MAINTENANCE
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 the first time after 5 hours
running time.
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.
Place a suitable vessel to collect the oil in.
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.
Drive and gearbox
Ensure the wheels and wheel axles are clean and free from
leaves, grass, etc. It is also important to keep clean around
the drive gearbox.
Remove the protective cover by unscrewing the screws.
Clean the gearbox with a brush. Also check that the drive
belt and belt pulley are undamaged, for example, no
cracks.
Replacing and adjusting the V-belt
Remove the protective cover by unscrewing the screws.
Remove the hubcap on the front wheel by the gearbox,
prize carefully with a screwdriver. Unscrew the carriage
bolt and remove the wheel.
Remove the belt from the deck belt pulley. Check that the
deck belt pulleys move easily on the axle, spray with
penetrating oil between and behind the pulleys and
grease the axle.
Fit the new belt and make sure it fits correctly by the ball-
bearing before adjusting the belt.
