Working safely with the fastening tool

• Pressing the nosepiece of the fastening tool against a part of the body may lead to serious injury due to inadvertent actuation and release of a fastener. Never press the nosepiece of the tool against your hand or any other part of the body.
  
• When you are positioning a fastener ready for driving, take your finger off the trigger and do not apply too much pressure to the fastener guide. When inserting/loading application-specific fasteners (e.g. washers, clips or clamps, etc.) in/on the fastener guide there is a risk of serious injury due to inadvertent actuation of the tool resulting in discharge of a fastener.
  
• Never point the fastening tool towards yourself or any other person.
  
• Keep your arms flexed when operating the tool (do not straighten the arms).
  
• Always keep the fastening tool firmly under control every time you drive a fastener and hold it vertical to and steadily against the working surface. This will help to prevent the fastener being deflected by the base material.
  
• When pulling back the nail pusher, always take care to ensure that it engages.
  
• Before you drive a fastener, check that when the tool is fired there is no risk to persons or objects in front of, behind or below the working area. It is not permissible for persons or parts of the body to be behind the work surface into which a fastener is going to be driven.
  
• Do not attempt to drive fasteners into materials that are too hard , such as welded steel or cast steel. Attempting to drive fasteners into these materials may lead to malfunctions, incorrectly driven fasteners or breakage of fasteners.
  
• Do not attempt to drive fasteners into materials that are too soft , such as wood or drywall/gypsum board without the adequate support of carrier material. Attempting to drive fasteners into these materials may lead to malfunctions and fasteners being driven incorrectly or driven right through the material.
  
• Do not attempt to drive fasteners into materials that are too brittle , such as glass or tiles. Attempting to drive fasteners into these materials may lead to malfunctions, fasteners being driven incorrectly and may cause the material to shatter.
  
• Before driving fasteners, check that there is no risk of injuring persons or of damaging objects present behind or below the working surface.
  
• Pull the trigger only when the fastening tool is at right angles to and pressed fully against the work surface.
  
• If fasteners are driven at a high rate or if the tool used for a long period, surfaces of the tool beyond the grip areas may get hot. Wear protective gloves to avoid burning injuries.
  
• If the fastening tool overheats, remove the gas can and allow the tool to cool down. Do not exceed the specified maximum fastener driving rate.
  
• Driving fasteners can cause forcible ejection of fragments, for example from the material, fasteners or magazine strip. Flying fragments present a risk of injury to the body and eyes. Wear eye protection, ear protection and a hard hat. Depending on the application and type of fastening tool in use, wearing personal protective equipment such as a dust mask, non-slip safety footwear, hard hat and ear protection reduces the risk of injury. Other persons in the vicinity must also wear eye protection and a hard hat.
  
• Never drive a second fastener at the same location. This may lead to breakage or jamming of fasteners.
  
• Always remove the gas can (instructions), battery (instructions) and magazine contents before you change the magazine or carry out cleaning and maintenance work. Remove the gas can, battery and magazine contents whenever you are going to leave the fastening tool unattended, transport it or put it into storage.
  
• Risk of bursting due to exposure to heat! Protect fastening tool, accessories and consumables against exposure to strong heat from heat sources such as naked flames, heating elements, soldering and welding equipment.
  
• To ensure that the fastening tool functions faultlessly and as intended, always check the tool and accessories for possible damage before use. Check that moving parts function faultlessly, without sticking, and that no parts are damaged. In order to ensure faultless operation of the fastening tool, all parts must be fitted correctly and must meet the necessary requirements. Damaged protective devices or other parts must be properly repaired or replaced by Hilti Service unless otherwise stated in the operating instructions.
  
• Have the fastening tool repaired only by trained and qualified specialists using genuine Hilti spare parts. This will ensure that the safety of the fastening tool is maintained.
  
• Tampering with or modification of the fastening tool is not permissible.
  
• Do not use the fastening tool where there is a risk of fire or explosion.
  
• Take influences of the surrounding area into account. Do not expose the fastening tool to rain or snow and do not use it in damp or wet conditions.
  
• Use the fastening tool only in well-ventilated working areas.
  
• Select the correct combination of fastener guide and fastener. The wrong combination may result in damage to the tool and in reduced fastening quality.
  
• Do not overload the tool. Use the correct tool for the job. The correct tool will do the job better and more safely within the performance range for which it is designed.
  
• Always observe the application guidelines.
  

Hazards presented by electricity

• Before beginning work, check the working area (e.g. using a metal detector) to ensure that no concealed electric cables or gas and water pipes are present.
  
• Hold the fastening tool only by the insulated grip when working in areas where fasteners may be driven inadvertently into concealed electric cables. Contact with a live electric cable may cause metal parts of the fastening tool also to become live, leading to a risk of electric shock.
  
• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, cookers, stoves and refrigerators. There is an increased risk of electric shock if your body is grounded.
  

Use and care of battery-powered tools

• Avoid accidental starting. Carrying power tools with your finger on the switch or plugging in power tools that are already switched on invites accidents.
  
• Do not expose batteries to high temperatures, the direct heat of the sun, and keep them away from fire. There is a risk of explosion.
  
• Do not disassemble, squash or incinerate batteries and do not subject them to temperatures over 80°C. This presents a risk of fire, explosion or injury through contact with caustic substances.
  
• Avoid ingress of moisture. Ingress of moisture may cause a short circuit, resulting in burning injuries or fire.
  
• Use only batteries of the type approved for use with the applicable tool. Use of other batteries or use of the batteries for purposes for which they are not intended presents a risk of fire and explosion.
  
• Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
  
• Remove the battery from the tool before transport or storage.
  
• When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws and other small metal objects that could cause bridging between the terminals. A short circuit between the battery terminals may cause burns or a fire.
  
• Do not attempt to charge or continue to use damaged batteries (e.g. batteries with cracks, broken parts, bent or pushed-in and/or pulled-out contacts).
  
• A battery that is too hot to touch may be defective. Allow the battery to cool down in a place where there is no risk of causing a fire. Check that there are no flammable materials nearby. Contact Hilti Service.
  
• Misuse can result in liquid escaping from the battery. Avoid contact with the liquid. If contact accidentally occurs, rinse with water. Seek medical attention if the liquid comes into contact with the eyes. Liquid ejected from the battery may cause skin irritation or burns.
  

Instructions for handling the propellant gas

• Observe the safety instructions printed on the gas can and in the accompanying information.
  
• The gas is highly flammable. Keep the gas can away from open flames and other sources of ignition.
  
• Escaping gas is harmful to the lungs, skin and eyes and can cause cold injuries and burns. Keep your face and eyes away from the metering valve and the gas can compartment for up to approximately 10 seconds after removing the gas can.
  
• Never attempt to remove or manually operate the metering valve of a gas can that has been prepared for use or is in use. Considerable quantities of pressurized liquefied gas could escape, endangering you and other persons.
  
• If a person has inhaled gas, take the person into the open air or into a well-ventilated area and place the person in a comfortable position. Consult a physician if necessary.
  
• Call a doctor if the person is unconscious. Bring the person into a well-ventilated area and place the person in the stable recovery position (i.e. lying on the side). If the person is not breathing, administer artificial respiration and, if necessary, supply oxygen.
  
• After eye contact with gas, rinse the open eyes thoroughly under running water for several minutes.
  
• After skin contact with gas, wash the contact area carefully with soap and warm water. Subsequently apply a skin cream.
