Maintenance And Inspection - Jet JWBS-14 Operating Instructions Manual

Tighten the placed sawblade
sufficiently.
Follow the scale on the back of the
machine.
Note:
When the band saw is not in use, the
blade tension can be reduced with the
quick blade tension lever on top of the
machine.
This will prolong the blade's life.
Also for blade changing it allows quick
blade tension release.
7.4 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.

Set the lateral guide elements so that
they contact the sawblade lightly.
The sawblade may not be pushed out
of place.
Bring the upper blade guide to a
distance of approx 0,5 cm to the
workpiece.
For your own safety, always set the
saw guide as close to the workpiece
as possible.
Turn the wheels by hand and inspect
the adjustments made.
Start the machine with care.
7.5 Folding the bandsaw blade
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.
