Safety Instructions

General Power Tool Safety Warnings

WARNING: 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.

Work area safety

Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

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 electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
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.
When operating a power tool outdoors, use an exten-sion cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock..
If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety

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 per-sonal injury.
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.
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 energising power tools that have the switch on invites accidents.
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.
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, jewellery or long hair can be caught in moving parts.
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.

Power tool use and care

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.
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.
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.
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.
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.

Battery tool use and care

Recharge only with the charger specified by the manu-facturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
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 burns or a fire.
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.

Service

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.

Nailer safety warnings

Always assume that the tool contains nails. Careless handling of the nailer may result in unexpected firing of nails and personal injury.
Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge the nails causing an injury.
Do not actuate the tool unless the tool is placed firmly against the workpiece. If the tool is not in contact with the workpiece, the nail may be deflected away from your target.
Disconnect the tool from the power source when the nail jams in the tool. While removing a jammed nail, the nailer may be accidentally activated if it is plugged in.
Use caution while removing a jammed nail. The mech-anism may be under compression and the nail may be forcefully discharged while attempting to free a jammed condition.

Additional safety information for GNB 18V-38:

Do not use this nailer for fastening electrical cables. It is not designed for electric cable installation and may damage the insulation of electric cables thereby causing electric shock or fire hazards.

Additional Safety Information for GNB 18V-40:

When fastening electrical cables, make sure the cables are not energized. Hold the nailer only by insulated gripping surfaces. Use only nails designed for electrical cable installations. Inspect that the nails has not damaged the insulation of the electrical cables. A nail that damages the insulation of electric cables can lead to electric shock and fire hazards.
Disconnect the nailer from the power source when loading and unloading nails, making adjustments or changing accessories. The nailer may be accidentally activated if it is connected to the power source, which may result in personal injury.
Be careful when handling nails, especially when loading and unloading. The nails have sharp points which may result in personal injury.
Keep fingers away from trigger when not operating this nailer and when moving from one operating posi-tion to another. Unexpected triggering will discharge a nail, which may result in personal injury.
Hold the nailer by insulated gripping surfaces, when performing an operation where the nail may contact hidden wiring. A nail contacting a “live” wire may make exposed metal parts of the nailer “live” and could give the operator an electric shock.
Hold the nailer with a firm grasp during operation. Uncontrolled recoil of the nailer may result in unintended activation, which may result in personal injury.
Keep all body parts such as hands and legs, etc. away from the firing direction of the tool. The nail may penetrate the workpiece as well as any object behind it, which may result in personal injury.
When using the nailer, keep all body parts such as hands and legs, etc. away from the area where the nails is driven into the workpiece. The nail could deflect and exit the workpiece, which may result in personal injury.
Use suitable detectors to determine if there are hidden supply lines or contact the local utility company for assistance. Contact with electric cables can cause fire and electric shock. Damaging gas lines can lead to explosion. Breaking water pipes causes property damage.
In case of damage and improper use of the battery, vapors may be emitted. The battery can set alight or explode. Ensure the area is well-ventilated and seek medical attention should you experience any adverse effects. The vapors may irritate the respiratory system.
Do not modify or open the battery. There is a risk of short-circuiting.
The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.
Only use the battery in the manufacturer’s products. This is the only way in which you can protect the battery against dangerous overload.
Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short-circuiting.
Do not use the power tool and the nails on very soft materials (e.g. wood, lightweight construction materials). The nails may penetrate the substrate and may cause injury.
Do not use the power tool and the nails on very hard materials (e.g. high-strength steel, very hard natural stone) or on types of concrete with high compressive strength or aggregate with high compressive strength. If the material is too hard, the nail may ricochet, break and escape and may hit you or other persons and may cause injuries.
Never hold the power tool when it is at an acute angle to the substrate. The power tool must be perpendicular to the substrate. There must be no contamination on the substrate.
Do not deactivate or remove the contact element. The contact element is a safety mechanism to reduce the risk of unintentional triggering. Deactivating this component may lead to unintentional triggering.
Only use the power tool if the contact element is functioning correctly. If the contact element is defective, the power tool may trigger unexpectedly.
Always fill the magazine of the power tool with nails first before you insert the battery. This reduces the risk of accidentally discharging a nail and injuring yourself or other people.
Never discharge nails in the vicinity of flammable materials. When driving in some nail types, sparks may fly out of the contact element.
Never discharge a nail on top of another nail. This may lead to the nail being deflected or the power tool reacting unexpectedly.

