Use the following procedure for assembling the machine: (It is ad ised to assemble the machine with a second person’s assistance)
1) According Pict.1 - take the disc cover (3), bag (6), screen holder (7), both parts of the side screen (2), left and right disk cover (8) out of the
box. Pick the machine up by its lift points in front (4) and back (1) and take it out of the box.
2) According Pict.5 - dismount the bolted connection (3) on both sides of the frame, take off the handlebars, turn them around and put them on
the frame as shown in the picture (choose one of the 3 holes in the handlebars to set their height). Re-tighten the bolted connection firmly with
your hand. Control lever cables must not be crossed - this shortens their lifetime!
3) Take the draw bands out of the bag and tighten brake cables to the handlebars where the upper bending of the handlebars tube ends. Two
pieces of draw bands are sufficient for cable tightening.
4) According Pict.2 and Pict.3 – mount the left and right covers of the cutting disk by the help of M6x14 bolts (2 pcs), M6 nuts (4 pcs) and
washers (4 pcs).
5) According Pict.4 – set the disc cover on the machine so that the holes fit in the screws in the frame, and the narrowed part of the cover is
pushed in under the engine plate. Put the handle on the cover. Screw the handle to the disk cover in its upper part with two M6x16 bolts with
square end, with washer and self-locking nuts M6. Put the washers and M5 nuts on the screws in the frame and tighten them.
6) Put the rear (shorter, with cut-out) screen part and the side (longer) screen part on the screen holder. Put the clamp bands (2 pcs, they are in the
bag with parts) through the holes in the screen holder and draw both bands to fix both screen parts.
7) According Pict.5 - unscrew the fastening bolt (5) so that the side screen (2) can be easily pushed into the frame opening. Tighten the fastening
bolt and check that the side screen does not fall out spontaneously.
1.4.2 Putting into operation
The cutter may be delivered without the engine operating fluids (according to various national rules)!
First read the engine user manual18 carefully! This way you may avoid possible damage.
1. Check the engine oil level; fill the engine with prescribed type and amount of oil if necessary. Fill the tank with prescribed amount and type of
petrol.
2. Shift the accelerator lever into ‘CHOKE’ position. The accelerator lever positions are described in picture Pict.6. All four described main
positions are locked by a simple stamp-projection system in the lever body.
3. Start the engine by pulling the rope of the recoil starter19.
4. First let the new or cold engine run for about 30 sec with a choke (accelerator lever in ‘CHOKE’ position) and then shift the accelerator lever
into ‘MAX’ position. Let the engine run in this position for about 30 sec.
Do not go away from the machine!
When starting the engine both control levers (1 and 2 in Pict.5) must be in the position turned off (they must not be pushed to the
handlebars)!
1.4.2.1 Starting up the cutting disc
Make sure that all persons animals and children are at a safe distance from the machine! If they are not do not continue in your
activity!
1. Start the engine20. Use the accelerator lever to set the maximum engine speed. In case the engine is cold, warm it up at maximum speed for about 1
minute.
2. Hold the left handlebars handle with your left hand. Move the right control lever (18 in. Pict.5) to the upper position until it slides in the stirrup
with wires and with the safety lock (17 in Pict.5).
3. Push the button of the safety lock (17 in Pict.5) on the stirrup. Hold the button until the control lever starts to move with stirrup with the wires.
4. Then push the control lever on the right handle with a smooth slow movement of your right hand.
Slowly press the lever up to about two thirds throttle to start up the cutting disc and prevent the engine form turning off.
5. After starting up the cutting disc, press the lever to the handle and hold firmly.
The cutting disc start-up is accompanied by V-belt creeping and its side effects (chattering whistling). These effects usually
disappear when the V-belt is run-in.
Note: During the first starts of the cutting disc, a new or cold engine might stall. This tendency disappears after warming up the engine. In case the
cutting disc drive cannot be runned up, check if there is a defect according to Table 7.
1.4.2.2 Putting the machine in motion
To put the machine in motion use lever (2 in Pict.5) on the left handle. Press the lever all the way to the handle, and the machine moves ahead
immediately. Adjust the speed of your walk to machine speed as soon as you press the lever and the machine moves.
