Hilti DX 6 Mode D'emploi page 25

Malfunction
The fastener is not driven
flush
Concrete spalling
Damaged fastener head
The nail doesn't penetrate
deeply enough
The fastener doesn't hold in
the base material
Fastener breakage
(shear breakage)
Fastener breakage
(with deformation)
*2232123*
Possible cause
A rebar is located just below the
concrete surface.
Hard material (steel, concrete).
Hard and/or large aggregates in
the concrete.
Too much driving energy.
The wrong piston has been fitted.
The piston is damaged.
Driving energy too low
The application limits have been
exceeded (very hard material).
The system is unsuitable.
Thin supporting steel (4­5 mm)
Driving energy too low
The application limits have been
exceeded (very hard material).
Driving energy too low
The application limits have been
exceeded (very hard material).

Action to be taken
▶ Drive the fastener at a different
position.
▶ Turn the selector ring for driving
energy to increase driving
energy.
▶ Use a shorter nail.
▶ Use a nail with a higher
application limit.
▶ For concrete: Use the DX-Kwik
method (predrilling) → see the
'Direct Fastening Technology
Manual'.
▶ Use the DX-Kwik method
(predrilling).
▶ Turn the selector ring for driving
energy to reduce driving energy.
▶ Make sure that the correct
piston / fastener combination is
used.
▶ Change the piston.
▶ Turn the selector ring for driving
energy to increase driving
energy.
▶ Use an extra-strong cartridge.
▶ Use a nail with a higher
application limit.
▶ Use a more powerful system ,
e.g. DX 76 (PTR).
▶ Use a different energy setting.
▶ Use a nail suitable for thin
supporting steel.
▶ Turn the selector ring for driving
energy to increase driving
energy.
▶ Use an extra-strong cartridge.
▶ Use a more powerful system,
e.g. DX 76 (PTR), with corre-
sponding suitable fasteners.
