Danger due to contact with live parts!
Immediately remove the plug from the mains if the extension cable has been damaged or cut!
We recommend connection using an earth leakage circuit breaker (FI) with a nominal fault current of <30 mA.

• The in-house mains voltage must match the mains voltage specifications with regard to the technical data; do not use a different supply voltage.

• Only  use extension cables intended for outdoor use – minimum cross-section of 1.5 mm².
  Always unroll the cable drum completely.

• Damaged or brittle extension cables may not be used.

• Check the condition of your extension cable before every use.

• Always use the special cable tension relief for the extension cable.

• Keep the cable out of the cutting area and always guide it away from the machine.

• Never run over  the extension cable with the lawn mower.

  After faults or unusual vibrations occur in the unit
  Before loosening blockages
  Before eliminating stoppages
  After contact with foreign bodies

**** After contact with foreign objects inspect the mower for damage. Perform the necessary repairs before starting again and begin working with the lawn mower.

WORKING INFORMATION
**** Observe the local regulations on operating lawn mowers.

• Remove all foreign objects from the lawn prior to mowing
• 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

Tips for mowing

• Start mowing as close to the socket as possible.
• Always keep the extension cable on the previously mowed lawn area.
• 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.
• Mow in the morning or late afternoon to protect the freshly cut lawn from drying out.
• Mow the lawn twice per week during the strong growing phases. Mow less during periods of less rain.

Mulching with the mulching kit (option)
With mulching, the cuttings are not collected and remain on the grass. The mulch protects the ground from drying out and provides it with nutrients.
The best results are achieved by regular cutting of approx. 2 cm. Only young grass with soft blades will decompose quickly.

• Height of grass before mulching: maximum 8 cm
• Height of grass after mulching: minimum 4 cm
  **** Adapt your walking speed to the mulching and do not go too quickly.

Utilising the mulch kit
CAUTION!
Risk of injury due to rotating parts!
Remove or replace the mulch kit only while the motor is switched off and the cutting blade has stopped.

1. Remove the grass catcher (3)
2. Lift up the baffle plate and insert the mulch kit into the discharge chute. (4a)
   Mulch kit must audibly engage.
   **** If the mulch kit does not engage, the mulch kit and cutting blade can be damaged.

Removing the mulch kit

1. Lift the baffle plate. (4b-1)
2.  Release the locking on the mulch kit. (4b-2)
3.  Pull out the mulch kit.

Wheel drive (option)
Adjusting the Bowden cable
If the wheel drive can no longer be switched on or off while the motor is running, the corresponding Bowden cable must be readjusted.
CAUTION!
Risk of injury!
Only adjust the Bowden cable when the motor is switched off.

1. Turn the adjustment part on the Bowden cable in the direction of the arrow.
2.  To check the adjustment, start the motor and switch on the wheel drive.
3.  If the wheel drive still does not function, bring the lawn mower to a service centre or an authorized specialist firm.
   Oiling the drive pinion
   Oil the drive pinion on the drive shaft from time to time with spray oil.
   **** The transmission of the wheel drive is maintenance-free.

STORAGE

• Always store the unit with the mains plug pulled.
• Fold the upper handle bar to save space during storage.
• Store the mower in a dry place and inaccessible to children and unauthorized persons.

MAINTENANCE AND CARE

CAUTION!
Risk of injury!

• Always pull the mains plug before carrying out maintenance and care!
• Always wear work gloves when carrying out maintenance and care on the cutting tools!
• Non-balanced cutting blades cause serious vibrations and damage the mower.
• Regularly check the grass catcher system for correct function and wear.
• After mowing, thoroughly clean the mower with a hand broom or a cloth. Dirt and cuttings left on the underside of the mower can impair its proper function.
• Do not hose down the unit with water! Water can damage the switch/plug combination and the electric motor.
• Regularly check the cutter blade for damage. Have the blunt or damaged cutter blades sharpened or replaced only at an AL-KO service centre or authorized specialist firm.
• Resharpened cutter blades must be balanced.
• Tightening torque of the blade screw 15 Nm +5
• Ensure that all nuts, bolts and screws are firmly tightened and that the mower is in a safe condition for operation.
• Observe that on devices with multiple cutting blades, the movement of one cutting blade can lead to the rotation of the remaining blades.
• Observe when adjusting the machine that no body parts can be jammed between the cutting blades and fixed parts of the unit.
• Allow the motor to cool before turning off the  unit.
• Observe that the cutting blade can still be moved even when the voltage supply is switched off.
• Only use original replacement parts and accessories.

CAUTION!
Cutting blade and motor shaft may not be aligned if damaged!
CAUTION!
Risk of injury!
After the blade screw has been loosened five times, it must be replaced with an original blade screw!
