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 drill, complete with the clamping termination (§ 7.1) and the positioning shoe (§
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 drill 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 positioning relative to the
longitudinal axis of the rail is required, use the reference rod (18).
