Functional description  
The lawn scarifier is pushed by hand  
over the area of grass to be cut.  
The unit is powered via the power  
cord. The cutter deck is driven by  
an electric motor. The cutter deck  
rotates and removes the felt layer  
formed by moss, lichen and weeds  
and conveys the scarified material to  
the outside or into the grass catcher.  
The working depth is specified

About aeration  
Information on all types  
In order that a healthy lawn can  
develop in the spring, it is necessary  
for greater amounts of air to pene-  
trate the area around the roots of the  
grass. During this period the lawn  
must be scarified more frequently  
than in the summer.  
Wear on the blades will make it  
necessary to re-adjust the depth  
of cut at a later date. An optimum  
working depth is obtained when  
the blades of the cutter are inserted  
2–3 mm into the ground.  
If the working depth is too deep,  
this can overload the scarifier and  
cause damage. Ensure that the  
depth of cut setting is correct.  
Note  
When the cutter deck is in contact  
with the ground, the unit can move.

Only scarify the lawn when the grass  
height is less than 4 cm. If the grass  
has exceeded this length, the lawn  
should be mown before it is aerated.  
Apply fertiliser to the areas that have  
been scarified and water it in, so that  
fresh grass can grow more quickly.

The best method is to clean the  
grass sack straight after you have  
finished scarifying.  
– Detach and empty the grass sack.  
– The grass catcher may be  
cleaned with a powerful jet of  
water from the garden hose.  
– Allow the grass sack to dry out  
thoroughly before using it again.
