NOTE: To engage the hammering mechanism, maintain pressure on the bit. When pressure on the bit is released, the hammering action will stop.
Using Forward/Reverse Lever (Fig. 6)
The forward/reverse lever can only be adjusted when the trigger is not pressed. Always allow the motor to come to a complete stop before using the forward/reverse lever.
Fig. 6 Forward
Reverse
1.For forward (clockwise) rotation, push the forward/reverse lever to the left (when viewed from the back of the tool) as shown.
2.For reverse (counterclockwise) rotation, push the forward/reverse lever to the right (when viewed from the back of the tool) as shown. Allow the motor to come to a full stop before reversing.
NOTE: When
Selecting Speed (Cat. No. 5387-20 only)
The speed can only be changed when the tool is at a complete stop.
1.For high torque/low speed (up to 1000 rpm), turn the speed selector to position 1.
2.For low torque/high speed (up to 2500 rpm), turn the speed selector to position 2.
Starting, Stopping & Controlling Speed
1.To start the tool, pull trigger.
2.To stop the tool, release trigger.
3.To vary the speed, increase or decrease pressure to trigger. The further the trigger is pulled, the greater the speed.
Operating
Position the tool, grasp the handles firmly and pull the trigger. Always hold or brace the tool securely using both handles and maintain control. This tool has been designed to achieve top performance with only mod- erate pressure. Let the tool do the work.
If the speed begins to drop off when drilling deep holes, pull the bit partially out of the hole while the tool is running to help clear dust. Do not use water to settle the dust since it will clog the bit flutes and tend to make the bit bind in the hole.

APPLICATIONS
WARNING!
To reduce the risk of electric shock, check work area for hidden pipes and wires before drilling.
Drilling in Wood, Composition Materials and Plastic
When drilling in wood, composition materials and plastic, select the drill operating mode. Start the drill slowly, gradually increasing speed as you drill. Select low speeds for plastics with a low melting point.
Drilling in Metal
When drilling in metal, select the drill operating mode. Use high speed steel twist drills or hole saws. Use a center punch to start the hole. 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 material to prevent binding and distortion on break- through.
Drilling in Masonry
When drilling in masonry, select the
