6.6 Connecting the vacuum cleaner (fig. 4)
1.Place the vacuum hose 1ofthe vacuum cleaner in the connecting
piece 2.
2. Switch on the vacuum cleaner before sawing so thatthe sawdust is
vacuumed
and the suction device does not get blocked. Forpracti-
cal reasons, the PROXXON suction control device is recommended.

Sawblades
Caution!
Always remove the mains plug before performing the activities
described here.
6.7.1 Clamping in the sawblade (fig. 5a and 5b)
Standard blades with cross pins and hand(leaf)blades without cross
pin can be clamped into the sawblade mount.
Replace damaged or worn sawblades immediately.They represent
asafety risk and worsen the work result. The best cutting perform-
ance and precision can only be achieved with perfect sawblades.
Use PROXXON original sawblades and carefully select suitable saw
blades for the intended purpose and material to be cut.With Proxxon,
there are also various fine toothings, flatand round blades, and some
with and without cross pin. Youwill find suggestions in these in-
structions.
6.7.1.1 Sawblades with cross pin (fig. 5a)
Sawblades with cross pin are particularly suitable for working with
manyclosed inside cuts. The sawblade can be quickly and comfort-
ably removed from the upper mount, looped through the work piece
and repositioned. Youwill find more precise information in the sec-
tion "Inside cuts".
Caution!
Sawblades with cross pins may only be hung in position. Do not
clamp the sawblades with the cross pin additionally by means of the
cheese-head screws. Risk of fracture!
1. The the rotaryknob 1(Fig. 6) for sawblade tensioning to the left
until the sawblade is loose.
2. Place sawblade 1with the toothing pointing downwards through
the table opening 2and fit in the bottom mount 3.
3. Press lightly on the top arm 5and fit blade in the upper mount 6,
see fig. 5a).
4. Release arm and by turning the rotaryknob 1(Fig. 6) to the right,
set the sawblade tensioning.
5. If required, finely adjust the sawblade clamp as described under
6.7.2.
6.7.1.2 Sawblades with flat ends
(hand or leaf sawblades, see fig. 5b)
1. Turn rotaryknob 1(Fig. 6) for sawblade tensioning to the left until
the sawblade is loose.
2. Place sawblade 1with the toothing at the bottom through the
table opening 2and fit in the bottom mount 3.The cheese-head
screw 4may not be tightened! Then clamp the blade in the
mount by tightening the cheese-head screw 4with the supplied
Allen
key with Tgrip 5. Caution: Make sure thatthe blade is
clamped really far forward! This is where the clamping force is
at its greatest.
3. Press lightly on the top arm 6, introduce the sawblade into the
upper holder 7and tension in the same way.
4.
Releasethe arm and set the sawblade tensioning by turning the
rotaryknob 1(Fig. 6) to the right.
5. If required, adjust the sawblade clamp as described under 6.7.2
6.7.2 Finely setting the correct sawtensioning (fig. 6)
Correct sawtensioning is an essential factor for aclean work result.
This must, therefore, be carefully set. If over or undertensioned, the
sawblade can lightly crack. Turn knurled button 1toset the ten-
sioning. If the button is moved to the right (clockwise), the sawblade
is more tightly tensioned. If it is turned to the left (anticlockwise) the
blade is loosened.
Acorrectly tensioned blade sounds aslight tone if "plucked" like a
string.
6.7.3 Removing sawblade (fig. 5a and 5b)
6.7.3.1 Sawblades with cross pin (fig. 5a)
1. The the rotaryknob 1(Fig. 6) for sawblade tensioning to the left
until the sawblade is loose.
2. Presstop arm 5slightly down so thatthe sawblade 1can be
released from thetop mount 6. Take out sawblade.
3. Take out sawblade from bottom mount 3and remove through
table opening 2.
6.7.3.2 Sawblades with flat ends (fig. 5b)
1.The the rotaryknob 1(Fig. 6) for sawblade tensioning to the left
until the sawblade is loose.
2.Open wingnut 8, the sawblade 1releases from the top mount 7.
3.
Open cheese-head screw 7with the Tgrip Allen key 5, release saw
blade from the lower mount 3and remove through the table opening.
7Working with the saw
7.1 General information for working with mechanical fret saw
The mechanical fret sawispredominantly amachine for sawing
curves and precise sections. Atypical application is shown in fig. 7.
The work piece must be carefully guided by the operator. Note: Me-
chanical fret saws are normally operated without length stop, as the
sawblade loses its line íf forced in, particularly in the grain of wood.
Please note thatthe sawblade only saws in reverse motion in the di-
rection in which the teeth point.
Forgood results, please note the following points:
–When sawing, press the work piece onto the work plate (fig. 7),
guide by feeling and with little power; more pressure on the work
plate, less pressure against the sawblade.
–Make sure thatthe work piece is lying properly on the sawtable
(nor burrs or sawdust)
