5.4 Starting operation
You can start the machine with the green on button. The red
button on the main switch stops the machine.
6. Machine operation
Correct working position:
In front of the machine standing in the direction of cutting.
Workpiece handling:
Hands placed flat on the workpiece outside the cutting area.
Feed the workpiece towards the saw blade in the direction of
the saw line, and cut as required by turning to follow the line
drawn. Push the workpiece steadily forward; complete the cut
as a single movement. Do not draw the workpiece back, as
this could cause the sawblade to run off its wheels.
Support long and wide workpieces with helping roller stands.
Operating hints:
Work only with a sharp and flawless sawblade.
Near the cutting area use a push stick to feed.
Bring the upper blade guide to a distance of approx 0,5 cm to
the workpiece.
Use a feeding template to safely guide small and narrow
workpieces.
Use a suitable wedge to prevent round timber from turning
under the pressure of the cut
Blade Drift:
Blade drift is a frequent problem on rip cuts and during
resawing.
Blade drift may occur when the fence is being used, the blade
begins to wander off the cutting line (Fig 6).
.
Fig 6
Blade drift can be caused by a number of factors.
- The saw blade follows the grain
- The saw blade is dull.
- Blade guides not adjusted correctly.
- Blade tension unsufficient.
- Blade-teeth have asymmetric“set”
Resaw guide:
The resaw guide allows you to compensate blade drift.
The feed direction can be lined up to follow the cut.
For resawing attach the post (A, Fig 7) to the fence with the
lock knob (B). Position the post so that it is centered with the
blade teeth.
Fig 7
Auxiliary fence for rip fence:
For your own safety always set the upper saw guide as close
to the workpiece as possible.
For narrow shallow cuts on the rip fence a self-made auxiliary
fence (E, Fig 8) made of cutable material ( e.g. wood, plastic,
aluminium) must be used.
Length same as rip fence.
Fig 8
Mitre gauge:
Place the mitre gauge in the table
T-slot.
If the mitre gauge is not square loosen the lock knob (C, Fig
7) and adjust the pointer (D).

7. Setup and adjustments
General note:
Setup and adjustment work may only be carried out after
the machine is protected against accidental starting by
pulling the mains plug.
7.1 Saw blade selection
The sawblade has to meet the technical specification.
Choose a suitable sawblade, according to the cutting
operation and according to the material to be cut.
For a high rip cut:
- use a wide sawblade, coarse teethed
(e.g. 20mm, 3 T/”)
For a narrow curved cut:
- use a narrow sawblade
(e.g. 3mm, 14 T/”).
Pitch:
The pitch should not be smaller than necessary, as the feed
speed is reduced if there are too many teeth working on the
workpiece simultaneously, which causes the saw blade to
wear more quickly.
Ideally, 3 to 12 teeth should be in action at the same time (Fig
9).
Fig 9
The following table shows recommended saw blade pitch in
relation to workpiece thickness (Fig 10).
Fig 10
Tooth Shape:
The tooth shape effects the chip capacity and the feed rate.
The following table shows common tooth shapes (Fig 11):
Fig 11
A- Regular tooth:
The most common used tooth shape. 0° rake angle.
Suited for cut-off and contour sawing of most materials. For
cutting materials where a fine cut is required.
B- Skip tooth:
Widely spaced teeth, to prevent clogging. 0°rake angle.
For resawing and ripping thick stock, especially soft woods.
C- Hooked tooth:
Large teeth and a positive rake angle, for aggressive, faster
cutting.
For resawing and ripping thick stock, especially hard woods.
D- Variable tooth:
Variable tooth shape and spacing produces smooth cuts and
dampens vibrations.
Set:
Saw teeth are bent out of the plane of the saw body, resulting
in a wide cut in the workpiece.
This helps reduce friction and allows curve cuts).
The alternate set (Y, Fig 12) is the most used for woodworking
blades.
Fig 12
X- Raker set
Y- Alternate set
Z- Wavy set
Blade width:
Use a possibly wide blade, except for contour cutting.
The following table shows relation between saw blade width
and smallest cutting radius (Fig 12).
Fig 13
Blade material:
- carbon steel
- alloy steel
- bimetal (HSS teeth welded onto alloy steel blade body)
-carbide tipped.
7.2 Changing the sawblade
Check sawblade for flaws (cracks, broken teeth, bending)
before installation. Do not use faulty sawblades.
The sawblade teeth must point in cutting direction (down)
Always wear suitable gloves when handling sawblades.
To remove the blade:
Open the wheel covers.
Remove the table pin (F, Fig 14) and the table insert.
Fig 14
Release the blade tension by operating the quick blade
tension lever (Q, Fig 16) and by turning the blade tension
handwheel (A) on top of the machine.
After the new saw blade is installed, tighten the sawblade
sufficiently. Follow the scale (S).
7.3 Blade tracking adjustment
Blade tracking shall never be performed when the machine is
running.
The sawblade must run on the centre of the rubber tyres (Fig
15.
Fig 15
With the knob (T, Fig 16) on the back of the machine the
blade tracking can be adjusted.
Fig 16
7.4 Blade tension adjustment
Quick blade tension lever:
Place the quick blade tension lever (Q, Fig 16) in the
“tensioned” position (X).
Set the blade tension by rotating the handwheel (A).
Tighten the sawblade sufficiently. Follow the scale (S).
Note:
When the band saw is not in use, place the quick blade
tension lever to the Partial-Tension position (Y),
this will prolong the blade’s life.
Also for blade changing this allows quick blade tension
release.
7.5 Blade guide adjustment
Blade guide adjustment shall never be performed when the
machine is running.
Position the guide assembly forward/ backward so that the
teeth keep a distance of appr. 2mm to the guide elements.
Secure the back guide roller so that the distance to the saw
blade is 1mm (Fig 17).
Fig 17
Set the lateral guide elements so that they contact the
sawblade lightly.
The sawblade may not be pushed out of place.
Test run:
Turn the wheels by hand and inspect the adjustments made.
Start the machine with care.
Workpiece setup:
Bring the upper blade guide to a distance of 0,5cm to the
workpiece (Fig 18).
Fig 18
For your own safety, always set the saw guide as close to the
workpiece as possible.
7.6 Folding the bandsaw blade
A folded saw blade needs less space.
Wear heavy gloves.
Hold the bandsaw blade in one hand. Let it hang down
vertically and hold it to the floor with a foot. Turn your hand
through 360°, a complete circle, as you move it down towards
the floor
(Fig 19).
