Ensure that the cutter is retracted sufficiently to avoid touching the rail prior to
clamping the drill to the track.
The clamping handle can be lifted out of the clamping
arms as shown here. Manoeuvre the drill up and over the
rail.
Lower into position on the index plate taking care to align
it over the positioning block. Ensure that the rail shoe
template sits fully into the rail web.
Position the threaded boss on the clamping handle back
into the clamp arms. And begin to tighten the clamping
handle.
Continue to tighten the clamping handle until the rollers
contact the rail head. Finally, raise and lower the drill body
slightly whilst tightening the clamp.
Fit the cutter feed handle square drive into the drill
(this can be fitted for either left or right hand operation)
