7.4) Clamping to the rail web (Ref.to Fig. 16)
The special shape of the positioning shoes, each corresponding to the type of rail, enables
the drill to be positioned quickly, accurately and safely on the element to be drilled.
To position the drilling machine, complete with the clamping termination (§ 7.1) and the
positioning template (§ 7.3) suitable for the type of rail to be drilled, proceed as follows:
7.4.1) Withdraw the spindle shaft (07) completely by means of the lever (36).
7.4.2) Bring the moving arm (03) of the clamping device into the fully open position by
means of the handwheel (11).
7.4.3) Place the machine on the rail at the point where the drilling is to be carried out, and
clamp it by tightening the handwheel (11) right down: the positioning shoe will
automatically position the cutter or spiral bit in line with the desired axis; if accurate po-
sitioning relative to the longitudinal axis of the rail is required, use the reference pin (18).
