Replacing the blade
WARNING
The cutting blade bar must always be replaced by an authorised workshop. A wrongly assembled cutting blade
coupling or a blade screw that is tightened too tightly or too loosely can allow the cutting blade bar to become loose
and cause severe injuries.
– Only use original blades for replacement purposes.
– Blades must be indelibly marked with name and/or trademark of the manufacturer or supplier and with the parts number.
Servicing the front wheels
Oil the bearings of the wheels once a year or every 50 operating hours.
– Loosen the hexagon head nuts using a socket wrench and remove the wheels.
– After oiling the bearings, push the wheels on and tighten them again so that they still turn easily but without any play.
Servicing the rear wheel drive (Illustration R )
Grease the bearings of the wheels once a year or every 50 hours of operation.
– Remove the drive wheels from the wheel axle after loosening of the nut.
– Remove dirt and any grease from the wheel cover, from the free wheel pinion on the gear shaft and the drive pinion on
the inside of the wheel.
NOTE
Do not remove the free wheel pinion from the gear shaft!
– Grease the pinion pair (free wheel pinion and drive pinion in the wheel) with the roller bearing grease "KAJO LZR 2
lubricating grease", so that the toothed intermediate spaces are completely filled.
– When pushing on the drive wheel make sure that the pinions engage; it may be necessary to turn the wheel on the axle
slightly.
Servicing the drive
– It is absolutely essential that the Bowden cable runs easily for switching on and off, so that the control drive works
perfectly.
– The Bowden traction mechanism has been set ready for operation at the works and requires no adjustment.
Changing the brake clutch and the drive V-belt
The brake clutch and the drive V-belt must be replaced by a specialist workshop.
Adjustment of the blade brake Bowden cable
The blade-brake throttle cable must be adjusted at least once per mowing season by an authorised workshop.
Correct adjustment of the throttle cable guarantees the most important safety functions of the control bar. As soon as the
control bar is released, the cutter bar must come to a standstill within three seconds.
