4.1 Fastener driving tool safety warnings
a) Always assume that the tool contains fasteners. Careless handling of the tool may result in unexpected firing of fasteners and personal injury.
b) Disconnect the tool from the power source when loading and unloading fasteners, making adjustments or changing accessories. The tool may be accidentally activated if it  is connected to the power source, which may result in personal injury.
c) Be careful when handling fasteners, especially when loading and unloading. The fasteners have sharp points which may result in personal injury.
d) Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge a fastener, which may result in personal injury.
e) Keep fingers away from the trigger when not operating the tool and when moving from one operating position to another. Unexpected triggering will discharge a fastener,  which may result in personal injury.
f) Hold the tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. A fastener contacting a “live” wire may make  exposed metal parts of the tool “live” and could give the operator an electric shock.
g) Hold the tool with a firm grasp during operation. Uncontrolled recoil of the tool may result in unintended activation, which may result in personal injury.
h) Keep all body parts such as hands and legs, etc. away from the firing direction of the tool. The fastener may penetrate the workpiece as well as any object behind it, which  may result in personal injury.
i) When using the tool, keep all body parts such as hands and legs, etc. away from the area where the fastener is driven into the workpiece.
The fastener could deflect and exit the workpiece, which may result in personal injury.
j) 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 fastener may be deflected away from the  workpiece, which may result in personal injury.
k) Do not use this tool 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.
l) Disconnect the tool from the power source if a fastener jams in the tool. While removing a jammed fastener, the tool may be accidentally activated if it is connected to the  power source, which may result in personal injury.
m) Use caution while removing a jammed fastener. The mechanism may be under compression and the fastener may be forcefully discharged, which may result in personal injury.

4.2 Additional Safety Instructions:
CAUTION! Keep away from children and frail persons. When not in use, keep the tool out of the reach of children and frail persons.
Safe operation through correct use. This tool is intended for driving in nails into wood or similar soft materials. Use is only for its intended purpose.
Protect yourself from fires and explosions. As sparks might fly around during the nailing process, it is dangerous to use the tool near varnishes, paints, petrol, thinners, fuels,  gas, adhesives or similar flammable substances as they might ignite or explode. For this reason, the tool must not be used near such flammable materials under any circumstances.

Protect your eyes with safety goggles.
When working with the tool, always wear protective goggles and make sure that persons in your vicinity also wear protective goggles. Parts of nails that have not been driven  in properly can enter the eyes and destroy your eyesight. Protective goggles are available in any specialized shop. Always wear safety eye protection, either safety glasses or a  wide-angle safety mask with the prescribed lenses. Employers must always prescribe the wearing of eye protection.
Protect your ears and your head. Wear hearing protection and safety helmets while nailing.
Depending on the conditions, people in the vicinity should also wear noise protection and safety helmets.

Pay attention to people working in your
vicinity. It can be dangerous if nails that have not been driven in properly injure other people. For this reason, pay attention to the safety of the people in your vicinity when  using this tool. Ensure that the mouth of the tool does not get anywhere persons, hands or feet.

Do not point the mouth of the tool at people.
Always assume that there are nails in the tool. If the mouth of the tool is pointed at people, serious accidents may occur if the tool is accidentally triggered. When inserting  and removing the battery pack, during nail reloading or similar operations, make sure that the nail outlet is not directed at any person (including yourself). Even if there are no nails in the tool, it is dangerous to trigger the tool while is it pointed at someone. Therefore, never try this. The tool is not a toy. Consider the tool exclusively as a working  tool and handle it accordingly.

Check the trigger safety lock before use.
Ensure that the trigger safety lock works properly. (The trigger safety lock can be referred to as “safety device”.) Never use the tool if the trigger safety lock is not working  properly, otherwise the tool could unexpectedly fire a nail. Do not change the trigger safety lock and do not remove it, otherwise the trigger safety lock can no longer be operated.
The selection of the triggering method is important. Read and understand the instructions in chapter 8.1.
Before using the tool, make sure that it is working properly. Carry out the tests in chapter 7.4 .
Use only the prescribed nails. Only the nails specified in the operating instructions may be used.

Be careful when inserting the battery pack.
When inserting the battery pack and filling the tool with nails make sure that you do not accidentally trigger the tool.
– Under any circumstances, do not touch the trigger.
– Ensure that the mouth does not get in contact with any object.
– Keep the mouth pointing downwards. It is important that you follow the above instructions and make sure that no body parts, hands or feet are in front of the mouth of the tool.

Never touch the trigger carelessly.
Only touch the trigger with your finger when nailing. If your finger is on the trigger while carrying the tool or handing it to someone, you may unintentionally fire a shot and cause an accident.

Firmly press the mouth against the material to be nailed.
When driving in nails, press the mouth firmly against the material to be nailed. If this is not done carefully, the nails may recoil.
Keep hands and feet away from the mouth while working. It is very dangerous if a nail enters the hands or feet through a mistake.

