Cutter

WARNING! Always wear heavy-duty gloves
!
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 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::
• Empty the fuel tank by running the machine until the tank
is empty.
• Disconnect the HT lead from the spark plug.
• Unscrew the bolt holding the cutter.

MAINTENANCE
• Loosen the bolts holding the protective hood and then lift
off the hood.
• Unscrew the oil filler cap.
• The oil can be drained from the underside by loosening
the oil plug. Do not forget to refit the oil plug before filling
with oil again.
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.
