7.3. RECOMMENDED TIPS FOR SCARIFYING
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 centimeters in order to avoid bare strips.
If you use the grass catcher which is available as an option, it should be emptied as soon as moss/debris
clippings start to trail behind during scarifying.
Danger! Before taking off the grass catcher, switch off the motor and wait until the
blade/sping tines come to a stop.
To remove the grass catcher, lift up the rear cover with one hand, while unhooking the grass catcher with the
other.
How frequently you should scarify your lawn is determined primarily by the condition of the lawn and soil. Keep
the underside of the equipment clean and remove soil and grass build-up. Deposits make it more difficult 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 blades/spring tines.
Danger!
The blades rotate for a few seconds after the motor is switched off. Never attempt to stop the blades. In the
event that the rotating blades strike an object, immediately switch off the equipment and wait for the blades to
come to a complete stop. Then inspect the condition of the blades/tines.
Always follow these safety instructions and notes on working practice.
8. REPLACEMENT OF THE BLADES & SPRING TINES
WARNING:
Be sure to wear work gloves.
The equipment can be assembled with the scarifying assembly or the aerator attachment.
Only replace the roller with an original Cobra assembley, as this will ensure top performance and safety
under all conditions.
To change the scarifying tines or the aerator assembly (part number 2425200001), proceed as follows.
Remove the roller
1. Remove the two screws. (Fig.5A)
2. Lift the roller on this side and pull out in the direction of the arrow. (Fig.5B)
