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.

f. If operating a power tool in a damp

location is unavoidable, use a Ground

Fault Circuit Interrupter (GFCI)

protected supply. Use of an GFCI

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

Read all safety warnings, instructions, illustrations and speciﬁcations

provided with this power tool. Failure to follow all instructions listed below

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.

General Power Tool Safety Warnings

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 a 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.

f. Dress properly. Do not wear loose

clothing or jewelry. Keep your hair and

clothing 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.

h. Do not let familiarity gained from

frequent use of tools allow you to

become complacent and ignore tool

safety principles. A careless action can

cause severe injury within a fraction of a

second.

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 remove the battery pack,

if detachable, 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 and accessories.

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.

f. 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.

h. Keep handles and grasping surfaces dry,

clean and free from oil and grease.

Slippery handles and grasping surfaces

do not allow for safe handling and control

of the tool in unexpected situations.

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

battery pack may create a risk of fire

when used with another battery pack.

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

2610067376 08-21 GDS18V-740C.qxp_GDS18V-770 8/18/21 7:00 AM Page 4

a. Hold the 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.

b. Use clamps or another practical way to

secure and support the workpiece to a

stable platform. Holding the work by

hand or against your body leaves it

unstable and may lead to loss of control.

c. Do not drive fasteners into existing walls

or other blind areas where electrical

wiring may exist. If this situation is

unavoidable, disconnect all fuses or circuit

breakers feeding this worksite.

d. Use only sockets designed for power

impact wrenches. Sockets designed for

hand use may break under the load this

tool generates.

e. Be certain to seat the socket completely

and securely on the output drive.

f. Do not use worn or damaged sockets.

g. Select the correct size sockets and keep

the inside of the socket clean.

h. Do not allow a loose fastener to spin

freely within the socket. The fastener

may be thrown out of the socket.

i. Use thick cushioned gloves and limit the

exposure time by taking frequent rest

periods. Vibration caused by impact driver

action may be harmful to your hands and

arms.

j. Remove battery pack before changing

accessories. Accidental starting may

occur because battery appliances with a

battery inserted are in the operative

condition.

k. Be prepared for a reaction torque when

“seating” or removing a fastener. The

tool housing may tend to twist in the

opposite direction of accessory rotation

when “seating” or removing a fastener

depending on the torque setting of the

tool.

l. Do not run the tool while carrying it at

your side. The rotating drive could

become entangled with clothing and

injury may result.

m. Place the tool onto the fastener only

when the tool is switched off. Rotating

driver tools can slide off the fastener.

Safety Rules for Cordless Impact Wrenches

make a connection from one terminal to

another. Shorting the battery terminals

together may cause burns or a fire.

d. Under abusive conditions, liquid may be

ejected from the battery, avoid contact.

If contact accidentally occurs, flush

with water. If liquid contacts eyes,

additionally seek medical help. Liquid

ejected from the battery may cause

irritation or burns.

e. Do not use a battery pack or tool that is

damaged or modified. Damaged or

modified batteries may exhibit

unpredictable behavior resulting in ﬁre,

explosion or risk of injury.

f. Do not expose a battery pack or tool to

ﬁre or excessive temperature. Exposure

to ﬁre or temperature above 265 °F may

cause explosion.

g. Follow all charging instructions and do

not charge the battery pack or tool

outside the temperature range

specified in the instructions. Charging

improperly or at temperatures outside

the specified range may damage the

battery and increase the risk of ﬁre.

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.

b. Never service damaged battery packs.

Service of battery packs should only be

performed by the manufacturer or

authorized service providers.

Additional Safety Warnings

a. GFCI and personal protection devices like

electrician’s rubber gloves and footwear

will further enhance your personal safety.

b. Develop a periodic maintenance schedule

for your tool. When cleaning a tool be

careful not to disassemble any portion of

the tool since internal wires may be

misplaced or pinched or safety guard

return springs may be improperly

mounted. Certain cleaning agents such as

gasoline, carbon tetrachloride, ammonia,

etc. may damage plastic parts.

c. Ensure the switch is in the off position

before inserting battery pack. Inserting

the battery pack into power tools that

have the switch on invites accidents.

Some dust created by

power sanding, sawing,

grinding, drilling, and other construction

activities contains chemicals known to cause

cancer, 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 lumber.

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.

Intended Use

This tool is intended for

the tightening and

loosening of bolts, nuts and various

threaded fasteners. This tool is not

intended for use as a drill.

Variable Speed Controlled

Trigger Switch

Your tool is equipped with a variable speed

trigger switch. The tool can be turned "ON"

or "OFF" by squeezing or releasing the

trigger. The speed can be adjusted from the

minimum to maximum nameplate RPM by

the pressure you apply to the trigger. Apply

more pressure to increase the speed and

release pressure to decrease speed (Fig. 1).

Brake

When the trigger switch is released it

activates the brake to stop the chuck

quickly. This is especially useful in the

repetitive driving and removal of screws.

Forward/Reversing Lever

and Trigger Lock

After tool use, lock

trigger in “OFF”

position to help prevent accidental starts

and accidental discharge.

Do not change direction

of rotation until the tool

comes to a complete stop. Shifting during

rotation of the chuck can cause damage to

the tool.

Your tool is equipped with a forward/

reversing lever and trigger lock (3) located

above the trigger (Fig. 10). This lever was

designed for changing rotation of the

socket, and for locking the trigger in an

“OFF” position.

To lock the trigger, move the lever to the

center.

For forward rotation, (with chuck pointed

away from you) move the lever to the far

left.

For reverse rotation move the lever to the

far right. To activate trigger lock move lever

to the center off position.

Built-in work light

Your tool is equipped with an LED light

(13) for better visibility when using the

tool.

