MAINTENANCE
Clean the filter by knocking the filter against a flat surface. Never use solvent with petroleum, for example, kerosene, or compressed air to clean the filter.
When reassembling, make sure that the filter completely seals against the filter holder.
Spark plug
WARNING! The muffler gets very hot in use
!and remains so for a short time afterwards. Do not touch the muffler if it is hot!
If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.76 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.
CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.
Muffler
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.
Regularly check that the muffler is securely attached to the machine.
Never use a machine that has a faulty muffler.
Cutter
WARNING! Always wear
!when repairing the cutting attachment. The blades are very sharp and can easily cause cuts.
It is important to have a sharp and correctly balanced cutter. Loosen the bolt holding the cutter and leave the cutter at a service workshop at least once a year for grinding and balancing. An appropriate time to do this is after the mowing season has finished.
If the cutter or cutter bracket need to be changed you must replace the cutter bolt, washer and cup spring at the same time.
The bolt should be tightened with a torque of
If the cutter hits foreign objects such as stones, roots or the like the cutter will slip against the cutter bracket. This may mean that the contact surface of the cutter bracket appears slightly worn, which is completely normal. This is a safety device, which reduces the risk of the engine shaft becoming bent.
Changing the oil
The engine oil should be changed each year and every 25 working hours.
When changing the oil proceed as follows::
•Empty the fuel tank by running the machine until the tank is empty.
•Disconnect the HT lead from the spark plug.
•Unscrew the oil filler cap.
