4.4 Saw band replacement and setting

Danger
Pull the power plug during all
service work.
To replace the saw band, proceed as follows:

Unscrew the cover 23 below and 22 above (fig.
2).

Loosen the cylinder screws 104 and remove the
band guard 145.

Loosen the band tension by turning the star
handle 6 to the left (fig. 5) until the saw band
can be removed. If necessary, clean the roller
coating of residual resin and chips.

First place the saw band with the tooth tips in
the direction of rotation on the lower roller
(arrow on the roller).

Then roll the saw band onto the upper roller and
tension it by turning the star handle to the right
6. The correct band tensioning is achieved when
the friction clutch in the star handle engages.

Manually move the band saw roller in the
direction of rotation. When doing so regulate the
the saw band by rotating the star handle screw
79b until the back of the saw band runs slightly
against the 2 band blushing stones 82 and the 2
slotted bolts 137.
If the saw band does not come into contact with the
upper or lower band blushing stone / slotted bolts
despite adjustment with star handle screw, adjust the
friction clutch in the star handle as follows:

Completely loosen the band tension by turning
the star handle 6 to the left.

Maintain the distance clearance "X" between the
base plate and any edge of the pivoting band
guide.

This distance must be reduced by at least 4 mm
(5/32 in.) but not more than 6 mm (15/64 in.)
when tensioning the saw band with the star
handle. If this distance is reduced more than 6
mm (15/64 in.) or less than 4 mm (5/32 in.), the
friction clutch in the star handle 6 must be
adjusted with a hexagonal spanner SW 6 (6
mm) (less tension to the left, more tension to the
right), until the friction clutch engages in the
tension range of 4 - 6 mm (5/32 to 15/64 in.).

Then set the band position with the handle
screw 79. Ensure that the back of the saw band
runs slightly against the band blushing stones
82 / slotted bolts 137.

To check, again loosen the star handle 6, and
re-tighten it until the friction clutch engages.
When doing so, check the reduction of the
clearance between the base plate and roller
housing to ensure that it is 4 - 6 mm (5/32 to
15/64 in.).
The band guard or covering above
and below must always be
attached.
Only saw bands with a width of 6 -
8 mm (1/4 or 5/16 in.) may be
used.
