12 EMERGENCY STOPPING

Release the safety grip.
– The cutters will stop. Attention! The cutting tool runs for a while!
– The engine will stop.
NOTE
Before every scarifying job, make sure that the safety control bar is working
perfectly.
– When the control bar is released, the engine must switch off and the cutting
tool must come to a standstill (Note! The cutting tool runs on for a while!).
If this is not the case, please consult your nearest authorised workshop.

13 ADJUSTING THE SCARIFYING DEPTH

The scarifying depth must only be adjusted with the motor switched off!
To work with the scarifier, the scarifier lever is pushed forward into the "scarify" position
T2 . This lowers the machine 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 blade shaft lowered, the blades 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 working depth can be set slightly deeper. In case of a very mossy lawn
surface, the initial working depth should be slightly less.

Setting (Illustration 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

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

Using the machine on slopes

NOTE
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 Check the oil level and fill with
oil). Never let the engine to run with too little or too much oil. Irreparable damages
could occur.

Checking operating safety

The scarifier is equipped with a motor stop device.
Before every scarifying job, make sure that the motor stop safety control bar is working
perfectly. When the control bar is released, the engine and the cutting tool must come

to a standstill (Note! The cutting tool runs on 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 "component
description" 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 blades before every
scarifying job (refer to the chapter "Cutter blade shaft care" for more details). Always
have work on the cutter blade shaft done by a specialist workshop. If the cutter blade
shaft is assembled incorrectly parts can become loose, which can lead to serious
injuries.
Also check machine screws and nuts for a firm fit every 10 operating hours and tighten
if necessary.
Make sure the spark plug connector is fitted tightly. Risk of electric shock. Never pull
the plug connector off with the engine running. Risk of electric shock. Only pull the plug
connector off if the engine has cooled down. Risk of burns.
If the cutter blade shaft becomes blocked e.g. by colliding with an obstacle or through
foreign objects, have an authorised workshop check whether any parts of the scarifier
are damaged or deformed. Always have any necessary repairs done by an authorised
workshop too.
If the machine starts to vibrate unusually heavily or to make unusual noises, please
have it checked immediately by an authorised workshop.

Time restrictions

The time at which scarifiers may be used varies from region to region. Please ask the
relevant authorities before using your scarifier.

Tips on caring for your lawn (Illustration M )

When using the machine, always guide it in straight lines at medium walking speed.
Due to the forward direction of rotation of the blade shaft, only a slight pushing force is
required. Depending on the properties of the surface, it may be necessary to hold the
machine back against the working direction. Avoid moving in tight curves.
On very mossy and weedy lawns, it is advisable to apply the scarifier a second time, at
right-angles to the first working direction. Remove the loose grass from the lawn before
the second run. Loose grass lying on the lawn will have an adverse effect on the result,
put an additional strain on the machine and make the work unnecessarily difficult for the
user (stronger pushing forces).
Loose materials can best be removed by vacuuming with a TurboStar lawn mower or
manual raking.

15 SERVICE INTERVALS

IMPORTANT
Avoid damage! Under extreme or unusual conditions, shorter servicing intervals
than the ones specified below may be necessary. If you establish any problems,
please contact an authorised workshop.
Carry out routine servicing on the machine in line with the following servicing intervals.
Work must be carried out at the following servicing intervals in addition to the
maintenance work listed in these operating instructions.
Before initial use
• Check the oil level Y1 .
• Check all screw connections for a tight fit.
• Check the cutter blade and have an authorised workshop tighten it if necessary.
• Check whether the safety control bar is working properly.
• Check that all protective devices have been attached properly and are not
damaged.
Before every operation
• Check the lawn area and remove any objects.
• Check the area of the boundary wires (if an automatic mower is being used for
lawn care).
• Check the oil level Y1 .
• Check the condition and firm fit of the blades and have them replaced or tightened
by an authorised workshop if necessary.
• Check whether the safety control bar is working properly.
• Check that all protective devices have been attached properly and are not
damaged.
Every 10 operating hours
• Check all screw connections for a tight fit.
