2.5.1.2 Procedure for removing the driving unit

Do not remove the driving unit from the gearbox while the engine is running!
Details on Pict. 5.
1. Loosen the tightening crank 2 on the gearbox console.
2. Disconnect the quick-operating clamps 3 by taking the spring eye from below by hand and release it by pulling upwards.
3. Remove the latch of the quick-operating clamp from the notch in the rivet 4 and tilt it away so that it is not in the way when taking the
driving unit out of the gearbox.
4. Pull the driving unit out of the gearbox (or adapter by smooth continuous pull, applied parallel to the axis of the engine crankshaft.

Be careful when connecting and disconnecting the quick-operating clamps! Your fingers can be injured! The
springs have a great pull and considerable force is required for connection or disconnection.

Never put the driving unit on easily ignitable materials. The high operating temperatures could cause a fire!

Never put the driving unit on dirt, sand and similar materials that could contaminate the clutch linings or the flange connecting
surface.
2.6 Controls
2.6.1 Accelerator lever
Engagement of centrifugal clutch and the transfer of engine output depends on the engine revolutions. This is why the control of engine
with this clutch requires a different technique than the control of engine with for example multi-plate clutch:

Always use the MAX imum engine revolutions so that clutch slippage does not occur and hence damage to the clutch.

Increase the engine revolutions fast so that the engine working speed is reached in the shortest possible time and unwished-for
clutch slippage does not occur. When the engine speed is reached fast the centrifugal clutch engages smoothly.

Particularly with using the driving unit on small one-axle tractors with one-axle trailers ensure using correct gears at full use of
the trailer load capacity, appropriate to engine load and the nature of terrain. Engage lower gears at which the engine power is
utilized better and the clutch does not suffer due to low revolutions of the engine.

When driving downhill make use of engine braking. Shift the freewheel hub control element to position LOCKING to have the
wheels in immanently engaged. Reduce the speed to about
2/3 MAX imum engine revolutions. The clutch still fully transmits
the revolutions and the motor helps braking the assembly.

In the new clutch lining some accompanying phenomena of clutch slippage in the driven clutch plate may occur – such as
“metallic” whistling, rattling etc.. The phenomena are not a reason for raising a complaint about the clutch or about the whole
machine since they disappear after the clutch lining has been run-in.
The individual positions of the lever are automatically locked in the lever body, during the trailing stage to a given position the control
lever readily snaps in.

This position is not connected;
the motor is switched off by the
safety switch.
Engine is idling and clutch is not
engaged. engage
Used for example when
changing gears.
Engine is running in maximum
revolutions and clutch is fully
engaged; working position.
Used only when starting cold
engine.

2.6.2 Safety switch

Before proceeding with work with any operating machines of the system, check the function of the engine safety
shutdown with a switch on the left handlebar handgrip of the engine unit.
Ignition safety switch BVA-96 ensures the engine ignition switch-off and hence the engine stoppage immediately after the operator has
left its working position either in a critical situation or in shut down of the machine.
Details on Pict. 7.
35
On XP-200 engines this position is not connected or marked on the lever; the accelerator lever will shift to this position, but the movement of the control cable does not cause any
engine response.
