unplugging the power tool. Keep
cord away from heat, oil, sharp
edges or moving parts.

Damaged or entangled cords in-

crease the risk of electric shock.

5)

When operating a power tool out­doors, use an extension cord suit­able for outdoor use.

Use of a cord suitable for outdoor use
reduces the risk of electric shock.

WARNING! Read all instructions

Failure to follow all instructions listed below
may result in electric shock, fire and/or
serious injury. The term “power tool” in all
of the warnings listed below refers to your
main operated (corded) power tool and
battery operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work Area Safety

1) Keep work area clean and well lit.
Cluttered or dark areas invite acci-

dents.

2) Do not operate power tools in ex-

plosive atmospheres, such as in
the presence of flammable liq­uids, gases or dust.

Power tool plugs must match the
outlet. Never modify the plug in any
way. Do not use any adapter plugs
with earthed (grounded) power tools.

Unmodified plugs and matching out­lets will reduce risk of electric shock.

Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators.

There is an increased risk of elec-

tric shock if your body is earthed or
grounded.

rain or wet conditions.

Water entering a power tool will in-

crease the risk of electric shock.

Personal Safety

1) Stay alert, watch what you are

doing and use common sense
when operating a power tool. Do
not use a power tool while you
are tired or under the influence of
drugs, alcohol or medication.

A moment of inattention while oper-

ating power tools may result in per­sonal injury.

2) Use safety equipment. Always

wear eye protection.

Safety equipment such as dust

mask, non-skid safety shoes, hard
hat, or hearing protection used for
appropriate conditions will reduce
personal injuries.

3) Avoid accidental starting. Ensure

the switch is in the off position
before plugging in.

Carrying power tools with your fin-

ger on the switch or plugging in the
power tools that have the switch on
invites accidents.

4)

6)

7) Use the power tool, accessories

Do not force the power tool. Use
the correct power tool for your
application.

The correct power tool will do the

job better and safer at the rate for
which it was designed.

2)

Do not use the power tool if the
switch does not turn it on and off.

Any power tool that cannot be con-

trolled with the switch is dangerous
and must be repaired.

Disconnect the plug from the pow­er source and/or the battery pack
from the power tool before making
any adjustments, changing acces­sories, or storing power tools.

Such preventive safety measures

reduce the risk of starting the pow­er tool accidentally.

Store idle power tools out of the
reach of children and do not al­low persons unfamiliar with the
power tool or these instructions
to operate the power tool.

Power tools are dangerous in the

hands of untrained users.

5) Maintain power tools. Check for

misalignment or binding of mov­ing parts, breakage of parts and
any other condition that may af­fect the power tools operation. If
damaged, have the power tool re­paired before use.

Many accidents are caused by

poorly maintained power tools.

Keep cutting tools sharp and clean.

Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.

and tool bits etc. in accordance
with these instructions and in the
manner intended for the particu­lar type of power tool, taking into
account the working conditions
and the work to be performed.

Use of the power tool for operations
different from those intended could
result in a hazardous situation.

Battery Tool Use and Care

1)

Ensure the switch is in the off posi­tion before inserting battery pack.

Inserting battery pack into pow-

er tools that have the switch on in­vites accidents.

A charger that is suitable for one type
of battery pack may create a risk of fire
when used with another battery pack.

3) Use power tools only with specif-

ically designated battery packs.

Use of any other battery packs may

create a risk of injury and fire.

4)

5) Under abusive conditions, liq-

When battery pack is not in use,
keep it away from other metal ob­jects like paper clips, coins, keys,
nails, screws, or other small metal
objects that can make a connection
from one terminal to another .

Common Cautions for the Li­ion/Ni-MH/Ni-Cd Battery Pack

• The ambient temperature range is be­tween 0°C (32°F) and 40°C (104°F).

If the battery pack is used when the

battery temperature is below 0°C

(32°F), the tool may fail to function

properly.

• Use the charger at temperatures be­tween 0°C and 40°C, and charge the
battery at a temperature similar to that
of the battery itself. (There should be
no more than a 15°C difference be­tween the temperatures of the battery
and the charging location.)

• When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place
and wait for more than one hour to
warm up the battery to the level of
the ambient temperature.

Cool down the charger when charging

•
more than two battery packs consecu­tively.

• Do not insert your fingers into contact
hole, when holding charger or any
other occasions.

CAUTION:

To prevent the risk of fire or damage
to the battery charger.

• Do not use power source from an
engine generator.

• Do not cover vent holes on the
charger and the battery pack.

• Unplug the charger when not in
use.

. USAGE SUGGESTION

1. If there isn’t enough force pushing down on the bit, the tool may not be able to

blow in hammering mode.

This is to prevent the hammering mode from operating with no load. Press down

harder on the bit to engage the tool and cause it to blow .

Always be sure to press down with enough force when working.

2. In winter or in other situations where the temperature of the unit is low (5°C (41°F)

or below), the blow of the hammering mode may be weaker than normal at the
beginning stage.

This is because the grease becomes stiffer in low temperatures, increasing fric-

tion.

If this should happen, operating hammering mode with no load for approximately

30 seconds and repeat this 3 times. This will restore its blowing power.
