5 Safety instructions

5.1 Basic information concerning safety

In addition to the information relevant to safety given in each of thesections ofthese operatinginstructions, the following points must be strictly observed at all times.

5.1.1 Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a direct fastening tool. Do not use a tool while you are tired or under the influence of drugs, alcohol or medication.

A moment of inattention while operating tools may result in serious personal injury.

b) Avoid unfavorable body positions. Make sure you

work from a safe stance and stay in balance at all times.

c) Never point the tool toward yourself or other per-

sons.

d) Neverpress the nosepiece of thetool against your

hand or against any other part of your body (or other person’s hand or part of their body).

e) Keep other persons, especially children, away

from the area in which the work is being carried out.

5.1.2 Fastening tool use and care

a) Use the right tool for the job. Do not use the tool

for purposes for which it was not intended. Use it only as directed and when in faultless condition.

b) Pressthe tool against theworking surface at right

angles.

c) Never leave a loaded tool unattended. d) Remove the gas can from the tool before trans-

porting the tool.

e) Always unload the tool (remove the gas can and

fasteners) before cleaning, before carrying out care and maintenance, before work breaks and before storing the tool.

f) When not in use, tools must be unloaded and

stored in a dry place, locked up or out of reach of children.

g) Check the tool or machine and its accessories for

damage and ensure that they function faultlessly

andas intended.Check thatmoving parts function correctly without sticking and that no parts are damaged. All parts must be fitted correctly and fulfill all conditions necessary for correct operation of the tool. Damaged guards, safety devices and other parts must be repaired or replaced properly at a Hilti service center unless otherwise indicated in the operating instructions.

h) Keep the arms slightly bent while operating the

tool (do not straighten the arms).

i) Pull the trigger only when the tool is pressed

against the working surface at right angles.

j) Always hold the tool securely and at right angles

to the working surface when driving a fastener. This will helpto prevent fasteners being deflected by the working surface.

k) Never redrive a fastener. This may cause the

fastener to break and the tool may jam.

l) Never drive fasteners into existing holes unless

this is recommended by Hilti.

m) Always observe the application guidelines.

5.1.3 Work area safety

a) Ensure that the workplace is well lit. b) Operate the tool only in well-ventilated working

areas.

c) Do not attempt to drive fasteners into unsuitable

materials. Materials that are too hard, e.g. welded

steel and cast iron. Materials that are too soft, e.g. wood and drywall panel (gypsum board). Materials that are too brittle, e.g. glass and ceramic tiles. Driving a fastener into these materials may cause the fastener to break, shatter or to be driven right through.

d) Before driving fasteners, check that no one is

present immediately behind or below the working surface.

e) Keep the workplace tidy. Objects which could

cause injury should be removed from the working area. Untidiness at the workplace can lead to

accidents.

f) Keep the grips dry, clean and free from oil and

grease.

g) Wear non-skid shoes. h) Take the influences of the surrounding area into

account. Do not expose the tool to rain or snow and do not use it in damp or wet conditions. Do notusethetoolwherethereisariskoffireor explosion.

5.1.4 Mechanical hazards

a) Select the correct fastener guide and fastener

combination for the job on hand. Failure to use

the correct combination of these items may result in damage to the tool and/or unsatisfactory fastening quality.

b) Useonly fasteners of a type approved for usewith

the tool.

c) Never fill the magazine with fasteners unless it is

correctly fitted to the tool. The fasteners could be ejected uncontrollably.

5.1.5 Thermal hazards

a) If the tool has overheated, allow it to cool down.

Do not exceed the recommended fastener driving rate.

b) Always wear gloves if the tool has to be dis-

mantled for cleaning or maintenance before it has been allowed to cool down.

5.1.6 Gasses

Liquid gas under pressure: Observe the hazard warnings and first-aid instructions printed on the gas can and in the instructions for use.

The gas is extremely flammable (contains: isobutane, propene). Refilling the gas can is not permissible.

a) Do not use damaged gas cans. b) Do not attempt to force the gas can open. Do not

incinerate or crush the can and do not attempt to reuse it for any other purpose.

c) Neverspray the gastoward personsor otherliving

beings.

d) Keep the gas away from all sources of ignition

such as naked flames, sparks, pilot lights, static discharge and very warm surfaces.

e) Do not smoke while using the tool.

5.1.6.1 Storage

a) Do not store gas cans in inhabited rooms or in

rooms connected to inhabited rooms.

b) Store the gas cans in a dry, well-ventilated place. c) Store the gas cans out of reach of children. d) Do not expose gas cans to direct sunlight or

temperatures above 50°C (122°F).

e) Recommended storage temperature: 5°C to 25°C

(41°F to 77°F).

5.1.6.2 First aid

Read the material safety data sheet for information about use, care and maintenance and first-aid measures.

a) Direct skin contact with the liquid gas may cause

frostbite or a serious freezing injury similar to a burn.

b) In case of inhalation of the gas: The person af-

fected should be taken into the open air and brought into a comfortable position.

c) In case of unconsciousness: Bring the person af-

fected into a securerecovery position. Should the person stop breathing, apply artificial respiration and supply oxygen if necessary.

d) In case of gas contact with the eyes: Rinse the

open eyes under running water for one minute.
