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:

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.
