The technical documentation is filed and stored here:
These safety instructions apply for fastening tools with and without magazine.
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 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. When inserting/loading an application-specific type of fastener, never press
a hand or any other part of the body against the fastener guide.
▶ Never point the fastening tool towards yourself or any other person.
▶ Keep your arms flexed when operating the tool (do not straighten the arms).
▶ When pulling back the nail pusher, always take care to ensure that it engages.
▶ When disengaging the nail pusher, do not release it and allow it to jump forward. Guide it forward
slowly. There is a risk of pinching the fingers.
▶ 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. 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 safety trigger only when the fastening tool is pressed against the working surface in such a way
that the fastener guide is pushed into the tool as far as it will go.
▶ Always wear gloves if you have to carry out maintenance work on the fastening tool while it is still
hot.
▶ 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 may cause flying fragments or result in parts of the nail strip material being forcibly
ejected from the tool. Flying fragments present a risk of injury to the body and eyes. Wear eyeprotection, 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.
▶ Wear suitable ear protection ( see noise information in the technical data section). Fasteners are driven
through ignition of a gas/air mixture. The resulting noise exposure may cause damage to the hearing.
Other persons in the vicinity should also wear suitable hearing protection.
▶ When driving a fastener, always hold the fastening tool securely and at right angles to the supporting
material. This helps to avoid deflection of the fastener by the supporting material.
▶ Never drive a second fastener at the same location. This may lead to breakage or jamming of fasteners.
▶ Always remove the gas can and battery and empty the magazine before changing the magazine and
before undertaking cleaning, servicing or maintenance work, in preparation for storage or transport and
before leaving the fastening tool unattended.
▶ 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.
▶ 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.
▶ Check that the tool is switched off before inserting the battery. Inserting a battery into an electric
tool that is switched on can lead to 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.
▶ Avoid short circuiting the battery terminals. Check that the contacts on the battery and on the tool
are free from foreign objects before inserting the battery into the tool. Short circuiting the battery
terminals presents a risk of fire, explosion and chemical burns.
▶ Do not continue to use or attempt to charge damaged batteries (e.g. batteries with cracks, broken
parts, bent or pushed-in / pulled-out contacts).
▶ A battery that is too hot to hold 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.
Instructions for handling the propellant gas
▶ Observe the instructions printed on the gas can and in the accompanying information.
▶ Escaping gas is harmful to the lungs, skin and eyes. Keep your face and eyes away from the gas can
compartment for up to about 10 seconds after removing the gas can.
▶ Do not operate the gas can valve manually.
▶ 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 doctor 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.
General instructions concerning personal safety
▶ Take care to adopt an ergonomic body position. Work from a safe stance and take care to stay in balance
at all times. This will allow you to control the fastening tool better, even in unexpected situations.
▶ Keep other people away from the working area, especially children.
