Maintenance, Servicing And Storage; Travelling Wheels; Tyre Pressure; Machine Lubrication - Vari BDR-620D Bedienungsanleitung

 Always tip the machine backwards on its handlebars only. Always be especially careful when moving in the space under a lifted
machine. Secure the cutter from spontaneous movement!
 Always be especially careful when cleaning the space under the top cover. The cutting blades are sharp. Use work gloves, or other
convenient objects, e.g. a piece of branch, for cleaning the machine.
 Before continuing any activity on the machine or its surroundings, always wait until the cutting disc stops.
1. The cutting disc and the engine rpm are both slowing down, but the engine does not stall.
➢ Stop the machine immediately, reverse slightly while lifting the front of the machine a bit (by pressing the handlebars down). The
space under the top cover partially cleans itself from extensive amounts of grass mass. Start moving against the stand again.
2. Cutting disk stopped spinning, the engine staled.
➢ Release both handlebars levers and lift the cutter by pressing the handlebars. Move the cutter slightly backwards. Clean the space
under the top cover, and spread the cut grass across the surface. Start the engine, turn the cutting disc drive on, and start moving against
the stand again.
3. The cut brushes keeps catching on the side screen (because the stand is too thick).
➢ Stop the cutter and turn the engine off. Dismount the side screen and put it in a safe place, out of the cut area, so that it cannot be
stolen.

Maintenance, servicing and storage


The weight of the cutter requires two persons for carrying out its maintenance and adjustment.
In order to be happy with our product in the long-term, it is necessary to give it adequate maintenance and servicing care. Regular maintenance
reduces deterioration and ensures proper functioning.
Follow all instructions concerning maintenance and adjustment schedule. It is recommended that you keep a record of the amount of its working time
and conditions (for service needs). It is recommended to let one of our authorised service centres take care of the after-season maintenance, as well as
regular maintenance if you are not sure about your technical skills.
 Check the nuts tightening the upper disc blades and nuts tightening the lower disc to the flange before each cutter use.
2.5.1

Travelling wheels

Travelling wheels create an important part of the cutter. Wheels carry the whole weight of the cutter, transfer engine power, and push the cutter into
mesh. Wheels have tyre tubes, which can be easily removed, in case of a defect, due to split rims connected with several bolts.
2.5.1.1

Tyre pressure

Tyre pressure has to be controlled in order to secure proper functioning and long life of the wheels, especially the tyres. Check the pressure before you
start using the cutter. Fill the pressure to MAX before putting the cutter out of service for a longer period of time. Keep equal pressure in right and left
wheels - it helps the cutter to keep a straight track.

Do not exceed the maximum tyre pressure – you risk a tyre explosion!
➢ MAXimum (recommended) tyre pressure: 23 PSI (160 kPa or 1,6 bar or 1,57 atm or 0,16 MPa)
➢ MINimum 59 allowed tyre pressure: 18 PSI (124,1 kPa or 1,24 bar or 1,22 atm or 0,124 MPa)
In case of permanent tyre pressure release, check and repair possible tyre defect.
 Seek authorised service in case you lack appropriate manual skills.
2.5.2

Machine lubrication


Follow basic hygienic rules and environmental laws when working with lubricants.
 Seek authorised service in case you lack appropriate manual skills.
Smooth and easy movement of all mechanical parts requires adequate lubrication. Several drops of oil are usually sufficient (e.g. Bicycle oil). The
gearbox is filled with sufficient amount of oil during manufacturing and it does not require filling during the whole machine life.
2.5.2.1

Engine oil exchange

Follow the engine user manual instructions. If you use the cutter in a dusty environment, shorten the exchange period by half. When pouring the oil
out of the engine tilt the cutter on its filler and oil dipstick side or dismantle the whole engine.
 Seek authorised service in case you lack appropriate manual skills.
2.5.2.2

Lubricating points

There is no need to dismount any covers from the machine when lubricating the cables on the handlebars. You can reach other lubricating points after
dismounting the plastic covers. You can use any kind of engine, transmission or spray oil. Any kind of lubricant grease for water pumps is fully sufficient.
For its application, however, it is usually necessary to dismantle the appropriate sliding sealing.
Note: When using graphite grease, the seasonal lubrication intervals can be extended up to 25 hours.
59 Tyre pressure lower than minimum damages the tyre construction and shortens its life.
