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
out the plug.
7.1 Changing the sawblade
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 high rip cuts:
‐ use a wide sawblade (e.g. 10mm), coarse teethed.
For narrow curved cuts:
‐ use a narrow sawblade (e.g. 3mm).
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.
The sawblades may only be changed when the mains plug is
pulled!
To remove the blade:
Open the wheel covers.
Remove the table slot bolt (J, Fig 13).
Release the blade tension (A and I).
Open the upper and lower blade guards (Fig 14)
Remove the saw blade.

7.2 Folding the saw blade
A folded saw blade needs less space.
Always wear suitable gloves when handling sawblades.
Hold the band saw 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.
7.3 Blade tracking adjustment
Blade tracking shall never be performed when the machine is
running.
‐ Disconnect band saw from power source.
‐ To check the blade tracking, rotate drive wheel by hand in
clockwise direction. View blade through tracking window.
‐ The sawblade must run on the centre of the rubber tyres (Fig
15).
‐ With the knob (K, Fig 13) on the back of the machine, the
blade tracking can be adjusted.
‐ When blade is tracking properly (Fig 15), secure position by
tightening nut.
7.4 Blade tension adjustment
Blade tension is set with the blade tension knob (A, Fig 13).
Tighten the placed sawblade sufficiently.
Quick blade tension lever :
To operate the machine, the quick blade tension lever (I, Fig
13) must be in the "tensioned" up position.
Note:
When the band saw is not in use for a longer period of time,
place the quick blade tension lever to the lowered position;
releasing the blade tension will prolong the blade's life.
7.5 Blade guide adjustment
Blade guide adjustment shall never be performed when the
machine is running.
