The spindle is advanced by moving the

lever (36) (See Fig. 6 a). The lever is ﬁ t-

ted with a release pawl (39) which, when

pressed, renders it independent of the

hub and hence the spindle; the opera-

tor can therefore easily vary the angular

position of the lever without movement of

the spindle (Fig.6).

6c - With the hub released, moving the lever

towards the operator produces a cor-

responding advance of this spindle.

6a - Moving the lever (36) towards the

operator produces a corresponding

advance of the spindle.

5.1) Adjustment of the advance lever

The movement of the lever must never be

loose, for adjustment proceed to tighten it by

loading the cup springs by means of the as-

sociated self-locking nut, after removing the

protective cap (see Fig. 7).

6b - With the release pawl (39) pressed, the le

ver is released from its hub and can repeat

the previous travel without the spindle moving.

When work has been completed, put away the drill by proceeding as follows:

12.1) Depressurise the tank of the SR5000 cooling unit (see § 4), close the tap (02) on

the tube from the tank, and disconnect the quick-coupling (03).

12.2) Carefully clean the drill, particularly in the spindle area, removing machining waste

(swarf, etc.) and any deposits of lubricating coolant.

12.3) Fully withdraw the spindle.

12.4) Place the drill and the SR5000 cooling unit in a sealed place free from dust, mois-

ture and the risk of accidental impact.

For better protection

Cembre

recommends the use of the VAL LD metal case designed

for this purpose (see § 3.2). The DBG-F2 moving arm device allows the drill to be

housed and locked in the case. A suitable housing is also provided in this VAL LD for the

VAL MPA case containing the most commonly used accessories.
