Move the mount (49) of the guide bearings (29)
so that there is a gap of approx. 1 mm between
the front edge of the guide bearings (29) and the
gullet of the blade in front.
Re-tighten the screw (40).
IMPORTANT! The blade will be rendered
useless if the teeth touch the guide bearings
while the blade is running.
Undo the screws (38)
Move the guide bearings (29) towards the blade
so that there is a gap of max. 0.5 mm between
the guide bearings (29) and the blade (25). (The
blade must not jam.)
Re-tighten the screws (38).
Turn the lower blade pulley (7) several times in
clockwise direction.
Check the setting of the guide bearings (29)
again and re-adjust if necessary.
7.6 Adjusting the upper blade guide (11)
(Fig. 1/32)
= Undo the fixing handle (20).
= Lower the blade guide (11) as close as possible
to the workpiece to be cut (the gap should be
approx. 2-3 mm).
= Re-tighten the fixing handle (20).
= Check the setting before each cut and re-adjust
if necessary.
7.7 Adjusting the saw table (15) to 90°
(Fig. 26,33)
= Move the upper blade guide (11) to the top.
= Undo the fixing handle (18).
= Set the angle (d) between the blade (25) and the
table (15).
= Tilt the saw table (15) by turning it so that the
angle between it and the blade (25) is precisely
90°.
= Re-tighten the fixing handle (18).
= Undo the screw (52) of the pointer of the dial
scale (16), set the pointer to exactly 0° and
tighten the screw (52) again.
= No bracket included.
7.8 Selecting the blade
The blade supplied with the bandsaw is designed for
all-purpose use. When you select a blade you should
have regard to the following criteria:
=
Use a narrow blade to cut tighter radii than you
can with a wider blade.
=
Wide blades are used to saw straight cuts. This
is particularly important in cutting wood because
the blade has a tendency to follow the grain of
the wood and thereby deviate easily from the
cutting line.
26
=
Finely toothed blades provide smoother cuts but
are slower than coarse blades.
Important: Never use warped or lacerated blades!
7.9 Replacing the blade (Figure 1,34)
=
Move the blade guide (11) into a position
approximately half way between the table (15)
and the machine frame (24).
=
Undo the fasteners (13) and open the side cover
(12).
=
Remove the chain bar (2).
=
Turn the tightening screw (9) anti-clockwise to
remove the tension from the blade (25).
=
Remove the blade (25) from the blade pulleys
(7,8) and take out through the slot in the table
(15).
=
Fit the new blade (25), aligned centrally on the
blade pulleys (7,8).
=
The teeth of the blade (25) must point
downwards in the direction of the table.
=
Tension the blade (25) (see 7.2).
=
Close the side cover (12) again.
7.10 Changing the rubber tires on the blade
pulleys (Fig. 35)
After a certain time the rubber tires (3) on the blade
pulleys (7,8) will get worn by the sharp teeth of the
blades and must be replaced.
= Open the side cover (12).
= Remove the blade (25) (see 7.7).
= Lift the edge of the tire (3) with a screwdriver (P)
and remove from the blade pulley (8).
= Repeat for the lower blade pulley (7).
= Fit the new rubber tire (3), mount the blade (25)
and close the side cover (12) again.
7.11 Changing the table insert (Figure 36)
To prevent increased likelihood of injury the table
insert (17) should be changed whenever it is worn or
damaged.
7.12 Extractor socket (Fig. 1-2)
The bandsaw is equipped with two extractor sockets
for extracting sawdust and chips. The equipment may
only be used with the extractor function. The
extraction channels must be checked and cleaned at
regular intervals.
Make sure that the extractor connection which is not
in use is always sealed off with the supplied caps.
7.13 Adjusting the blade speed
(Fig. 45)
The bandsaw can be operated at two blade speeds.
To change the position proceed as follows:
