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.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
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 56 .
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. Take hold of the handlebars handle with your left hand. With your right hand then slowly push the lever (1 in Pict.3) on the right handle.
 Slowly press the lever up to about two thirds throttle, to start up the cutting disc and prevent the engine form turning off.
4. 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.

2.4.2.2 Putting the machine in motion

To put the machine in motion use lever (2 in Pict.3) 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.)!

2.4.3 Work with the machine

2.4.3.1 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 brushes in complete cutting width. We recommend to use the cutter partially (approximately 5-10 cm from the
edge of the plastic front cover) in the cut stand (as shown in Pict.5 from the user's point of view).
54 Multilingual manual and its Czech translation are part of the cutter..
55 Engine starting instructions are described in detail in engine user manual.
