handles) is maintained between the user and the hous-
ing. Be especially careful when scarifying and changing
direction on slopes and inclines. Maintain a solid footing
and wear sturdy, nonslip footwear and long trousers. Al-
ways scarify along the incline (not up and down).
For safety reasons, the scarifier may not be used to
scarify inclines whose gradient exceeds 15 degrees.
Use special caution when backing up and pulling the
scarifier (tripping hazard)!
Tips for proper working
It is recommended that you overlap scarifying paths a
little. Try to scarify in straight lines for a nice, clean look.
In so doing, the aeration swaths should always overlap
each other by a few centimetres in order to avoid bare
strips.
As soon as grass clippings start to trail the scarifier, it is
time to empty the grass basket.
Important! Before taking off the grass basket, switch off
the motor and wait until the roller has come to a stop.
To remove the grass basket, lift up the ejector flap with
one hand, while unhooking the basket with the other.
How frequently you should scarify your lawn is deter-
mined primarily by the speed at which the grass grows
and the hardness of the soil. Keep the underside of the
equipment clean and remove soil and grass build-up.
Deposits make it more diffi cult to start the aerator and
decrease the quality of the scarifying. Always scarify
along inclines (not up and down). Switch off the motor
before doing any checks on the roller.
Important!
The roller rotates for a few seconds after the motor is
switched off . Never attempt to stop the roller. In the
event that the rotating roller strikes an object, immedi-
ately switch off the equipment and wait for the roller to
come to a complete stop. Then inspect the condition of
the roller. Replace any parts that are damaged.
Cleaning and maintenance
Danger!
Always pull out the mains power plug before starting
any cleaning work.
Cleaning
• Keep all safety devices, air vents and the motor hous-
ing free of dirt and dust as far as possible. Wipe the
equipment with a clean cloth or blow it with com-
pressed air at low pressure.
• We recommend that you clean the device immedi-
ately each time you have finished using it.
• Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents or
solvents; these could attack the plastic parts of the
equipment.
Maintenance
• A worn out or damaged cutting unit should be re-
placed by an authorised expert.
• Take care that all fastening elements (screws, nuts,
etc.) are firmly tightened, so that you can work safely
with the scarifier.
• Store the scarifier in a dry place.
• For longer life, all screw-fastened parts, such as
wheels and axles should be cleaned and subse-
quently oiled.
• Regular servicing of the scarifier not only secures
longer endurance and performance, but also contrib-
utes to an accurate and simple scarification of your
lawn.
• At the end of the season, carry out a general check of
the scarifier, and remove all residue collected. Before
the start of every season, it is absolutely necessary to
check the state of the scarifier. Contact our Customer
Service if repair work is necessary.
Servicing the air filter
Soiled air filters reduce the engine output by supply too
little air to the carburetor.
Regular checks are therefore essential. The air filter
should be checked after every 50 hours of use and
cleaned if necessary. If the air contains a lot of dust,
the air filter should be checked more frequently.
• Remove the air filter as shown in Fig. 15+16.
• Clean the air filter only with compressed air or by tap-
ping it.
• Assemble in reverse order
Important: Never clean the air filter with petrol or inflam-
mable solvents.
Servicing/Replacing the spark plug
Check the spark plug for dirt and grime after 10 hours
of operation and if necessary clean it with a copper wire
brush. Thereafter service the spark plug after every 50
hours of operation.
• Pull off the spark plug boot (Fig. 17) with a twist.
• Remove the spark plug using a spark plug wrench
(Fig. 18).
• Assemble in reverse order
Preparing the equipment for storage
Caution: Do not empty the petrol tank in enclosed
areas, near fire or wen smoking. Petrol fumes
can cause explosions and fire.
Empty the petrol tank with a petrol suction pump.
