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
The "Lock-ON" button, located in the handle
of your tool allows for continuous operation at
maximum RPM without holding the trigger.
TO LOCK TRIGGER "ON": squeeze trigger,
depress button and release trigger.
TO UNLOCK THE TRIGGER: squeeze trigger
and release it without depressing the "Lock-
ON" button.
If the “Lock-ON” button is
continuously being depressed,
the trigger can not be released.
REVERSING SWITCH LEVER
The reversing switch lever is located above the
trigger switch and is used to reverse rotation of
the bit. The reversing switch should only be
activated when the motor is “OFF” and when
bit is at a complete standstill (Fig. 1).
To use tool in “Forward” rotation move lever to
left side of tool, to “Reverse” the rotation of the
bit move the lever to the right side of the tool.
Do not change direction of
rotation until the tool comes
to a complete stop. Shifting during rotation of
the chuck can cause damage to the tool.

WARNING
MODE SELECTOR SWITCH
The mode selector switch allows the tool to
be set for various drilling applications. Slide
the switch right or left depending on the
below applications (Fig. 1).
Drill only action: For drilling in
woods, metals, plastics or other non
concrete materials.
Drill with hammer action: For drilling
in concrete, asphalt, tile or other
similar hard materials.
GEAR CHANGE SELECTION
Gear selection: The proper gear selection is
directly related to the speed and torque
required for various jobs. The following should
be adhered to when selecting the proper gear:
Speed 1 = low speed with high torque
Speed 2 = high speed with low torque
Changing gears: Change gear position only
with the motor at a complete standstill. To
change gears rotate the gear selection lever.
If you have difficulties changing from one gear
to the other, turn the chuck by hand until the
gears engage (Fig. 1).
AUXILIARY HANDLE
The auxiliary handle will provide additional
control, support and guidance for the drill.
The handle is adjustable to any position
around the 360˚ handle collar mount.
Installing side handle: Slide the handle over
the handle collar mount. Securely tighten wing
knob (A).
DEPTH GAUGE
Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle is
installed, slide the depth gauge to desired
depth and securely tighten wing knob (B).
INSERTING BIT
For small bits, open jaws enough to insert the
bit up to the flutes. For large bits, insert the bit
as far as it will go. Center the bit as you close
the jaws by hand. This positions the bit
properly, giving maximum contact between the
chuck jaws and the bit shank.
To tighten chuck, insert key into each of the
three key holes in succession and tighten
clockwise firmly. The chuck can be released by
using one hole only (Fig. 2).
