1 2.2 Cleaning machine
Maintenance interval:

Care of the machine will protect it against
damage and extend its service life.
● Detach grass catcher box ( Ö 8.4)
Cleaning position ME 339 C:

(
Ö 8.1)
● Open ejection flap (1) with the right
hand and hold it open.
● Hold the console with the left hand as
shown and hold the ejection flap open.
Press detent lever (2) with the thumb at
the same time and hold.
● Hold the machine with the right hand at
the front handle and tilt it slowly
rearwards until the handlebar is in

standing securely.
Cleaning position ME 339:
● Fold down dual handlebar ( Ö 8.2)
● Tilt lawn mower upwards and set down
on lower handlebars (3).
Notes on cleaning:
● Clean off dirt using little water, with a
brush or with a cloth. In particular, also
clean the mowing blade. Never spray
water onto motor components, seals,
bearing points or electrical parts such
as switches.
● First, remove accumulated clipping
deposits using a stick.
● Remove dirt from the cooling air guide
(inlet slots) between the motor hood
and the lower housing to ensure that
the motor is adequately cooled.
● If necessary, use a special cleaner
(e.g. STIHL special cleaner).
1 2.3 Electric motor and wheels
The electric motor is maintenance-free.
The wheel bearings are maintenance-free.
1 2.4 Upper handlebar ME 339
Maintenance interval:
Before each use
The upper handlebar is coated with a
insulating layer. Should this layer become
damaged, the upper handlebar must be
replaced.
1 2.5 Checking blade wear
Maintenance interval:
Before each use
● Tilt mower upwards into cleaning
position (
Ö
12.2).
● Clean mowing blade (1).
● Use a slide calliper (2) to measure
blade thickness at 5 points at least. In
particular, minimum thickness must
also be ensured in the area of the blade
wings.
● Place a ruler (3) against the front blade
edge and measure permissible
grinding.
Wear limits:
Blade thickness: > 1 ,6 mm
Permissible grinding: < 5 mm
The blade must be replaced,
– if it is damaged (notches, cracks),
– if the measured values are achieved at
one or more points or are outside the
permissible limits.
Risk of injury!
Before tipping up the mower, place
it on firm, level and flat ground. The
machine may tip over when working
on it in the cleaning position.
Always stand to the side of the
machine. Never work in front of or
behind the mower.

Risk of injury!
Blades are subjected to differing
degrees of wear depending on the
location and duration of use. If you
use the machine on sandy ground
or use it frequently under dry
conditions, the blade will be
subjected to greater loads and will
wear more quickly than the
average. A worn blade may break
off and cause serious injuries. The
instructions for blade maintenance
must therefore always be observed.
