brief period after the unit has been switched o. Do not tilt or
carry the unit while the motor is still running and do not touch
the cylinder while it is still rotating. Failure to comply could
result in severe personal injury.
Overload Protection
The overload protection will be activated in the following
circumstances:
1. A build up of scaried material around the cutting device.
2. If the material scaried is larger than the motor capacity.
3. Where there is too much resistance against the cutting
device.
When the circuit breaker has been activated switch o the
product and disconnect from the power supply.
Let the product cool down and eliminate the cause before
using the product again.
mWARNING! Extensive vibration of the product during
operation is an indication of damage. The product should be
promptly inspected and repaired.
• Check the machine, its power cord and plug as well as
accessories for damage before each use. Do not use the
machine if it is damaged or shows wear.
• Double check that accessories are properly xed.
• Push the machine forward by its handle. Keep the handle
dry to ensure safe support.
• Ensure that the air vents are always unobstructed and
clear. Clean them if necessary with a soft brush. Blocked
air vents may lead to overheating and damage the
product.
• Switch the machine o immediately if you are disturbed
while working by other people entering the working area.
Always let the machine come to complete stop before
putting it down.
• Do not overwork yourself. Take regular breaks to ensure
you can concentrate on the work and have full control
over the machine.
• Mow the lawn before working and fertilize afterwards.
• Make sure that the lawn is clear of stones, sticks, wire, or
other objects that could damage the machine or its motor.
• Select the suitable cutting depth for the actual grass
height.
• Do not work with this machine on a wet lawn because it
tends to stick to the underbody of the machine, preventing
the proper discharge of collected material, and it could
also cause you to slip and fall.
• Slowly push the machine forward. Move the machine at
appropriate speed. Do not move it too fast to prevent the
discharge from getting blocked and engine from useless
overloading.
• Work in slight overlapping rows. The most eective pattern
for scarifying/raking lawns is straight lines along one of the
sides. This will keep the rows even and ensures that all the
lawn is scared/raked without missing any spots (Fig. 12).
Fig. 12
General Operation
mWARNING! If the product strikes a foreign object stop
the motor. Switch the product o, disconnect it from the power
supply and let it cool down. Inspect the product thoroughly for
damage. Have any damage repaired before restarting.

Page 11
• Circle around ower beds. When reaching a ower bed
in the middle of the lawn, make a row or two around the
circumference of the bed.
• Pay special attention when changing direction.
Scarifying
Consider the weather when scarifying. Scarify the lawn with an
increased depth setting during spring time between April and
May as the lawn is better able to recover during this season.
During a wet summer scarify again in late summer with a
decreased depth setting. Do not scarify during periods of hot
weather condition. During a dry rainless summer do not scarify
a second time in autumn.
Raking
In order for a healthy lawn to develop in the spring, it is
necessary for greater amounts of air to penetrate the area
around the roots of the grass. We recommend aerating the
lawn every 4 – 6 weeks depending on the state of your lawn.
Maintenance
mWARNING! Before carrying out any repairs or
servicing work, you must ensure that the machine has been
disconnected from the power supply. Repairs and maintenance
work other than described within this instruction manual may
be performed only by qualied specialist!
Service + Storage
To ensure long and reliable service, carry out the following
maintenance regularly. Servicing and cleaning work on the
machine and the removal of the guards may only be carried
out after the motor has been switched o and the plug
disconnected from the power supply.
• Keep all nuts, bolts and screws tight to be sure the
product is in a safe working condition.
• Allow the product to cool before storing in any enclosure.
• Check the thatch collection bag frequently for wear or
deterioration.
• Examine the product regularly and replace worn or
damaged parts for safety.
• Check that covers and guards are undamaged and
correctly tted. Carry out necessary maintenance or
repairs before using the machine.
• If the cutting device should happen to fail despite the
care taken in manufacturing and testing, repair should be
carried out by an authorized repair facility.
• Do not clean the machine while it is running.
• Ensure that all the fastening elements (screws, nuts, etc.)
are tight at all times so that you can safely work with the
machine.
• Check the machine frequently for signs of wear. Replace
worn or damaged parts.
• Store your machine in a dry place. To ensure a long
service life all screws and bolts should be cleaned and
then oiled.
• Clean the machine with a brush or cloth. Do not use any
solvents or water to remove dirt.
• The component that is subject to most wear is the cutting
device. You should therefore check the condition of the
cutting device and its mounting at regular intervals.
– If the cutting device is worn or blunt it must be replaced
immediately.
– If the machine starts to suer from excessive vibrations,
this means that the cutting device has not been
balanced correctly or has suered deformation due to
impacts. In this case it must be repaired or replaced.
Replacing/Changing Cutting Device
mWARNING! Always switch the machine o, disconnect
it from power supply and let it cool down before changing/
