TRIGGER CONTROLLED VARIABLE SPEED
Your tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from minimum to maximum
nameplate rated RPM by the pressure you
apply to the trigger. Apply more pressure to
increase the speed and release pressure to
decrease speed (Fig. 1).
"LOCK-ON" BUTTON
Your tool is also equipped with a "Lock-ON"
button located on the left side of the trigger
handle that allows for operation at maximum
RPM without holding the trigger (Fig. 1).
TO LOCK TRIGGER "ON": squeeze trigger,
depress button and release trigger.
TO UNLOCK THE TRIGGER: squeeze trigger
and release it without depressing the "Lock-

continuously being depressed,
the trigger can not be released.
PRESET SPEED ADJUSTING DIAL
This feature enables you to preset the trigger
at desired speeds by rotating the dial on the
trigger to a higher or lower setting. Regardless
of the pressure applied on the trigger, the tool
will not operate any faster than maximum
speed setting selected.

OPERATING TIPS

Following a few simple tips will reduce the
wear on both the tool and the operator.
1. Support the tool so that steady even
pressure is applied to the tapping bit. The
pistol grip and contour body has been
designed for comfortable and natural
grasping. The tool can also be supported with
the use of an auxiliary handle (optional
accessory) which can be swielled to a
comfortable position and locked in place.

Operating Instructions
2. The two jaw chuck is suitable for square
shank tapping bits from 1/8" to 3/8" (3 to 9.5
mm). Insert the tapping bit within the jaws of
the chuck and securely tighten screw with the
allen key provided.
3. The gear box is designed for tapping right-
hand threads. Rotation in the right-hand
direction will begin immediately when
pressure is applied to the tap, and the trigger
switch is on. The feature of the chuck is that
the coulpling is self-aligning. This means the
tap will straighten itself along the axis of the
pilot hole if started slightly out-of-align.
4. Once the tap has reached the required
thread depth, the rotation can be reversed by
drawing back the tool which will automatically
reverse the direction of the tap.
5. Thread cutting oil must be used on every
hole when tapping.
6. Using the proper size pilot hole is as
important in tapping as any other factor. Do
not exceed the capacities recommended in
thsi manual for the tool. Use only taps that are
sharp and in good condition.
7. Select a speed suitable for the material
being tapped. Slow speeds are recommended
for large diameter taps. Highter speeds for
small diameter taps.
8. Common causes for broken taps are:
a) Starting tap out-of-align with hole axis.
b) Predrilled hole diameter too small.
c) Blunt or dull taps.
d) Inadequate lubrication
e) Misuse of the tool.
