Operation
8.2.2 0° position of worktable
To quickly reset to 0° position of the worktable, the table
is equipped with an adjusting screw (1). Use the
handwheel (2) to adjust the table's angle after releasing
the clamping lever.
Set the worktable to 0°. Check the setting by measuring
the angle between the worktable and the saw band with
a protractor. If needed, correct the table setting and re-
align the pointer on the scale.
Once the table is at an angle of precisely 90° to the saw
band, unscrew the adjusting screw (1) until it lies flush
against the table. Lock the screw with the nut.
Fig. 8: 0° position of worktable
8.2.3 Cutting height adjustment
To adjust the cutting height, release the clamping screw
(2) and turn the adjustment wheel (1) to set the saw
band guard to the desired height. After completing the
setting, tighten the clamping screw again.
Fig. 9: Cutting height adjustment
8.2.4 Saw band change
Step 1: Switch off the machine and disconnect the ma-
chine from the power supply.
Step 2: Open the front panel by turning the top and bot-
tom locking screws (1).
Step 3: Release the saw band clamp by actuating the
quick clamping lever (2).
Step 4: Carefully pull the used saw band off the rollers
and guide it through the slot in the table.
Step 5: Now place the new saw band on the two saw
band rollers in reverse order and centre with
respect to the rubbers supports.
Step 6: Finally, clamp the saw band again by actuating
the quick clamping lever (2); refit the table in-
sert and close the front panel.
Step 7: Adjust the saw run as described.
Fig. 10: Saw band change
IMPORTANT!
- The upper saw band guide must be set to reflect
the workpiece height. The upper saw band guide
must be 2-3 mm higher than the thickness of the
workpiece to be cut.
- Complete or check this setting before each cutting
action.
IMPORTANT!
Always wear gloves when changing the saw band.

Operation
HBS series | Version 2.03 15
8.2.5 Setting the band tension
Turning the adjusting screw (1) increase or reduces the
saw band tension via a spring. To change saw bands of
the same width, there is no need to change the basic
tension setting. The saw band can be released without
changing the basic tension setting via the standard
quick clamping system (2).
Fig. 11: Setting the band tension
8.2.6 Setting the saw band run
Step 1: Slowly turn the upper saw band pulley (1) clock-
wise by hand. The saw band should run cen-
trally on the rubber supports of the saw band
pulleys. If this is not the case, the upper saw
band pulley's angle of inclination must be ad-
justed.
Step 2: The screw (2) for adjusting the saw band run is
located at the rear centre of the machine. This
button is used to adjust the run. The saw band
run setting must be adjusted with the front panel
open.
Step 3: Turn the saw band pulley clockwise by hand to
check the saw band run through the sight pane.
Note that the saw blade run direction is top-
down. Loosen the lock nut (3) and correct the
saw band run by turning the adjusting screw
clockwise or anti-clockwise.
Step 4: Now check the saw band run on the lower saw
band pulley. It should lie flush against the rub-
ber support across its entire width. Correct the
run until the saw band is centered on the top
saw band pulley.
Fig. 12: Adjusting the saw band run
IMPORTANT!
The saw blades must be de-tensioned if you will not
be using the band saw for a longer period of time.
Denote this with
a label on the outside of the machine. Before you
recommission the machine,
you must re-tension the saw blades.
IMPORTANT!
- If the tension is too high, the saw band can break.
- Risk of injury!
- If the tension is too low, the driven saw band pulley
can slip, causing the saw band to stop.
NOTE!
Before the saw band run setting can be adjusted, it is
important to correctly adjust the blade tension...
IMPORTANT!
After competing the adjustment and before switch-
ing on, manually turn over the saw band pulley
through a number of revolutions to check whether
the saw band runs off the pulleys. If this is the case,
you need to re-adjust the saw band run.

Operation
8.2.7 Adjusting the saw blade guide
Step 1 Loosen the lock washer (1) and turn the two
ceramic guide discs (2) to move them up to
0.5 mm in front of the saw teeth. Then clamp
again.
Step 2 Loosen the clamping screw (3) and adjust the
support bearing (4) so that the saw band back
runs on the outer bearing ring.
The support bearing has the task of supporting the saw
blade in case of a rough cutting depth, and of ensuring
perfect cutting
Fig. 3: Adjusting the saw blade guide
8.2.8 Adjusting the saw band speed
Step 1 Disconnect the machine from the power sup-
ply.
Step 2 Release the drive belt by loosening the clamp-
ing screw on the motor.
Step 3 Now locate the v-belt on the desired v-belt
pulley
Step 4 Tension the drive belt again and then
retighten the clamping screw.
8.2.9 Swarf brush
The swarf brushes on the band saw require regular
maintenance. They are used to remove chips and dust
from the saw band pulleys' rubbers supports. They are
located behind the front panel. The chip brushes need
to be replaced when worn. Check them at regular inter-
vals before starting up the machine.
To adjust, release the fastening screws on the chip
brushes (1) and move the brushes to the correct posi-
tion. Then re-tighten the screws.
Fig. 5: Chip brush
IMPORTANT!
Only adjust the upper and lower saw band guides
after adjusting and checking the blade tension and
saw blade run.
IMPORTANT
The saw band will become useless if its teeth touch
the guide pins when the saw band is running. Cor-
rect adjustment of the upper and lower band guide
is thus important for a long saw band service life.
NOTE!
The saw band will become useless if its teeth touch
the guides when the saw band is running. Correct ad-
justment of the upper and lower band guide is thus
important for a long saw band service life.

breakage with band saw blades that are blunt and/
or have sharpening and tooth setting faults

