proper working
It is recommended that you overlap scarifying paths a little. Try to scarify in straight lines for a nice, clean
look. Insodoing, the aeration swaths should always overlap each other by a few centi

meters in order
to avoid bare strips.
As soon as grass clippings start to trail the scarifiers, it is time to empty the grass basket.
Important!
Before taking o
ff
the grass basket, switch o
ff
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 determined 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

Always scarify along inclines (not up and down). Switch o

the motor before doing any checks on the
roller.

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.
