IMPORTANT! Set the cutting height only when the motor is switched off and the power cable has
been disconnected.
The cutting height is adjusted as shown in Figs. 4a and 4b. To do this, turn the hub cap clockwise
to release the bolt (Fig. 4a) and remove the hub cap with the bolt and wheel. The wheels can now
be tted in position 1, 2 or 3 to suit the required cutting height. Fit all four wheels at the same height
so that the cutting blade rotates parallel to the lawn.
Position Cutting height
1 20 mm
2 40 mm
3 60 mm
Before you begin to mow, check to ensure that the blade is not blunt and that none of the fasteners
are damaged. To prevent any imbalance, replace blunt and/or damaged blades. To carry out this
check, rst switch off the motor and pull out the power plug.

Before you connect the mower to the mains supply make sure that the data on the rating plate is
identical to the mains data. Connect the plug to an extension cable if necessary.
IMPORTANT! To prevent the machine switching on accidentally, the lawn mower is equipped with a
safety lock-off 13 which must be pressed before switch lever 1 can be activated. The lawn mower
switches itself off when the switch is released.

Repeat this process a couple times so that you are sure that the machine functions properly. Before
you perform any repair or maintenance work on the machine, ensure that the blade is not rotating and
that the power supply is disconnected.
IMPORTANT! Never lift the safety guard if the motor is still running. The rotating blade can cause
serious injuries.
Always ensure box and safety guard are undamaged and correctly tted. Always switch off the motor
before removing the grass box.
A safe distance between the blade deck and the user is provided by the length of the handle. This
distance must be maintained at all times. Take special care when mowing and changing direction on
embankments and slopes. Ensure that you have a secure surface to stand on, wear shoes with antislip soles that offer good grip, and long trousers. Always mow across the slope (not in up or down
direction).
Do not use the mower on gradients exceeding 15° for safety reasons.
Take special care when moving backwards and pulling the lawn mower. Never pull the mower
backwards when the motor is running

Operating Instructions & Tips
Mowing Advice
We recommend that you mow in overlapping lines. Only mow with a sharp blade so that the blades of
grass do not fray. Frayed grass blades may turn yellow. To achieve a good cut, guide the lawn mower
in lines that are as straight as possible. These lines should always overlap by a few centimeters so that
you do not leave any uncut strips.
How often you need to mow your lawn depends on how fast the grass is growing. During the main
growth period mow more frequently. If the grass is longer than usual, cut it in 2 or more stages. This
will cause less stress to both the mower and the grass. Never cut the grass by more than half its
height. Keep the under side of the mower casing clean and remove all grass deposits from it. Deposits
make it more difcult to start the mower and also adversely affect the mowing quality and the grass
collection. Switch off the motor before you carry out any inspections of the blade. Remember that the
blade will continue to turn for a few seconds after the motor has been switched off. Never attempt to
stop the blade with your hand or any other object.
Check regularly that the blade is correctly secured, in good condition and sharp. If not, sharpen or
replace the blade.
If the moving blade strikes an object, stop the mower and wait until the blade has come to a complete
standstill. Then check the condition of the blade and the blade mounting. If they are damaged, they
must be replaced.
Place the mains lead in loops on the ground near the wall socket. Mow away from the socket and
cable and ensure that the mains lead is always on the section of lawn that you have already mowed so
that you do not run over the mains lead with the mower.
If you you see mown grass on the lawn whilst you are mowing it means the grass collector is full and
needs to be emptied immediately.
IMPORTANT! Before you remove the grass collector, switch off the motor and wait until the blade
reaches a complete standstill.
To remove the grass collector, raise the safety guard with one hand and remove the grass collector
holding its handle with your other hand.To maintain safety, the safety guard will close when you remove
the grass collector to seal the rear discharge opening. If any grass drops onto the ground you need
push the mower away from the area to make it easier to re-start the motor.
Do not remove grass cuttings in the mower casing or on the cutter by hand or with your feet. Instead
use suitable tools such as a brush or broom.To ensure efcient grass collection the grass collector and
in particular the soft netting must be cleaned after use.
Only t the grass collector when the motor is switched off and the blade is not moving. Raise the
safety guard with one hand and, holding the grass collector by its handle in your other hand, position it
squarely onto its support. Ensure it ts snug against the body of the mower before starting.

Maintenance
Cleaning & Maintenance
Always disconnect the mains power plug engaging in any cleaning work.
Cleaning
• Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible.
Wipe the equipment with a soft brush or blow it with compressed air at low pressure after usage.
• Clean the mower regularly with a moist cloth and some soft soap. Do not use cleaning agents or
solvents; these may damage plastic components.

Maintenance
Blade Maintenance (continued)
If the blade is blunt, it can be sharpened in a specialised workshop. If the blade is damaged or
showing signs of imbalance, it must be replaced.
Carry out the following steps to change the blade:
• Undo the fastening bolt (Fig. 6).
• Remove the blade and replace with a new one.
• When tting the blade, make sure it is installed in the right direction. The wings on the blade must
be on the top (nearest to the deck).
• Then retighten the fastening bolt. The tightening torque should be approx 25 Nm.
IMPORTANT! Always wear work gloves when engaging in any maintenance work.
Only replace the blade with a genuine replacement blade as this will ensure top performance and
safety under all conditions.
Carbon Brushes
In case of excessive sparking, have the carbon brushes checked only by a qualied electrician.
Important! Carbon brushes should only be replaced by a qualied electrician.
Maintenance and Storage
• There are no parts inside the mower which require additional maintenance.
• Store in a dry place, out of reach of children.
