Maintenance
Checking the engine’s cooling air intake
Clean the air intake grille in the engine cover behind the driver’s seat.
Open the engine cover.
Check that the cooling intake is free from leaves, grass and dirt.
Check the air duct, located on the inside of the engine cover, ensure it is clean and does not rub against the cooling air intake.
A blocked cooling intake will interfere with the cooling of the engine, which can damage the engine.
WARNING! The cooling air intake rotates
!when the engine is running. Mind your fingers.
Checking and adjustment of the cutting unit’s ground pressure
To achieve the best cutting results the cutting unit should follow the underlying surface without pressing too hard against it. Pressure is adjusted using a screw and spring on each side of the Rider.
1Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.
2Place a set of bathroom scales under the cutting unit’s frame (front edge) so that it rests on the scales. If necessary a block can be placed between the frame and scales so that the support wheels do not bear any weight.
3Adjust the cutting unit’s ground pressure by screwing the adjuster screws, which are located behind the front wheels on both sides, in or out. The ground pressure should be between 12 and 15 kg and the springs evenly tensioned.
Checking the cutting unit’s parallelism
Check the cutting unit’s parallelism as follows:
1Check the air pressure in the tyres 60 kPa/0.6 kp/cm2/8.5 PSI.
2Place the machine on a flat surface.
3Measure the distance between the ground and cutting unit’s edge at the front of the cover.
The cutting unit should have a slight slant, with the rear edge
Adjusting the parallelism of the cutting unit
1Check the air pressure in the tyres 60 kPa/0.6 kp/cm2/8.5 PSI.
2Remove the front cover.
