Checking the fuel pump's air filter
Check regularly that the fuel pump's air filter is free from dirt.
•
Remove the screws and open the pump, no hoses need
be removed.
The filter can when necessary be cleaned with a brush.
•
Replace the pump on the console.
Ignition system
The engine is equipped with an electronic ignition system.
Only the spark plug requires maintenance.
For recommended spark plug, see Technical data.
IMPORTANT INFORMATION Fitting the wrong spark plug
type can damage the engine.
Replacing the spark plug
1 Remove the ignition cable shoe and clean around the
spark plug.
2 Remove the spark plug with a 5/8" (16 mm) spark plug
socket wrench.
3 Check the spark plug. Replace the spark plug if the
electrodes are burned or if the insulation is cracked or
damaged. Clean the spark plug with a steel brush if it is to
be reused.
4 Measure the electrode gap with a gapping tool. The gap
should be 0.75 mm/0.030". Adjust as necessary by
bending the side electrode.
5 Reinsert the spark plug, turning by hand to avoid
damaging the threads.
IMPORTANT INFORMATION
Inadequately tightened spark plugs can cause overheating
and damage the engine. Tightening the spark plug too
much can damage the threads in the cylinder head.
6 Tighten the spark plug, once it touches the seating, with
the spark plug spanner.
Tighten the spark plug so that the washer is compressed.
A used spark plug should be turned 1/8 of a turn from the
seated position. A new spark plug should be turned a 1/4
turn from the seated position.
7 Replace the ignition cable shoe.
IMPORTANT INFORMATION
Do not turn over the engine if the spark plug or ignition cable
has been removed.

Maintenance
Check the safety system
The machine is equipped with a safety system that prevents
starting or driving under the following conditions.
The engine must only be possible to start when the following
conditions are met:
•
The cutting unit is in raised position.
•
The parking brake is applied.
The engine must stop under any of the following conditions:
•
The cutting deck is lowered and the driver rises from the
seat.
•
The cutting deck is in its raised position, the parking brake
is not applied and the driver rises from the seat.
Check daily to ensure that the safety system works by
attempting to start the engine when one of the conditions
above is not met. Change the conditions and try again.
Main fuse
The main fuse is placed in a detachable holder under the
battery case's cover, in front of the battery.
Type: Flat pin, 15 A.
Do not use any other type of fuse when replacing.
A blown fuse is indicated by a burnt connector. Pull the fuse
from the holder when replacing.
The fuse is there to protect the electrical system. If it blows
again shortly after replacement, it is due to a short circuit,
which must be fixed before the machine can be put into
operation again.
Checking the tyre pressure
The tyre pressure should be 60 kPa (0.6 bar / 9 PSI) all round.
To improve driving the pressure on the rear tyres can be
reduced to 40 kPa (0.4 bar/5.6 PSI).
The maximum tyre pressure is 100 kPa (1,0 bar/14 PSI).
IMPORTANT INFORMATION
Different tyre pressures on the front tyres will result in the
blades cutting the grass at different heights.
