Battery Pack and Charger

cool, dry area. Wet, damp areas can cause corro-
sion of terminals and electrical contacts. If stored for
long periods in high temperatures (120° F / 49° C),
permanent damage to the battery pack can result.
Check electrical terminals and contacts on battery
packs and charger. Wipe with clean cloth or blow
clean with compressed air.

• Regular, careful maintenance is required to guaran-
tee the safety level and performance of the machine.
• Make sure that all nuts, bolts and screws are tight-
ened securely and that the machine is in safe work-
ing condition.

and impaired functionality.
Regularly clean the grass box with water and let it
dry thoroughly.

only be done in the open air using a petrol suction
pump (available from DIY shops).

For safety reasons you should only ever have your blade
sharpened, balanced and mounted by an authorized
service workshop. For optimum results it is recommend-
ed that the blade should be inspected once a year.

Damaged blades
Should the blade, in spite of all precautions, come into
contact with an obstruction, shut down the engine im-
mediately and pull the spark plug boot. Tip the lawn
mower onto its side and check the blade for damage.
Damaged or bent blades must be replaced. Never at-
tempt to bend a bent blade back to straight again. Nev-
er mow the lawn with a bent or heavily worn blade as
this will cause vibrations and can lead to further dam-
age to the lawn mower.
m CAUTION! There is a risk of injury if you work with
a damaged blade.
Resharpening the blade
The blades can be resharpened with a metal file. In
order to avoid imbalance, the blade should be resharp-
ened by an authorized service workshop
Checking the oil level
m CAUTION! Never run the engine with no or too little
oil. This could cause severe damage to the engine. Use
only SAE30 engine oil.

• Stand the lawn mower on a flat level surface.
• Unscrew the oil dip stick (12) by turning anticlockwise,
pull out and wipe. Insert the dip stick back in the filling
mount as far as the stop, but do not screw back in.
• Pull out the dip stick (12) again and read off the oil
