OPERATION
USING YOUR TOOL
To maintain a well-cared-for lawn it should be dethatched every 4 to 6 weeks.
Scarifying with the blade cylinder is a more intensive treatment than dethatching and should only be
carried out once a year. The best time is in spring after the lawn has been mown for the rst time.
How to use your scarier
■ By scarifying you remove the hardened surface, grass felt, and at-growing weeds and the crusted
over grassroots are loosened up. The lawn will start to breathe again and assimilate nourishing
substances such as oxygen and water. This also prevents bacteria from growing in the lawn felt
when the grass is dormant.
■ Cut the grass to a height of about 1.57 inch (40 mm) before scarifying. The lawn must be dry when
using the tool. The best time for scarifying is any time during the vegetative season, from end of
April through to September. Scarify it at least once a year. We recommend using a fertilizer straight
after airing if you want a healthy lawn.
How to use your dethatcher
■ By dethatching you remove the dead matter, moss, and weed that disgures a lawn. The build-up
of dead grass provides a mat of absorbent bers which prevents water from getting through to the
ground.
■ Do not force your dethacther through grass that is longer than 2.95 inch (75 mm). The lawn must be
dry when using the tool. It’s recommended that your dethacther be used at the beginning and the
end of each grass cutting season to give your lawn a thorough raking. Your dethacther should also
be used after each mowing to remove any grass clippings that may be left by your tool.

OPERATION
■ The tool can be operated with or without the collection bag.
Recommendation: Work with the collection bag for dethatching and without the collection bag for
scarifying.
■ To ensure that the safety guard ap closes properly, remove any earth that may have collected on
the safety guard springs and/or the housing. When working without the bag, check that the safety
guard ap is tightly closed.
■ Mow the lawn to the required grass height.
■ Do not use the scarier in long grass. It may otherwise wind around the scarier blade and result in
damage to the tool.
■ Select the appropriate working or readjustment position (in the event of cylinder wear) so that the
tool is not overloaded.
■ Commence work in the vicinity of the power socket and proceed away from the socket.
■ Guide the tool at a walking pace down lanes that are as straight as possible. To ensure
uninterrupted scarifying/dethatching the individual lanes should always overlap by 2 to 3 inches.
Dwelling too long at the same place while the tool is running can damage the lawn.
■ After work and to transport the tool, remove the battery packs and wait until the cylinder is standing
still.
■ Adjust the position to the transport position (0 setting) (see Setting the Working Positions) when
transporting the tool.
■ Lift the tool to transport it oversteps and sensitive surfaces (e.g., tiles).
■ Always clean the tool after each use (see Maintenance).
■ After having treated lawns with dense moss growth, it is advisable to reseed the lawn so that it can
regenerate itself more quickly.
When working on slopes always proceed across the slope. Be particularly careful when walking
backwards and pulling the tool. There is a possible danger of stumbling.
NOTE: The shorter the grass, the better the lawn can be treated. Furthermore, the load on the tool is
less and the service life of the cylinder is prolonged.
