3. TABLE SUPPORT INCLINATION ADJUSTMENT
Loosen the three nuts nr.8 (page 9) and adjust the table inclination, as per the necessary degrees, which are shown in
the arm ruler.
Once finished the adjustment, loosen again the three nuts.
4. TABLE TURNING ADJUSTMENT
Unlock the locking command nr.9 (page 9) of the support and adjust the table rotation. Lock again the locking command
nr.9 (page 9) of the support.
5. SPEEDS CHANGE
The commands shown with nr.2 (page 9) are the commands to change the speed. The different speeds are shown in the
plates, placed at one side of the above commands.
Advise: Before the speed change, make sure that the spindle is completely stopped.
6. DRILLING DEPTH
To adjust the drilling depth, loosen the locking nuts nr.7 (page 9) and turn the adjusting command of the depth index
nr.23 in one or another direction. The indexing arrow nr.14 (page 9), will show us in mm. or inches, the drilling depth.
Once the regulation is over, re-tighten the locking nuts nr.7 (page 9).
7. AUTOMATIC FEED (MECHANICAL CLUTCH).
It is carried out by means of a light lateral displacement of any of the four commands nr.2, as per drawing nr.3 (page 4)
clutching the power feed automatically, displacing the lever nr.1 to the "C" position, as per drawing nr.3 (page 4). To
obtain the different feeds, we will use the feed selector nr.3 (page 9). The different feeds are shown in the plate. There
are two ways of disconnecting the power feed of the main spindle:
• Manual release: By means of the lever nr.1. Place it in "D" position as per drawing nr.3 (page 4).
• Automatic release: By regulating the drilling depth indicator arrow (see point 6).
8. AUTOMATIC FEED (ELECTROMAGNETIC CLUTCH).
The automatic feed by electromagnetic clutch is released by pressing the push-button at the end of any of the four lever
nr.4 (page 9) engaging the working feed automatically. To obtain the different feeds we will use the feed selector nr.3
(page 9), as per indicated on the plates. There are three ways to release the automatic feed of the main spindle:
• Manual release:
Pressing the push-button at the end of any of the four-lever nr.2, as per drawing nr.3 (page 4).
Pressing the "RELEASE" "STOP", in the push-button plate nr.13 (page 9).
• Automatic release: By regulating the drilling depth indicator arrow (see point 6).
9. FINE SENSITIVE MANUAL FEED.
Place the feed selector nr.3 (page 9) in "O" position (dead point). Clutch the power feed by means of a lateral
displacement of any of the four-command nr.2 (page 4). In this way, by manual rotation of wheel nr.18 (page 9), we can
work with the fine sensitive manual feed.
10. PAIR LIMITER
To avoid breaking in the mechanisms (for example in over loading cases), the machine is provided with a pair limiter in
the feed box. If for any reason we need to adjust the pair limiter, we have the nut nr.40-1/43 (page 11D).
11. AUTOMATIC TOOL EJECTOR
Pull from command nr.3 and place in "B" position, as per drawing nr.2 (page 4), adjust the tool with your left hand and
with your right hand give a dead blow in clockwise sense with command nr.2 (page 4) in the upper part of the main
spindle stroke. As per drawing nr.3 (page 4).
Advise: It is important that the command nr.3 (page 4) is always in "A" position for working operations (See drawing
nr.2).
12. SHANK LOCKING
Loosen with an Allen key the screw nr.20 (page 9).
Advise: We recommend you to use it only for milling operations.

MORE COMMON FAILURES
BREAKAGE OF THE RETURN SPRING.
Remove the protection cover and withdraw the spring for its replacement, place the central end of the spring in the shaft slot,
holding the other end with a Grip vice. Rotate the Grip vice in the anticlockwise direction until the suitable tension is obtained.
After this, introduce the screw in the spring holding housing, as per drawing nr.1 (page 4).
