GENERAL SAFETY RULES USA0021
(For All Tools)
WARNING! Read and understand all instructions. Failure
to follow
all instructions listed below, may result in electric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work areacleanand well lit. Clutteredbenches and dark areas invite
accidents.
2. Do notoperate powertools in explosiveatmospheres, such as in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operatinga power tool.
Distractions can cause
you to lose control.
Electrical Safety
4. DoubleInsulatedtools areequipped witha polarized plug(oneblade iswider
than the other.) This
plug will fit in a polarized outlet only one way. Ifthe
plug does not fit fully
in the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a polarized outlet.
Do not change
the plug
in any way. Double insulation El eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid body contact withgrounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
6. Donotexpose powertools torainor wet conditions. Water enteringa power
tool
will increase the risk of electric shock.
7. Do notabuse the cord. Never use the cordtocarry the tools or pullthe plug
from
an outlet. Keepcordaway fromheat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. When operating a powertooloutside, use an outdoorextension cordmarked
"W-A' or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
Personal Safety
9. Stay alert, watchwhat youaredoing and usecommon sensewhenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A moment of inattentionwhile operating power tools
may result
in serious personal injury.
IO. Dressproperly. Donotwear loose clothing orjewelry. Contain longhair. Keep
your hair, clothing, andglovesaway from movingparts. Looseclothes,jewelry
or long hair can be caught
in moving parts.

11. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools
with your finger onthe switchor plugging in tools that have theswitch
on invites accidents.
12. Remove adjusting keys or wrenches before turning the tool on. A wrench
or a key that is left attachedtoa rotating partof thetool may result
in personal
injury.
13. Donotoverreach. Keepproper footingandbalance at all times. Properfooting
and balance enables better control of the tool
in unexpected situations.
14. Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat,
or hearing protection must be used for appropriate
conditions.
Tool Use and Care
15. Use clamps or other practical way to secure and support the workpiece to
a stableplatform. Holdingthe work by handor against your body is unstable
and may lead to loss of control.
16. Do notforce tool. Usethe correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
17. Do not use tool if switch does not turn
it on or off. Any tool that cannot
be controlled
with the switch is dangerous and must be repaired.
18. Disconnectthe plugfromthepower source before makingany adjustments,
changing accessories,
or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
19. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cutting edges are less likely tobindand are easier
to control.
21. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tools operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly
maintained tools.
22. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitablefor one tool, may becomehazardous
when used on another tool.
S ERVl C E
23. Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of
injury.
24. When servicing a tool, use only identical replacement parts. Follow
instructions
in the Maintenancesectionof this manual. Use of unauthorized
parts or failure
to follow MaintenanceInstructionsmaycreate a riskof electric
shock or injury.

Specific Safety Rules
1. Holdtool by insulated grippingsurfaceswhen performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with a
"live" wire will make exposed metal parts
of the tool "live" and shock the
operator.
Be sure no one is below when using the tool in high locations.
2. Always be sure you have a firm footing.
3. Hold the tool firmly.
4. Keep hands away from rotating parts.
5. Do nottouch the bit or the workpiece immediately after operation: they may
be extremely hot and could burn your skin.

Hook
The hook is convenientfor temporaw hangingthe tool. When using the hook, pull it out in
"A" directionand then push it in B directionto securein place.
When not using the hook, return
it back to its initialposition by followingthe above proce-
dures in reverse.
Depth adjustment
Whenyou wish to drive self drillingscrews,
etc., adjust the depth as follows. Turn the
locator to adjust the depth.
Initially, adjust the locator to create
a distance of approximately 1 mm (3/64") from the tip
of the front cap (whichworks in conjunction with the locator) to the base
of the screw
head. Onefull turn of the locator equals 1 mm (3/64") change indepth. After adjustingthe
locator, turn the adjusting ring
so that the 6" mark is aligned with the pointer on the gear
housing. Drive a trial screw into your material or a piece of duplicate material. If the depth
is not suitable for the screw, continueadjusting untilthe proper depthsetting is obtained.

Adjusting fasteningtorque
When you wish to drive machine screws,
wood screws, hex bolts etc. with the pre-
determined torque, adjust the fastening
torque as follows.
The fastening torque may be adjusted by
turning the adjusting ring. Before turning
the adjusting ring, turn the locator in the
direction of the arrow as far as it will go
without forcing. The torque
is increased by
turning the adjusting ring in the directionof
the arrow anddecreased by turning it inthe
opposite direction. Align the number
1 on
the adjusting ring with the pointer on the

coulddamage a workpieceor cause an injury.
*Make sure thatthe bit is insertedstraight inthe screw head, or the screw andlor bit may
be damaged.
NOTE:
*Make sure that the driver bit is insertedstraight inthe screw head, or the screw andlor
bit my be damaged.
*When driving wood screws, predrill pilot
holes to make driving easier and to pre-
vent splitting of the workpiece. See the