After the trigger (8) is activated, the LED

will then stay on for 10 seconds. The length

of time for afterglow can be changed in

‘Bosch ToolBox’ app setting (if connected).

Operating tips

You will extend the life of your bits and do

neater work if you always put the bit in

contact with the work before pulling the

trigger. During the oper a tion, hold the tool

firmly and exert light, steady pressure. Too

much pressure at low speed will stall the

tool. This can be damaging to both tool

and bit.

Driving with variable speed

The technique is to start slowly, increasing

the speed as the screw runs down. Set the

screw snug ly by slowing to a stop. Prior to

driving screws, pilot and clearance holes

should be drilled.

Operating Instructions

Always hold the tool straight on the bolt to

be tightened.

The best method to determine the right

impacting/tightening duration is by means

of a trial. For small screws, the right

impacting/ tightening duration can be

reached in less than 0.5 Sec. Therefore,

work with low RPM and switch the tool off

immediately when the screw is tight and

the impacting sound can be heard.

For screwing larger, longer wood screws

into hard material, pre-drilling is the best

method.

Tightening Torque

The tightening torque depends on the

duration of the impacting/tightening action.

The largest tightening torque is achieved

after approx. 6 to 10 Sec. impacting /

tightening action.

The torque build-up depends on the

following factors:

• Hardness of the bolts/nuts.

• Type of washer (disk washer, spring

washer, seal).

• Hardness of the material to be joined.

• Lubricating effect at the surfaces of the

junction.

This leads to the following application

cases:

Hard joining application: The joining of

metal to metal with a disk washer. The

maximum torque is reached after a relative

short impacting/tightening action.

Medium joining application: The joining of

metal to metal when using spring ring

washer, disk spring washer, stud bolts or

bolts/nuts with conical seats.

Soft joining application: The joining of e.g.

metal to wood or insulation material.

For middle or soft joining cases, the

maximum tightening torque is less than for

hard cases. Therefore, a longer

impacting/tightening action is necessary to

arrive at the maximum tightening torque.

Selecting the working mode

The power tool has two preset working

modes: A and B (17). You can also program

working modes for different applications

and adjust existing modes via the Bosch

Toolbox under A and B.

To switch between the working modes A

and B (17), press the Mode button (16).

By Default Mode A is designed for Self-

Drilling Screws. Auto Slow Down is

activated in both the forward and reverse

directions.

By Default Mode B is designed for Wood

Screws. In the forward direction Auto Shut-

off is activated. In the reverse direction

Auto Shut Off functions as Auto-Bolt

Release for the default Mode B.

Note: Only one Setting or Mode can be

active on the tool at a time. 1, 2, 3, A, or B.

Fastening with screws

The procedure shown in (Fig. 11) will help

to fasten ma terials together with your tool

and will reduce the possibility of stripping,

splitting or separating the material.

First, clamp the pieces together and drill

the first hole 2/3 the diam eter of the

screw. If the material is soft, drill only 2/3

the proper length. If it is hard, drill the

entire length.

Second, unclamp the pieces and drill the

second hole the same diameter as the

screw shank in the first or top piece of

wood.

Third, if flat head screw is used,

countersink the hole to make the screw

flush with the surface. Then, simply apply

even pressure when driving the screw. The

screw shank clearance hole in the first

piece allows the screw head to pull the

pieces tightly together.

2. Drill same

diameter as

screw shank.

3. Countersink

same diameter

as screw head.

1. Drill 2/3 diameter and

2/3 of screw length for

soft materials, full

length for hard

materials.

Screw

Apply a slight

even pressure

when driving

screws.

Driving nuts and bolts

Use variable speed control with caution for

driving nuts and bolts with socket

attachments. The technique is to start

slowly, increasing speed as the nut or bolt

runs down. The nut or bolt is set when the

socked comes to a stop.

Note: Ensure that no metal particles enter

the power tool. After working at a low

speed for an extended period, you should

operate the power tool at the maximum

speed for approximately three minutes

without load to cool it down.

Cold weather use (32°F)

Due to the lubrication used in the

impacting mechanism, the tool should be

run for three minutes at no load prior to

actual usage. This will warm the lubricant

and provide better performance.

User interface

Status indicator LED

The LED bar at the top of the user interface

illuminates in various colors to help the

user identify the status of the tool. When

the status indicator LED (12) is green, the

tool and battery pack are operating

normally and temperatures are ok. If the

indicator changes to yellow, it means that

the tool or battery temperatures have risen

to a high level, and the use of the tool must

stop to allow the tool to cool off. It is best

to back off the load and give the tool

chance to cool down. If the indicator turns

red, the tool will shut off to protect itself

and/or the battery pack from an

overheating situation.

The status indicator LED (12) will also blink

blue when the speed (14) or mode (16)

buttons are held for 7 seconds. This will

reset the tool settings to factory default.

Joist Hanger

When using the joist

hanger always be aware

that the accessory is exposed. Always hang

the tool in an area where yourself and

bystanders cannot accidently make contact

with the accessory.

To reduce the risk of

injury, Do not use the

joist hanger if it appears damaged or

deformed. This could result in unstable

hanging and the tool unexpectedly falling.

To reduce the risk of

injury, use care in

selecting the location for hanging the tool.

The optional joist hanger accessory (4) will

allow you to conveniently attach your tool

to a joist, or other convenient support

when not in use.

The joist hanger (4) can be attached to

either side of the tool by securing it with a

mounting screw. Always make sure you

securely tighten the mounting screw before

use (Fig.1).

• Select a suitably sized and shaped object

that will provide adequate hanging

stability. An unstable hanging surface

could result in the tool unexpectedly

falling.

• Ensure that the tool is hung out of the way

of walkways and working areas with

bystanders. The tool could be bumped or a

bystander could become entangled

causing the tool to unexpectedly fall.
