The scarifying depth must only be adjusted with the motor switched off!
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 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 Z2 + V2 )
On delivery, the blade shaft is in the raised position (1) Z2 .
– The scarifying depth is selected with the aid of the grey retaining element (2). Push
the retaining element gently downwards and retain again in the required position
V2 . This returning element enables you to find the set working position again at
any time.
– The blade shaft is lowered to the selected working depth by means of the black
lever (3) fitted at the left. First press the lever gently downwards, and then pull to
the stop against the retaining element (2)
V2 . To reduce the lever forces, the
machine can be lifted slightly by the upper handlebar until the rear wheels are off
the ground.
– To raise the blade shaft from the working position, the lever (3) is first pressed
gently downwards, and then pushed fully forwards. In Pos. (1), the blade shaft is
no longer engaged. This does not change the pre-set working depth
Z2 .
Scarifying test
– In case of a new machine, place the retaining element (2) in the “ MIN ” position.
– Start the motor.
– Lower the blade shaft.
– Push the machine slowly in the working direction. Check the result. If the result is
not satisfactory, raise the blade shaft, switch the motor off and place the retaining
element (2) in the next position.
– Carry out another test.
If the motor stops, or if stone impact noises are heard, switch the machine off
immediately, and set a lower working depth.
After a few operating hours, the blade shaft may need to be re-adjusted because of
wear. The more intensive the use, the greater the wear to the blades. Hard or very dry
ground will increase the wear to the blades.
Then carry out the working depth adjustment as described above.
14 GRASS COLLECTOR
Safety instruction!
See table for explanation of symbols page 2
Operation with grass collector (accessory)
The scarifier can also be operated with a grass collector (Order no. – see Original
replacement parts and accessories).
WARNING
When operating the equipment with a collecting bag, the bag must be completely
assembled and in technically perfect condition.
Attaching the grass collector to the scarifier (Illustration R1 + S1 )
– First insert the grass bag frame with the clip forward into the grass bag. Align the
upper seams of the bag with the clip.
– Press the retaining profiles of the collecting sack onto the bars of the collecting
sack frame R1 .
– Open the ejection flap of the scarifier upwards.
– Pick up the collecting sack by the carrying strap and hang it in the scarifier casing
with its two side hooks upwards S1 .
– Attach ejection flap to collector.
When using the machine, ensure that the collector is emptied in good time. The grass
collector will only collect grass properly if air can pass through it freely.
IMPORTANT
Do not clean the grass collector with hot water!
Emptying the grass collector (Illustration L )
– Switch of the motor and wait until the cutters come to a stop.
– Lift the ejection flap.
– Remove the full grass bag from the scarifier by the carrying strap – the ejection
flap closes automatically.
– Shake out of the grass bag thoroughly, holding it by the carrying strap and bottom.
Operation without grass collector
WARNING
When scarifying without grass collector the ejection flap on the scarifier housing
must always be closed (flap down).
15 SCARIFIER OPERATION
Safety instruction!
See table for explanation of
symbols page 2
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).
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!
Handling the cable during use
Position the cable in such a way that the machine can pull it along easily over the lawn
surface that has already been worked. When the machine turns the cable grip
automatically positions the cable to the other handle side. Ensure that the cable is kept
well away from the cutters and that no loops are formed. Check the mains cable
regularly for signs of damage and only use it in proper condition.
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/lever is
working perfectly. When the control bar/control lever is released the motor 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.
After release, the bar/lever 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.
Check the upper part of the bar (insulation) for damage. If the casing should be
damaged, contact the nearest authorised workshop without delay, since otherwise
injuries (electric shock) can occur through touching the live parts.
Also check machine screws and nuts for a firm fit every 10 operating hours and tighten
if necessary.
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).
WARNING
Always have a specialist workshop carry out work on the cutter blade shaft, open
or remove any covers connected with the device, since an insulation protection
test must be always be carried out following repairs or maintenance work on
insulated parts (e.g. cutter blade shaft, attachment parts, covers) in line with
standard DIN EN 60335.
In addition, a wrongly assembled cutter blade shaft can lead to parts becoming
loose and causing serious injuries.
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