Noise/Vibration Information

Noise emission values determined according to EN 60745‑2‑16.

Typically, the A-weighted noise level of the power tool is:
- Sound pressure level 85 dB(A); sound power
- level 96 dB(A). Uncertainty K = 3 dB.

Wear hearing protection!

Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745‑2‑16:
- ah = 5.7 m/s2, K = 1.5 m/s2.

The vibration level and noise emission value given in these instructions have been measured in accordance with a standardized measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different accessories or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period.
To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and accessories, keeping their hands warm, and organising workflows correctly.

Starting Operation

Switching On and Off

To switch on the power tool, press the on/off button (1) on the user interface until the user interface lights up.
To switch off the power tool, press the on/off button (1) again.
The power tool switches off automatically after 30 min if it is not being used.

Checking the Suitability of the Substrate

Check the suitability of the substrate before loading the power tool with nails or performing fastening.
The substrate must be level and free from residue.
To check the hardness of the substrate material, use a nail as a centre punch. Use a hammer to hit it with a powerful strike on the material. Check the result:

The point of the nail is blunted: The substrate is too hard and not suitable; the nail may ricochet.
The material tears or splinters: The substrate is too brittle and is not suitable. Particles may hit you or other people, or the nail may completely penetrate the substrate.
When struck with a hammer, the nail sinks into the substrate: The substrate is too soft and is not suitable; the nail may fully penetrate the substrate.
The nail leaves behind a small recess in the substrate: The substrate is suitable for fastening.

Initiating the Discharging Procedure

Switch on the power tool.
Press the unlocking switch (5) to the left to unlock the trigger (6) (see figure D).
Ensure that you hold the power tool by the handle (7) with a firm grip.
Press the contact element (17) all the way to the substrate.
When the contact element is pressed, the worklight (19) lights up and illuminates the work area in poor lighting conditions.
Afterwards, briefly press the trigger (6) and release it again. This discharges a nail into the substrate.
Note: The trigger (6) must be pressed within 2 s after pressing the contact element (17). Otherwise, the power tool goes into safe mode and the discharging process must be restarted.
For another driving procedure, lift the power tool fully off the substrate and position it firmly at the next required location.
During work breaks and when work is finished, secure the trigger (6) by pressing the unlocking switch (5) to the right (see figure D).

Note

Securing prevents triggering if the contact element (17) is not fully pressed or the trigger (6) has not been released between discharging procedures.

Working Advice

Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from unintentionally pressing the on/off switch.

Before starting work, always check that the safety and actuation devices are functioning correctly and that all screws and nuts are tightly seated.
If a power tool is defective or not functioning properly, disconnect it immediately from the power supply and contact an authorised Bosch after-sales service centre.
Do not perform any incorrect manipulations on the power tool. Do not disassemble or block any components of the power tool. Do not carry out “emergency repairs” with unsuitable means.

Avoid any tampering and damage to the power tool, e. g. from:

Imprinting or engraving,
Retrofitting measures not approved by the manufacturer,
Dropping on or sliding over the floor,
Using as a hammer,
Applying any kind of force.

For longer work breaks and after finishing work, switch off the power tool, remove the battery and empty the magazine if possible.

Requirements for Discharging Procedures

When fastening, observe the manufacturer’s specifications for the material being fastened, as well as the construction plans for the systems.
Make sure to check whatever is below or behind your workpiece.
Do not insert nails into walls, ceilings or floors when persons are behind them. The nails may punch through the substrate and may cause injury.
The nails must always be discharged into the substrate at a perpendicular angle.
Do not insert a nail on top of one that has already been inserted.
This could cause the nail to deform, the nails could become jammed or the power tool could move in an uncontrolled manner.
Check whether the nails have been inserted correctly. For fastening to be secure, they must sit neither too high nor too low nor be bent.
GNB 18V‑40: When attaching fastening elements, also check that the nails have been set correctly. If concrete is damaged by failed nails, it must be repaired in accordance with recognised rules.
