W arning:
Some dust created by power sanding, sawing,grind-
ing,drilling, and other construction activities contains
chemicals known to the State of California tocause
cancer, birth defects or other reproductive harm. Some
examples of thesechemicals are:
•lead from lead-based paints,
• crystalline silica from bricks and cement and other
masonry products, and
•
arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies,depending on
how often you do this type of work. To reduce your
exposure to thesechemicals: workina well ventilated
area, and work withapproved safety equipment, such
as those dust masks that are specially designed to fil-
ter out microscopicparticles.
Usea vacuumcleaner for wood dust collection as
described in our manual whenever possible.
4. Grounding Instructions
In the event of amalfunction or breakdown,grounding
provides apath of least resistance for electric current
to reduce the risk of electric shock. This tool is
equipped withan electric cord having an equipment-
grounding conductor and agrounding plug. The plug
must be plugged intoamatching outlet that is proper-
ly installed and grounded in accordance withall local
codes and ordinances.
Do not modify the plug provided – if it will not fit the
outlet,have the proper outlet installed by aqualified
electrician.
Improper connection of the equipment-grounding con-
ductor can result in a risk of electric shock. The con-
ductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor.If repair or replacement of the
electric cord or plug is necessary,do not connect the
equipment-grounding conductor toalive terminal.
Check withaqualified electrician or service personnel,
if the grounding instructions are not completely under-
stood,or if in doubt as to whether the tool is properly
grounded. Use only 3-wire extension cords that have
3-prong grounding plugs and 3-pole receptacles that
accept the tool’s plug.
Repair or replace damaged or worncord immediately.
This tool is intended for useona circuit that has an
outlet that looks like the one illustrated in SketchAin
Figure 21.
The tool has agrounding plug that looks like the plug
illustrated in SketchAin Figure 21. A temporary
adapter, which looks like the adapter illustrated in
Sketches B and C, may be used toconnect this plug
toa 2-pole receptacle as showninSketchBif aprop-
erly grounded outlet is not available. The temporary
adapter should be used only until aproperly grounded
outlet canbe installed by aqualified electrician. The
green-colored rigid ear,lug, and the like,extending
from the adapter must beconnected toapermanent
ground suchas aproperly grounded outlet box.

7.1. Starting operation
Attention!
Before starting the band saw should beconnected to
adust extracting device.
Remove loose items and unnecessary work pieces
from the area before starting the machine
1. Connect the machine to the mains supply.
2.Switch the machine on with the power switch 4
(fig. 9 a)
7.1.1. Lockable Switch
Your MICRO Band Saw is equipped withalockable
switch (fig. 9 b): It allows you to make the saw child-
proof and makes any other unauthorized use impracti-
calas well. With the pulled-out pin like shown in the
sketch you cannot switch on the machine. Soanacci-
dental start-up will be impossible and unauthorized
use is prevented.
Anaccidental start-up of the machine by a child or
visitor could cause injury!
To save the machine, set the switch in position “Off”,
pull out the pin and disconnect the machine from the
power source.
To start the machine again and to operate the switch
in the usual way,just push the pin back into its open-
ing. Then you can reconnect the machine to the power
sourceand work with it.
7.2.Adjusting blade speed
Before starting work, adjust the appropriate speed for
the saw blade and the material.
Vernier adjustment of the band speed is possible with
the speed regulator 3 (fig. 9 a). Refer to the diagram
(5) for optimalband speed. The values are,however,
only reference values!
Generally applicable:
High band speed for thin materialand low band speed
for thick material.
7.3.Sawing
Mark the cut on the work piece. Never brake the band
speed by pushing too hard. The saw blade must ”cut
freely”, so the best results will beachieved. Incase of
vibrations adapt the band speed respectively.
7.3.1. Free-hand sawing
Press the work piece onto the work table,guide it
carefully and only with little force (fig.10 a). More
pressureagainst the work table,less pressureagainst
the saw blade.
Always avoid awkward operations and hand positions
wherea sudden slip could causeahand to move into
the blade. In thesecases use the push-stick (provided
with the saw, see fig. 10 b).
7.3.2.Sawing with miter guide
Attention!
Adjustments must only becarried out with the
machine switched off.
1. Adjust the desired angle on the miter guide.
2.Press the work piece lightly against the saw blade
(fig. 11).
7.3.2.1. Miter cuts
For miter cuts the working table canbe tilted toany
angle between 0°and 45°.
-9-

1. Loosen the clamping screw 1 (fig. 12)and tilt the
table to the desired angle.
2.Read the degrees on the scale (2).
3.Tighten the clamping screw (1).
7.3.3.Operation with the diamond saw blade:
For stones, ceramics,glass and fiberglass (42" x 7 / 64"
x 1 / 64 "). Adiamond saw band must only be used in
combination witha correctly mounted liquid coolant
system. Aliquid coolant kit is available by PROXXON
as anaccessory, see also fig. 13.Don´t work with the
diamond saw blade without appropriatecooling.
Note:
For operation withaliquid coolant system we recom-
mend the installation of a Coolant collection tray 3 (fig.
13). This Coolant collection tray is available as an
accessory by PROXXON.To seal the screwing holes
put the band saw on a rubber plateand fasten it with
the wood screws.
Attention!
To install the liquid cooling system follow the enclosed
instructions exactly!
7.3.3.1. Notes on the coolant:

7.3.3.2.Working withadiamond saw blade
Caution!
Cutting of radii smaller than 15 mm is not possible
with the diamond saw band (fig. 15).
Do not use diamond saw blades for metal,plastic
materials or wood!
Note:
Only sufficient cooling of the diamond saw blade
ensures better and quicker cutting of glass and ceram-
ics and prolongs the lifetime of the diamond band.
1. Guide the work piececarefully and only with little
force.
2.Close the shut-off valve 1 (fig. 14) after finishing
work or during breaks.
