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 should bestored indry, and high
or locked-up place
- out of reach of children.
DON'T FORCETOOL.
It will dothejob better and safer atthe ratefor which
it was intended.
USE RIGHT TOOL. Don't force small tool or attachment to do the job
of a
heavy-duty tool. Don't usetoolfor purpose not intended; for example, don't
use circular saw for cutting tree limbs or logs.
DRESS PROPERLY. Don't wear loose clothing or jewelry. They canbecaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when workingoutdoors. 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 cordor 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 tool cords periodicallyandifdamaged, haverepairedby autho-
rized service facility. Inspect extension cords periodically and replace
if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. 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 to
see that keysand adjusting wrenches are removed from tool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger onswitch.
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
inline voltage resulting in
loss of power and overheating. Table 1 shows the
correct size touse depending oncord lengthand nameplate ampere rating.
If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

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 tothe user - as well as damage to
the tool. If in doubt, DO NOT PLUG INTHE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.
ADDITIONAL SAFETY RULES

CAUTION:
0 Always check the direction of rotationbefore operation.
*Use the reversing switch only after the tool comes to
a complete stop. Changing the
direction of rotation before the tool stops may damage the tool.
Operation
Place the point of the driver bit in the screw head. Apply forward pressureto the tool to
the extent that the bit will not slip off the screw. Start the tool slowly and then increase
the speed gradually.
Release the trigger just as the screw bottomsout. The proper fasten-
ing torque differs depending upon the kind or
size of screws/bolts,the type of materials
to be fastened, etc. Refer to the figure below for the relation between fasteningtime and
wood screw size.

NOTE :
0 Use the proper bit for the head of the screw/bolt that you wish to use.
.When fastening machine screws in
a steel plate, the proper fastening torque can be
obtained in an extremely short time (approx.
0.1 - 0.2 seconds). Turn the tool off as
soon as the impact sound is heard.
0 Hold the tool pointed straight at the screw or the screw and/or bit may be damaged.
.When driving wood screws, predrill pilot holes to make driving easier and to prevent
splitting of the workpiece. The pilot holes should be slightly smaller than the wood
screws in diameter.
.The
size of wood screw which can be fastened with this tool may differ dependingupon
the type of material to be fastened. Always perform
a test operation to determine the
size of wood screw.
.When fastening bolts or nuts, always perform
a test operation to verify the adequate
fastening time for your bolt or nut. Excessive fasteningtorque may damage the bolt/nut
or socket bit.
