Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger. The
speed can be adjusted from the minimum to
maximum nameplate 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
(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-
ON" button.
If the “Lock-ON” button is
continuously being depressed,
the trigger can not be released.
FORWARD/REVERSING LEVER &
TRIGGER LOCK
Your tool is equipped with a forward/reversing
lever and trigger lock located above the trigger
(Fig. 1). This lever was designed for changing
rotation of the chuck, and for locking the
trigger in an“OFF” position to help prevent
accidental starts. For forward rotation, (with
the chuck pointed away from you) move lever
to the far left. For reverse rotation move the
lever to the far right. To activate trigger lock
move lever to the center off position.
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
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.
KEYED MODELS
To tighten chuck, insert key into each of the
three key holes in succession and tighten
firmly. The chuck can be released by using
one hole only (Fig. 3).
KEYLESS MODELS
To tighten, hold the chuck collar firmly with
one hand and securely tighten the chuck
sleeve with the other hand (Fig. 4).
To prevent friction burns, or
possible hand injury, do not
loosen or tighten the chuck by using the power
of the drill.
CHUCK KEY OR BIT STORAGE AREA
Keyed models are equipped
with a chuck key
that is conveniently located in the handle base
where it is always handy and unlikely to get lost or
misplaced (Fig. 1).
