Important - Please read these instructions
fully before starting assembly.
IMPORTANT!
When using this equipment, the following
safety
precautions must be followed to avoid
injuries and damage:
• Read all operating instructions carefully and
comply with them. It is important to
understand these instructions and to
acquaint yourself with the machine, its
correct usage and all safety requirements.
• Keep this manual in a safe place so that the
information is available to the operator at all
times.
• If you give the equipment to any other
person, give them these operating
instructions as well. We accept no liability
for damage or accidents which result from
non-compliance with these instructions.
NOTE: Only supply power to the equipment
through a circuit protected by an RCD with a
maximum trip current of 30mA.
• Use only plugs or connectors approved for
outdoor use.

4
• Extension cables must comply to H05VV-
F requirements as described in DIN 57
282/VDE 0282 and must have a minimum
cross-section of 1.5mm2. The plug must
have an earth and any connection must also
be earthed and splashproof. Before use,
check the cables for signs of damage and
ageing. Never use the mower if the cables
are not in perfect condition (this also applies
to the supply cable on the mower). If the
cable is damaged whilst the mower is
working, disconnect the mains plug from the
power supply immediately and then check
the extent of the damage.
• Never allow children or people unfamiliar
with these instructions to use the mower.
Local regulations may restrict the age of the
operator.
• This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision or
instruction concerning use of the appliance
by a person responsible for their safety.
• Children should be supervised to ensure
that they do not play with the appliance.

5
Personal safety
• Always check the mower for signs of damage
before each usage.
• Always disconnect the mains lead from the
electrical supply before carrying out any
inspection, servicing or maintenance work.
• Ensure that all the guards are securely fitted
and in good working order.
• Check the grass collection bag at regular
intervals for signs of wear and to ensure that
it is always in perfect working order.
• Before each use, inspect the mower to
check the cutting blade, fastening bolts
and the entire cutting unit for any signs
of wear or damage. To prevent imbalance
or vibration, worn or damaged cutting
blades and fastening bolts must always be
replaced in full.
• Damaged parts on the mower must be
replaced by qualified personnel. Use only
genuine spare parts.
• In areas where the mains supply is weak or
bearing a high load, this mower may cause
further voltage fluctuations as it starts. In
extreme cases, this can cause damage to
other equipment working from the same
supply. In this case, we recommend to
temporarily switch off any un-required
equipment or connect it to a different circuit.

6
• Repair work on the electrical parts of the
lawn mower may only be carried out by a
qualified electrician.
• Follow the instructions to fit or remove the
blade and wear protective gloves.
• Only work in good daylight or appropriate
and adequate artificial light.
• Never use the mower when you are tired.
• Never run the mower in enclosed or poorly
ventilated rooms or if there are flammable
or explosive fluids, vapours or gases nearby.
• If the mower has struck a foreign object,
switch off the motor and disconnect the
mains lead before you inspect it or clear any
blockages in the grass ejection area.
• Always use the lawn mower with the grass
collection bag correctly fitted.
• Check the site on which you intend to use
the lawn mower and remove all objects that
may be caught or thrown up by the mower.
• Foreign bodies must be removed before
you start mowing. Keep an eye on the power
cable and keep it away from the cutting
blade at all times.
• Ensure that you do not push the mower
over areas that might damage or snare the
power cable.
• Never lift the lawn mower when you start the
motor.

7
• Before you lift the lawn mower to transport
it, switch off the motor, disconnect the
mains lead and wait until the blade has
come to a complete standstill.
• When you start the motor, the lawn mower
should not be tilted unless the grass is
particularly long. In this case, only tilt it up as
far as is really necessary, and only raise the
side that is furthest away from you.
• Never reach towards rotating parts with your
hands or feet. Always keep away from the
discharge chute.
• Before you attach or empty the grass
collection bag, switch off the motor and
wait until the blade has come to a complete
standstill.
• Make sure you keep your feet at a safe
distance from the mower blade at all times!
Do not stand near the grass ejection chute if
the grass collection bag is not fitted.
• The safety distance from the moving blade
produced by the push handle must be
maintained at all times.
• If you use the mower on a small incline, mow
across the slope (not in an up and down
direction). Always be sure of your footing
on slopes.
• Be particularly careful when changing
direction with the mower whilst working on a
slope.

8
• For safety reasons, do not use the mower on
gradients exceeding 15°.
• Ensure that you have safe footing at all
times whilst working with the mower.
• Always wear strong, anti-slip footwear and
long trousers when using the mower. Never
mow in bare feet or in open-toed sandals.
• When the mower is running, ensure that
no person or animal, particularly children
and pets, are in the immediate vicinity of
the lawn mower. Ensure that you keep
everybody at least 10 metres away from the
mower when it is working.
• Switch off the motor and disconnect the
plug from the power supply if the mower
strikes a foreign body. Check the mower for
signs of damage and carry out all necessary
repair work before you start the mower
again.
• If the lawn mower begins to vibrate
abnormally, switch it off immediately,
disconnect the plug and check it carefully.
Ensure that all the nuts, bolts and screws
are tight and that the mower is in a safe
condition for use.
• Do not leave the mower out in the rain. The
lawn must not be wet or very damp.
• Only push the mower at a normal walking
pace.

9
• Be particularly careful when you change the
direction of the mower or pull it towards you.
Avoid pulling it towards you while the blade
is moving.
• Switch off the mower if it has to be pushed
over surfaces other than grass, and when
moving the mower to and from the area you
wish to mow.
• Carefully operate the starter switch in
accordance with the instructions.
• Do not switch the mower on and off
frequently over a short period of time, and
in particular, do not play with the ON/OFF
switch.
• Do not touch the cutting blade until the
machine has been disconnected from the
mains and the cutting blade has reached a
complete standstill.
• Never lift or carry the mower whilst the
motor is running.
• Switch off the motor and disconnect the
plug whenever you leave the lawn mower.
• Keep the lawn mower in a dry place which is
inaccessible to children at all times.

Step 1 – Assembling handles
1. To fix the lower handle bar (5) into position, use washers (4c) and
tighten the quick-release levers (4) in a clockwise direction and then
lock them into position by folding the levers snug against the handle
support (Fig. 1). These levers should be folded in towards the bar using
moderate force to lock them in position. If they feel too tight when you
fold them, turn them anticlockwise to loosen them and then attempt
to fold them again. Do not use excessive force.
Adjust the lower handle to the desired operating position. There are
three possible positions .
2.The top handle bar (3) is assembled to the lower handle bar (5) using
bolts (4b), cable guides (4a), and quick-release levers (4) on either side
(Fig. 2). There are two possible positions. Select the position appropri-
ate for the height of the user.

WARNING! Ensure the power cord is disconnected from the
mains supply before adjusting the cutting height.
A higher cutting height should generally be selected for the first cut of
the season. When cutting longer grass, cut the grass in 2 or more passes
by lowering the cutting height gradually at each pass. These techniques
will help to avoid over-stressing your grass.
To adjust the cutting height, gently pull the cutting height adjuster (8)
towards you to disengage it from its existing position and move it to the
desired cutting height position (Fig. 9). Ensure it clicks back firmly into
position.
