General Power Tool Safety Warnings

_ ARMNG! Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in

electric shock, fire and/or serious injury,

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

The term "power tool" in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.

1} WORK AREA SAFETY

a) Keep work area clean and well lit. Cluttered or dark areas

invite accidents.

b) Do not operate power tools in explosive atmospheres,

such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust or

fumes.

c) Keep children and bystanders away while operating a

power tooL Distractions can cause you to lose control

2) ELECTRICAL SAFETY

a) 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.

b) Avoid body contact with earthed or grounded surfaces

such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is earthed or

grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric
shock.

d) Do not abuse the cord. Never use the cord for carrying,

pulling or unplugging the power tooL Keep cord away

from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.

e) 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.

If operating a powertool in a damp location is unavoidable,
use a ground fault circuit interrupter (GFCI) protected
supply. Use of a GFC/ reduces the risk of electric shock.

3} PERSONAL SAFETY

a) 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
operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always wear eye

protection. Protective equipment such as dust mask, non-

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

c) Prevent unintentional starting. Ensure the switch is in

the off position before connecting to power source and/
or battery pack, picking up or carrying the tool Carrying

power tools with your finger on the switch or energizing power

tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the

power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in
unexpected situations.

Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from moving

parts. Loose clothes, jewelry or long hair can be caught in

moving parts.

g) If devices are provided for the connection of dust

extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can

reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a) 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.

b) Do not use the power tool if the switch does not turn it

on and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.

c) 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.

d) 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.

e) Maintain power tools. Check for misalignment or binding

of moving parts, breakage of parts and any other
condition that may affect the power tool's 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

g) Use the power tool, accessories and tool bits, etc. in

accordance with these instructions, 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.

5) BATTERY TOOL USE AND CARE

a) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type of

batterypackmaycreateariskoffirewhenusedwithanother
batterypack.

b)Use power tools only with specifically designated battery

packs. Use of any other battery packs may create a risk of

injury and fire.

c) 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. Shorting the battery terminals
together may cause bums or a fire.

d) Under abusive conditions, liquid may be ejected from

the battery; avoid contact. If contact accidentally occurs,
flush with water, tf liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause

irritation or bums.

6} SERVICE

a) Have your power tool serviced by a qualified repair

person using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

Additional Specific Safety Rules

= Hold power tool by insulated gripping surfaces when

performing an operation where the fastener may contact
hidden wiring. Fasteners contacting a "live" wire may make

exposed metal parts of the power tool "live" and could give the
operator an electric shock.

• Use clamps or other practical way to secure and support
the workpiece to a stable platform. Holding the work by hand

or against your body is unstable and may lead to loss of control
Wear safety goggles or other eye protection. Hammering and

drilling operations cause chips to fly. Flying particles can cause

permanent eye damage.

Accessories and tools get hot during operation. Wear gloves

when touching them.

Air vents often cover moving parts and should be avoided.

Loose clothes, jewelry or long hair can be caught in moving parts.
Do not operate this tool for long periods of time. Vibration

caused by too/action may be harmful to your hands and arms.
Use gloves to provide extra cushion and limit exposure by taking
frequent rest periods.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses

are NOT safety glasses. Also use face or dust mask if cutting
operation is dusty. ALWAYS WEARCERTIFIED SAFETY EQUIPMENT_

ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI $12.6 ($3. 19)hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

_,WARNING: Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities contains chemicals

known to the State of California to cause canced birth defects or other
reproductive harm. Some examples of these chemicals are:

lead from lead-based paints,
crystalline silica from bricks and cement and other masonry

products, and

arsenic and chromium from chemically-treated lumbe_
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:

work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to

filter out microscopic particles.

Avoid prolonged contact with dust from power sanding,

sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with

soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.

7/32" (5.5 mm) of the screw exposed.

important Charging Notes

1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65 °Fand
75 °F (18 °-24 °C). DO NOT charge the battery pack in an air

temperature below +40 °F (+4.5 °C), or above +104 °F(+40 °C).
This is important and will prevent serious damage to the battery

pack.

2. The charger and battery pack may become warm to the touch
while charging. This is a normal condition, and does not indicate

a problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment

such as in a metal shed or an uninsulated trailer.

3. A cold battery pack will charge at about half the rate of a warm
battery pack. The battery pack will charge at that slower rate

throughout the entire charging cycle and will not return to
maximum charge rate even if the battery pack warms.

4. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other

appliance;

b.Checktoseeifreceptacleisconnectedtoalightswitchwhich

Usage

Your impact tool can generate the following maximum torque values
(Speed 3, Speed 2, Speed 1).
NOTE: Output torque is dependent on the speed selected, with the
highest provided in Speed 3.

Ft.-Lbs. Nm

Cat # Speed 3/2/1 Speed 3/2/1

DCF897 700/300/100 950/400/130
DCF898 500/300/100 680/400/130

DCF899,DCF899H 700/300/100 950/400/130

i_ CAUTION: Ensure fastener and/or system will withstand the level

of torque generated by the tool Excessive torque may cause
breakage and possible personal injury.

1. Place the accessory on the fastener head. Keep the tool pointed
straight at the fastener.

2. Press switch to start operation. Release switch to stop operation.
Always check torque with a torque wrench, as the fastening
torque is affected by many factors including the following:

• Voltage: Low voltage, due to a nearly discharged battery, will
reduce fastening torque.

• Accessory size: Failure to use the correct accessory size will
cause a reduction in fastening torque.

• Bolt size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according to
length, grade, and torque coefficient.

DCF898

13

• Bolt: Ensure that all threads are free of rest and other debris to
allow proper fastening torque.

Material: The type of material and surface finish of the material
will affect fastening torque.

Fastening time: Longer fastening time results in increased
fastening torque. Using a longer fastening time than recom-

mended could cause the fasteners to be overstressed,
stripped or damaged.
