Fig 18
In case of machine overload the motor overload cut-off will
react.
After appr.10 min of cooling the machine can be started
again.
6. Machine operation
Correct working position:
In front of the machine standing in the direction of cutting.
Cut preparation:
Bring the upper blade guide to a distance of approximately
3mm to the workpiece (Fig 19).
Fig 19
For your own safety, always set the saw guide as close to the
workpiece as possible.
Work only with a sharp and flawless sawblade.
Make sure blade is tracked and tensioned correctly.
Make sure blade guides are adjusted correctly.
If using the fence, move it into position and lock it to the
guide rail. Work only with rip fence securely locked in place.
For narrow shallow cuts on the rip fence, place the fence
profile into the horizontal position (Fig 13).
Turn on band saw and allow it to reach full speed.
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.
If possible, 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.
Near the cutting area use a push stick to feed, to prevent your
hands to come close to the saw blade.
Make relief cuts whenever necessary. A relieve cut is an extra
cut made through the waste portion of the wood.
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 20).
.
Fig 20
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 insufficient.
- Blade-teeth have asymmetric“set”

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
24).
Fig 24
The following table shows recommended saw blade pitch in
relation to workpiece thickness (Fig 25).

Fig 25
Tooth Shape:
The tooth shape effects the chip capacity and the feed rate.
The following table shows common tooth shapes (Fig 26):
Fig 26
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 27) is the most used for woodworking
blades.
Fig 27
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 28).
Fig 28
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 insert (D, Fig 29) and the slot handle
assembly (E).

Fig 29

Follow the scale (M, Fig 34).
Quick blade tension lever :
To operate the machine, place the quick blade tension lever
(Q, Fig 37) in the Full-Tension position (X).
Fig 37
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.
For blade changing, place the lever to the Fully-Released
position (Z).
Adjusting quick blade tension lever:
The quick blade tension lever (Q) allows you to adjust how
much tension is released when lever is used.
To adjust tension lever, remove the saw blade.
