not only the flat on the tap, but also the round shank. r
on the chuck and insert the tap—all the way in—close top ring until it
grips on the flats. With the chuck key, tighten the chuck jaws—TIGHT.
How to Remove Chuck
Block the chuck out fivn the tapper frame in the farthest or reverse
position and insert a small rod through the open jp^ against the taper
nose of the attachment. Strike a sharp blow with a hami-ur and the chuck
will come loose. Don’t try to wedge the chuck off as it wiil pull the clutch
apart.

How to Operate
It requires very little pressure to drive the tap into the hole; do not force it. When the required
depth is reached, the depth stop nut will strike the frame and cause the attachment clutch to release.
Allowing the foot lever to return to top position, engages the return clutch and backs the tap out. Do
not let the lever return without some foot pressure as the attachment will strike the head frame and
damage the attachment.
The proper speed at which to run the spindle is dependent on the size tap, size of drilled hole,
sharpness of tap and kind of material. Don’t let tne attachment run hot.
