days after mixing.
You can avoid fuel deterioration problems by draining
the fuel tank and short starting the engine afterwards to
empty the carburetor.
