Application
The
full
tightening
or
slackening
action
provided
depends
on
the
time
during
which
the
percussion
mechanism
is
allowed
to
run.
Max.
tightening
torque
is
the
sum
of
the
torque
applied
by
each
stroke.
1
According
to
the
type
of
screwed
connection
the
max
.
torque
will
generally
represent
approx.
100
single
torque
strok-
es,
which
are
applied
in
5
seconds.
Available
max.
torque
in
normal
service
is
500
lbs.
ft
(70
mkg)
(see
diagram).
There
is
no
point
in
applying
the
tool
for
longer
than
5
seconds
since
the
torque
will
not
increase
any
further,
while
the
tool
head
will
appreciably
heat
.
Overheating
will
lead
to
increased
wea
r
of
all
percussion
components
and
excessive
lubricant
consumption.
6.
Maintenance
and
Lubrication
This
will
depend
on
the
duty.
The
following
instructions
are
for
continuous
use
in
8-hour
day
with
actual
tool
running
time
representing
20°
/o
of
total
duty
period.
Grease
once
per
week
at
the
lubricating
nipple
(58)
.
Percussion
mechanism
and
gearing
should
be
com
pletely
cleaned
of
old
grease
at
least
every
400
duty
hours
(approx.
8
weeks).
For
this
purpos
e
unscrew
four
screws
(64).
remove
outer
bear-
ing
(57)
and
lift
percussion
mechanism
out
of
intermediate
bear-
ing
without
dismantling
it.
Then
apply
plenty
of
grease
Sst
1
to
the
impact
faces
of
parts
(55)
and
(56),
as
well
as
to
planetary
gearing
(80
g/2
oz).
Reference
for
tube:
MZ
60-3/Sst
1 (90 g/3 oz).
After
900
hours
rinse
ball
bearings
in
clean
solven
t
and
pack
with
fresh
grease
(Sst
1)
.
The
space
between
inner
an
d
outer
rings
is
to
be
one
third
filled
with
grease
in
order
to
prevent
overheating
of
th
e
bearings.
To
avoid
overheating
and
to
ensure
adequate
lubrication
at
the
same
time,
it
is
important
to
pack
the
gearing
with
the
grades
and
quantities
of
grease
listed
in
the
table
below:
No
claims
can
be
entertained
for
damage
due
to
n
eg
ligent
main-
tenance
and
inadequate
lubrication
.
If,
after
long
duty,
the
impact
dogs
of
percussion
piston
(55)
and
tool
holder
(50)
are
worn
th
ey
must
be
reground
so
that
the
mechanisms
should
be
dismantled
according
to
the
instructions.
We
recommend
our
Fein
Ser
vice
Stations
to
carry
out
all
repair
work
of
this
kin
d
quickly
and
expertly.
Please,
take
care
that
all
electric
parts
are
only
cleaned
dry
.
