Maintenance and care
Dangers during maintenance!
During all maintenance work:
■
Switch off the engine and remove the ignition
key.
■
Remove the spark plug connector(s).
■
Any protective devices removed for mainte-
nance must be reinstalled after finishing the

DANGER OF BURNS:
Work on the appliance only when it has
cooled down. The engine, gearbox and si-
lencer get very hot!
■
DANGER OF LACERATIONS:
When working on the cutting tools, pay atten-
tion to the sharp blades. In the case of cutting
tools with multiple blades, moving one cutting
tool can cause another cutting tool to move
as well.
■
Use only OEM spare parts when replacing
parts.
■
If in doubt, always visit a specialist workshop
or contact the manufacturer.
