Always wear ear protection!

The declared values for vibration and noise, which have been measured according to a standardised test method, can be used to compare different tools with each other and for a preliminary assessment of exposure. Noise emission has been measured and declared in accordance with ISO 11094:1991, EN ISO 3744:1995, EN ISO 3744:2010

WARNING!

The actual vibration and noise level when using tools may differ from the specified maximum value, depending on how the tool is used and the material. It is therefore necessary to determine which safety precautions are required to protect the user, based on an estimate of exposure in actual operating conditions (taking into account all stages of the work cycle, e.g. the time when the tool is switched off and when it is idling, in addition to the start- up time).

DESCRIPTION

Silent robot lawn mower with a digital display screen and rain sensor. Charging station, perimeter wire, wire pegs and nine blades are included.

INSTALLATION

INSTALLATION OF CHARGING STATION

IMPORTANT:

• The charging station must be positioned on level, horizontal ground. It must not be installed on a slope. The surface must be flat so that the base plate is not buckled or creased.
• The charging station can be placed next to a shed or house wall. Position the charging station where there is at least 1 m of straight perimeter wire with no obstacles in front of the charging station.
• The mains adapter should be mounted on a wall, at least 30 cm off the ground. The low voltage cable should be laid outside the mowing area, if possible. If it is necessary to lay the cable partly or completely inside the mowing area, the cable must be buried.

FIG. 1
FIG. 2

1. Strip approx. 10 mm of insulation off one end of the perimeter wire.

FIG. 3

2. Connect the perimeter wire to one of the terminals. The red terminal (A) is the system’s OUT direction. Pull the connected perimeter wire through the opening in the charging station base plate. Lay out the perimeter wire and peg it to the ground along the edge of the mowing area. When the perimeter wire has been laid completely and you are back at the base station, cut off the excess wire, strip 10 mm of insulation off the end of the wire and connect it to the other terminal.
The black terminal (B) is the system’s IN direction.

FIG. 4

INSTALLATION OF PERIMETER WIRE

NOTE:

The maximum permitted length for the perimeter wire is 300 m.

1. The perimeter wire should be laid 25 cm inside the edge of the mowing area – use the distance gauge to measure this. It may be necessary to set the pegs closer together where the ground is uneven.

FIG. 5
FIG. 6

2. Where the mowing area is crossed by paths, driveways etc. that are level with the ground and the mower can travel over them, the perimeter wire distance can be reduced from 30 to 8 cm.

FIG. 7
FIG. 8

Protected zones and narrow passages

The perimeter wire can be laid in a loop to create an island around flower beds, shrubs, trees, ponds and similar obstacles and zones where you don’t want the mower to go. When creating an island, the passage for the mower must be at least 0.8 m wide.

FIG. 9
FIG. 10

Corners

Corners should be laid with obtuse angles (90° or larger) and the perimeter wire must run completely straight to the corner from both sides.

FIG. 11
FIG. 12

Slopes

The robot lawn mower is able to climb slopes up to 35% (20°) without any problem. Avoid areas steeper than this. Measure and calculate as shown below.

FIG. 13

CONNECTING THE CHARGING STATION TO THE POWER SUPPLY

• Insert the mains adapter plug into a suitable power outlet. If the perimeter wire is correctly installed, the charging station status light will be a steady green. Errors are also indicated by the status light. See below.

FIG. 14

Status light is off:
