Keyless Chuck - Figure I
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.
Do not attempt to tighten drill
bits (or any other accessory) by gripping the
front part of the chuck and turning the tool
on. Damage to the chuck and personal
injury may occur when changing
accessories.
Screw Driving
For driving fasteners, the reversing button should be pushed to the left. Use reverse
(button pushed to the right) for removing fasteners. When moving from forward to
reverse, or vice versa, always release the trigger switch first.
On Board Bit Storage
A bit storage slot is built-in to the area just above the battery.
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 one hand on the grip and the other hand on the bottom of the
battery pack to control its twisting action.
• 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 sulfurized 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.
