5.4.3 Setting the travel limter stop
When at its lowest position, the travel limiter stop will not effect the stroke of
the slide. When tapping blind holes the travel limiter s top mus t be used to
avoid the tap bottoming. When tapping through holes or when drilling, the
limiter stop is not needed.
To properly set:
•
With the tap mounted on the machine, place the machine on the
workpiece.
•
Using the depth meter (1), carefully measure the furthest depth
that the tap i s intended to go. With the tap over hanging the edge
o f the workpiece, lower the slide to the intended depth.
•
Loosen the lock nut (2) then adjust the stop to just meet the slide,
retighten the lock nut.
•
When no longer needed, lower the stop to its lowest position
.
5.4.5
Tapping operation
NOTE: It is recommended to always use cutting oil on the tap
to give longer tap life and better results. The automatic cool-
ant system only works for annular cutters. Taps must be lu-
bricated manually.
•
Before tapping begins, there must be a proper sized hole. Make
sure that the hole is the correct size for the tap.
•
With the magnet switch s till off , manoeuvre the tap and ma-
chine to ensure that the tap is perfectly aligned with the hole. Ac-
tually insert the nose of the tap into the hole slightly to ensure
perfect alignment, then switch on the magnet.
•
If you are tapping a blind hole, please use the Travel Limiter Stop
and the tapping depth meter see “THE PROPER USE OF THE
TAPPING DEPTH METER” and "SETTING THE TRAVEL
LIMITER STOP" above.
•
To begin tapping, start the machine by turning on the motor
switch and use the crank to feed the tap to the work. When there
is no feed pressure from the crank, the spindle will be in neutral
and will not spin. When there is forward feed pressure , the spin-
dle will automatically spin in the forward (right hand) direction.
Tap the hole, then simply back out the crank to reverse the spin-
dle and remove the tap. When there is backward pressure from
the crank, the spindle will automatically spin in the reverse (left
hand) direction. (Note that it is not possible to tap left hand
threads with this machine).
5.4.6 Settin gup for twist drilling
CAUTION: Never use a cutting tool which is larger than the
maximum rated capacity of the machine.
NOTE: It is recommended to always use cutting oil on the
twist drill to give longer drill life and better results. The au-
tomatic coolant system only works for annular cutters. Twist
drills must be lubricated manually
•
If it is not mounted, mount the chuck to the Drill Chuck Arbor.
•
Push up on the Quick-Release Collar to mount the Drill Chuck
Arbor to the machine. Double check to ensure that the arbor is
locked in place.
•
Insert the drill bit into the chuck and tighten with the chuck key.
•
If it is in tapping mode, shift the gearbox to drilling mode by
swinging the gear selector tab out of the detent slot then shifting
upwards into drilling mode. Then pop the selector tab back into
the detent. It will usually be necessary to grab the arbor and
push the spindle upwards while turning a little by hand to get the
selector to shift all the way up. Only grab the Arbor when turning
the spindle, never the Quick-Release Collar. Otherwise, it will be
easy to accidentally release the arbor and it will fall out. Follow
the Twist drill & annular cutter” symbol on the gear case. (The
small arrow on the tab will be pointing downwards when it is
shifted correctly).

Proceed to drill as described below titled: "OPERATION-
