Completely
remove
the
tensioning
device
(Fig.
9.5.1).
Make
2
signs
on
the
dismounted
belt
that
are
exactly
10cm
from
each
other
(belt
without
tension)
(Fig.9.5.2).
The
purpose
is
to
measure
10.2
cm
on
the
belt
when
tensioned.
ATTENTION:
NEVER
“OVER”
TENSION
THE
BELT,
THE
BELT
WILL
BE
DAMAGED
AND
IT
WILL
NEVER
RECOVER
FROM
ITS
ORIGINAL
TENSION
Mount
the
belt
back
around
the
planetary
pulley;
see
that
the
belt
is
behind
the
driving
pulley
(Fig.9.5.3).
Put
the
belt
around
the
left
roller
of
the
tensioning
device
(Fig.9.5.4).
Put
the
tensioning
device
back
in
place
and
pull
the
belt
from
the
roller
on
the
right
side
(Fig.9.5.5).
Put
the
belt
around
the
driving
pulley
(Fig.9.5.6).
Begin
to
tension
until
the
previous
10cm
measurement
equals
10.2cm
(Fig.9.5.7
and
Fig.9.5.8).
Tighten
the
tensioning
device
while
turning
the
bolt
and
moving
the
planetary
head
so
the
belt
can
slide
(Fig.
9.5.8).
Do
not
forget
to
lock
the
tensioning
device
(Fig.9.5.9).

CHECKING
THE
TENSION
OF
THE
BELT
Open
the
checking
cover
to
reach
the
belt
and
tension
device
(Fig.9.6.1).
While
tensioning,
be
sure
to
regularly
check
the
tension.
Push
the
belt
down
with
a
pressure
of
71N.
This
is
approximately
7
kilograms
or
15
pounds;
with
this
pressure
the
belt
should
move
3.5
‐
4
mm
or
1/8”.
It
is
recommended
that
the
tensioning
of
the
belt
be
measured
with
Optikrik
II
Device
(Measuring
range:
500
‐
1400
N)
(Fig.9.6.2).
The
original
pressure
P=1400
N
and
after
working
awhile
is
P=1100
N.
ATTENTION:NEVER
“OVER”
TENSION
THE
BELT,
THE
BELT
WILL
BE
DESTROYED
AND
IT
WILL
NEVER
RECOVER
ITS
ORIGINAL
TENSION
Loosen
the
contra
nuts
(Fig.9.6.3),
lightly
loosen
the
three
bolts
of
the
tension
device
(Fig.9.6.4),
and
adjust
the
tension
with
the
nut
seen
in
(Fig.9.6.5).
When
the
right
tension
is
reached:
close
the
contra
nuts
and
the
three
bolts
of
the
support.
Reassemble
in
the
same
manner.
PLEASE
MAKE
SURE
YOU
CHECK
THE
TENSION
OF
THE
BELT
AFTER
THE
FIRST
15
HOURS
OF
OPERATION
