USER MANUAL GD 320 FESTOOL

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 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 marking11 (1.1) on the base board or with the scale on the parallel guide. The parallel guide is then tightened in the re- quired position by means of the clamping screw (2.1). With the tilting version, the ruler can be ad- justed in the vertical direction (2.2) as well.

6.7 Adjustment of the angle of inclination

(GD 460 A) The tilting drilling stands (GD 460 A) allow for oblique drilling at the angles ranging from 90° to 45°. In perpendicular drilling, the indicator (18) on the scale (17) reads zero. Before the eventual adjustment of the angle of inclination, both the clamping nuts (16) are to be loosened. Now it is possible to tilt the guide bars to the required angle. This angle can be ascertained on the scale (17) with an accurate division. The indicator (18) is set to the required value of the scale, and then both the clamping nuts (16) are tightened again. CAUTION: With the tilted drilling stand, the base board must be secured against sliding along the workpiece, because of safety reasons. The employment of the clamping elements (accessory) is an ide- al way of fastening it.

6.8 Correction of the stop position (GD 460

With the tilting drilling stands, the perpendicular position has been adjusted in the manufacturing plant by means of the stop screw (14). If an additional adjustment of the set stop position is required, proceed in the following way: Loosen the securing nut (14.1) and the clamp- ing nut (16). Bring the foot (15) to rest upon the head of the screw (14). Turning the stop screw in the required direc- tion, you will change the angle to the required position. Tighten the securing nut (14.1) and the clamp- ing nuts (16) again. The indicator (18) can also be reset after haying loosened the screw (19), and screwing it tightly again in the required position.

6.9 Clamping of the drilling stand

For the clamping of the stand upon the material, there serve the clamping elements (12). These can be fastened upon the base board (1). Insert the clamping element into the orifi ce (1.4) from below, screw the clamping nut (12.1) upon it from above, and tighten it. By means of the screw (12.2), tighten it in the required position. The clamping elements (not included in the scope of the delivery but accessories) are used always in pairs, from both the sides. We recommend em- ploying four clamping elements. For materials up to the maximum dimension of 300 mm, the clamping elements can be fastened on the bracket (13). Fit the screws (13.1) from below into the ori- fi ces in the base (1.4). Set the brackets upon the screws (13.1) from above, and tighten them with nuts (13.2). The brackets (which are not included in the scope of the delivery, accessories) are offered in pairs (2pcs). It is necessary to pay attention to the stand to be clamped on the beam between two clamps (12), situated on one bracket (the distribution of forces in the longitudinal sense of the bracket), not by means of two brackets (see the fi gure). The brackets have been designed in such a way that it might be possible to clamp them upon both the basic types of the stands (the vertical ones and the tilting ones) both in the longitudinal and the vertical directions. 7 Drilling - Before you proceed to drilling, make sure that both the spiral drill and the drilling machine are well clamped. - Check the stops and the guide disk, to see, whether they are set tightly, and if necessary, tighten the clamping elements. - Do not work with blunt of damaged drills. - During the drilling operation, hold the equip- ment always with both hands: one hand on the additional handle of the drilling stand, and the other hand on the handle and the switch of the drilling machine. - The marking on the base board (1.2 and 1.3) serves for drilling with visual control according to the mark.

For the spiral drills with even diameters, there is employed a guide disk which is included in the scope of the delivery. For the spiral drills with odd diameters, there is employed a guide disk with odd diameters, supplied as an accessory. For the replacement of the guide disk, unscrew the rotary button (3.1). Next, it is possible to remove the installed guide12 disk and to install another one.

7.2 Drilling jobs without a guiding disk

For working with drills of a larger diameter than 27 mm (up to 45 mm as the maximum), the guide disk can be dismounted in compliance with the above procedure. According to necessity, it is pos- sible to dismount also the springs (5), the stop tube (6) and the depth stops (7.1 and 7.2). In such a case, proceed with utmost care. In any case, we recommend employing the bottom stop ring (7.2) for protection against undesirable contact of the rotating parts with the material. In particular, take care that the rotating parts of the drilling machine or the employed drills may not come into contact with the parts of the drill- ing stand. 8 Maintenance and care Customer service and repair only through manufacturer or service workshops: Please fi nd the nearest address at: www.festool.com/Service EKAT
