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. lf for any reason we need to adjust the pair limiter, we have the nut nr.40.1/43
(page 11H).
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(PAGE 4)).
12. SHANK LOCKING
Loosen with an Allen key the screw nr.20 (page DESCRIPTION).
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).

• Do not work in automatic feed, while command nr.3 is in "B" position, as per nr.2 and 3 (PAGE 4).
• Take special care, while working in manual or automatic feed, with command nr.4 (page DESCRIPTION)
when it returns, due to the elastic energy of the return spring of the main spindle.
