N.B.: make sure the mains voltage corresponds to that on the drill rating plate.
N.B.: switch on the cooling system before starting the drill (§ 4).
8.1) Drill fitted with “short” type broach cutter
(for drilling thicknesses of up to
25 mm
).
The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1), clamping
end piece (§ 7.1), positioning template (§ 7.3), the drill being clamped to the rail (§ 7.4), as follows:
8.1.1)
Connect the female quick-coupling of the
SR5000 coolant unit to the male coupling
(12)
on the drill.
8.1.2)
Open the tap (02) fitted onn the coolant unit hose.
8.1.3)
Using the lever (36) bring the guide bit almost in contact with the rail (Fig. 17a); keeping
the release pawl (39) pressed, release the lever from its cup and return it to the initial position
(Fig. 17b), which will enable the travel of the lever (36) to be used in the most advantageous way.
8.1.4)

CAUTION: the automatic switch is equipped with
protection against motor overheating and with an under-
power relay; should the motor overheat or there is a fall
in voltage below the relay cut-out setting, the switch will
move into the "0" position. At this stage, if the conditions
are correct, the switch will have to be re-set manually.
