 Never attempt to lift the assembled machine by its front plastic cover. The cover will not support the machine’s weight.
1.4.1.1 Assembling procedure
Use the following procedure for assembling the machine: (It is advised 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 manual 18 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 starter 19 .
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 engine 20 . 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!
