Risk of injury.
Before tilting the mower, place it on
firm, level, 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.
Cleaning position RMA 443 C,
RMA 443 TC, RMA 448 TC:
● Stand to the right of the machine to tilt it
upwards.
● Move the upper handlebar (1) to the
lowest position (as far as the stop, the
detent lever does not engage in this
position). ( 9.4)
● Open discharge flap (2) with your right
hand and hold it open.
● Hold the console with your left hand as
shown and hold the discharge flap
open. At the same time, press detent
lever (3) with your thumb and hold
down.
● Hold the machine with the right hand on
the front handle and tilt it backwards
slowly until the handlebar is in contact
with the ground as shown.
● Release discharge flap (2) and detent
lever (3) and check that the machine is
stable.

● Lift the lawn mower up at the front and
place it in the cleaning position as
shown. Check that the machine is
stable.
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 on motor components, seals,
bearing points or electrical components
such as batteries or switches.
● First, remove accumulated clippings
using a stick.
● Remove dirt from the air slots on the
motor and the air ducts on the bottom of
the machine to ensure that the motor is
adequately cooled.
● If necessary, use a special cleaner
(e.g. STIHL special cleaner).

13.3 Electric motor and wheels

The electric motor is maintenance-free.
The wheel bearings are maintenance-free.

13.4 Battery

Maintenance interval:
Before each use
● Clean the battery with a damp cloth.
● Visually check that the battery is
undamaged. Batteries with identifiable
damage (e.g. cracks or escaping fluid),
must not be used.

13.5 Charger

Maintenance interval:
Before each use
Check electric cable for damage and
ensure that cooling air slots are free of dirt.

13.6 Checking blade wear

Maintenance interval:
Before each use
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 average. A
worn blade may break off and
cause serious injuries. The
instructions for blade maintenance
must therefore always be observed.
● Set the lawn mower onto its back into
cleaning position. ( 13.2)
● Clean the mowing blade (1).
● Use a slide calliper to measure the
blade thickness A at 5 points at least.
In particular, minimum thickness must
also be ensured in the area of the blade
wings.
● Check the blade width B in the area
marked in grey X at least 3 points
using a slide calliper.
Wear limits:
Blade thickness A: > 2 mm
Blade width B: > 55 mm
The blade must be replaced,
