CLEANING
Keep
your
machine
clean.
Cleaning
the
machine
on
a
regular
basis
will
help
detect
and
solve
potential
problems
before
they
cause
damage
to
the
machine.
Most
importantly,
check
and
clean
the
tool
plate
connections,
vacuum
hoses,
water
tank
and
the
Propane
installation.
CHECK
HOURLY
BONNET
FILTER
‐
Make
sure
the
bonnet
air
filter
atop
the
engine
is
clean.
It
should
be
changed
hourly
and
thoroughly
cleaned
before
reuse.
The
same
for
the
recoil
dust
filter.
If
neglected
the
engine
will
overheat
and
carbon
monoxide
emissions
will
elevate.
CHECK
DAILY
After
operating
the
Lavina®
S
machine,
the
operator
should
conduct
a
visual
inspection
of
the
machine
during
cleaning
the
whole
machine.
Any
defect
should
be
solved
immediately.
Check
oil
level
daily.
Tool
holders:
Buffers
and
spiders
are
consumables
and
must
be
visually
checked
daily
and
replaced
if
needed.
See
flanges
or
discs
are
mounted
locked
well
in
place
The
key
lock
holders
(butterflies)
should
be
also
checked.
Check
the
rubber
buffers
and
fixing
of
the
holders.
The
flange
holding
the
buffers
(Fig.8.1
1)has
to
be
firmly
fixed
to
the
unit.
A
gap
seen
there
means
that
there
are
loose
screws
fixing
the
holder.
The
screws
have
to
be
tightened
immediately
for
safe
operation.
Working
with
loose
screws
on
the
holder
could
also
cause
bad
damage
on
the
machine.
Tightening
fo rce
of
the
screws
has
to
be
25...30N.m
(18...22
ft/lbs).
It
is
very
important
to
regularly
check
the
screws(Fig.8.1
2),that
fix
the"Quickchange"
holder
to
the
safety
part,
so
that
holder
will
not
fly
away
if
the
buffers
get
damaged.
“Quickchange”
sleeves
should
be
clean.
The
tension
of
the
planetary
belt
can
be
daily
checked
by
moving
the
main
head
and
feeling
the
resistance
of
the
moving
pulleys,
if
the
belt
slips
tension
immediately,
like
described
in
the
chapter
Troubleshooting
.
CHECK
AND
REPLACE
AFTER
THE
FIRST
8
WORKING
HOURS
Replace
the
oil
in
the
engine
after
the
first
8
hours
work,
according
to
the
instructions
of
the
engine
manufacturer.
Always
use
30HD
or
10W30
engine
oil
with
all
of
the
following
ratings:
SF,
SG,
and
CC
CHECK
AND
REPLACE
AFTER
THE
FIRST
15
WORKING
HOURS
Check
the
belt
tension
after
15
hours
working
with
the
machine.
The
bottom
cover
has
a
control
cover
(Fig.
8.2)
that
allows
fast
and
easy
control
and
correction
of
the
belt.
It
is
recommended
to
check
the
tension
of
the
belt
after
the
first
15
hours
and
to
tighten
if
necessary.
For
the
correct
tension,
see
TROUBLESHOOTING
“mounting
the
belt”.
Every
time
you
open
the
control
cover,
mount
back
all
the
screws
with
washers.
CHECK
AND
REPLACE
EVERY
50
WORKING
HOURS
Change
engine
oil,
while
changing
check
for
leakage
of
engine
oil
at
the
various
seals.
The
hour
meter
will
blink
between
48
‐
52
hours
as
a
reminder.
/"Engine
