adjusting, adding accessories, or checking a function on the tool.
TRIGGER SWITCH ACTION

switched off.
Your tool is equipped with a variable speed trigger switch. The tool speed is controlled by the amount of pressure
you apply to the switch trigger.
• Turn the drill on by depressing the trigger switch.
• Depressing the switch further will produce more speed and torque.
• Use the reversing switch (2-FIG 1) to change the direction of rotation of the drill. Always check the rotation
before beginning your work.

continuously operate the drill at a preset RPM without holding down the switch trigger.
To lock the trigger “ON”, pull the switch trigger back fully, depress the “Lock-On” button and release the trigger.
To unlock the trigger, squeeze the trigger back completely then release it without depressing the “Lock-On”
button.

POWER-ON INDICATOR
The drill is equipped with a Power-On Indicator on the top of drill body (5-FIG 1). It lights up when the drill is being
connected to a power source.
CHUCK
WARNING: Always be sure that the tool is switched off and unplugged before
adjusting, adding accessories, or checking a function on the tool.
The drill is equipped with a 3/8" (10mm) metal Keyed Chuck. (1-FIG 1). A chuck key is provided to tighten or loosen
the chuck jaws.
To install a drill bit:
Inspect the drill bit shank and the drill’s chuck jaws for dirt or foreign matter and clean if necessary. Dirt on the drill
bit shank or on the chuck jaws can cause misalignment or bit slippage during use. Drill bits larger than the drill’s
maximum rated capacity may cause the motor to overload and/or gear damage.
• Unplug the drill.
• Open the chuck jaws so the opening is slightly wider than the drill bit being installed.
• Position the drill so the chuck is pointing upward then insert the drill bit, allowing the bit to rest on the bottom
of the chuck. For small bits, insert the drill bit so that the bottoms of its flutes are even with the top of the
chuck jaws.
• Center the bit in the jaws and hand tighten the jaws by rotating the chuck collar clockwise, being sure the bit is
properly aligned in the chuck jaws.
• Insert the chuck key into one of three holes in the chuck, turning the chuck key clockwise to
securely tighten
the chuck. DO NOT use a wrench, pliers, or means other than the chuck key to tighten or loosen the chuck.
WARNING: Never attempt to operate a bit that is wobbly, unstable, or broken.
WARNING: To prevent personal injury, always remove the chuck key from the
chuck after each use.
