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
49
.
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!

Before every use, check that the screws that fasten the work tool and those of the protection elements, covers,
and engine are properly tightened!
1. Start the engine
50
. 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. Grasp the left handlebar with your left hand. Use your right hand to move (lift) the right control lever ( 1 in Pict.2 ) into upper
position (
Pict.20
) until it is fully inserted into the calliper with cables.
3. Push the safety button on the calliper with cables in the direction of the arrow ( Pict.21 ).

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 ( Pict.22 ) 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 Selecting the wheel drive speed
The machine has two forward speeds. Slower (belt fitted according to Pict.24 ) is preferable for dense, wet, or high vegetation; faster
(V-belt is fitted as shown in Pict.23 ) is preferred for sparse, dry, or low laying vegetation.

Always adjust the drive speed to the type of vegetation or stop and wait for the work tool to process the
material before advancing!
