(For All Tools)
WARNING:
WHEN USING ELECTRICTOOLS, BASICSAFETY
PRECAUTIONSSHOULD ALWAYS
BE FOLLOWEDTO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
1. KEEPWORK AREA CLEAN. Clutteredareas and benchesinviteinjuries.
2. CONSIDERWORK AREA ENVIRONMENT. Don’t usepowertools
in dampor
wet locations. Keep work area well lit. Don’t expose power tools to rain.
Don’t usetool in presenceof flammable liquids or gases.
3. KEEP CHILDREN AWAY.
All visitors should be kept away from work area.
Don’t let visitors contact tool or extensioncord.
4. STORE IDLETOOLS. When not in use, tools should be stored in dry, and
high or locked-upplace
- out of reachof children.
5. DON’T FORCETOOL. Itwill do the job betterand safer at the ratefor which
itwas intended.
6. USE RIGHTTOOL. Don’t force small tool or attachment to do the job of a
heavy-dutytool. Don’t usetool for purposenot intended;for example,don’t
usecircular saw for cutting tree limbs or logs.
7. DRESS PROPERLY. Don’twear looseclothing orjewelry.They canbecaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protectivehair coveringtocontain long hair.
8. USE SAFETY GLASSES. Also useface or dust mask if cutting operation is
dusty.
9. DON’T ABUSE CORD. Never carrytool bycord or yank ittodisconnectfrom
receptacle. Keepcord from heat, oil, and sharp edges.
10. SECURE WORK. Use clamps or a vise to hold work. It’s safer than using
your handand it frees both hands to operatetool.
11. DON’T OVERREACH. Keep proper footing and balanceat all times.
12. MAINTAINTOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructionsfor lubricating and changingacces-
sories. Inspect tool cords periodically and if damaged, have repaired by
authorizedservicefacility. Inspectextensioncords periodicallyand replace
if damaged. Keep handles dry, clean, and freefrom oil and grease.
13. DISCONNECTTOOLSwhen not

14. REMOVEADJUSTING KEYS AND WRENCHES. Form habit of checking to
seethat keysandadjustingwrenches are removedfromtoolbeforeturning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger on switch.
Be sure switch is
OFF when plugging in.
16. EXTENSIONCORDS. 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
inline voltage resulting
in loss of powerandoverheating. Table 1 showsthe
correct size touse depending on cord lengthand nameplateampere rating.
If in doubt, use the next heavier gauge. The smaller the gauge number, the
heavierthecord.

extension cords intended for use outdoors and
so marked.
18. STAY ALERT. Watch what youaredoing, usecommonsense. Don't operate
tool when you are tired.
19. CHECK DAMAGEDPARTS. 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, 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
service center unless otherwise indicated elsewhere in this instruction
manual. Havedefective switchesreplacedbyauthorizedservicecenter.Don't
use tool
if switch does not turn it on and off.
20. GUARDAGAINST ELECTRICSHOCK. Preventbody contactwith grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21. REPLACEMENTPARTS. When servicing, useonlyidenticalreplacementparts.
22. POLARIZEDPLUGS. To reducethe risk of electric shock, thisequipment 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,
reversethe plug. If
it stilldoesnot fit, contactaqualifiedelectriciantoinstall
the proper outlet. Do not change the plug in any way.

VOLTAGE WARNING: Beforeconnectingthe tool to apower source (receptacle,
outlet, etc.) be sure the voltage supplied is
the same as that specified on the
nameplateof the
tool. A power source withvoltage greater than that specified
for the tool can result
in SERIOUS INJURYto 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.
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!
Holdthe
tool by the insulatedgrasping surfacesto prevent electric shock if
you drill into a "live" wire.
Be sure no one is below when using the tool
in high locations.
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.

Installingor removing drill bit
CAUTION :
Always be sure that the tool is switched off and unplugged before installing or removing
the bit.
Hold the ring
and turn the sleeve counter-
clockwise to open the chuck jaws. Place
the bit in the chuck
as far as it will go.
Hold the ring firmly and turn the
sleeve
clockwise to tighten the chuck.
To remove the bit, hold the ring and turn
the
sleeve counterclockwise.
Switch action

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.

Reversing switch action
The reversing switch changes the direction
of rotation.
Move the reversing switch lever to the
"FWD" position for clockwise rotation.
Move the reversing switch lever
to the
"REV" position for counterclockwise rota-
tion.
The switch trigger does not actuate if the
reversing switch lever
is inthe neutral posi-
tion.
CAUTION
:
0 Before plugging inthe tool, always check to see that the switch trigger actuates properly
0 Always check the direction of rotation beforedrilling.
0 Use the reversing switch lever only when the tool comes to a complete stop. Changing
When not operating the tool, keep the reversing switch lever inthe neutral position.
.Pulling the trigger hard when the reversing switch lever
is in the neutral position can

cause switch breakage.

Drilling operation
0 Drillinginwood
When drilling holes in the wood, use
a wood drill with a guide screw, The guide screw
makes
it bore naturally by itself, so you do not need to apply any pressureto the tool.
0 Drilling inmetal
To prevent the bitfrom slipping when starting a hole, makean indentation with a center-
punch and hammer
at the point to be drilled. Place the point of the bit inthe 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 at the time of hole break through.
Hold the tool firmly and exert care,when the bitbegins to break through the workpiece.
0Always grip the small workpiece firmly with
a vise or a holding means.
0A 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.

Always be sure that the tool is switched off and unpluggedbeforeattemptingto perform
inspectionor maintenance.
To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspectionand
