DETHATCHING TIPS
Your new dethatcher is designed to remove withered grass
and scarify the soil to allow the soil get more nutrients. It
is suggested use tine cylinder to remove withered grass,
and use blade cylinder to scarify the soil. Please review
the following recommendations for optimum dethatching
performance.
1) Avoid dethatching when the grass is wet from
rain or dew. Wet grass may form clumps which
interfere with the dethatching action and reduce
the runtime.
2) For the best dethatching performance, it is
suggested to use lawn mower to mow excess
grass before using the dethatcher.
3) For the best performance, keep the dethatcher

12
2x20V Dethatcher EN
housing free of built-up grass. From time to time
turn off dethatcher and wait for the tine cylinder
and blade cylinder to come to a complete
stop. Then Remove the battery packs and turn
dethatcher on its side. Using an object such as a
stick, wipe out any accumulation of grass around
the area of tine cylinder and blade cylinder. Be
careful of the sharp edges of the tine cylinder
and blade cylinder. Ensure to clean the area often
when cutting wet or new grass and every time
after the machine is used.
4) It is recommended to walk at normal pace, and
not to start/stop the dethatcher too often during
operation.
5) For best performance, please ensure use two
fully charged battery packs at the same time.
6) Choose the tine cylinder or blade cylinder to
operate the machine according to the different
working conditions. Please wear protective
gloves when replacing tine cylinder or blade
cylinder.
7). You will rst need to remove all debris from the
yard, including any sprinkler heads and other
obstacles. Then you will need to mow your
lawn to half of the normal height of your typical
cutting. The lower cut will allow the dethatcher to
work more effectively.
