1.To lock the trigger, hold the lock button in while pulling the trigger. Release the trigger.
2.To unlock the trigger, pull the trigger and release. The lock button will pop out.
WARNING!
To reduce the risk of explosion, electric shock and property damage, always check the work area for hidden pipes and wires before drilling.
Drilling
1. | Before drilling, be sure the workpiece |
| is clamped securely. Use backing ma- |
| terial to prevent damage to the work- |
| piece during breakthrough. |
2. | When starting a hole, place the drill bit |

a full stop before reversing. |
WARNING!
To reduce the risk of injury, keep hands and cord away from the bit and all moving parts.
Starting, Stopping and Controlling Speed
1.To start the tool, pull the trigger.
2.To stop the tool, release the trigger.
3.To vary the drilling speed, simply in- crease or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
Locking Trigger (Fig. 11)
The lock button holds the trigger in the ON position for continuous full speed use.

on the work surface and apply firm |
pressure. Begin drilling at a slow speed, |
gradually increasing the speed as you |
drill. |
3. Always apply pressure in line with the |
bit. Use enough pressure to keep the |
drill biting, but do not push hard enough |
to stall the motor. |
4. Reduce pressure and ease the bit |
through the last part of the hole. While |
the tool is still running, pull the bit out of |
the hole to prevent jamming. |
Stalling
If the tool seems as if it is about to stall, maintain a firm grip and reduce pressure slightly to allow the bit to regain speed. If the tool does stall, release the trigger im- mediately. Reverse the motor, remove the bit from the work and start again. Do not pull the trigger on and off in an attempt to start a stalled drill. This can damage the drill.
NR = Not recommended
Selecting Bits
When selecting a bit, use the right type for your job. For best performance, always use sharp bits.
Drilling in Wood, Composition Materi- als and Plastic
When drilling in wood, composition materi- als and plastic, start the drill slowly, gradu- ally increasing speed as you drill. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit flutes. Use low speeds for plastics with a low melting point.
Drilling in Masonry
When drilling in masonry, use high speed
Drilling in Metal
When drilling in metal, use high speed steel twist drills or hole saws. Use slow speeds for hard metals and high speeds for softer metals. Lubricate drill bits with cutting oil when drilling in iron or steel. Use a coolant when drilling in nonferrous metals such as copper, brass or aluminum. Back the mate- rial to prevent binding and distortion on breakthrough.
Driving Screws
When driving screws, use the proper screwdriver bit for your job. After drilling pilot and shank holes, start the screw slowly and increase the speed as driving progresses. Set the screw by slowing to a stop. Do not run screws down at exces- sive speeds. To remove screws, reverse the motor.
WARNING!
High rotational force. To reduce the risk of injury, always hold or brace secrely. Always use side handle on tools rated 1200 RPM or less.
