appropriate openings on one of the intermediate
struts (C) as far as the stop (Figure 13). Screw
the bottom cross struts (E) to the intermediate
strut (C) using two screws (L), washers (K) and
nuts (I) in each case, as shown in Figures 14 - 15.
On the same side of the base frame, slide the two
top cross struts (F) as far as the stop into the
appropriate openings on the side part (B) (Figure
16). Insert a corner bracing (Y) into each opening
on the side part (B). Note that each of the corner
bracings (Y) only fits on one side of the base
frame; this is the case when the openings on the
side part (B), the top cross struts (F) and the
corner bracings (Y) are positioned precisely on
top of each other (Figure 18).
Now screw together the top cross struts (F),
corner bracings (Y), side part (B) using two
screws (L), washers (K) and nuts (I) in each case,
as shown in Figures 18.
Insert the two base frame parts in such a way that
the bottom and top cross struts (E, F) are
positioned in the relevant openings on the side
part (B) and the cross strut (C) (Figure 19).
Screw the bottom cross struts (E) to the other part
of the base frame (Figure 20/1) as described
under 5.
Screw the top cross struts (F) to the other part of
the base frame (Figure 20/2) as described under
6.
Fasten the two tilt guards (26) to the cross struts
(C) with two nuts (I), washers (K) and screws (L)
in each case (Figure 21).
Secure the connection pieces (4) to the corners
of the machine frame with the screws (T). Place
the machine frame onto the mounted base frame.
Slide the screws (M) through the connection
pieces and secure them with the washers (J) and
nuts (I).
7.2 Assembling the saw table (Figures 24-27)
Slacken the screw heads (45) on the underside of
the saw table (15) and remove the chain bar (2)
from the saw table.
Lead the blade through the slot (a) in the
machine table and place the machine table on
the table guide so that the clamping screw (47)
fits through the mounting (48).
Screw the saw table tight with the locking grip
(18).
Place the chain bar (2) on the saw table (15) so
that the screw heads (50) slide into the guide
slots (51).
Check that the blade (25) runs freely and does
not touch the saw table.
To remove the saw blade guard, proceed in
reverse order.

7.3 Tensioning the blade (Figure 1,28)
CAUTION! Remove the tension from the blade
if the bandsaw is not going to be used for some
time. Be sure to re-tension the blade before you
start the machine.
Turn the tightening screw (9) for tensioning the
blade (25) in a clockwise direction.
The correct blade tension can be checked by
applying pressure to the side of the blade with
your finger, somewhere in the middle between
the two blade pulleys (7 + 8). You should only
be able to bend the blade (25) very slightly
(approx. 1-2 mm).
CAUTION! The blade may break if the tension
is too high. BEWARE OF INJURY! If the tension
is too low, the powered blade pulley (7) will spin
while the blade does not move.
7.4 Adjusting the blade (Figure 1,29-31)
CAUTION! The blade must be properly clamped
before the blade can be adjusted.
Undo the fasteners (13) and open the side cover
(12,14).
Turn the upper blade pulley (8) slowly in a
clockwise direction.
The blade (25) should run centrally on the blade
pulley (8).
If it does not, the angle at which the upper blade
pulley (8) tilts must be adjusted.
If the blade (25) runs more towards the rear of
the blade pulley (8), the setting screw (22) must
be turned in anticlockwise direction. Then turn
the blade pulley (8) slowly with the other hand to
check the position of the blade (25).
If the blade (25) runs towards the front edge of
the belt pulley (8), the setting screw (22) must
be turned in a clockwise direction.
After adjusting the upper blade pulley (8), check
the position of the blade (25) on the lower blade
pulley (7).
Again, the blade (25) should run in the middle of
the blade pulley (7). If it does not, the angle at
which the upper blade pulley (8) tilts must be
adjusted again.
The blade pulley must be turned several times
until the adjustment of the upper blade pulley (8)
has an effect on the position of the blade on the
lower blade pulley (7).
When adjustment has been completed, close
the side cover (12,14) again and secure it with
the fasteners (13).
