Operating the Lawn Mower

14.1 Holding and Guiding the Lawn Mower ► Hold the handlebar with both hands so the thumbs enclose the handlebar.

14.2 Adjusting the Cutting Height
Six cutting heights can be set:
– 25 mm = position 1
– 30 mm = position 2
– 40 mm = position 3
– 50 mm = position 4
– 60 mm = position 5
– 75 mm = position 6
The positions are indicated on the lawn mower. ► Hold the lawn mower at handle (1).
► Press and hold lever (2).
► Move the lawn mower to the desired position by raising and lowering the lever.
The current cutting height can be read off at cutting height indicator (3) by means of marking (4).
► Release lever (2).
The lawn mower engages.

14.3 Activating ECO Mode
When ECO mode is activated, the lawn mower detects the current working conditions and adjusts the blade speed automatically.
This may extend the battery life. ► Open flap (1) as far as the stop and hold.
► Set ECO switch (2) to the I position.
► Close flap (1).

14.4 Mowing ► If working with self-propulsion engaged: drive the lawn mower forwards in a controlled manner.

14.5 Emptying the Grass Catcher Box The flow of air generated by the blade raises level indicator (1). The flow of air stops when the grass catcher box is full. If the flow of air is too low, level indicator (2) returns to its resting state.
This is a prompt to empty the grass catcher box.
The functionality of the level indicator is restricted if the flow of air is impaired. External influences such as wet, dense or high grass, low cutting levels, contamination or the like can impair the flow of air and the functionality of the level indicator.
► If the level indicator drops to its resting state: empty the grass catcher box.
► Switch the lawn mower off. ► Set driving speed lever (1) to the position.
► Detach the grass catcher box. ► Open tab (1).
► Open upper part of grass catcher box (2) by handle (3) and hold.
► Hold lower handle (4) with the second hand.
► Empty the grass catcher box.
► Close the grass catcher box.
► Attach the grass catcher box.

Safety Information for Lawn Mowers

27.1 Introduction
This chapter describes the general safety instructions preformulated in the standard EN 60335-2-77, Annex EE, for electrically operated lawn mowers.

WARNING
■ Read all the safety instructions, instructions, illustrations and technical data provided with the lawn mower. Failure to comply with the following instructions may cause electrical shock, fire and/or serious injury. Keep all safety instructions and instructions for the future.

27.2 Training
a) Read the instruction manual carefully.
Ensure that you are familiar with the controls and the correct use of the machine;
b) Never allow children or other persons who are not familiar with the instructions for use to use the lawn mower. Local regulations may specify a minimum age for users;
c) Never mow in the vicinity of other persons, particularly children or animals;
d) Be aware that the person operating the machine or the user is responsible for accidents involving third parties or their property.

27.3 Preparatory Measures
a) Always wear sturdy shoes and long trousers when operating the machine. Never operate the machine barefoot or in lightweight sandals. Avoid wearing loose clothing or clothing with hanging cords or belts.
b) Inspect the area on which the machine is to be used and remove any objects that could be taken in and thrown up by the machine.
c) Before using the machine, always visually inspect the cutting blade, the retaining pins and the entire cutting unit for wear or damage. To avoid imbalance, worn or damaged cutting blades and retaining pins must be replaced in pairs. Worn or damaged warning signs must be replaced.

27.4 Handling
a) Only mow during the day or with good artificial light.
b) If possible, avoid using the machine when the grass is wet.
c) Always ensure good stability on slopes.
d) Operate the machine only at walking pace.
e) Only mow across and never up or down the slope.
f) Be particularly careful when changing direction on a slope.
g) Do not mow on excessively steep slopes.
h) Be particularly careful when turning the lawn mower around or pulling it towards you.
i) Stop the cutting blade(s) when the machine needs to be tilted for transportation over surfaces other than grass and when moving the lawn mower from and to the area to be mown.
j) Never use the lawn mower with damaged safety devices or protective grilles or without attached safety devices, e.g. deflectors and/or grass-catching units.
k) Exercise care when starting or pressing the starting switch and observe the manufacturer’s instructions. Ensure that you keep your feet far enough away from the cutting blade(s).
l) The lawn mower must not be tilted when starting it, unless the lawn mower needs to be lifted during the process. In this case, only tilt it as far as is absolutely necessary and only raise the side facing away from the user.
m) Do not start the motor when you are standing in front of the discharge chute.
n) Never put hands or feet on or underneath rotating parts. Always keep away from the discharge opening.
o) Never lift or carry a lawn mower with the motor running.
p) Stop the motor and pull out the starting key.
Ensure that all moving parts have come to a complete stop:
– whenever you leave the lawn mower;
– before remedying blockages, including those in the discharge chute;
– before checking, cleaning or working on the lawn mower;
– after hitting a foreign object. Inspect the lawn mower for damage and perform the necessary repairs before re-starting and using the lawn mower.
If the lawn mower begins to vibrate excessively, it must be checked immediately.
– Check for damage;
– make the necessary repairs to damaged parts;
– ensure that all screws, pins and bolts are tightly fastened.

27.5 Maintenance and Storage
a) Ensure that all nuts, pins and bolts are tightly fastened and that the machine is in a safe working condition.
b) Check the grass-catching unit regularly for wear or loss of functionality.
c) In the interests of safety, replace all worn or damaged parts.
d) Be aware that on machines with more than one cutting blade, the movement of one cutting blade can cause the other cutting blade to turn.
e) Ensure when adjusting the machine that your fingers do not become pinched between moving cutting blades and stationary parts of the machine.
f) Allow the motor to cool down before storing the machine.
g) Note when maintaining the cutting blades that the cutting blades can be moved even if the power source is switched off.
h) In the interests of safety, replace all worn or damaged parts. Only use genuine spare parts and accessories.