18 HBS series | Version 2.03
Operation
For all cutting actions, move the upper band guide as
close as possible to the workpiece. This ensures the
best possible cut quality and operator safety. Always
guide the workpiece with both hands and keep it flat on
the band saw table to avoid the saw blade jamming.
Always use the rip fence or the mitre stop for all cutting
actions for which they can be deployed. This prevents
the saw band running out of the cut line, particularly in
case of working with the table at an angle. Plan the re-
quired work steps in advance. An old rule in crafts and
trades is "measure twice, cut once". It is better to com-
plete a cut in a single action than in several sections that
may require the workpiece to be pulled back.
In this case, switch off the band saw and wait for the
saw band to reach a standstill before pulling back the
workpiece. Note that the saw band causes a cutting kerf
and set the cutting width so that the cutting kerf is in the
cut-off part of the workpiece. Add an allowance if the
workpiece edge needs to be machined later on.
8.3 Mitre stop
The mitre stop is used to safely guide the workpiece
during cross-cutting or mitre cutting. For mitre cutting,
the mitre stop is equipped with a degree scale up to 45°
on both sides.
8.4 Rip fence
For long rip cuts, the workpiece is guided along the rip
fence. The rip fence can be adjusted to the desired cut-
ting width.
8.5 Rip cutting
Cutting along the grain of the wood is known as rip cut-
ting. You can cut freehand along a marked line, or along
a rip fence, thus achieving superior results. In case of
cuts at right angles (the table is at right angles to the
saw band), the rip fence is positioned to the left of the
saw band so that the workpiece can be guided safely
along the fence with your right hand.
In case of mitre rip cuts with the table at an angle, the rip
fence needs to be positioned to the right of the blade on
the side pointing down (if the workpiece allows this), in
order to prevent the workpiece slipping.
8.6 Cross cutting
Cross-cutting means sawing at right angles to the wood
fibre. This type of cut can also be performed freehand,
but for reasons of safety and precision, it makes more
sense to use a cross-cutting gauge. The cross-cutting
gauge can be set to 45° for mitre cuts.
In combination with an angled table, the operator can
thus perform double mitre cuts. Hold the workpiece
firmly against the fence on the cross-cutting gauge and
flat against the table. Pay attention to your fingers, par-
ticularly at the end of the cut; keep a safe distance to the
saw band. Small workpieces should be clamped. The
cross-cutting gauge can be equipped with an end stop
so that multiple workpieces can be cut to exactly the
same length. The end stop can also be used as a sup-
port when the table is angled.
8.7 Freehand cutting
The ease with which curves can be cut is one of the
most outstanding characteristics of a band saw. For
curved cutting select a saw band with a width that lets
you cut the smallest radii that occur in your workpiece.
For freehand cutting, you should work at a low feed
speed so that the saw band can follow the desired line.
Make sure that you do not push the workpiece laterally
out of the cutting line. This causes the saw band to run
off track and it can jam in the cutting kerf. It can be use-
ful to remove the excess material approx. 10 mm from
the cutting line. In case of very tight radii in which the
saw band can no longer cut perfectly, cuts at right an-
gles to the curve line and at a short distance apart can
help. When cutting the radius, the material drops off so
that the saw band cannot jam.
8.8 Sharpening and tooth setting of the saw
band
Professional maintenance of the saw bands is a major
prerequisite for achieving high cutting quality and pro-
ductivity.
If the cut is wavy after sawing, the saw band is blunt or
the teeth are not set correctly. After discovering that the
saw band is not working well, you need to sharpen the
saw band. If waviness of the cut occurs after sharpening
the saw band, you need to check and optimise the teeth
settings. The intervals between 2 sharpening actions
should not be too long; even if the cutting results are
fine, you should not use the saw band for longer than
approx. 1 hour. If impurities of the logwood were not re-
moved before cutting, you may need to sharpen the saw
band after the 1st cut.
As a general rule, the contact surface needs to be
ground far more than the face. When grinding, make
sure that the primary tooth profile is kept.
The tooth parameters, angle of rake and cross-set must
be tuned to match the type of wood (hardness). The
tooth height can be averaged and used for different
types of wood without any changes.

Saw band parameters:
To cut softwood that is frozen, use saw bands as for
harder wood.
Cutting hardwood with too great a rake angle:
the saw and wood shake, the machine is loud and
works unevenly. Change the saw band immediately.
Cutting softwood with too low a rake angle: even if the
saw band is sharp, waviness in the cut may occur.

DANGER!
Risk of fatal injury through electric shock!
There is a risk of fatal injury on touching live compo-
nents. Electrical components that are switched on
can perform uncontrolled movements and cause
injuries.
- Before starting cleaning and maintenance work, un-
plug the mains connector.
IMPORTANT!
- Never use solvents for cleaning plastic parts or
painted surfaces. This may cause the surface to
disintegrate and cause consequential damage.
ATTENTION!
Any chips that occur should be regularly removed
from the inside of the band saw. Before opening the
housing cover, switch off the machine and unplug
the connector. After opening, you can clean with a
brush or a vacuum cleaner. After completing the
work, remove chips and sawdust from the motor's
cooling openings.
NOTE!
Do not remove the chips with your bare hands. There
is a risk of injuries through sharp edged or pointed
chips!
NOTE!
Oil, grease and cleaning agent are harmful to the en-
vironment and must not be allowed to enter the
groundwater, or disposed of as normal domestic
waste. Dispose of these agents in an environmentally
friendly manner. Cleaning cloths soaked in oil, grease
or cleaning agent are highly flammable. Collect
cleaning cloths or cleaning wool in a suitable, closed
container and dispose of them in an environmentally
responsible manner - not as domestic waste!
