2.4.1 Assembling the machine
 As part of the pre-sale servicing, ask your dealer to unwrap the machine and give you a brief training on how to use it!
Places for holding the cutter while removing it from the box (see Pict.1 ): by the cutting disc in the front (4), by the machine frame tube in the
back (1).
 Never attempt to lift the assembled machine by its front plastic cover. The cover will not support the machine’s weight.
2.4.1.1 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), side and rear screens (7), screen holder (2) and parts of lower disk cover 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.3 - 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) Dismount the self-locking nuts 54 M5 (2 pieces) and washers, mounted by the manufacturer, off the frame and 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 washers
and self-locking nuts M5 back on the screws and tighten them.
5) According Pict.1 - put the rear (shorter) screen (7) on the shorter arm of the screen holder (2). Put the side (longer) screen (7) on the longer
arm of the screen holder (2). Put the clamp bands (2 pcs) through the holes in the screen holder and draw both bands to fix both screens.
6) According Pict.3 - unscrew the fastening bolt (5) so that the side gate (2) can be easily pushed into the frame opening. Tighten the
fastening bolt with your hand and check that the side gate does not fall out spontaneously.
7) According Pict.2 - the left (2) and right side cover (3) of the cutting disc to the middle part of the cover (1) using bolts M6x14 (2 pcs), nuts
M6 (4 pcs) and flat washers (4 pcs).
2.4.2 Putting into operation
 The cutter may be delivered without the engine operating fluids (according to various national rules)!
 First read the engine user manual 55 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.4 . 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 56 .
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.3) must be in the position turned off (they must not be pushed to the
handlebars)!
2.4.2.1 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 57 .
2. 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.)
3. Hold the left handlebars handle with your left hand. Move the right control lever (1 in Pict. 3 ) to the upper position until it slides in the stirrup
with wires (3 in Pict. 19 ).
4. Push the button of the safety lock (2 in Pict. 19 ).
5. Then slowly push the lever (1 in Pict. 3 ) on the right handle with your right hand. Hold the safety lock button until the stirrup starts to move
with the wires.
 Slowly press the lever up to about two thirds of its travel, to start up the cutting disc and prevent the engine form turning off.
6. 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 8 .
