SAFETY INSTRUCTIONS

(For All Tools)

WARNING: WHEN USING ELECTRIC TOOLS, BASIC SAFE-

TY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO

REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND PER-

SONAL INJURY, INCLUDING THE FOLLOWING:

READ ALL INSTRUCTIONS.

1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.

2.CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp or wet locations. Keep work area well lit. Don't expose power tools t o rain. Don't use tool in presence of flammable liquids or gases.

3.KEEP CHILDREN AWAY. All visitors should be kept away from work area. Don't let visitors contact tool or extension cord.

4.STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked-up place - out of reach of children.

5.DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.

6.USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavy-duty tool. Don't use tool for purpose not intended.

7 . DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair.

8.USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty.

9.DON'T ABUSE CORD. Never carry tool by cord or yank it t o disconnect from receptacle. Keep cord from heat, oil, and sharp edges.

IO. SECURE WORK. Use clamps or a vise t o hold work. It's safer than using your hand and it frees both hands to operate tool.

11. DON'T OVERREACH. Keep proper footing and balance at all times.

12.MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing acces- sories. Inspect tool cords periodically and if damaged, have repaired by autho- rized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.

13.DISCONNECT TOOLS. When not in use, before servicing, and when chang- ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking t o see that keys and adjusting wrenches are removed from tool before turning

it on.

15.AVOID UNINTENTIONALSTARTING. Don't carry plugged-in tool with finger on switch. Be sure switch is OFF when plugging in.

16.OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords intended for use outdoors and so marked.

17.STAY ALERT. Watch what you are doing, use common sense. Don't operate tool when you are tired.

18.CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized serv- ice center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Don't use tool if switch does not turn it on and off.

19.GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.

20.REPLACEMENTPARTS. When servicing, use only identical replacement parts.

21.POLARIZED PLUGS: To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. Ifit still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

VOLTAGE WARNING: Before connecting the tool t o a power source (receptacle, outlet, etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor.

ADDITIONAL SAFETY RULES

1.Always be sure you have a firm footing.

Be sure no one is below when using the tool in high locations.

2.Hold the tool firmly.

3.Keep hands away from rotating parts.

4.When drilling into walls, floors or wherever "live" electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL!

Hold the tool by the insulated grasping surfaces to prevent electric shock if you drill into a "live" wire.

5.Do not leave the tool running. Operate the tool only when hand-held.

6.Do not touch the drill bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin.

SAVE THESE INSTRUCTIONS.

Installingside grip (auxiliary handle)

Screw the side grip on the tool securely.

Installing or removing drill bit

CAUTION :

Always be sure that the tool i s switched off and unplugged before installing or removing the bit.

To install the bit, place it in the chuck as

far as it will go. Tighten the chuck by hand.Chuck kev Place the chuck key in each of the three

holes and tighten clockwise. Be sure to tighten all three chuck holes evenly.

To remove the bit turn the chuck key counterclockwise in just one hole, then loosen the chuck by hand.

Switch action

Tool speed i s increased by increasing pres- sure on the trigger. To start the tool, simply pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool from the locked position, pull the trigger fully, then release it.

CAUTION :

Before plugging in the tool, always check to see that the trigger switch actuates porperly and returns to the "OFF" position when released.

Reversingswitch action

This tool has a reversing switch to change the direction of rotation. Move the revers- ing switch lever to the "FWD" position for clockwise rotation or the "REV" position for counterclockwise.

CAUTION:

0 Always check the direction of rotation before drilling.

0 Use the reversing switch only when the tool comes to a complete stop. Changing the direction of rotation before the tool stop may ruin the tool.

Drilling operation

Drilling in wood

When drilling in wood, best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

0Drilling in metal

To prevent the bit from slipping when starting a hole, make an indentation with a center- punch and hammer a t the point to be drilled. Place the point of the bit in the indenta- tion and start drilling.

Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.

CAUTION :

*Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool.

*There is a tremendous force exerted on the tool/bit a t the time of hole break through. Hold the tool firmly and exert care when the bit begins to break through the workpiece.

*Always grip the small workpiece firmly with a vise or a holding means.

*A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool will pull away easily unless you hold it firmly before starting the tool.
