MAINTENANCE
Carburettor
Adjusting the idle speed (T)
Check that the air filter is clean. When the idle speed is correct, the cutting attachment should not rotate. If adjustment is required, close (turn clockwise) the idle adjustment screw T, with the engine running, until the cutting attachment starts to rotate. Open (turn anticlockwise) the screw until the cutting attachment stops. The idle speed is correctly set when the engine runs smoothly in all positions, and there is a clear margin to the speed at which the cutting attachment starts to rotate.
Note: The machine should only be run for short periods at its highest speed.
WARNING! If the idle speed cannot be
! adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.
Muffler
CAUTION!
The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.
Procedures to be performed after every 100 hours of use
1Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon builup. Wipe away any carbon buildup on the muffler exhaust vent and cylinder exhaust vent at the same time.
2Tighten all screws, bolts and fittings.
3Check to see if any oil or grease has worked its way in between the clutch lining and drum, and if it has, wipe it away using
CAUTION! Never use a machine with a defective muffler.
Cooling system
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of:
1Cooling fins on the cylinder.
2Air intake / cooling vent (back)
Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
