Filling with fuel

Safety information!

For explanation of symbols, see the table on page 3

–  Only fill the tank with fresh and clean unleaded standard petrol.

Fuel with up to 10% ethanol is acceptable.

–  Unscrew the tank cap.
–  Fill tank with fuel using a funnel up to max. lower edge of the filling nozzle.
–  Replace tank cap and screw tight.

10  STARTING THE ENGINE (FIGURE  S2  +  D  +  E  +  Q2 )

Safety information!

For explanation of symbols, see the table

on page 3

Before starting the engine make sure that the cutter shaft/the device is in the
surface cutting position  Z2 .

Start the engine from the right-hand side of the scarifier. Always place the scarifier on
a level area which is not covered with high grass (if the grass is too high it will block the

cutter shaft start-up and make starting the scarifier more difficult). When the engine is
started, the machine must not be tilted on end, if necessary it must be tilted by pressing

the guide bar down so that the cutting tool is pointing in the direction away from the
user, but only as far as absolutely necessary. As long as the device has not been

lowered to the ground again, both of your hands must be on the top part of the bar.

CAUTION

Hold the starter cable handle firmly when starting. The handle may otherwise
slip out of your hand. Risk of injury!

–  Open the fuel tap (2)

S2

.

–  If the engine is

cold

, push the choke lever (3) on the engine to the “Choke”

position  .

–  Move the throttle control lever (4) backwards to position “Hare”. During engine

operation, the throttle control lever should remain in “Hare” position.

–  To start the engine, pull the safety grip (5) on the top guide bar. During

operation, the safety grip must remain held in this position

D

 .

–  Slowly pull the starter cable (7) until resistance is felt, then pull it out rapidly,

– the engine begins to run, slowly recoil the cable

E

 .

–  Under certain circumstances the starting process must be repeated.
–  After the engine has warmed up, push the choke lever (3) forwards into

operating position

Q2

 .

–  In an

operationally hot

engine, push the choke lever (3) on the engine

forwards into operating position. Start the engine as described above.

–  If the engine does not start running, then proceed as when starting

a cold engine.

11  SWITCHING OFF THE ENGINE (FIGURE  F  +  Y2 )

–  Release the safety control bar (1)

F

 . The engine switches off and the cutting

tool comes to standstill. Attention! The cutting tool runs for a while!

–  Close the fuel tap (2)

Y2

 .

12  EMERGENCY STOPPING

Release the safety control bar.

–  The cutting tool will stop. Attention! The cutting tool runs for a while!
–  The engine will stop.

ATTENTION

Before every scarifying job, make sure that the engine stop safety control bar
is working perfectly:
–  When the safety grip is released, the engine must switch off and the

cutting tool must come to a standstill (Caution! The cutting tool runs

for a while!).

If this is not the case, please consult your nearest authorised workshop.

13  ADJUSTING THE SCARIFYING DEPTH

Safety information!

For explanation of symbols, see the table on page 3

The scarifying depth must only be adjusted with the engine switched off!

To work with the scarifier, the scarifier lever is pushed forward into the “Scarify”
position

T2

 . This lowers the device with cutter shaft and the blades penetrate the turf.

The working depth depends on the blade wear, and must also be set taking into

account the relevant grass and ground conditions.
Always check and adjust the scarifying depth on a level area of lawn.
With the cutter shaft lowered, the blade should just be in contact with the turf. A working
depth of up to 3-5 mm is recommended. In the case of a well-tended lawn with soft

ground, the scarifying depth can be set slightly deeper. In case of a very mossy lawn
surface, the initial working depth should be slightly less.

Setting (figure  V2  +  T2  +  Z2 )

Set the scarifying depth as follows:
–  After loosening the counter nut, set the working depth on the adjusting screw

V2

so that the blades of the lowered scarifier (hand lever forward)

T2

  penetrate

approx. 3 to 5 mm deep into the ground.

–  Retighten the counter nut after the adjustment.
–  To lift the device from the set working position, move the lever all the way to the

back to position “transporting”. This does

not change

the set scarifying depth

Z2 !

After a few hours of operation, a readjustment of the scarifying depth becomes

necessary due to wear. The more intensively you use it, the more wear on the blades.
Hard or very dry soils accelerate the wear. In this case, proceed in the same manner

for the scarifying depth adjustment as described above.

14  SCARIFIER OPERATION

Safety information!

For explanation of symbols,

see the table on page 3

NOTE

To protect the cutter shaft, avoid tight curves and raise the cutter shaft
before  turning.

Using the machine on slopes

ATTENTION
The device can be used on banks and slopes with a gradient of up to 46%

(25°  angle). Any steeper slopes can lead to engine damage.
For safety reasons, however, we urgently recommend you do not exploit this

theoretical performance potential. Always make sure you have a firm stance.
Manually guided scarifiers should never be used for slopes with a gradient in

excess of 26% (15° angle of slope). Stability may be lost!

Checking the oil level

Check the oil level before scarifying (see the chapter

Checking the oil level and filling

with oil

). The scarifier is also fitted with an oil level sensor. If the oil level is too low, the

engine is switched off. The oil level sensor does not replace regular checks by the user.

Never let the engine run with too little or too much oil. Irreparable damages could occur.

Checking operating safety

The scarifier is fitted with an engine stop device.

Before every scarifying job, make sure that the engine stop safety control bar is working
perfectly. When the safety grip is released, the engine and the cutting tool must come to

a standstill (Note! The cutting tool runs for a while!). If this is not the case, please

consult your nearest authorised workshop.
After release, the bar must always return to the position shown in the “Description of

components” diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
Machine safety and protective devices must not be manipulated or disabled.
Make sure that all protective devices have been attached properly and are

not damaged.
To avoid danger, check the condition and tight fit of the cutter shaft before every

scarifying job (refer to the chapter “Cutter shaft care” for more details). Always have
work on the cutter shaft done by a specialist workshop. If the cutter shaft is assembled

incorrectly, parts can become loose, which can lead to serious injuries.
Also check device screws and nuts for a firm fit every 10 operating hours and tighten,

if necessary.
