Operation - Scheppach HBS20 Traduction Des Instructions D'origine

• Check the setting of the top guide pins (38) again
and adjust if necessary.
• If necessary, adjust the top support bearing (36)
(9.4.1).
9.4.4. Adjusting the bottom guide pins (46)
(Fig.7+8)
• Disassemble saw table (7)
• Undo screw for bottom retainer (43) (Allen key,
size 5)
• Move bottom retainer (47), bottom guide pins (46),
until the front edge of the bottom guide pins (46)
is approx. 1 mm behind the tooth base of the saw
band.
• Retighten screw for bottom retainer (43).
• ATTENTION! The saw band will be unusable if the
teeth touch the guide pins with the saw band run-
ning.
• Undo Allen screws for bottom guide pins (45).
• Slide the two bottom guide pins (46) sufficiently far
in the direction of the saw band that the distance
between the guide pins (46) and Bandsaw blade
(21) is max. 0.5 mm. (Saw band must not jam)
• Retighten Allen screws for bottom guide pins (45).
• Turn the bottom saw band roller (8) a few times in
a clockwise direction.
• Check the setting of the bottom guide pins (46)
again and adjust if necessary.
• If necessary, adjust the bottom support bearing
(42) (9.4.2).
9.5. Adjusting the top saw band guide (5) (Fig. 9)
• Undo locking handle for saw band guide (23).
• Turn the adjustment handle for the saw band guide
(22) to lower the saw band guide (5) as closely as
possible (distance approx. 2-3 mm) over the ma-
terial to be cut.
• Retighten locking handle (23).
• Check the setting before every cutting process and
adjust if necessary.
9.6. Adjusting the saw table (7) to 90° (Fig. 10+11)
• Set the top saw blade guide (5) fully upwards.
• Undo locking handle (20) and wing nut (31) (Fig. 2).
• Place the angle bracket between the Bandsaw
blade (21) and saw table (7). Angle bracket not
included in the scope of supply.
• Tilt the saw table (7) by turning, until the angle to
the Bandsaw blade (21) is precisely 90°. If the saw
table is already on the screw (49) and a 90° angle
cannot be set, undo the nut (50) and shorten the
screw (49) by turning in a clockwise direction.
• Retighten the locking handle (20) and wing nut (31).
• Also undo the nut (50).
• Adjust the screw (49) sufficiently that the saw table
touches the underside.
• Retighten the nut (50) to fix the screw (49) in position.
9.7. Which saw band to use
The saw band supplied in the band saw is intended
for universal use. The following criteria should be
considered when selecting the saw band:
• It is possible to cut tighter radii with a narrow saw
band than with a wide saw band.
• A wide saw band is used if a straight cut is re-
quired. This is important in particular when cutting
wood. The saw band has a tendency to follow the
wood grain and therefore deviates easily from the
desired cutting line.
• Fine-toothed saw bands cut more smoothly, but
also more slowly than coarse saw bands.
Attention: Never use bent or torn saw bands!
9.8. Replacing the saw band (Fig. 1a+1b+14)
• Set the saw band guide (5) at approx. half height
between the saw table (7) and machine frame (15).
• Undo the cover locking mechanisms (10) and open
the side covers (11).
• Remove U-reinforcement (34) as described in 9.1.
• Relieve the Bandsaw blade (21) tension by turning
the clamping screw (1) anti-clockwise.
• Remove the Bandsaw blade (21) from the saw band
rollers (2+8) and through the slot in the saw table (7).
• Place the new Bandsaw blade (21) centrally on
both saw band rollers (2+8). The teeth of the Band-
saw blade (21) must point downwards in the direc-
tion of the saw table (Fig. 6).
• Tension the Bandsaw blade (21) (see 9.2)
• Close the side cover (11) again.
• Re-install the U-reinforcement (34).
9.9. Replacing the table insert (Fig. 13)
In case of wear or damage, the table insert (6) must be
replaced; otherwise there is an increased risk of injury.
• Remove the worn table insert (6) by lifting it up
and out.
• Installation of the new table insert takes place in
reverse order.
9.10. Extraction nozzle (Fig. 1b)
The band saw is equipped with an extraction nozzle
(19) 40 mm for chips.
Only operate the device with a suitable extraction
system. Check and clean the suction channels at
regular intervals.
9.11. Push Stick retainer (Fig. 12)
The Push Stick retainer (48) is pre-mounted on the
machine frame. If unused, the Push stick (26) must
always be stowed in the Push Stick retainer.

10. Operation

10.1 On/Off switch (12) (Fig. 15)
• To turn the machine on, press the green button „I".
• To turn the machine off again, press the red but-
ton „0".
• The band saw is equipped with an undervoltage
switch. With a power failure, the band saw must
be switched back on again.
10.2. Parallel stop (Fig. 16)
• Press the clamping bar (25) of the parallel stop
(24) upwards
• Slide the parallel stop (24) left or right of the Band-
saw blade (21) on the saw table (7) and set to the
desired measurement.
• Press the clamping bar (25) down to fix the par-
allel stop (24) in place. In order to increase the
clamping force of the clamping bar (25), rotate it
clockwise until the parallel stop is sufficiently fixed
in place.
• Make sure that the parallel stop (24) always runs
parallel to the Bandsaw blade (21).
