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.
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.
Bring the upper blade guide to a
distance of approx 5mm to the
workpiece.
For the authorized use of the
machine observe the appendix A

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 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. 30mm),
coarse teethed.
For narrow curved cuts:
- use a narrow sawblade (e.g. 6mm).
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!
7.2 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 6).
With the knob on the back of the
machine the blade tracking can be
adjusted.
