Maintenance
and
repair
work
An
unexpected
jet
of
water
can
cause
serious
injury.
Prior
to
any
maintenance
or
repair
work
therefore
ensure
that
the
water
supply
is
securely
turned
off.
8.1
Maintenance
After
one
year
of
use,
tighten
the
M6
flange
screws
(8
of
them)
using
a
10mm
box
spanner
to
ensure
that
the
sprinkler
module
is
fixed
firmly
in
place.
Tightening
torque
9
+1
Nm.
Clean
out
the
inside
of
the
sprinkler
housing
using
an
industrial
vacuum
cleaner
or
similar
(as
necessary).
Cut
sprinkler
housing
free
of
any
overgrowing
grass.
It
makes
sense
to
carry
out
these
jobs
prior
to
spring
commissioning.
Regularly
check
that
the
sprinkler
is
flush
with
the
surface,
especially
in
the
case
of
natural
grass.
