2.5.3 Work blades service and exchange
Seek authorised service in case you lack appropriate manual skills.
If the work blades are deteriorated or damaged, thus causing mower vibrations, it is necessary to renew or exchange the blades
Note: The manufacturer bears no responsibility for damages caused by/on the cutter, in case of a botched-up blades repair, or when reproduction parts
are used. A sign identifying the manufacturer is imprinted in the blade, and it is used as a proof of a genuine part.
The cutter must be secured from unexpected spontaneous movement, and stand on a safe pad, to allow adequate access to the blade.
Pay special attention when dismounting the blades. The blade edges are sharp. Protect your hands with work gloves.
The engine must be off, and the end of the spark plug cable must be taken off!
Proceedings:
1)
Hold the upper disc so that it does not spin, and use tubular wrench n.16 to dismount the bolted connection of the blade. First unscrew the nut,
then the bolt.
2)
Take the blade and its parts out of the cutting disc. Align the blades and sharpen them. The blade slope should hold 30º angle with the bottom
blade level.
3)
Check all blade parts for visible marks of damage. In case of damage, exchange the part with a new one.
4)
Tighten the blade bedding back. Tighten the bolt firmly
. Secure the bolt from loosening with a nut.
If some of the blades are bended or deteriorated you must exchange all cutting disc blades!
2.5.4 Belt transmissions
The cutter is equipped with belts that do not require special care. It is only necessary to control them regularly, and exchange them should you see
cracks or breaks on their surface. It is necessary to check on the tightening pulleys setting after the first 5 hours of operation, as the belt is being run-in. It
is necessary to check the tightening pulleys function during the initial run, in order to prevent belt damage caused by its insufficient tension after its
extension. It is also important to check the function of the automatic disc brake during the initial run.
2.5.4.1.1
V-belt exchange
Replace the V-belt with a new one
every time you see cracks or breaks in its surface, or when it is so deteriorated that it cannot be tightened with the
tightening pulleys. Exact instructions for belt exchange are not included here, as their contents exceed the limitations of this manual. Follow the belt track
around all manual elements (see Fig. 13)!
Seek authorised service in case you lack appropriate manual skills.
The correct belt transmission function is easy to check:
a)
A machine with the wheel drive on must be able to deal with a 10 cm terrain obstacle – e.g. a kerb.
b)
When the disc drive clutch is pressed, the cutting discs start spinning. The belt already starts to grip (the disc starts spinning) in just
1/3 step of the disc drive clutch lever.
If you had problems with at least one of these, the tightening pulleys need adjustment.
51
The blades have both-side razor-edges – they can be turned, if need be. Blade must be undamaged at any time.
52
Insufficient tightening of bolt leads in majority cases to damage of the hardened washer around which the blade rotates.
53
Exclusively use V-belts recommended by the manufacturer. If belts of other manufacturers are used, correct function of transmissions cannot be guaranteed.
