GENERAL SAFETY RULES
(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
READ ALL INSTRUCTIONS.
WORK AREA
1. Keepyour work area clean and well lit. Cluttered benches and dark areas invite
accidents.
2. Donotoperate power tools in explosiveatmospheres, suchas 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 operating a power tool.
Distractions can cause
you to lose control.
ELECTRICALSAFETY
4. Double Insulatedtools areequipped witha polarized plug(oneblade iswider
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 does not fit,
contact a qualified electrician to install a polarized outlet. Do not change
the plug
in any way. Double insulation eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid body contact with grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
6. Do not expose power tools torainor wet conditions. Water entering a power
tool
will increase the risk of electric shock.
7. Do notabuse the cord. Never use the cord tocarry the tools or pullthe plug
from an outlet. Keepcord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. When operatinga power tool outside, useanoutdoor extensioncord marked
"W-A" or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
PERSONAL SAFETY
9. Stay alert, watchwhat you are doing andusecommonsense whenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A moment of inattention while operating powertools
may result in serious personal injury.
IO. Dressproperly. Donotwear loose clothingorjewelry. Containlong hair. Keep
your hair, clothing, andglovesaway from movingparts. Looseclothes, jewelry
or long hair can be caught in moving parts.
2

11. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools withyour finger onthe switchor plugging intools that have the switch
on invites accidents.
12. Remove adjusting keys or wrenches before turning the tool on. A wrench
or a key that
is left attachedto a rotating part of the tool may result inpersonal
injury.
13. Donotoverreach. Keep proper footing andbalanceat alltimes. Proper footing
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 stable platform. Holdingthe work by handor against your body is unstable
and may lead to
loss of control.
16. Do not force 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. Disconnect the plugfrom the power 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 main-
tained tools.
22. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool, may becomehazardous
when used on another tool.
SERVICE
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 identicalreplacement parts. Follow instruc-
tions in
the Maintenance section of this manual. Use of unauthorized parts
or failure to follow Maintenance Instructionsmay create a risk of electric shock
or injury.

SPECIFIC SAFETY RULES FOR ROTARY HAMMER
1. Hold tools by insulated gripping surfaces when performing an operation
where the cutting tool may contact hidden wiring or itsown cord. Contact
with a "live" wire will make exposed metal parts of the tool "live" and shock
the operator.
2. Wear ear protectors when using the tool for extended periods. Prolonged
exposure to high intensity noise can cause hearing
loss.
3. Wear a hardhat (safety helmet), safety glasses andlor face shield. It isalso
highly recommended that you wear a dust mask and thickly padded gloves.
4. Be sure the bit is secured in place before operation.
5. Undernormaloperation, the toolisdesignedtoproducevibration. Thescrews
can come loose easily, causing a breakdown or accident. Check tightness
of screws carefully before operation.
6. In cold weather or when the tool has not been 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.
7. Always be sure you have a firm footing.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
IO. Do not leave the tool running. Operate the tool only when hand-held.
11. Do not point the tool at any one in the area when operating. The bit could

OPERATION
Hammer drilling operation
CAUTION:
When the bit begins to break through concrete or if the bit strikes reinforcing rods em-
bedded in concrete, the tool may reactdangerously.Maintaingood balanceand safefoot-
ingwhile holdingthe tool firmly with both hands
to preventdangerous reaction.
Set the change lever and the shift lever to
thevlsymbol. Position the bit
at the loca-
tion for the hole, then pull the trigger.
Do
not force the tool. Light pressure gives
best results. Keep the tool in position and
prevent it from slipping away from the
hole.
Do not apply more pressurewhen the hole
becomes clogged with chips or particles.
Instead, run the tool at an idle, then
remove from the hole.
By repeating this
severaltimes, the holewill becleaned out.
Torque limiter
The torque limiter will actuate when a certain torque level is reached.The motor will dis-
engage 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 helppre-
vent premature wear of the tool.
Chipping/Scaling/Demolition
Set the change lever and the shift lever to
the symbol. Holdthe tool firmly with both
hands. Turn the tool
on and apply slight
pressure on the tool
so that the tool will
not bounce around, uncontrolled. Pressing
very hard on the tool
will not increase the
efficiency.

Drillingoperation
Set the change lever and the shift lever to the 1 symbol.
Drillinginwood
When drilling in wood, best results are obtainedwith wood drills equippedwith
a guide
screw.The guide screw makes drillingeasier by pullingthe it intothe workpiece.
To preventthe bit from slipping when starting
a hole, make an indentationwith a center-
punchand hammer at the pointto the drilled. Place the pointof the bit in the indentation
and start drilling.
Use
a cutting lubricant when drilling metals. The exception are iron and brass which
shouldbe drilleddry.
Drillingin metal
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 performanceand
shortenthe service life of the tool.
