WaRning:
Make certain the lock-off
button is engaged to prevent switch
actuation before installing or removing
accessories.
To insert a drill bit or other accessory:
1. Grasp the rear half of the chuck (3)
with one hand and use your other
hand to rotate the front half (3a) 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
holding the rear half of the chuck and
rotating the front portion in the clockwise direction as viewed from the chuck end.
WaRning:
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.
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.
• 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.
• 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.
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.
MaintenanCe
Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
iMpoRtant:
To assure product SAFETY and RELIABILITY, repairs, maintenance and
adjustment (other than those listed in this manual) should be performed by authorized
service centers or other qualified service personnel, always using identical replacement parts.
