2 Safety
2.1 Safety precautions
Working safely with the setting tool
▶ Pressing the nosepiece of the setting 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 setting tool towards yourself or any other person.
▶ Keep your arms flexed when operating the tool (do not straighten the arms).
▶ Stay alert, watch what you are doing and use common sense when operating the setting tool. Do
not use the setting tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating the setting tool may result in serious personal injury.
▶ 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.
▶ Only activate the trigger when the setting tool is pressed against the base material in such a way that the
fastener guide is plunged into the setting tool as far as it will go.
▶ Always wear gloves if you have to carry out maintenance work on the setting 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.
Printed: 28.09.2017 | Doc-Nr: PUB / 5332417 / 000 / 01
English 3
▶ If the setting 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 a suitable
form of eye protection, ear protectors and a hard hat. Depending on the application and type of tool
in use, wearing personal protective equipment such as a dust mask, non-slip safety footwear, hard hat
or suitable eye protection 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). The fastener is driven
by the energy released on 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 ear protection.
▶ When driving a fastener, always hold the setting 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.
▶ Never attempt to redrive a previously driven stud or nail. Re-use of a fastener may cause it to break,
thereby presenting a risk of injury.
▶ Alway remove the gas can and ( → page 8) empty the magazine ( → page 8) before changing the magazine,
before cleaning, servicing or maintenance work on the tool, before storage or transport and before leaving
the setting tool unattended.
▶ After use, lay the tool flat on the floor. A tool that is mounted on a pole tool extension and left leaning
against a wall presents a risk of injury as it may fall over.
▶ When lowering (tilting) the pole tool extension, do not hold the pole only at its lower end. The considerable
leverage exerted may cause you to lose control over the tilting movement of the pole and tool. This may
result in injury and damage to the equipment or other property.
▶ To ensure that the setting 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 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 setting tool repaired only by trained and qualified specialists using genuine Hilti spare parts.
This will ensure that the safety of the setting tool is maintained.
▶ Tampering with or modification of the setting tool is not permissible.
▶ Do not use the setting tool where there is a risk of fire or explosion.
▶ Take influences of the surrounding area into account. Do not expose the setting tool to rain or snow and
do not use it in damp or wet conditions.
▶ Use the setting 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 → page 4.
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 setting 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 tool also to become live, leading to a risk of electric shock.
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.
