Keyless Chuck = Figure G A
WARNING:
Make certain the battery
pack is removed to prevent tool actuation
before installing or removing accessories.
To insert a drill bit or other accessory:
1. Grasp the chuck (5) and rotate it in the
counterclockwise direction, as viewed
from the chuck end.
2. Insert the bit or other accessory fully
into the chuck, and tighten securely
by rotating the chuck in the clockwise
direction as viewed from the chuck end.
WARNING:
Do not attempt to tighten
or loosen drill bits (or any other accessory)
by gripping the front part of the chuck and
turning the toot on. Damage to the chuck
and personal injury may occur when
changing accessories.
Screw Driving
• For driving fasteners, the forward/reverse button should be pushed to the left.
• Use reverse (button pushed to the right) for removing fasteners.
NOTE: When moving from forward to reverse, or vice versa, always release the trigger
switch first.
Drilling
• Use sharp drill bits only.
• Support and secure work properly, as instructed in the Safety Instructions.
• Use appropriate and required safety equipment, as instructed in the Safety Instructions.
• Secure and maintain work area, as instructed in the Safety Instructions.
• Run the drill very slowly, using light pressure, until the hole is started enough to keep the
drill bit from slipping out of it.
• Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting
but not so much as to stall the motor or deflect the bit.
• Hold the drill firmly with two hands, one hand on the handle, and the other gripping
the bottom around the battery area or the auxiliary handle if provided.
• DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT
TO START IT. DAMAGE TO THE DRILL CAN RESULT.
• Minimize stalling on breakthrough by reducing pressure and slowly drilling through the
last part of the hole.
• Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming.
• Make sure switch turns drill on and off.
Drilling in Wood
Holes in wood can be made with the same twist drill bits used for metal or with spade
bits. These bits should be sharp and should be pulled out frequently when drilling to
clear chips from the flutes.
Drilling in Metal
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass
which should be drilled dry. The cutting lubricants that work best are sutfurized cutting oil
or lard oil.
Drilling in Masonry
Use carbide tipped masonry bits. Refer to Drilling section. Keep even force on the drill but
not so much that you crack the brittle material. A smooth, even flow of dust indicates the
proper drilling rate.
LED Work Light
When drill is activated by pulling the trigger switch (1), the integrated LED work light (8)
wilt automatically illuminate the work area. NOTE: The work light is for lighting the
immediate work surface and is not intended to be used as a flashlight.
Bit Tip Storage
A bit storage slot (9) is built into the base of the tool.
