Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Y
our tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from the minimum to the maximum
nameplate RPM by the pressure you apply to
the trigger. Apply more pressure to increase
the speed and release pressure to decrease
speed. This accurate speed control enables
you to drill without center punching. It also
permits you to use as a power screwdriver.
Bits are available for driving screws as well as
running bolts and nuts.
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 and accidental
battery discharge. For forward rotation, (with
chuck pointed away from you) move the 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.
ADJUSTABLE CLUTCH
Your tool features 6 clutch settings. Output
torque will increase as the clutch ring, is
rotated from 1 to 5. The drill “ ” position
will lock up the clutch to permit drilling and
driving heavyduty work, and also enables bits
to be changed quickly and easily in the
keyless chuck.
BRAKE
When the trigger switch is released it
activates the brake to stop the chuck quickly.
This is especially useful in the repetitive
driving and removal of screws.
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
b
etween the chuck jaws and the bit shank.
To tighten, hold the chuck collar firmly with
one hand and securely tighten the chuck
sleeve with the other hand (Fig. 2).
Do not use the power of
the drill while grasping
chuck to loosen or tighten bit.
Friction burn
or hand injury is possible if attempting to
grasp the spinning chuck.
REMOVING CHUCK
Rotate the clutch ring to the drill bit
symbol “ ”. Open the chuck all the way,
remove left-hand thread screw inside chuck
by turning it clockwise. Insert the short arm of
a 3/8" hex key wrench and close jaws on flats
of wrench. Strike long arm of wrench sharply
counterclockwise, remove wrench and
unthread chuck from spindle (Fig. 2).
INSTALLING CHUCK
Always keep the spindle threads, the threads
of the chuck and securing screw free of
debris. To install a chuck, reverse “removing
the chuck” procedure.
