at full speed when continuous operation for extended
periods of time is required (fig. d).
To lock the trigger switch in the ON position, pull back on
the trigger switch to start the drill. Continue to squeeze the
trigger until the drill reaches its maximum speed. Push the
trigger switch lock button (5) into the drill handle. Release
the trigger switch while holding the trigger switch lock
button into the drill handle. The drill will continue to run at
full speed. To release the trigger switch lock button, pull
the trigger switch back and then release the trigger.
drilling
When drilling into smooth, hard surfaces such as metal, use a center
punch to mark the desired hole location. This will prevent the drill bit
from slipping off center as the hole is started.
The workpiece to be drilled should be secured in a vice or with
clamps to keep it from turning as the drill bit rotates (fig. e).
1. Check the drill bit to make sure it is firmly locked into the drill chuck,
and verify that the forward/reverse switch is in the forward position.
2. Hold the drill firmly with both hands whenever possible. Use
one hand to grasp the handle and switch.
note: Make sure the hand placed on the body of the drill does
not cover the air vents. Covering these air vents will reduce
motor cooling, and possibly lead to overheating the motor.
3. While holding the drill firmly, place the point of the drill bit at the
point to be drilled. Squeeze the switch trigger to start the drill.
4. M ove the drill bit into the workpiece applying only enough pressure to keep the bit
cutting. Do not force the drill bit or apply sideways pressure to elongate the hole.
warning:
Drill may stall (if overloaded or improperly used) causing a twist. Always
expect the stall. Grip the drill firmly to control the twisting action and prevent loss of control
which could cause personal injury. If a stall does occur, release the trigger immediately and
determine the reason for the stall before re-starting.
When drilling metals, use light oil on the drill bit to keep it from overheating. The oil
will prolong the life of the drill bit and improve the cutting action. If the bit jams in the
workpiece, or if the drill stalls, release the trigger switch immediately. Remove the bit
from the workpiece and determine the reason for jamming.
• 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.
• 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.
• 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.
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.
