downward feed pressure and the spindle will
stop.

When the machine is pulled back, the spindle
will automatically spin in the left hand
(counterclockwise) direction at high speed (in
order to more quickly remove the tap).
CAUTION: Do not pull too hard when backing
out or the tap could pull out of the chuck. This
could lead to premature wear of the chuck.
THE DEPTH STOP
The depth stop is useful when tapping blind holes
to avoid bottoming out the tap. It may be moved
back out of the way (or removed entirely) when not
needed.
To set the depth stop:
1.
Loosen the locking screw and adjust the bar
so that it is flush with the end of the tap. This
will be the zero position.
2.
Take the intended tapping depth and subtract
4mm. Then back off the bar by this amount.
(4mm must be subracted because of the
internal mechanism)
3.
Once the desired position is set, retighten the
lock screw.
Example:
If the desired tapping depth is 14mm,
then the depth stop bar should be set to 10mm
back from the end of the tap. (14mm minus 4mm =
10mm)
NOTE: It is not possible to tap left-hand threads
with this machine
WARNING: Always hold tightly to both handles
to resist the torque forces created during the
tapping operation.
WARNING: Never attempt to tap without using
the side handle and always ensure that the
handle is tight before operating.