Protect yourself from tool kickback.
Do not approach the top of the tool with your head or any other part of your body while working. This is dangerous because the tool  can kickback violently if a nail hits a previously driven in nail or a hard branch in the wood.

Protect yourself from double shots due to tool kickback. If the trigger safety lock accidentally comes again into contact with the workpiece after kickback, a nail may fired  unintentionally. To avoid these unintentional double shots, pay attention to the following:
a) Working with “fully sequential triggering” operating mode
1. Pull the trigger fast and hard (4).
b) Working with “contact release” operating mode

1. Do not press the tool with excessive force against the wood.
2. Detach the tool from the wood when kickback starts after nailing.

Be careful when nailing thin boards or wooden edges.
When nailing thin boards, the nails can be fired through the boards, as it can also happen when nailing on wooden  edges due to ricochets. In such cases, make sure that no-one (including no hands, feet etc.) is behind the board or near the wood you are working on.

Simultaneous nailing on both sides of a wall is dangerous.
Under no circumstances nail simultaneously on both sides of a wall. This would be dangerous because the nails could be fired through the wall and thus cause injuries.

Do not use the tool in the “contact release (continuous operation)” operating mode on scaffolding or ladders. The tool must not be used for particular applications,  e.g.
– if changing the driving in location involves the use of scaffolding, stairs, ladders or ladder-like structures, e.g. roof battens.
– Closing of boxes or crates,
– appropriate transport safety systems, e.g. on vehicles and trolleys.

Remove all remaining nails and the battery pack from the tool, when:

1. you are carrying out maintenance and inspection work,
2.  your are checking the proper function of the trigger safety lock and trigger,
3. you are clearing a jam,
4. the tool is not in use,
5. you are leaving the working area,
6. you are taking the tool to a different location,
7. you are handing the tool to another person.
   Never try to remove a jam or repair the tool without first having removed the battery pack and all remaining nails from the tool.
   Never leave the tool unattended, since people who are not familiar with the tool could use it and injure themselves.

Remove the battery pack from the tool when:

1. you are refilling nails,
2. you are setting the nailing depth.

The permissible operating temperature of this tool is between 0°C and 40°C. Therefore, make sure to operate the tool only within this temperature range. It may happen that  the tool no longer functions below 0°C or above 40°C.
NEVER allow magnets (or similar magnetic parts) to be next to the tool as the tool has a magnetic sensor inside. This can lead to failure or risk of injury caused by the malfunction.
Allow the tool to rest after continuous operation.
The tool is equipped with a temperature protection casing to protect the motor.
Continuous work can cause the temperature of the tool to rise, which activates the temperature protection circuit and automatically stops operation. If this is the case, allow  the tool to cool down before using it again.
Do not subject the keypad to strong vibrationsor damage it. This may lead to a malfunction

4.3 Icons
Do not use on scaffolds or ladders.
Wear ear protectors.
WARNING – Always wear protective goggles.
Do not point the mouth of the tool at people.
Keep hands and feet away from the mouth while working.

4.4 Use only suitable nails
Choose suitable nails according to the figure and the technical data on page 3.
– Other types of nails may not be used. They may cause the tool to malfunction and/or the nails to break, which may result in serious injury.
– Use only smooth nails, barbed nails or ring-type nails.
– Do not use threaded nails.
– Use paper-connected nail strips (angle: 30°-34°, clipped nails).
– Handle nails and their packaging with care. If nails are dropped, the connecting strip can tear, resulting in faulty feeding of the nails and jams thereof.
– Never use nail strips with more than 10 nails.
– Use intact nail strips with nails of uniform length.

4.6 Reducing dust exposure:
WARNING – 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.
This also applies to dust from other materials, such as some timber types (like oak or beech dust), metals, asbestos. Other known diseases are e.g. allergic reactions, respiratory  diseases. Do not let dust enter the body.
Observe the relevant guidelines and national regulations for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).
Collect the particles generated at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter the environment in an uncontrolled manner.

Use a suitable extraction unit.
Reduce dust exposure with the following measures:

• do not direct the escaping particles and the exhaust air stream towards yourself or nearby persons or towards dust deposits,
•  use an extraction unit and/or an air purifier,
•  ensure good ventilation of the workplace and keep it clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
• Vacuum or wash protective clothing. Do not blow, beat or brush protective gear.

Clean the magazine. Remove any dust and wood chips that have accumulated in the magazine.
CAUTION! Check if the feed slide (14) glides smoothly by pulling it with your finger. If this is not the case, the nails can exit at an unusual angle and injure someone.
Clean the trigger safety lock (2) and maintain smooth running.

Inspection of the fixing screws
Regularly inspect all fixing screws and ensure that they are properly tightened.
If any of the screws become loose, tighten them again immediately. Failure to do so could lead to serious danger.

Exterior cleaning
If the tool is dirty, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chlorine  solvent, petrol or paint thinner as these soften plastics.
