7 MAINTENANCE AND CARE
Before carrying out any maintenance
or cleaning work, pull off the sparkplug
connector!
Do not spray the unit with water. Water
which gets into the ignition system or the
carburertor may result in malfunctions.
Clean the unit with a cloth, hand brush, etc.
When the mower is tilted to the side,the
carburettor must be pointing upwards!
Expert inspection is required:
- if the lawn mower strikes an object
- if the motor stops suddenly
- if the blade is bent (do not align!)
- if the motor shaft is bent (do not align!)
- if the gears are damaged
- if the V-belt is defective
Changing the oil / air filter / spark plug
See operating manual supplied by the engine
manufacturer.
Drive gears
The gears are maintenance-free.
Replacing and sharpening the mowing
blade
At the end of the mowing season always
sharpen the mowing blade or, if required,
replace the mowing blade with a new one.
Always have the mowing blade sharpened
or replaced by a customer service centre
(measurement of imbalance).
Unbalanced blades will cause the
lawn mower to vibrate violently – risk
of accident!
Starter battery
The starter battery is recyclable.
Do not dispose of used, leaking or
defective starter batteries with the
household rubbish!
Batteries must even be taken out of units which
are to be recycled and disposed of accordingly.
Starter batteries can be disposed of in the
proper manner by your dealer or at municipal
collection points (recycling yard).

Charge the starter battery in a dryroom
only!
Do not operate the lawn mower while
the battery is being charged!
Storing the unit

frostfree location.
