MAINTENANCE
Cutter
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 45-60 Nm when
you fit the cutter again. See instructions under the heading
Assembly.
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::
• Disconnect the HT lead from the spark plug.
• Empty the fuel tank
• Close the fuel tap.
• Unscrew the oil filler cap.
• Drain the oil by tipping the engine so that the oil runs out
through the filler pipe.
• Ask where you can dispose of surplus engine oil at your
local petrol station.
• Fill with new engine oil of a good quality. See the Technical
data section.
• Check the oil level with the dipstick on the oil filler cap. The
oil filler cap must be completely screwed down to give a
correct picture of the oil level.
If the oil level is low, fill using engine oil up to the upper
level on the dipstick.
• Screw on the oil filler cap.
Lubrication of the cutting height
adjustment
The mechanical parts of the cutting height system should be
lubricated regularly (once a week). Lubricate the cutting
height system with a few drops of oil.
!
WARNING! Always wear heavy-duty gloves
when repairing the cutting attachment. The
blades are very sharp and can easily cause
cuts.
