Hilti DX 2 Operating Instructions Manual page 35

b) Avoid unfavorable body positions. Make sure you
work from a safe stance and stay in balance at all
times.
c) Wear non-skid shoes.
d) Never point the tool toward yourself or other per-
sons.
e) Never press the nosepiece of the tool against your
hand or against any other part of your body (or
other person's hand or part of their body).
f) Keep other persons, especially children, away
from the area in which the work is being carried
out.
g) Keep the arms slightly bent while operating the
tool (do not straighten the arms).
h) Observe the information printed in the operating in-
structions concerning operation, care and mainten-
ance.
1.1.4 Use and care of powder-actuated fastening
tools
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) Never leave a loaded tool unattended.
c) Store unused cartridges and tools currently not in
use in a dry place where they are not exposed to
high temperatures.
d) Transport and store the tool in a toolbox that can be
secured to prevent unauthorized use.
e) Always unload the tool (remove cartridges and
fasteners) before cleaning, before maintenance,
before work breaks and before storing the tool.
When not in use, tools must be unloaded and
f)
stored in a dry place, locked up or out of reach of
children.
g) Check the tool and its accessories for any dam-
age. Guards, safety devices and any slightly worn
parts must be checked carefully to ensure that
they function faultlessly and as intended. Check
that moving parts function correctly without stick-
ing and that no parts are damaged. All parts must
be fitted correctly and fulfill all conditions neces-
sary 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 operat-
ing instructions.
h) Pull the trigger only when the tool is fully pressed
against the working surface at right angles.
Always hold the tool securely and at right angles
i)
to the working surface when driving in fasteners.
This will help to prevent fasteners being deflected
by the working surface.
j) Never redrive a fastener. This may cause the
fastener to break and the tool may jam.
k) Never drive fasteners into existing holes unless
this is recommended by Hilti.
l) Always observe the application guidelines.
m) Use the spall guard when the application permits.
n) Never pull the fastener guide or the fastener back
by hand as this could make the tool ready to fire.
This could cause a fastener or the piston to be
driven into a part of the body.
1.1.5 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) Never attempt to drive fasteners into materials
such as glass, marble, plastic, bronze, brass,
copper, rock, insulation material, hollow brick,
ceramic brick, thin sheet metal (< 4 mm), cast
iron or cellular concrete.
e) Before driving fasteners, check that no one is
present immediately behind or below the working
surface.
f) Keep the workplace tidy. Objects which could
cause injury should be removed from the work-
ing area. Untidiness at the workplace can lead to
accidents.
g) Keep the grips dry, clean and free from oil and
grease.
h) Do not use the tool where there is a risk of fire or
explosion unless it has been specially approved
for use under these conditions.
i) Concealed electric cables or gas and water pipes
present a serious hazard if damaged while you
are working. Accordingly, check the area in which
you are working beforehand (e.g. using a metal
detector). External metal parts of the tool or machine
may become live, for example, when an electric cable
is damaged accidentally.
j) Use the fasteners only within the recommended
temperature range. Always observe the inform-
ation given in the operating instructions. Plastic
parts can break and splinter at low temperatures.
1.1.6 Mechanical safety precautions
a) Use only fasteners of a type approved for use with
the tool.
b) Do not tamper with or modify the tool or parts of
it, especially the piston.
1.1.7 Thermal safety precautions
a) If the tool has overheated, allow it to cool down.
Do not exceed the recommended fastener driving
rate.
b) Do not dismantle the tool while it is hot. Allow the
tool to cool down.
c) The tool must be allowed to cool down if the
plastic cartridge strip begins to melt.
