it was intended.
6. USE RIGHT TOOL. Don't force small tool or attachment t o do the job of a
heavy-duty tool. Don't use tool for purpose not intended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught
i n moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering t o 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 t o operate tool.
1 1 . 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 accessories. Inspect tool cords periodically and if damaged, have repaired by authorized 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 changing 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 UNINTENTIONAL STARTING. Don't carry tool w i t h finger on switch.
Be sure s w i t c h 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 t o 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 service 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 w i t h grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENT PARTS. 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 f i t in a
polarized outlet only one way. If the plug does not f i t fully in the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician t o 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 w i t h voltage greater than that specified
for the tool can result in SERIOUS INJURY t o the user - as well as damage t o
the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source w i t h
voltage less than the nameplate rating is harmful t o the motor.

Operation
1 ) Hammer drilling operation
When drilling in concrete, granite, tile, etc., press the action mode changing button on
the
mark side fully. Position the adjusting ring so that the pointer points to the
mark. Be sure to use a tungsten-carbide tipped bit. To position a hole accurately,
start the tool slowly and then increase the drilling speed gradually. Do not apply more
pressure when the hole becomes clogged with chips or particles. Instead, run the tool
a t an idle, then remove the bit partially from the hole. By repeating this several times,
the hole will be cleaned out.
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.
9
After drilling the hole, use the blow-out
bulb to clean the dust out of the hole.
2) Drilling operation
When drilling in wood, metal or plastic materials, press the action mode changing
button on the a== mark side fully. Position the adjusting ring so that the pointer
points to the 6-q mark.

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.
Drilling in metal
To prevent the bit from slipping when starting a hole, make an indentation with a
centerpunch and hammer a t the point to be drilled. Place the point of the bit in the
indentation 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.
0 There is a tremendous twisting force exerted on the tool/bit a t the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to breakthrough the
workpiece.
0 A stuck bit can be removed simply by setting the reversing switch to reverse rotation
in order to back out. However, the tool may back out abruptly if you do not hold it
firmly.
0 Always secure small wokpieces in a vise or similar hold-down device.

3) Screwdriving operation
When driving wood screws or machine
screws, press the action mode changing
button on the a== mark side fully.
Adjust the desired torque by turning the
adjusting ring. Place the point of the
driver bit into the screw head and apply
pressure to the bit. Start the tool slowly
and then increase the driving speed
gradually. Release the trigger as soon as
the clutch slips.
