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
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.3. 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
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.2) 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 (18 in. Pict.2) to the upper position until it slides in the stirrup
with wires and with the safety lock (17 in Pict.2).
4. Push the button of the safety lock (17 in Pict.2) on the stirrup. Hold the button until the control lever starts to move with stirrup with the wires.
5. 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.
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.
2.4.2.2

Putting the machine in motion

To put the machine in motion use lever (2 in Pict.2) 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!
2.4.2.3

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.)!
2.4.2.4

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. 12, 13, 14 and 16). 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. 15).
 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. 14 and 16). The V-belt can't be crossed!
5. Mount both covers back.
