7.7 BULB REPLACEMENT
Lift off the bonnet.
The bulbs of K20, 12V / 10W type are inserted in a bayonet socket.
10 W / 12V type halogen light bulbs are mounted inside M Light type headlights HLRG-510F with
a diameter of 51 mm (socket GU5.3). If you need to change the bulb, use light bulb type M light
HSS-510, or another type from a different manufacture but with the same parameters and rating.
20 W / 12V type halogen light bulbs are mounted inside M Light type headlights HLRG-35/520F
with a diameter of 35 mm (socket GU4). If you need to change the bulb, use light bulb type M light
HSS-520, or another type from a different manufacture but with the same parameters and rating.
To remove the light bulb, flip open three iron sheet flaps, place the bulb in the socket and close the
flaps back.
7.8 FUSE REPLACEMENT
Lift the front bonnet and remove the protective cover. Remove the fuse and insert a new one withthe
same value as the original fuse, i.e. 15A or 20 A. If it is not possible to start the engine or put the
mowing mechanism into operation even after the fuse has been replaced, contact anauthorized
service.
7.9 MACHINE JACK UP
If you want to jack up the mowing machine, use a jack and supports.
When jacking up, proceed as follows:
•
Place the jack under the gearbox on the rear axle and jack up the rear part of the machine.
• Put two supports under both ends of the axle inside the side of the rear wheels.
• Jack up the front part of the machine and put two supports under the ends of both front wheel pintles.
• Never try to tilt the machine on the carburettor side. Motor oil may get inside the air filter!
7.10 REPLACEMENT OF MOWING MECHANISM BLADES
The mowing blades must be sharp, statically balanced and straight. These conditions are important for the evenness of the height of mowing and the qual-
ity of the cut. A blunt cutting edge worsens both the quality of mowing and the result of mowed grass collection.
Replace the blades as follows:
•
Tilt the machine toward the right side and support it. If necessary, dismantle the mowing mechanism.
• Unscrew both blades, clean them and sharpen them. Check the static balance of the blades (see the figure above).
• When reassembling, make sure the bendings of the blades are pointing upwards into the cassing of the mowing mechanism.
Do not confuse the left blade with the right one. The right blade is provided with the screw that has a left-hand thread.
• Check the condition of the shear pins which serve as the protection of the mowing mechanism against damage.
If the shear pins are damaged replace them immediately.
• Tighten the fixing screws of blades thoroughly with the specified tightening torque of 30
앐
3 Nm. This tightening torque is attained in the moment
when the spring washer under the blade fixing screw is fully pressed and the screw is not further tightened as of this moment.
CAUTION !!
When the blades hit a solid obstacle, stop the engine immediately and check the blades! The shear pins may be damaged or cut.
Replace the cut pins with new ones provided with the machine equipment.
Also check if the fixing screws of the blades are tightened with the tightening torque as specified.