The wheel drive has a belt clutch; you can press the lever slowly and the machine starts off fluently, not with a jump.
Always press the clutch lever all the way down to the handlebars. If the lever is not pressed properly it causes damage to the V-
belt.
The wheel drive clutch lever does not adjust travelling speed!
Never reverse with the wheel drive clutch pressed!

1.4.2.3 Machine stopping
If you wish to stop the machine, release the left handlebar lever. The machine stops moving, but the cutting disk spins. The cutting disc drive is turned
off by releasing the right handlebar lever. The cutting disc is stopped by an automatic brake. Shift the accelerator lever into 'MIN’ or ‘STOP’ position.
Always switch off the engine and wait for the cutting disk to stop before starting any activity near the machine! Always switch the
engine off before leaving the machine!
Never leave the engine running at the maximum engine speed for a long time or running idle while the clutch of the cutting blade
drive and wheel drive are turned off! The machine drive parts could be damaged (V-belt belt pulley clutch pulley etc.)!
1.4.2.4 Travel speed selection
The machine drive is equipped with two speeds. The slower one (turtle) for dense, wet or high stands, the faster one (hare) for sparse, dry or low
stands.
Always adjust the travel speed to the stand type!
The speed change is made by moving the V-belt on the belt pulleys between the gearbox and the wheel axle (see Pict. 17 and 18). There is a sticker
with a picture showing the positions of the V-belt in the belt pulleys on the gearbox and the axle on the upper gearbox cover (see Pict. 16).
Always change the speeds when the engine is off and the accelerator lever is in the STOP position!
1. Dismount the plastic nut and the upper gearbox cover. Put the lower gearbox cover foot out of the bolt in the frame and leave it lying on a pad.
2. Put the V-belt completely out of the gearbox pulley to the right into the groove in the frame between the belt pulley and the machine frame tube.
3. Move the V-belt forward for approx. 1,5 cm and then move it into the V-belt groove in the belt pulley on the wheel axle, corresponding to the
selected speed. Check with your sight and hand whether the V-belt is correctly seated in the groove of the selected belt pulley.
4. Put the V-belt into the gearbox pulley groove, corresponding to the selected speed. Check with your sight whether the V-belt is seated straight in
correct belt pulleys corresponding to the selected speed (see Pict. 17 and 18). The V-belt can’t be crossed!
5. Mount both covers back.
1.4.3 Work with the machine
1.4.3.1 Cutting width
Always adjust the cutting width to the stand density!
It is not recommended to use the maximum cutting width (Table 3) given by the disc construction. In a terrain, the user cannot operate the cutter
straight, and precisely enough to cut the stand in complete cutting width. We recommend to lead the cutter in the cut stand approximately 5-10 cm from
the edge of the plastic front cover (as shown in Pict.7 from the user’s point of view).
1.4.3.2 Methods of stand cutting
Remove any solid parts form the stand before cutting (such as stones wires loose construction leftovers etc.) as these could be thrown
away or damage the machine. If these cannot be removed avoid them.
It is necessary to keep the lower disc sliding across the land without bouncing off when cutting in uneven terrain. Disc bouncing causes low quality
stand cutting and uneven stubble.
Let the engine and cutting disc spin in their maximum rpm, and start moving against the stand you wish to cut. The cutting disc throws cut stand onto
the right side, where it is windrowed by the side screen.
➢Always keep the uncut stand on the left side form the machine when cutting (Pict.7).
➢When cutting on slopes it is best to move along the slope contour line. Keep the safe climbing ability (Table 3)!
In case the cut stand is too dense, inter grown, rotten, or flattened, it is necessary to reduce the machine cutting width, so that the cutting disc rpm
would not be too low, and thus causing low cutting quality.
1.4.3.2.1 Cutting problems
Be especially careful when lifting and reversing the machine!
Always turn the engine off when cleaning the space under the top cover!
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 travel 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.

1.5 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.
1.5.1 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.
1.5.1.1 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)
➢MINimum21 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 inner tube defect.
Seek authorised service in case you lack appropriate manual skills.
1.5.2 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. icycle oil). The
gearbox is filled with sufficient amount of oil during manufacturing and it does not require filling during the whole machine life.
1.5.2.1 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.
1.5.2.2 Lu ricating 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.
