First insert the safety key and turn it. Press and hold the start button, then pull the handle towards the handlebar. Release the start button. The mower only runs at full speed when it detects grass.

How to adjust the cutting height?

With the engine off and blade stationary, press the release lever on the side. Push the lever forward for a lower cut (min. 3 cm) or backward for a higher cut (max. 7 cm). Release the lever to lock it in place.

How long does it take to charge the battery?

Full charging takes about 2 hours. The green LED on the charger blinks during charging and stays on when the battery is fully charged.

What to do if the engine stops during mowing?

This may be due to a dull blade or overload. Turn off the mower, remove the safety key, move it to a flat short-grass area, and restart. If the problem persists, have the blade sharpened by an authorized service.

STARTUP

Charging the battery (1)

The battery is supplied partially charged! Fully charge the battery before the first use.

The battery can be charged in any charge level. Interrupting charging does not damage the battery.

CAUTION!

When pulling out the battery, press and hold the engagement button on the underside of the battery so the battery will be unlocked.

1. Push the battery into the charger (1a) and connect the charger to the mains (1b). Charging starts, and is indicated by the green light-emitting diode (LED) flashing.
2. The battery is fully charged when the LED of the charger lights up green without flashing.
3. Disconnect the plug from the mains (1b).
4. Pull the battery out of the charger. (1a)

	Green LED lights: battery 100% - 50% charged
	Green LED flashes: battery 50% - 25% charged
	LED lights red: no battery inserted in charger

The temperature range for the charging process should between 0^ C and +40^ C.

The maximum time for a full charge is 2 hours. If the operating period of the battery is greatly reduced in spite of a full charge, the battery is worn out and should be replaced with a new original battery.

Inserting the battery (2-5)

1. Press on the battery cover on the mower to open it.(2)
2. Remove the safety key from the mower.(3a)
3. With a slight pressure push the battery into the battery compartment up to the stop until the battery sits firmly on the contact plug of the mower. (4)
4. Insert the safety key again and turn it.(3b)
5. Press once on the battery cover to close it. (5)

OPERATION

Adjusting the cutting height (6)

CAUTION!

Danger - risk of injury!

Adjust the cutting height only while motor is switched off and the cutting blade has stopped!

1. To unlock, press the lever to the side and hold (4).
   For a short lawn slide the lever in the direction of the front wheel. Minimum step 1: 3 cm
   For a longer lawn slide the lever in the direction of the rear wheel. Maximum step 6: 7 cm
2. Release the lever and slide it forward or backward until it engages in the desired step.

Attaching the grass catcher (7)

CAUTION!

Danger - risk of injury!

Remove or replace the grass catcher only while the motor is switched off and the cutting blade has stopped.

1. Lift up the baffle plate and hang the grass catcher into the holders. (7a-b)

Level indicator (8)

The level indicator is pressed upwards by the air stream during mowing (8a). When the grass catcher is full, the level indicator rests against the catcher (8b). The grass catcher needs to be emptied.

Emptying the grass catcher (9)

3. Empty grass catcher.
4. Lift up the baffle plate and hang the grass catcher back into the holders. (7)

Switching on the motor (10)

The motor of this lawnmower does not accelerate to its full speed immediately when the motor is started.

Only when you move the lawnmower onto the grass to be mown does it detect the grass and accelerate the motor to the maximum blade speed, then it remains at the maximum blade speed.

This audible increase in the motor's noise level is completely normal and means that the lawnmower is cutting at the optimum blade speed.

Start the lawn mower only on level ground, and not in high grass. The ground must be free from foreign objects, such as stones. Do not lift or tilt the lawn mower to start it.

1. Insert the safety key again and turn it (3b).
2. Keep the start button pressed (10a).
3. Pull the safety bar toward the handle bar and hold it there (10b).
4. Release the start button.

Check the charge level of the battery while mowing the lawn (12)

1. Switching off the motor (11).
2. Open the battery compartment (2).
3. Press the test button on the battery: If the LED lights up green, there is still charge in battery and you can continue mowing. If the LED lights up red, the battery is discharged and requires recharging (12).

Switching off the motor (11)

1. Release the safety bar.
2. Wait until the cutter blade stops.
3. Remove the safety key from the mower (3a).

INFORMATION ON WORKING

Observe the local regulations on operating lawn mowers.

■ Remove foreign objects from the working area.
- Keep others away from dangerous areas.
■ Use the mower only if visibility is good
■ Guide the machine at walking pace.
■ Mow only with a sharp cutting blade
Do not mow over obstacles (e.g. branches, roots of trees).
■ Mow only across slopes. Do not use the mower up or down slopes and not on slopes with more than a slant of 20 degrees.
■ Added care must be taken on slopes when changing direction
The operating period of the lawn mower battery depends on the condition of the battery, the condition of the lawn and the setting of the cutting height. Frequently switching the mower on and off reduces the operating time
- # Optimum operating time is obtained by frequent mowing of the lawn and maintaining a short-cut lawn

Operating time at 100% battery charge in m ^2 per battery

• Cut of 6 cm to 4 cm: Up to 300 m² for well-cared for, dry lawn; thin grass
• Cut of 8 cm to 4 cm: Up to 200 m² for normal grass
• Cut of 8 cm to 4 cm: Up to 150 m² for dense grass

Mowing tips

• Constant cutting height 3–5 cm, do not cut more than half the height of the lawn
  Do not overload the lawn mower! If the motor speed is greatly reduced due to long, heavy grass, raise the cutting height and mow several times
  ■ Since wind and sun can dry out the lawn after mowing, mow the lawn in the late afternoon

STORING THE BATTERY-OPERATED LAWN MOWER

Storage

Fold the upper handle bar to save space during storage

■ Always store the mower with the battery and the safety key removed
