7. REPAIRING MALFUNCTIONS AND DEFECTS<br />
Do not perform any repairs if you do not have the appropriate technical equipment and qualifications.<br />
The repairs described below may be performed by the user of the machine. Other repairs performed by<br />
the user that are not specified here will void the warranty. The manufacturer takes no responsibility for<br />
damages resulting from poorly performed unapproved repairs by the user.<br />
Malfunction, defect<br />
Remedy<br />
Remove grass that has accumulated on the underside of the mowing deck.<br />
The mowing deck<br />
mows unevenly<br />
When mowing,<br />
some vegetation<br />
remains uncut<br />
Make sure that the blades are sharp, are not deformed or damaged.<br />
Check that the blades are properly fastened.<br />
Check the blade shafts and the seating of the bearings. Replace them if they are damaged or<br />
overly worn.<br />
Check the bearing housings for damage. Based on your findings either repair or replace them.<br />
When mowing thick grass or grass that is too wet, an unmowed strip may remain. The travel<br />
speed should be adjusted to respect the mowing conditions by shifting into a suitable gear. The<br />
engine should not run with the throttle valve fully open.<br />
Check that the blades are sharp and undamaged. Replace the blades if necessary.<br />
Check the tension and condition of the V-belt of the mowing drive<br />
The mowing deck drive belt may be damaged, when it jumps out of the pulley while the machine<br />
is running. If it jumps out even after rechecking according to the following steps, it is necessary to<br />
replace the belt.<br />
Check the tension of the belt ( 6.3.7). If necessary adjust the tension.<br />
Check the belt guide pulleys.<br />
The mowing deck<br />
drive belt stops<br />
during operation<br />
Check the set mowing height, adjust if necessary.<br />
Check whether the movement of the belt is not prevented by a foreign object. If yes, remove the<br />
foreign object.<br />
Recheck all the belts. Buckled or cracked pulleys may cause problems. Replace if necessary.<br />
Check the inside surface of the pulley on the engine. If it is coarse or has cracks, it is necessary to<br />
replace the pulley.<br />
Check the parts of the tensioning mechanism for wear, replace the worn out parts if necessary.<br />
Change the travelling speed (e.g. slow down)<br />
Lift the mowing deck to a higher position<br />
If the grass is too tall or wet, the mowing deck drive belt may slip through. Check that the belt is<br />
not worn out. If it is, replace it.<br />
The mowing<br />
deck drive belt is<br />
slipping through<br />
Reduce the speed of the machine.<br />
Increase the mowing height.<br />
Check belt tension. If necessary adjust the tension.<br />
Check the tensioning mechanism (spring, pulley). Replace the spring if it is overstretched or<br />
damaged.<br />
Check the belt guide pulley.<br />
The mowing deck<br />
drive belt is being<br />
excessively worn<br />
out<br />
Check whether the movement of the belt is not prevented by a foreign object. If yes, remove the<br />
foreign object.<br />
Check the pulleys, if they are damaged, replace them.<br />
Check the set mowing height, adjust if necessary.<br />
Check the tension of the belt ( 6.3.7). If necessary adjust the tension.<br />
Check that the belt is not worn out or damaged. If it is, replace it. If it is loose, tension it.<br />
Check the tensioning mechanism spring. Replace the spring if it is cracked or damaged.<br />
The mowing deck<br />
cannot be started<br />
Check whether the movement of the belt is not prevented by a foreign object. If yes, remove the<br />
foreign object.<br />
Check the position of the mowing height lever. The safety switch prevents the activation of the<br />
electromagnetic clutch when in the transport position. Move the lever to the work position.<br />
Check the setting of the mowing deck switch<br />
