For breaking soil or deep tilling, allow the tines to pull the tiller forward to the end of your arm’s reach,
then firmly pull the tiller back towards you. By repeatedly allowing the tiller to move forward and then
pulling back to you, the tiller will be most effective.
If the tiller digs deep enough to stay in one spot, gently rock the tiller side to side to start the tiller
moving forward again.
For preparing seed beds, we recommend using one of the tilling patterns shown in Fig. 5.
Tilling Pattern A –Make two passes over area to be tilled, the second at a right angle to the first.
Tilling Pattern B –Make two passes over area to be tilled, the second overlapping the first.
To prevent tripping take particular care when moving backwards and when pulling the tiller.
Always let the tines rotate at top speed; do not work in such a way as to overload the appliance.
Never pass the tiller over the extension cord; make sure it is always in a safe position behind your back.
When working on inclines always stand diagonally to the incline in a sturdy, safe stance. Do not work
on extremely steep slopes.
Transport
Caution! Before transporting the appliance, switch off the motor and unplug it.
The tines and the unit may be damaged even if you move the appliance with the motor switched off, e.g.
over solid ground. Prevent the tines from touching the ground by carrying the appliance by its guide bar.
Cleaning tines and foreign objects
During operation, a stone or root could become lodged in the tines, or tall grass or weeds may become
wrapped around the tine shaft.
To clear the tines, release the trigger lever. Unplug the tillter, and dislodge or remove any obstacles from
the tines or tine shaft.

Intended Use
This appliance is only intended as an electric tiller for lawns and grassy areas in private domestic and hobby
gardens.
It is not designed for use in public areas, parks, sports areas, and in agriculture and forestry.
Using the appliance for any other purpose is considered incorrect and unapproved. The manufacturer is not
liable for any damage or injury resulting from such use. The user is entirely responsible for any associated
risks.
Double insulation
The electric tiller has double insulation. This means that all external metal parts are insulated from the
electrical supply.
This is achieved by introducing an insulation layer between electrical and mechanical parts. The double
insulation guarantees you the greatest possible safety.
Overheat protection
If the appliance is blocked by a foreign object or if the motor is overloaded, the motor will switch off
automatically by the protection device. Release the trigger level and wait until the motor cools down
(approx. 15 minutes) then start the appliance again.
Noise/vibration information
Measured sound values determined according to EN 709.
The vibration emission level given in this information sheet has been measured in accordance with a
standardised test given in EN 709 and may be used to compare one tool with another.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main application of the tool. However if the tool is
used for different applications, with different accessories or poorly maintained, the vibration emission may
differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is
switched off or when it is running but not actually doing the job. This may significantly reduce the exposure
level over the total working period.
