KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don't use power tools
in damp
or wet locations. Keep work area well
lit. Don't expose power tools torain.
Don't use tool
in presence of flammable liquids or gases.
KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
STORE IDLETOOLS. When not
in use, tools shouldbestored in dry, and high
or locked-up place - out of reach of children.
DON'T FORCETOOL.
It will dothejob betterand safer atthe ratefor which
it was intended.
USE RIGHT TOOL. Don't force small tool or attachment todo the job of a
heavy-dutytool. Don't use tool for purpose not intended; for example, don't
use circular saw for cutting tree limbs or logs.
DRESS PROPERLY. Don't wear loose clothingorjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering tocontain long hair.
USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
DON'T ABUSE CORD. Never carry tool by cord or yank
it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it frees both hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspect toolcords periodicallyand
if damaged, haverepairedbyautho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not inuse, beforeservicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removed from tool beforeturning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger on switch.
Be sure switch is OFF when plugging
in.
16. EXTENSION CORDS. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord will cause a drop
in line voltage resultingin loss of power and overheating. Table 1 shows the
correct size to use depending oncord lengthand nameplate ampere rating.
If
in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

17. OUTDOOR USE EXTENSIONCORDS. When toolisusedoutdoors, use only
extension cords intended for use outdoors and so marked.
18. STAY ALERT. Watch what you aredoing, use common sense. Don't operate
tool when you are tired.
19. 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 itsintendedfunction. Check for alignment of
moving parts, bindingof moving parts, breakageof parts, mounting, andany
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 indicatedelsewhere inthis instruction manual.
Have defective switches replaced
by authorized service center. Don't use
tool if switch does not turn
it on and off.
20. GUARD AGAINST ELECTRIC SHOCK. Preventbody contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21. REPLACEMENT PARTS. When servicing, useonly identical replacementparts.
22. POLARIZEDPLUGS. 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. If
it still doesnot fit, contact a qualified electrician toinstall
the proper outlet. Do not change the plug in any way.

VOLTAGE WARNING: Before connecting the tooltoa 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. Wear a hard hat (safety helmet), safety glasses and/or face shield. It is also
highly recommended that you wear a dust mask, ear protectors andthickly
padded gloves.
2. Be sure the bit is secured in place before operation.
3. Under normaloperation, the tool isdesignedtoproducevibration. Thescrews
can come loose easily, causing a breakdown or accident. Check tightness
of screws carefully before operation.
4. In cold weather or when the tool has notbeen used for a longtime, let the
tool warm up for several minutes by operating it under no load. This will
loosen up the lubrication. Without proper warm-up, hammering operation
is difficult.
Be sure no one is below when using the tool in high locations.
5. Always be sure you have a firm footing.
6. Hold the tool firmly with both hands.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool only when hand-held.
9. Do not point the tool at any one in the area when operating. The bit could
fly out and injure someone seriously.
IO. When drilling or chippinginto 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 or chip into a "live" wire.
11. Do not touch the bit or parts close tothe bit immediately after operation;
they may be extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.

Reversingswitch action
This tool has
a reversing switch to change
the direction of rotation. Move the revers-
ing switch lever to the &> position for
clockwise rotation or the 4%) position for
counterclockwise.
CAUTION
:
*Always check the direction of rotation
before dril
I ing.
*Use the reversing switch only when the
tool comes to
a complete stop. Changing
the direction of rotation before the tool
stops may ruinthe tool.
Torque limiter
The torque limiter will actuate when
a certain torque level is reached. The motor will
disengage from the output shaft. When this happens,the bitwill stop turning.
CAUTION
:
*As soon as the torque limiter actuates, switch off the tool immediately. This will help
prevent premature wear of the tool.
0 Hole saws, core bits, diamond core bits, etc. cannot be used with this tool. They tend
to pinch or catch easily in the hole. This will cause the torque limiter to actuate too
frequently
.

Hammer drilling operation
*Position the bit at the location for the
hole, then pull the trigger.
Do not force the tool. Light pressure
gives best results. Keep the tool in posi-
tion and prevent it from slipping away
fromthe hole.
*Do not apply more pressure when the
hole becomes clogged with chips or par-
ticles. Instead, run the tool
at an idle,
then remove from the hole. By repeating
this several times, the holewill be cleaned
out.
Dust cup
Use the dust cup to preventdust from fall-
ing over the
tool and on yourself when
performing overhead drilling operations.
Attach the dust cup to the bit
as shown in
the figure. The dust cup can be attachedto
the bit upto 14.5 mm (9/16') in diameter.
Drilling in wood or metal
Use the optional drill chuck assembly (con-
sisting
of drill chuck, chuck adapter and
screw) for drilling up to 13mm
(1/2") in
metal and up to 18 mm (11/16") inwood.
To install it, refer to "installing or remov-
ingdrill bit".
