• Work in slight overlapping rows. The most effective pattern
for scarifying/raking lawns is straight lines along one of the
sides. This will keep the rows even and ensures that all the
lawn is scarified/raked without missing any spots (Fig. 11).

• Circle around flower beds. When reaching a flower bed
in the middle of the lawn, make a row or two around the
circumference of the bed.
• Pay special attention when changing direction.
Scarifying
Consider the weather when scarifying. Scarify the lawn with an
increased depth setting during spring time between April and
May as the lawn is better able to recover during this season.
During a wet summer scarify again in late summer with a
decreased depth setting. Do not scarify during periods of hot
weather condition. During a dry rainless summer do not scarify
a second time in autumn.
Raking
In order for a healthy lawn to develop in the spring, it is
necessary for greater amounts of air to penetrate the area
around the roots of the grass. We recommend aerating the
lawn every 4 – 6 weeks depending on the state of your lawn.
Maintenance
m
WARNING!
Before carrying out any repairs or
servicing work, you must ensure that the machine has been
disconnected from the power supply. Repairs and maintenance
work other than described within this instruction manual may
be performed only by qualified specialist!
Service + Storage
To ensure long and reliable service, carry out the following
maintenance regularly. Servicing and cleaning work on the
machine and the removal of the guards may only be carried
out after the motor has been switched off and the plug
disconnected from the power supply.
• Keep all nuts, bolts and screws tight to be sure the
product is in a safe working condition.
• Allow the product to cool before storing in any enclosure.
• Check the thatch collection bag frequently for wear or
deterioration.
• Examine the product regularly and replace worn or
damaged parts for safety.
• Check that covers and guards are undamaged and
correctly fitted. Carry out necessary maintenance or
repairs before using the machine.
• If the cutting device should happen to fail despite the
care taken in manufacturing and testing, repair should be
carried out by an authorized repair facility.
• Do not clean the machine while it is running.
• Ensure that all the fastening elements (screws, nuts, etc.)
are tight at all times so that you can safely work with the
machine.
• Check the machine frequently for signs of wear. Replace
worn or damaged parts.
• Store your machine in a dry place. To ensure a long
service life all screws and bolts should be cleaned and
then oiled.
• Clean the machine with a brush or cloth. Do not use any
solvents or water to remove dirt.
• The component that is subject to most wear is the cutting
device. You should therefore check the condition of the
cutting device and its mounting at regular intervals.
– If the cutting device is worn or blunt it must be replaced
immediately.
– If the machine starts to suffer from excessive vibrations,
this means that the cutting device has not been
balanced correctly or has suffered deformation due to
impacts. In this case it must be repaired or replaced.
