Machine Features; Additional Handle - Festool GD 320 Manual De Instrucciones

- With drilling machines with a torque of more
than 55 Nm, it is necessary to use always the
extension piece for the additional handle.
- The material must always rest on a stable pad,
and be secured against turning over and slip-
ping.
- The tilting drilling stands (GD 460 A) must be
always secured against shifting when drilling
orifi ces at an angle. For this purpose, we rec-
ommend that you employ clamps (accessories).
- During work, stand always in a safe and stable
position.
- During all the tasks that serve for the prepara-
tion, assembly, re-setting, adjustment, replace-
ment of the drills or maintenance and care, it is
always necessary to pull the plug of the drilling
machine out of the mains.

6 Bringing the Stand into Operation
6.1 Adjustment of the guiding disk
Choose the corresponding orifi ce in the guiding
disk in compliance with the required drill diam-
eter, and insert it into the axis of the drill (1.1):
 turn the rotary button (3.1) to the left through
5 revolutions approximately,
 lift the guide disk above the arresting pin,
 turn it to the required position and lower it back
10
upon the base board.
 Take care that the disk may engage with the
locking pin.
 Retighten the rotary button (3.1).
6.2 Clamping of the drill
 Clamp the spiral drill into the chuck of the drill-
ing machine, and tighten the chuck.
 It is allowed to employ only spiral drills of a
length that does not exceed the indicated maxi-
mum drill length.
6.3 Clamping of the drilling machine
For the drilling machines with a clamping
neck of the dia. of 43 mm, use a reducing
ring.
 Situate the reducing ring in such a way that its
notch may be directed to the clamping point
(8.1).
 Fit the drilling machine into the sleeve and
tighten the clamping screw (8.1).
6.4 Adjustment of the drilling depth
 The upper limit of the stop is set up by means
of the stop ring (7.1) and tightened with the
clamping screw.
 The position of the upper stop can be chosen in
such a way that the drill may be directed by the
guide ring, and the drill tip may be at a distance
of 5 -10 mm from the surface of the base board.
In this way, you avoid a risk of damage to the drill
or the material. The bottom stop ring (7.2) serves
for limiting the drilling depth.
 Find out the required drilling depth by meas-
uring or by a drilling test, and tighten the stop
ring (7.2) under the sleeve.
The stop ring is of importance in particular if you
are to drill several orifi ces of the same depth.
6.5 Additional handle
The additional handle (10) can be mounted in three
positions according to choice (see the sketch). For
the drills the torque of which exceeds 55 Nm, the
extension piece (11) is employed. Always use the
additional handle with the extension piece on the
front side of the sleeve (see the picture).
6.6 Drilling with a parallel guide
Both the parallel guides (2) contribute to the
safety of work. At the same time, they increase
the precision and save time if it is necessary to
drill more orifi ces at the same distance from the
edge of the material. You can choose to use either
one parallel guide at one side, or both the paral-
lel guides at both the sides. The parallel guide is
adjusted either to comply with the mark on the
material (visual control according to the marking
