8.1.5) ONLY FOR LD-4EF DRILL

Set the motor speed, by means of the selec-

tor switch under the automatic switch (see

Fig. 17e), in correlation to the diameter of the

hole to be. We suggest to use the standard

speed (280 rpm) for holes smaller than ø 28

mm and the lower speed (250 rpm) for holes

between dia 28 and 40 mm inclusive.

8.1.6) Proceed to drill by initially applying light pressure on the lever (36), increasing

the pressure progressively, avoiding jolts, and ﬁ nally relieving the pressure

in the exit phase. When drilling close to raised markings on the rail the initial

pressure must be extremely light until the markings disappear, otherwise the

cutter may be damaged.

8.1.7) The guide bit will enable the lubrocoolant to be discharged throughout the drilling

process.

8.1.8) When drilling has been completed, fully retract the spindle, stop the motor by

pressing the automatic switch (position " 0 "), and make sure that drilling swarf

is removed before recommencing drilling.

8.1.9) After drilling it is advisable to remove all swarf from the tool and spindle area.

8.2) Drill ﬁ tted with “long” type broach cutter

(for drilling thicknesses of up to 50 mm).

Follow the sequence described in § 8.1, taking

care to position the drill on the rail by keeping

the spindle fully withdrawn.
