7.2.2) Insert into the spindle shaft the DPE spacer required to activate the cooling device.

If necessary to use APE... adapter ( see pag.8) the bit must first be fitted in the

corresponding APE adapter and locked with the appropriate grub screw and then

the DPE spacer inserted.

Note: Adapters type APED… do not require use of DPE spacer.

7.2.3) Insert the bit-spacer unit in the spindle shaft so that the two engaging dogs on the

bit spigot line up with the grub screws. Press the bit-spacer unit home against

the inner seat of the spindle: this will enable the DPE spacer to open the

cooling circuit (see Fig. 10).

7.2.4) C

lamp the bit by fully tightening the two grub screws (18) using the 4 mm male

allen key.

FIG. 21 – COOLANT OPERATION WITH SPIRAL BIT

9.3) Drill fitted with special spiral bit

Follow the sequence described in § 9.1, taking care to position the drill on the rail by keeping

the spindle fully withdrawn. Bear in mind that the cooling circuit, instead of being

automatically opened and closed by the guide bit, is kept open at all times by the DPE spacer

fitted on the spigot of the spiral bit; it must therefore be activated, by opening the tap (02),

before starting to drill, then switched off after drilling by closing the tap.
