 Check that the blades are not bent or twisted, also check that they are balanced. If they are
deformed, replace them.
 Check that the belt does not have burned areas or irregularities, which could cause the vibrations.
If the belt is damaged, replace it.
 Check that the blades are not worn out or damaged. Replace them if necessary.
 Check that the electromagnetic clutch switches on properly. If the clutch is not working properly
have it replaced or repaired at an authorised service centre.
 Check the inside surface of the pulley on the engine. If it is coarse or has cracks, it is necessary
to replace the pulley.
 Check whether grass has accumulated on the underside of the mowing deck. It is necessary to
remove this grass.
 Check whether the defect is not in the engine mount. Tighten bolts or replace as necessary.
 Check the belt tension (
 Check the tension of the travel drive belt (
 Check whether the belt is damaged or worn out.
 Check whether the movement of the clutch mechanism is blocked by a foreign object. If yes,
remove the foreign object.
 Check the engine belt pulley or transmission belt pulley for damage. Replace if necessary.
 Check the tension of the travel drive belt (
necessary adjust the tension of the belt. If the brake is not in proper working order, have it
adjusted at an authorised service centre.
 Check the tension of the travel drive belt (
 Check the route of the belt. Adjust if necessary.
 Check whether the pulleys are damage. Replace them if necessary.
 Check the gap of the travel clutch mechanism. Deviations may result in the clutch bearing holder
being bent out of shape. Replace it if necessary.
 Check the tension of the travel drive belt (
 Check the belt pulley of the engine and transmission with respect to cut off or damaged grooves.
Replace it if necessary.
 Check whether any pulleys are damaged or deformed. Replace them if necessary.
 Check whether the belt has any burned spaces or other irregularities. Replace it if necessary.
 Check the tension of the travel drive belt (
 Check that the mowing blades are balanced. Balance or replace them if necessary.
 Check that the space between the pinion and the segment is not too large. If yes, adjust the
cogged segment. Check for wear on the ball and socket joints. Replace the joints if necessary.
 Check that there is petrol in the petrol tank.
 Check that the prescribed procedure for starting the engine was followed (
 Check the fuse. Replace if necessary.
 Check whether the voltage on the battery terminals is 12 V. On a new machine check whether
the battery was activated and charged. On new machines replace the spark plug and check that
there is not oil accumulated on the cylinder due to incorrect handling.
 Check that all wire connections are in order and that the electrical system switches work.
 Check the engine again exactly according to the instructions in the User's manual of the engine
manufacturer. Have the electrical system checked at a specialised workshop.
 Check that the prescribed procedure for starting the engine was followed (
the petrol in the petrol tank is clean.
 Check that the fuel filter is not clogged.
 Check whether the fuel tap is open (applies only to machines with a BS15, HP engine).
 Make sure that the throttle lever is in the position "CHOKE".
 Check the engine again exactly according to the instructions in the User's manual of the engine
manufacturer. Have the cabling and switches checked at a specialised workshop.
 Check that the by-pass lever is in position "0".
 Check the condition of the belts and the tensioning pulleys If the problem persists, immediately
contact an authorised service centre.
 Use the emergency travel system and drive the machine to a location from which it can be
transported to a service centre (
